# MCP Atlassian INTSIG

Model Context Protocol (MCP) server for Atlassian products (Confluence and Jira). This integration supports both Confluence & Jira Cloud and Server/Data Center (extra support Confluence with INTSIG SSO) deployments.

## Example Usage

Ask your AI assistant to:

- **📝 Automatic Jira Updates** - "Update Jira from our meeting notes"
- **🔍 AI-Powered Confluence Search** - "Find our OKR guide in Confluence and summarize it"
- **🐛 Smart Jira Issue Filtering** - "Show me urgent bugs in PROJ project from last week"
- **📄 Content Creation & Management** - "Create a tech design doc for XYZ feature"

## Quick Start Guide

### 🔐 1. Authentication Setup

MCP Atlassian supports three authentication methods:

#### A. INTSIG Personal Account (INTSIG Confluence)

1. Use your INTSIG personal account, such as <xxx_xx@intsig.net, pwd>

#### B. API Token Authentication (Cloud)

1. Go to https://id.atlassian.com/manage-profile/security/api-tokens
2. Click **Create API token**, name it
3. Copy the token immediately

#### C. Personal Access Token (Server/Data Center)

1. Go to your profile (avatar) → **Profile** → **Personal Access Tokens**
2. Click **Create token**, name it, set expiry
3. Copy the token immediately

#### D. OAuth 2.0 Authentication (Cloud)

> [!NOTE]
> OAuth 2.0 is more complex to set up but provides enhanced security features. For most users, API Token authentication (Method A) is simpler and sufficient.

1. Go to [Atlassian Developer Console](https://developer.atlassian.com/console/myapps/)
2. Create an "OAuth 2.0 (3LO) integration" app
3. Configure **Permissions** (scopes) for Jira/Confluence
4. Set **Callback URL** (e.g., `http://localhost:8080/callback`)
5. Run setup wizard:
   ```bash
   docker run --rm -i \
     -p 8080:8080 \
     -v "${HOME}/.intsig-mcp-atlassian:/home/app/.intsig-mcp-atlassian" \
     registry.intsig.net/confluence-mcp/confluence-mcp:latest --oauth-setup -v
   ```
6. Follow prompts for `Client ID`, `Secret`, `URI`, and `Scope`
7. Complete browser authorization
8. Add obtained credentials to `.env` or IDE config:
   - `ATLASSIAN_OAUTH_CLOUD_ID` (from wizard)
   - `ATLASSIAN_OAUTH_CLIENT_ID`
   - `ATLASSIAN_OAUTH_CLIENT_SECRET`
   - `ATLASSIAN_OAUTH_REDIRECT_URI`
   - `ATLASSIAN_OAUTH_SCOPE`

> [!IMPORTANT]
> For the standard OAuth flow described above, include `offline_access` in your scope (e.g., `read:jira-work write:jira-work offline_access`). This allows the server to refresh the access token automatically.

<details>
<summary>Alternative: Using a Pre-existing OAuth Access Token (BYOT)</summary>

If you are running intsig-mcp-atlassian part of a larger system that manages Atlassian OAuth 2.0 access tokens externally (e.g., through a central identity provider or another application), you can provide an access token directly to this MCP server. This method bypasses the interactive setup wizard and the server's internal token management (including refresh capabilities).

**Requirements:**
- A valid Atlassian OAuth 2.0 Access Token with the necessary scopes for the intended operations.
- The corresponding `ATLASSIAN_OAUTH_CLOUD_ID` for your Atlassian instance.

**Configuration:**
To use this method, set the following environment variables (or use the corresponding command-line flags when starting the server):
- `ATLASSIAN_OAUTH_CLOUD_ID`: Your Atlassian Cloud ID. (CLI: `--oauth-cloud-id`)
- `ATLASSIAN_OAUTH_ACCESS_TOKEN`: Your pre-existing OAuth 2.0 access token. (CLI: `--oauth-access-token`)

**Important Considerations for BYOT:**
- **Token Lifecycle Management:** When using BYOT, the MCP server **does not** handle token refresh. The responsibility for obtaining, refreshing (before expiry), and revoking the access token lies entirely with you or the external system providing the token.
- **Unused Variables:** The standard OAuth client variables (`ATLASSIAN_OAUTH_CLIENT_ID`, `ATLASSIAN_OAUTH_CLIENT_SECRET`, `ATLASSIAN_OAUTH_REDIRECT_URI`, `ATLASSIAN_OAUTH_SCOPE`) are **not** used and can be omitted when configuring for BYOT.
- **No Setup Wizard:** The `--oauth-setup` wizard is not applicable and should not be used for this approach.
- **No Token Cache Volume:** The Docker volume mount for token storage (e.g., `-v "${HOME}/.intsig-mcp-atlassian:/home/app/.intsig-mcp-atlassian"`) is also not necessary if you are exclusively using the BYOT method, as no tokens are stored or managed by this server.
- **Scope:** The provided access token must already have the necessary permissions (scopes) for the Jira/Confluence operations you intend to perform.

This option is useful in scenarios where OAuth credential management is centralized or handled by other infrastructure components.

> [!TIP]
> **Multi-Cloud OAuth Support**: If you're building a multi-tenant application where users provide their own OAuth tokens, see the [Multi-Cloud OAuth Support](#multi-cloud-oauth-support) section for minimal configuration setup.

### 📦 2. Installation

MCP Atlassian is distributed as a Docker image. This is the recommended way to run the server, especially for IDE integration. Ensure you have Docker or Podman installed.

```bash
# Pull Pre-built Image
docker pull registry.intsig.net/confluence-mcp/confluence-mcp:latest
```

## 🛠️ IDE Integration

MCP Atlassian is designed to be used with AI assistants through IDE integration.

> [!TIP]
> **For Claude Desktop**: Locate and edit the configuration file directly:
> - **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
> - **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
> - **Linux**: `~/.config/Claude/claude_desktop_config.json`
>
> **For Cursor**: Open Settings → MCP → + Add new global MCP server

### ⚙️ Configuration Methods

There are two main approaches to configure the Docker container:

1. **Passing Variables Directly** (shown in examples below)
2. **Using an Environment File** with `--env-file` flag (shown in collapsible sections)

> [!NOTE]
> Common environment variables include:
>
> - `CONFLUENCE_SPACES_FILTER`: Filter by space keys (e.g., "DEV,TEAM,DOC")
> - `JIRA_PROJECTS_FILTER`: Filter by project keys (e.g., "PROJ,DEV,SUPPORT")
> - `READ_ONLY_MODE`: Set to "true" to disable write operations
> - `MCP_VERBOSE`: Set to "true" for more detailed logging
> - `MCP_LOGGING_STDOUT`: Set to "true" to log to stdout instead of stderr
> - `ENABLED_TOOLS`: Comma-separated list of tool names to enable (e.g., "confluence_search,jira_get_issue")
>
> See the [.env.example](https://github.com/sooperset/intsig-mcp-atlassian/blob/main/.env.example) file for all available options.

    }
  }
}
```

> [!NOTE]
> Set `CONFLUENCE_SSL_VERIFY` and `JIRA_SSL_VERIFY` to "false" only if you have self-signed certificates.

<details>
<summary>OAuth 2.0 Configuration (Cloud Only)</summary>
<a name="oauth-20-configuration-example-cloud-only"></a>

These examples show how to configure `intsig-mcp-atlassian` in your IDE (like Cursor or Claude Desktop) when using OAuth 2.0 for Atlassian Cloud.

**Example for Standard OAuth 2.0 Flow (using Setup Wizard):**

This configuration is for when you use the server's built-in OAuth client and have completed the [OAuth setup wizard](#c-oauth-20-authentication-cloud---advanced).

```json
{
  "mcpServers": {
    "intsig-mcp-atlassian": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-v", "<path_to_your_home>/.intsig-mcp-atlassian:/home/app/.intsig-mcp-atlassian",
        "-e", "JIRA_URL",
        "-e", "CONFLUENCE_URL",
        "-e", "ATLASSIAN_OAUTH_CLIENT_ID",
        "-e", "ATLASSIAN_OAUTH_CLIENT_SECRET",
        "-e", "ATLASSIAN_OAUTH_REDIRECT_URI",
        "-e", "ATLASSIAN_OAUTH_SCOPE",
        "-e", "ATLASSIAN_OAUTH_CLOUD_ID",
        "registry.intsig.net/confluence-mcp/confluence-mcp:latest"
      ],
      "env": {
        "JIRA_URL": "https://your-company.atlassian.net",
        "CONFLUENCE_URL": "https://your-company.atlassian.net/wiki",
        "ATLASSIAN_OAUTH_CLIENT_ID": "YOUR_OAUTH_APP_CLIENT_ID",
        "ATLASSIAN_OAUTH_CLIENT_SECRET": "YOUR_OAUTH_APP_CLIENT_SECRET",
        "ATLASSIAN_OAUTH_REDIRECT_URI": "http://localhost:8080/callback",
        "ATLASSIAN_OAUTH_SCOPE": "read:jira-work write:jira-work read:confluence-content.all write:confluence-content offline_access",
        "ATLASSIAN_OAUTH_CLOUD_ID": "YOUR_CLOUD_ID_FROM_SETUP_WIZARD"
      }
    }
  }
}
```

> [!NOTE]
> - For the Standard Flow:
>   - `ATLASSIAN_OAUTH_CLOUD_ID` is obtained from the `--oauth-setup` wizard output or is known for your instance.
>   - Other `ATLASSIAN_OAUTH_*` client variables are from your OAuth app in the Atlassian Developer Console.
>   - `JIRA_URL` and `CONFLUENCE_URL` for your Cloud instances are always required.
>   - The volume mount (`-v .../.intsig-mcp-atlassian:/home/app/.intsig-mcp-atlassian`) is crucial for persisting the OAuth tokens obtained by the wizard, enabling automatic refresh.

**Example for Pre-existing Access Token (BYOT - Bring Your Own Token):**

This configuration is for when you are providing your own externally managed OAuth 2.0 access token.

```json
{
  "mcpServers": {
    "intsig-mcp-atlassian": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e", "JIRA_URL",
        "-e", "CONFLUENCE_URL",
        "-e", "ATLASSIAN_OAUTH_CLOUD_ID",
        "-e", "ATLASSIAN_OAUTH_ACCESS_TOKEN",
        "registry.intsig.net/confluence-mcp/confluence-mcp:latest"
      ],
      "env": {
        "JIRA_URL": "https://your-company.atlassian.net",
        "CONFLUENCE_URL": "https://your-company.atlassian.net/wiki",
        "ATLASSIAN_OAUTH_CLOUD_ID": "YOUR_KNOWN_CLOUD_ID",
        "ATLASSIAN_OAUTH_ACCESS_TOKEN": "YOUR_PRE_EXISTING_OAUTH_ACCESS_TOKEN"
      }
    }
  }
}
```

> [!NOTE]
> - For the BYOT Method:
>   - You primarily need `JIRA_URL`, `CONFLUENCE_URL`, `ATLASSIAN_OAUTH_CLOUD_ID`, and `ATLASSIAN_OAUTH_ACCESS_TOKEN`.
>   - Standard OAuth client variables (`ATLASSIAN_OAUTH_CLIENT_ID`, `CLIENT_SECRET`, `REDIRECT_URI`, `SCOPE`) are **not** used.
>   - Token lifecycle (e.g., refreshing the token before it expires and restarting intsig-mcp-atlassian) is your responsibility, as the server will not refresh BYOT tokens.

</details>

<details>
<summary>Proxy Configuration</summary>

MCP Atlassian supports routing API requests through standard HTTP/HTTPS/SOCKS proxies. Configure using environment variables:

- Supports standard `HTTP_PROXY`, `HTTPS_PROXY`, `NO_PROXY`, `SOCKS_PROXY`.
- Service-specific overrides are available (e.g., `JIRA_HTTPS_PROXY`, `CONFLUENCE_NO_PROXY`).
- Service-specific variables override global ones for that service.

Add the relevant proxy variables to the `args` (using `-e`) and `env` sections of your MCP configuration:

```json
{
  "mcpServers": {
    "intsig-mcp-atlassian": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "... existing Confluence/Jira vars",
        "-e", "HTTP_PROXY",
        "-e", "HTTPS_PROXY",
        "-e", "NO_PROXY",
        "registry.intsig.net/confluence-mcp/confluence-mcp:latest"
      ],
      "env": {
        "... existing Confluence/Jira vars": "...",
        "HTTP_PROXY": "http://proxy.internal:8080",
        "HTTPS_PROXY": "http://proxy.internal:8080",
        "NO_PROXY": "localhost,.your-company.com"
      }
    }
  }
}
```

Credentials in proxy URLs are masked in logs. If you set `NO_PROXY`, it will be respected for requests to matching hosts.

</details>
<details>
<summary>Custom HTTP Headers Configuration</summary>

MCP Atlassian supports adding custom HTTP headers to all API requests. This feature is particularly useful in corporate environments where additional headers are required for security, authentication, or routing purposes.

Custom headers are configured using environment variables with comma-separated key=value pairs:

```json
{
  "mcpServers": {
    "intsig-mcp-atlassian": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "CONFLUENCE_URL",
        "-e", "CONFLUENCE_USERNAME",
        "-e", "CONFLUENCE_API_TOKEN",
        "-e", "CONFLUENCE_CUSTOM_HEADERS",
        "-e", "JIRA_URL",
        "-e", "JIRA_USERNAME",
        "-e", "JIRA_API_TOKEN",
        "-e", "JIRA_CUSTOM_HEADERS",
        "registry.intsig.net/confluence-mcp/confluence-mcp:latest"
      ],
      "env": {
        "CONFLUENCE_URL": "https://your-company.atlassian.net/wiki",
        "CONFLUENCE_USERNAME": "your.email@company.com",
        "CONFLUENCE_API_TOKEN": "your_confluence_api_token",
        "CONFLUENCE_CUSTOM_HEADERS": "X-Confluence-Service=mcp-integration,X-Custom-Auth=confluence-token,X-ALB-Token=secret-token",
        "JIRA_URL": "https://your-company.atlassian.net",
        "JIRA_USERNAME": "your.email@company.com",
        "JIRA_API_TOKEN": "your_jira_api_token",
        "JIRA_CUSTOM_HEADERS": "X-Forwarded-User=service-account,X-Company-Service=intsig-mcp-atlassian,X-Jira-Client=mcp-integration"
      }
    }
  }
}
```

**Security Considerations:**

- Custom header values are masked in debug logs to protect sensitive information
- Ensure custom headers don't conflict with standard HTTP or Atlassian API headers
- Avoid including sensitive authentication tokens in custom headers if already using basic auth or OAuth
- Headers are sent with every API request - verify they don't interfere with API functionality

</details>


<details>
<summary>Multi-Cloud OAuth Support</summary>

MCP Atlassian supports multi-cloud OAuth scenarios where each user connects to their own Atlassian cloud instance. This is useful for multi-tenant applications, chatbots, or services where users provide their own OAuth tokens.

**Minimal OAuth Configuration:**

1. Enable minimal OAuth mode (no client credentials required):
   ```bash
   docker run -e ATLASSIAN_OAUTH_ENABLE=true -p 9000:9000 \
     registry.intsig.net/confluence-mcp/confluence-mcp:latest \
     --transport streamable-http --port 9000
   ```

2. Users provide authentication via HTTP headers:
   - `Authorization: Bearer <user_oauth_token>`
   - `X-Atlassian-Cloud-Id: <user_cloud_id>`

**Example Integration (Python):**
```python
import asyncio
from mcp.client.streamable_http import streamablehttp_client
from mcp import ClientSession

user_token = "user-specific-oauth-token"
user_cloud_id = "user-specific-cloud-id"

async def main():
    # Connect to streamable HTTP server with custom headers
    async with streamablehttp_client(
        "http://localhost:9000/mcp",
        headers={
            "Authorization": f"Bearer {user_token}",
            "X-Atlassian-Cloud-Id": user_cloud_id
        }
    ) as (read_stream, write_stream, _):
        # Create a session using the client streams
        async with ClientSession(read_stream, write_stream) as session:
            # Initialize the connection
            await session.initialize()

            # Example: Get a Jira issue
            result = await session.call_tool(
                "jira_get_issue",
                {"issue_key": "PROJ-123"}
            )
            print(result)

asyncio.run(main())
```

**Configuration Notes:**
- Each request can use a different cloud instance via the `X-Atlassian-Cloud-Id` header
- User tokens are isolated per request - no cross-tenant data leakage
- Falls back to global `ATLASSIAN_OAUTH_CLOUD_ID` if header not provided
- Compatible with standard OAuth 2.0 bearer token authentication

### 👥 HTTP Transport Configuration

Instead of using `stdio`, you can run the server as a persistent HTTP service using either:
- `sse` (Server-Sent Events) transport at `/sse` endpoint
- `streamable-http` transport at `/mcp` endpoint

Both transport types support single-user and multi-user authentication:

**Authentication Options:**
- **Single-User**: Use server-level authentication configured via environment variables
- **Multi-User**: Each user provides their own authentication:
  - Cloud: OAuth 2.0 Bearer tokens
  - Server/Data Center: Personal Access Tokens (PATs)

<details> <summary>Basic HTTP Transport Setup</summary>

1. Start the server with your chosen transport:

    ```bash
    # For SSE transport
    docker run --rm -p 9000:9000 \
      --env-file /path/to/your/.env \
      registry.intsig.net/confluence-mcp/confluence-mcp:latest \
      --transport sse --port 9000 -vv

    # OR for streamable-http transport
    docker run --rm -p 9000:9000 \
      --env-file /path/to/your/.env \
      registry.intsig.net/confluence-mcp/confluence-mcp:latest \
      --transport streamable-http --port 9000 -vv
    ```

2. Configure your IDE (single-user example):

    **SSE Transport Example:**
    ```json
    {
      "mcpServers": {
        "intsig-mcp-atlassian-http": {
          "url": "http://localhost:9000/sse"
        }
      }
    }
    ```

    **Streamable-HTTP Transport Example:**
    ```json
    {
      "mcpServers": {
        "intsig-mcp-atlassian-service": {
          "url": "http://localhost:9000/mcp"
        }
      }
    }
    ```
</details>

<details> <summary>Multi-User Authentication Setup</summary>

Here's a complete example of setting up multi-user authentication with streamable-HTTP transport:

1. First, run the OAuth setup wizard to configure the server's OAuth credentials:
   ```bash
   docker run --rm -i \
     -p 8080:8080 \
     -v "${HOME}/.intsig-mcp-atlassian:/home/app/.intsig-mcp-atlassian" \
     registry.intsig.net/confluence-mcp/confluence-mcp:latest --oauth-setup -v
   ```

2. Start the server with streamable-HTTP transport:
   ```bash
   docker run --rm -p 9000:9000 \
     --env-file /path/to/your/.env \
     registry.intsig.net/confluence-mcp/confluence-mcp:latest \
     --transport streamable-http --port 9000 -vv
   ```

3. Configure your IDE's MCP settings:

**Choose the appropriate Authorization method for your Atlassian deployment:**

- **Cloud (OAuth 2.0):** Use this if your organization is on Atlassian Cloud and you have an OAuth access token for each user.
- **Server/Data Center (PAT):** Use this if you are on Atlassian Server or Data Center and each user has a Personal Access Token (PAT).

**Cloud (OAuth 2.0) Example:**
```json
{
  "mcpServers": {
    "intsig-mcp-atlassian-service": {
      "url": "http://localhost:9000/mcp",
      "headers": {
        "Authorization": "Bearer <USER_OAUTH_ACCESS_TOKEN>"
      }
    }
  }
}
```

**Server/Data Center (PAT) Example:**
```json
{
  "mcpServers": {
    "intsig-mcp-atlassian-service": {
      "url": "http://localhost:9000/mcp",
      "headers": {
        "Authorization": "Token <USER_PERSONAL_ACCESS_TOKEN>"
      }
    }
  }
}
```

4. Required environment variables in `.env`:
   ```bash
   JIRA_URL=https://your-company.atlassian.net
   CONFLUENCE_URL=https://your-company.atlassian.net/wiki
   ATLASSIAN_OAUTH_CLIENT_ID=your_oauth_app_client_id
   ATLASSIAN_OAUTH_CLIENT_SECRET=your_oauth_app_client_secret
   ATLASSIAN_OAUTH_REDIRECT_URI=http://localhost:8080/callback
   ATLASSIAN_OAUTH_SCOPE=read:jira-work write:jira-work read:confluence-content.all write:confluence-content offline_access
   ATLASSIAN_OAUTH_CLOUD_ID=your_cloud_id_from_setup_wizard
   ```

> [!NOTE]
> - The server should have its own fallback authentication configured (e.g., via environment variables for API token, PAT, or its own OAuth setup using --oauth-setup). This is used if a request doesn't include user-specific authentication.
> - **OAuth**: Each user needs their own OAuth access token from your Atlassian OAuth app.
> - **PAT**: Each user provides their own Personal Access Token.
> - **Multi-Cloud**: For OAuth users, optionally include `X-Atlassian-Cloud-Id` header to specify which Atlassian cloud instance to use
> - The server will use the user's token for API calls when provided, falling back to server auth if not
> - User tokens should have appropriate scopes for their needed operations

### Tool Filtering and Access Control

The server provides two ways to control tool access:

1. **Tool Filtering**: Use `--enabled-tools` flag or `ENABLED_TOOLS` environment variable to specify which tools should be available:

   ```bash
   # Via environment variable
   ENABLED_TOOLS="confluence_search,jira_get_issue,jira_search"

   # Or via command line flag
   docker run ... --enabled-tools "confluence_search,jira_get_issue,jira_search" ...
   ```

2. **Read/Write Control**: Tools are categorized as read or write operations. When `READ_ONLY_MODE` is enabled, only read operations are available regardless of `ENABLED_TOOLS` setting.

## Troubleshooting & Debugging

### Common Issues

- **Authentication Failures**:
    - For Cloud: Check your API tokens (not your account password)
    - For Server/Data Center: Verify your personal access token is valid and not expired
    - For older Confluence servers: Some older versions require basic authentication with `CONFLUENCE_USERNAME` and `CONFLUENCE_API_TOKEN` (where token is your password)
- **SSL Certificate Issues**: If using Server/Data Center and encounter SSL errors, set `CONFLUENCE_SSL_VERIFY=false` or `JIRA_SSL_VERIFY=false`
- **Permission Errors**: Ensure your Atlassian account has sufficient permissions to access the spaces/projects
- **Custom Headers Issues**: See the ["Debugging Custom Headers"](#debugging-custom-headers) section below to analyze and resolve issues with custom headers

### Debugging Custom Headers

To verify custom headers are being applied correctly:

1. **Enable Debug Logging**: Set `MCP_VERY_VERBOSE=true` to see detailed request logs
   ```bash
   # In your .env file or environment
   MCP_VERY_VERBOSE=true
   MCP_LOGGING_STDOUT=true
   ```

2. **Check Header Parsing**: Custom headers appear in logs with masked values for security:
   ```
   DEBUG Custom headers applied: {'X-Forwarded-User': '***', 'X-ALB-Token': '***'}
   ```

3. **Verify Service-Specific Headers**: Check logs to confirm the right headers are being used:
   ```
   DEBUG Jira request headers: service-specific headers applied
   DEBUG Confluence request headers: service-specific headers applied
   ```

4. **Test Header Format**: Ensure your header string format is correct:
   ```bash
   # Correct format
   JIRA_CUSTOM_HEADERS=X-Custom=value1,X-Other=value2
   CONFLUENCE_CUSTOM_HEADERS=X-Custom=value1,X-Other=value2

   # Incorrect formats (will be ignored)
   JIRA_CUSTOM_HEADERS="X-Custom=value1,X-Other=value2"  # Extra quotes
   JIRA_CUSTOM_HEADERS=X-Custom: value1,X-Other: value2  # Colon instead of equals
   JIRA_CUSTOM_HEADERS=X-Custom = value1               # Spaces around equals
   ```

**Security Note**: Header values containing sensitive information (tokens, passwords) are automatically masked in logs to prevent accidental exposure.

### Debugging Tools

```bash
# Using MCP Inspector for testing
npx @modelcontextprotocol/inspector uvx intsig-mcp-atlassian ...

# For local development version
npx @modelcontextprotocol/inspector uv --directory /path/to/your/intsig-mcp-atlassian run intsig-mcp-atlassian ...

# View logs
# macOS
tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
# Windows
type %APPDATA%\Claude\logs\mcp*.log | more
```

## Security

- Never share API tokens
- Keep .env files secure and private
