**mcp-name: io.github.jztan/redmine-mcp-server**

## [Tool reference](./docs/tool-reference.md) | [Changelog](./CHANGELOG.md) | [Contributing](./docs/contributing.md) | [Troubleshooting](./docs/troubleshooting.md)

## Features

- **Redmine Integration**: List projects, view/create/update issues, download attachments
- **HTTP File Serving**: Secure file access via UUID-based URLs with automatic expiry
- **MCP Compliant**: Full Model Context Protocol support with FastMCP and streamable HTTP transport
- **Flexible Authentication**: Username/password or API key
- **File Management**: Automatic cleanup of expired files with storage statistics
- **Docker Ready**: Complete containerization support
- **Pagination Support**: Efficiently handle large issue lists with configurable limits

## Quick Start

1. **Install the package**
   ```bash
   pip install redmine-mcp-server
   ```
2. **Create a `.env` file** with your Redmine credentials (see [Installation](#installation) for template)
3. **Start the server**
   ```bash
   redmine-mcp-server
   ```
4. **Add the server to your MCP client** using one of the guides in [MCP Client Configuration](#mcp-client-configuration).

Once running, the server listens on `http://localhost:8000` with the MCP endpoint at `/mcp`, health check at `/health`, and file serving at `/files/{file_id}`.

## Installation

### Prerequisites

- Python 3.10+ (for local installation)
- Docker (alternative deployment, uses Python 3.13)
- Access to a Redmine instance

### Install from PyPI (Recommended)

```bash
# Install the package
pip install redmine-mcp-server

# Create configuration file .env
cat > .env << 'EOF'
# Redmine connection (required)
REDMINE_URL=https://your-redmine-server.com

# Authentication - Use either API key (recommended) or username/password
REDMINE_API_KEY=your_api_key
# OR use username/password:
# REDMINE_USERNAME=your_username
# REDMINE_PASSWORD=your_password

# Server configuration (optional, defaults shown)
SERVER_HOST=0.0.0.0
SERVER_PORT=8000

# Public URL for file serving (optional)
PUBLIC_HOST=localhost
PUBLIC_PORT=8000

# File management (optional)
ATTACHMENTS_DIR=./attachments
AUTO_CLEANUP_ENABLED=true
CLEANUP_INTERVAL_MINUTES=10
ATTACHMENT_EXPIRES_MINUTES=60
EOF

# Edit .env with your actual Redmine settings
nano .env  # or use your preferred editor

# Run the server
redmine-mcp-server
# Or alternatively:
python -m redmine_mcp_server.main
```

The server runs on `http://localhost:8000` with the MCP endpoint at `/mcp`, health check at `/health`, and file serving at `/files/{file_id}`.

### SSL Certificate Configuration

Configure SSL certificate handling for Redmine servers with self-signed certificates or internal CA infrastructure.

<details>
<summary><strong>Self-Signed Certificates</strong></summary>

If your Redmine server uses a self-signed certificate or internal CA:

```bash
# In .env file
REDMINE_URL=https://redmine.company.com
REDMINE_API_KEY=your_api_key
REDMINE_SSL_CERT=/path/to/ca-certificate.crt
```

Supported certificate formats: `.pem`, `.crt`, `.cer`

</details>

<details>
<summary><strong>Mutual TLS (Client Certificates)</strong></summary>

For environments requiring client certificate authentication:

```bash
# In .env file
REDMINE_URL=https://secure.redmine.com
REDMINE_API_KEY=your_api_key
REDMINE_SSL_CERT=/path/to/ca-bundle.pem
REDMINE_SSL_CLIENT_CERT=/path/to/cert.pem,/path/to/key.pem
```

**Note**: Private keys must be unencrypted (Python requests library requirement).

</details>

<details>
<summary><strong>Disable SSL Verification (Development Only)</strong></summary>

⚠️ **WARNING**: Only use in development/testing environments!

```bash
# In .env file
REDMINE_SSL_VERIFY=false
```

Disabling SSL verification makes your connection vulnerable to man-in-the-middle attacks.

</details>

For SSL troubleshooting, see the [Troubleshooting Guide](./docs/troubleshooting.md#ssl-certificate-errors).

## MCP Client Configuration

The server exposes an HTTP endpoint at `http://127.0.0.1:8000/mcp`. Register it with your preferred MCP-compatible agent using the instructions below.

<details>
<summary><strong>Visual Studio Code (Native MCP Support)</strong></summary>

VS Code has built-in MCP support via GitHub Copilot (requires VS Code 1.102+).

**Using CLI (Quickest):**
```bash
code --add-mcp '{"name":"redmine","type":"http","url":"http://127.0.0.1:8000/mcp"}'
```

**Using Command Palette:**
1. Open Command Palette (`Cmd/Ctrl+Shift+P`)
2. Run `MCP: Open User Configuration` (for global) or `MCP: Open Workspace Folder Configuration` (for project-specific)
3. Add the configuration:
   ```json
   {
     "servers": {
       "redmine": {
         "type": "http",
         "url": "http://127.0.0.1:8000/mcp"
       }
     }
   }
   ```
4. Save the file. VS Code will automatically load the MCP server.

**Manual Configuration:**
Create `.vscode/mcp.json` in your workspace (or `mcp.json` in your user profile directory):
```json
{
  "servers": {
    "redmine": {
      "type": "http",
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}
```

</details>

<details>
<summary><strong>Claude Code</strong></summary>

Add to Claude Code using the CLI command:

```bash
claude mcp add --transport http redmine http://127.0.0.1:8000/mcp
```

Or configure manually in your Claude Code settings file (`~/.claude.json`):

```json
{
  "mcpServers": {
    "redmine": {
      "type": "http",
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}
```

</details>

<details>
<summary><strong>Codex CLI</strong></summary>

Add to Codex CLI using the command:

```bash
codex mcp add redmine -- npx -y mcp-client-http http://127.0.0.1:8000/mcp
```

Or configure manually in `~/.codex/config.toml`:

```toml
[mcp_servers.redmine]
command = "npx"
args = ["-y", "mcp-client-http", "http://127.0.0.1:8000/mcp"]
```

**Note:** Codex CLI primarily supports stdio-based MCP servers. The above uses `mcp-client-http` as a bridge for HTTP transport.

</details>

<details>
<summary><strong>Kiro</strong></summary>

Kiro primarily supports stdio-based MCP servers. For HTTP servers, use an HTTP-to-stdio bridge:

1. Create or edit `.kiro/settings/mcp.json` in your workspace:
   ```json
   {
     "mcpServers": {
       "redmine": {
         "command": "npx",
         "args": [
           "-y",
           "mcp-client-http",
           "http://127.0.0.1:8000/mcp"
         ],
         "disabled": false
       }
     }
   }
   ```
2. Save the file and restart Kiro. The Redmine tools will appear in the MCP panel.

**Note:** Direct HTTP transport support in Kiro is limited. The above configuration uses `mcp-client-http` as a bridge to connect to HTTP MCP servers.

</details>

<details>
<summary><strong>Generic MCP Clients</strong></summary>

Most MCP clients use a standard configuration format. For HTTP servers:

```json
{
  "mcpServers": {
    "redmine": {
      "type": "http",
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}
```

For clients that require a command-based approach with HTTP bridge:

```json
{
  "mcpServers": {
    "redmine": {
      "command": "npx",
      "args": ["-y", "mcp-client-http", "http://127.0.0.1:8000/mcp"]
    }
  }
}
```

</details>

### Testing Your Setup

```bash
# Test connection by checking health endpoint
curl http://localhost:8000/health
```
