> [!TIP]
> This will automatically discover and connect to any MCP servers configured in Claude's settings and use the default model `qwen2.5:7b` or the model specified in your configuration file.

Connect to a single server:

```bash
ollmcp --mcp-server /path/to/weather.py --model llama3.2:3b
# Or using short flags:
ollmcp -s /path/to/weather.py -m llama3.2:3b
```

Connect to multiple servers:

```bash
ollmcp --mcp-server /path/to/weather.py --mcp-server /path/to/filesystem.js
# Or using short flags:
ollmcp -s /path/to/weather.py -s /path/to/filesystem.js
```

>[!TIP]
> If model is not specified, the default model `qwen2.5:7b` will be used or the model specified in your configuration file.

Use a JSON configuration file:

```bash
ollmcp --servers-json /path/to/servers.json --model llama3.2:1b
# Or using short flags:
ollmcp -j /path/to/servers.json -m llama3.2:1b
```

>[!TIP]
> See the [Server Configuration Format](#server-configuration-format) section for details on how to structure the JSON file.

Use a custom Ollama host:

```bash
ollmcp --host http://localhost:22545 --servers-json /path/to/servers.json --auto-discovery
# Or using short flags:
ollmcp -H http://localhost:22545 -j /path/to/servers.json -a
```

Connect to SSE or Streamable HTTP servers by URL:

```bash
ollmcp --mcp-server-url http://localhost:8000/sse --model qwen2.5:latest
# Or using short flags:
ollmcp -u http://localhost:8000/sse -m qwen2.5:latest
```

Connect to multiple URL servers:

> [!TIP]
> All parameters default to unset, letting Ollama use its own optimized values. Use `help` in the config menu for details and recommendations. Changes are saved with your configuration.


### Server Reloading for Development

The `reload-servers` command (`rs`) is particularly useful during MCP server development. It allows you to reload all connected servers without restarting the entire client application.

**Key Benefits:**
- 🔄 **Hot Reload**: Instantly apply changes to your MCP server code
- 🛠️ **Development Workflow**: Perfect for iterative development and testing
- 📝 **Configuration Updates**: Automatically picks up changes in server JSON configs or Claude configs
- 🎯 **State Preservation**: Maintains your tool enabled/disabled preferences across reloads
- ⚡️ **Time Saving**: No need to restart the client and reconfigure everything

**When to Use:**
- After modifying your MCP server implementation
- When you've updated server configurations in JSON files
- After changing Claude's MCP configuration
- During debugging to ensure you're testing the latest server version

Simply type `reload-servers` or `rs` in the chat interface, and the client will:
1. Disconnect from all current MCP servers
2. Reconnect using the same parameters (server paths, config files, auto-discovery)
3. Restore your previous tool enabled/disabled settings
4. Display the updated server and tool status

This feature dramatically improves the development experience when building and testing MCP servers.

### Human-in-the-Loop (HIL) Tool Execution

The Human-in-the-Loop feature provides an additional safety layer by allowing you to review and approve tool executions before they run. This is particularly useful for:

- 🛡️ **Safety**: Review potentially destructive operations before execution
- 🔍 **Learning**: Understand what tools the model wants to use and why
- 🎯 **Control**: Selective execution of only the tools you approve
- 🚫 **Prevention**: Stop unwanted tool calls from executing
- 🔄 **Session Mode**: Auto-approve all tools for the current query session
- 🛑 **Query Abort**: Abort entire query without saving to history

#### HIL Confirmation Display

When HIL is enabled, you'll see a confirmation prompt before each tool execution:

**Example:**

![ollmcp HIL confirmation screenshot](https://github.com/jonigl/mcp-client-for-ollama/blob/main/misc/ollmcp-hil-feature.png?raw=true)

#### HIL Confirmation Options

When prompted, you can choose from the following options:

- **y/yes**: Execute this specific tool call
- **n/no**: Skip this tool call and continue with the query
- **s/session**: Execute this and all subsequent tool calls for the current query without further prompts
- **d/disable**: Permanently disable HIL confirmations (can be re-enabled with `hil` command)
- **a/abort**: Abort the entire query immediately without saving to history

> [!TIP]
> The **session** option is particularly useful when the model needs to execute multiple tools in sequence. Instead of confirming each one individually, you can approve all tools for the current query session, then HIL will reset automatically for the next query.

### Human-in-the-Loop (HIL) Configuration

- **Default State**: HIL confirmations are enabled by default for safety
- **Toggle Command**: Use `human-in-loop` or `hil` to toggle on/off
- **Persistent Settings**: HIL preference is saved with your configuration
- **Quick Disable**: Choose "disable" during any confirmation to turn off permanently
- **Session Auto-Approve**: Use "session" during confirmation to approve all tools for current query
- **Query Abort**: Use "abort" during confirmation to immediately stop the query without saving
- **Re-enable**: Use the `hil` command anytime to turn confirmations back on

**Benefits:**
- **Enhanced Safety**: Prevent accidental or unwanted tool executions
- **Awareness**: Understand what actions the model is attempting to perform
- **Selective Control**: Choose which operations to allow on a case-by-case basis
- **Flexible Workflow**: Session mode for efficient multi-tool queries, individual approval for sensitive operations
- **Clean Abort**: Stop problematic queries immediately without polluting conversation history
- **Peace of Mind**: Full visibility and control over automated actions

### MCP Prompts

MCP Prompts provide reusable, server-defined conversation starters and context templates. Servers can expose prompts with descriptions, required arguments, and pre-formatted messages that help you quickly start specific types of conversations or inject structured context into your chat.

#### Features

- 📋 **Browse Prompts**: View all available prompts from connected servers with descriptions and argument requirements
- ⚡️ **Quick Invocation**: Use `/prompt_name` syntax to instantly invoke any prompt
- 🔤 **Autocomplete**: Type `/` to see prompt suggestions with fuzzy matching
- 📝 **Argument Collection**: Interactive prompts guide you through required parameters
- 👁️ **Preview**: Review prompt content before injection to ensure it fits your needs
- 🎯 **Flexible Injection**: Choose to execute immediately or inject-only (add to history without triggering model)
- 🧠 **Context-Aware**: Automatically adapts behavior based on whether prompt ends with user or assistant message
- 🔄 **Safe Rollback**: Automatic history cleanup if you abort or encounter errors
- 💬 **Text Content**: Supports text-based prompt messages (image/audio/resource support coming soon)

#### How to Use MCP Prompts

**Browse Available Prompts:**
```
prompts  # or 'pr'
```
This displays all prompts grouped by server, showing their names, required arguments, and descriptions.

**Invoke a Prompt:**
```
/prompt_name
```
For example, if a server provides a "summarize" prompt:
```
/summarize
```

**Autocomplete:**
- Type `/` to see all available prompts with descriptions
- Continue typing to filter prompts with fuzzy matching
- Use arrow keys to navigate and press Enter to select

> [!TIP]
> Prompts are discovered automatically when you connect to MCP servers. If a server supports prompts, they'll be available immediately in the `prompts` list and autocomplete.

**Workflow:**
1. Type `/prompt_name` or select from autocomplete
2. If the prompt requires arguments, you'll be prompted to provide them
3. Review the prompt preview showing what will be injected
4. Choose how to use the prompt:
   - **y/yes** (default): Send the prompt to the model and get a response
     - For prompts ending with a **user message**: Uses that message as the query
     - For prompts ending with an **assistant message**: Adds "Please respond based on the above context." as the query
   - **i/inject**: Just add the prompt to conversation history without triggering the model (lets you type your own query afterward)
   - **n/no**: Cancel and return to chat
5. The prompt is injected based on your choice
6. If you abort during model generation (press 'a'), changes are automatically rolled back

**Example:**
![ollmcp prompt feature screenshot](https://github.com/jonigl/mcp-client-for-ollama/blob/main/misc/ollmcp-prompt-feature.png?raw=true)

> [!WARNING]
> **Content Type Limitations**: MCP Prompts currently support **text content only**. The following content types are not yet supported and will be automatically skipped:
> - 🖼️ **Images** - Image content in prompts
> - 🎵 **Audio** - Audio content in prompts
> - 📦 **Resources** - Embedded resource content
>
> If a prompt contains these unsupported types, you'll see a warning during the preview, and only the text portions will be injected. Make sure your prompt still makes sense without the multimedia content before proceeding. Full multimedia support is planned for a future release.


### Performance Metrics

The Performance Metrics feature displays detailed model performance data after each query in a bordered panel. The metrics show duration timings, token counts, and generation rates directly from Ollama's response.

**Displayed Metrics:**
- `total duration`: Total time spent generating the complete response (seconds)
- `load duration`: Time spent loading the model (milliseconds)
- `prompt eval count`: Number of tokens in the input prompt
- `prompt eval duration`: Time spent evaluating the input prompt (milliseconds)
- `eval count`: Number of tokens generated in the response
- `eval duration`: Time spent generating the response tokens (seconds)
- `prompt eval rate`: Speed of input prompt processing (tokens/second)
- `eval rate`: Speed of response token generation (tokens/second)

**Example:**
![ollmcp ollama performance metrics screenshot](https://github.com/jonigl/mcp-client-for-ollama/blob/main/misc/ollmcp-ollama-performance-metrics.png?raw=true)

#### Performance Metrics Configuration

- **Default State**: Metrics are disabled by default for cleaner output
- **Toggle Command**: Use `show-metrics` or `sm` to enable/disable metrics display
- **Persistent Settings**: Metrics preference is saved with your configuration

**Benefits:**
- **Performance Monitoring**: Track model efficiency and response times
- **Token Tracking**: Monitor actual token consumption for analysis
- **Benchmarking**: Compare performance across different models

> [!NOTE]
> **Data Source**: All metrics come directly from Ollama's response, ensuring accuracy and reliability.

### History Management

The History Management feature allows you to view, export, and import your conversation history. This is useful for:

- 📜 **Full History View**: Review all conversations from your current session
- 💾 **Export**: Save conversations to JSON files for backup or analysis
- 📥 **Import**: Load previous conversation history to continue where you left off
- 🔄 **Portability**: Share or transfer conversations between sessions

#### History Commands

**View Full History:**
```
full-history  # or 'fh'
```
Displays all conversation history from the current session in a formatted view, showing both queries and responses.

**Export History:**
```
export-history  # or 'eh'
```
Exports your current chat history to a JSON file. You can specify a custom filename or use the default timestamp-based name (e.g., `ollmcp_chat_history_2026-01-05_143022.json`). Files are saved to `~/.config/ollmcp/history/` directory. The command includes file overwrite protection.

**Import History:**
```
import-history  # or 'ih'
```
Imports a previously exported chat history from a JSON file. The command validates the JSON structure to ensure compatibility. Imported history is added to your current conversation context.

**History Storage:**
- Export location: `~/.config/ollmcp/history/`
- Default filename format: `ollmcp_chat_history_YYYY-MM-DD_HHMMSS.json`
- JSON format includes both queries and responses with proper structure validation

**Benefits:**
- **Session Continuity**: Resume conversations across different sessions
- **Backup**: Keep records of important conversations
- **Analysis**: Export history for external analysis or review
- **Sharing**: Share conversation context with team members
- **Testing**: Import test conversations for development and debugging

> [!TIP]
> When exporting, if you don't provide a filename, the system automatically generates a timestamped filename to prevent accidental overwrites.

## Autocomplete and Prompt Features

### Typer Shell Autocompletion

- The CLI supports shell autocompletion for all options and arguments via Typer
- To enable, run `ollmcp --install-completion` and follow the instructions for your shell
- Enjoy tab-completion for all grouped and general options

### FZF-style Autocomplete

- Fuzzy matching for commands as you type
- Arrow (`▶`) highlights the best match
- Command descriptions shown in the menu
- Case-insensitive matching for convenience
- Centralized command list for consistency

### MCP Prompts Autocomplete

- Type `/` to trigger prompt autocomplete
- Fuzzy matching on prompt names and descriptions
- Shows prompt arguments and descriptions in the menu
- Terminal-width-aware description truncation
- Arrow (`▶`) highlights the best match

### Contextual Prompt

The chat prompt now gives you clear, contextual information at a glance:

- **Model**: Shows the current Ollama model in use
- **Thinking Mode**: Indicates if "thinking mode" is active (for supported models)
- **Tools**: Displays the number of enabled tools

**Example prompt:**
```
qwen3/show-thinking/12-tools❯
```
- `qwen3` Model name
- `/show-thinking` Thinking mode indicator (if enabled, otherwise `/thinking` or omitted)
- `/12-tools` Number of tools enabled (or `/1-tool` for singular)
- `❯` Prompt symbol

This makes it easy to see your current context before entering a query.

> [!TIP]
> Type `/` after the prompt symbol to see autocomplete suggestions for available MCP prompts.

## Configuration Management

> [!TIP]
> It will automatically load the default configuration from `~/.config/ollmcp/config.json` if it exists.

The client supports saving and loading tool configurations between sessions:

- When using `save-config`, you can provide a name for the configuration or use the default
- Configurations are stored in `~/.config/ollmcp/` directory
- The default configuration is saved as `~/.config/ollmcp/config.json`
- Named configurations are saved as `~/.config/ollmcp/{name}.json`

The configuration saves:

- Current model selection
- Advanced model parameters (system prompt, temperature, sampling settings, etc.)
- Enabled/disabled status of all tools
- Context retention settings
- Thinking mode settings
- Tool execution display preferences
- Performance metrics display preferences
- Human-in-the-Loop confirmation settings

## Server Configuration Format

The JSON configuration file supports STDIO, SSE, and Streamable HTTP server types (MCP 1.10.1):

```json
{
  "mcpServers": {
    "stdio-server": {
      "command": "command-to-run",
      "args": ["arg1", "arg2", "..."],
      "env": {
        "ENV_VAR1": "value1",
        "ENV_VAR2": "value2"
      },
      "disabled": false
    },
    "sse-server": {
      "type": "sse",
      "url": "http://localhost:8000/sse",
      "headers": {
        "Authorization": "Bearer your-token-here"
      },
      "disabled": false
    },
    "http-server": {
      "type": "streamable_http",
      "url": "http://localhost:8000/mcp",
      "headers": {
        "X-API-Key": "your-api-key-here"
      },
      "disabled": false
    }
  }
}
```
> [!NOTE]
> **MCP 1.10.1 Transport Support**: The client now supports the latest Streamable HTTP transport with improved performance and reliability. If you specify a URL without a type, the client will default to using Streamable HTTP transport.

### Tips: where to put MCP server configs and a working example

A common point of confusion is where to store MCP server configuration files and how the TUI's save/load feature is used. Here's a short, practical guide that has helped other users:

- The TUI's `save-config` / `load-config` (or `sc` / `lc`) commands are intended to save *TUI preferences* like which tools you enabled, your selected model, thinking mode, and other client-side settings. They are not required to register MCP server connections with the client.
- For MCP server JSON files (the `mcpServers` object shown above) we recommend keeping them outside the TUI config directory or in a clear subfolder, for example:

```
~/.config/ollmcp/mcp-servers/config.json
```

You can then point `ollmcp` at that file at startup with `-j` / `--servers-json`.

> [!IMPORTANT]
> When using HTTP-based MCP servers, use the `streamable_http` type (not just `http`). Also check the [Common MCP endpoint paths](#common-mcp-endpoint-paths) section below for typical endpoints.

Here a minimal working example let's say this is your `~/.config/ollmcp/mcp-servers/config.json`:

```json
{
  "mcpServers": {
    "github": {
      "type": "streamable_http",
      "url": "https://api.githubcopilot.com/mcp/",
      "headers": {
        "Authorization": "Bearer mytoken"
      }
    }
  }
}
```

> [!TIP]
> When using GitHub MCP server, make sure to replace `"mytoken"` with your actual GitHub API token.

With that file in place you can connect using:

```
ollmcp -j ~/.config/ollmcp/mcp-servers/config.json
```

Here you can find a GitHub issue related to this common pitfall: https://github.com/jonigl/mcp-client-for-ollama/issues/112#issuecomment-3446569030

#### Demo

A short demo (asciicast) that should help anyone reproduce the working setup quickly. This example uses an [MCP server example with streamable HTTP protocol](https://github.com/jonigl/mcp-server-with-streamable-http-example) usage:

[![asciicast](https://asciinema.org/a/751387.svg)](https://asciinema.org/a/751387)

#### Common MCP endpoint paths

Streamable HTTP MCP servers typically expose the MCP endpoint at `/mcp` (e.g., `https://host/mcp`), while SSE servers commonly use `/sse` (e.g., `https://host/sse`). Below is an excerpt from the MCP specification (2025-06-18):
> The server MUST provide a single HTTP endpoint path (hereafter referred to as the MCP endpoint) that supports both POST and GET methods. For example, this could be a URL like https://example.com/mcp.

You can find more details in the [MCP specification version 2025-06-18 - Transports](https://modelcontextprotocol.io/specification/2025-06-18/basic/transports).

## Compatible Models

The following Ollama models work well with tool use:

- qwen2.5
- qwen3
- llama3.1
- llama3.2
- mistral

### Ollama Cloud Models

MCP Client for Ollama now supports [Ollama Cloud models](https://github.com/ollama/ollama/blob/main/docs/cloud.md), allowing you to use powerful cloud-hosted models with tool calling capabilities while leveraging your local MCP tools. Cloud models can run without a powerful local GPU, making it possible to access larger models that wouldn't fit on a personal computer.

**Supported Ollama Cloud models include for example:**
- `gpt-oss:20b-cloud`
- `gpt-oss:120b-cloud`
- `deepseek-v3.1:671b-cloud`
- `qwen3-coder:480b-cloud`

**To use Ollama Cloud models with this client:**

1. First, pull the cloud model:
   ```bash
   ollama pull gpt-oss:120b-cloud
   ```

2. Run the client with your chosen cloud model:
   ```bash
   ollmcp --model gpt-oss:120b-cloud
   ```

> [!NOTE]
> The model `deepseek-v3.1:671b-cloud` only supports tool use when thinking mode is turned off. You can toggle thinking mode in `ollmcp` by typing either `thinking-mode` or `tm`.

For more information about Ollama Cloud, visit the [Ollama Cloud documentation](https://docs.ollama.com/cloud).

### How Tool Calls Work

1. The client sends your query to Ollama with a list of available tools
2. If Ollama decides to use a tool, the client:
   - Displays the tool execution with formatted arguments and syntax highlighting
   - Shows a Human-in-the-Loop confirmation prompt (if enabled) allowing you to review and approve the tool call
   - Extracts the tool name and arguments from the model response
   - Calls the appropriate MCP server with these arguments (only if approved or HIL is disabled)
   - Shows the tool response in a structured, easy-to-read format
   - Sends the tool result back to Ollama
   - If in Agent Mode, repeats the process if the model requests more tool calls
3. Finally, the client:
   - Displays the model's final response incorporating the tool results

### Agent Mode

Some models may request multiple tool calls in a single conversation. The client supports an **Agent Mode** that allows for iterative tool execution:
- When the model requests a tool call, the client executes it and sends the result back to the model
- This process repeats until the model provides a final answer or reaches the configured loop limit
- You can set the maximum number of iterations using the `loop-limit` (`ll`) command
- The default loop limit is `3` to prevent infinite loops

> [!NOTE]
> If you want to prevent using Agent Mode, simply set the loop limit to `1`.
