Docmost MCP Server

An MCP server that gives AI assistants direct access to your self-hosted Docmost documentation via its API.

Works with any MCP-compatible client, including:

Features

| Tool | Description | |------|-------------| | list_spaces | List all available documentation spaces with names, slugs, and IDs | | search_docs | Full-text search across all documentation, with optional space filtering | | get_page | Retrieve full page content converted from ProseMirror JSON to Markdown |

Prerequisites

Python 3.10+
A running Docmost instance with valid user credentials
An MCP-compatible client (Claude Code, Claude Desktop, Cursor, VS Code, etc.)

Installation

1. Clone the repository

git clone https://github.com/aleksvin8888/local-docmost-mcp.git
cd docmost-mcp

2. Create a virtual environment and install dependencies

python3 -m venv venv
source venv/bin/activate   # Linux / macOS
# venv\Scripts\activate    # Windows

pip install -r requirements.txt

This installs two dependencies:

mcp — official Python SDK for building MCP servers
requests — HTTP client for Docmost API calls

3. Configure credentials

Copy the example config and fill in your details:

cp config.example.json config.json

Edit config.json:

{
  "base_url": "https://your-docmost-instance.example.com",
  "email": "your-email@example.com",
  "password": "your-password",
  "timeout": 30
}

| Parameter | Description | |-----------|-------------| | base_url | URL of your Docmost instance (no trailing slash) | | email | Email address for Docmost authentication | | password | Password for Docmost authentication | | timeout | HTTP request timeout in seconds |

Note: config.json contains sensitive credentials and is excluded from version control via .gitignore.

4. Verify the setup

source venv/bin/activate   # if not already active

python docmost_client.py

Expected output:

=== Spaces ===
  My Space (my-space) - 019a2a69-...
  Another Space (another) - 019a5e21-...
  ...

=== Search 'example' ===
  Example Page Title - abc123def
  ...

If you see your spaces and search results, the client is working correctly.

Connecting to an MCP client

The server uses stdio transport, which is supported by all major MCP clients. Below are setup instructions for the most popular ones.

Claude Code

Choose one of the following options.

Important: Use absolute paths to both the Python binary inside venv and mcp_server.py.

Option 1: Global config (recommended)

Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "docmost": {
      "command": "/absolute/path/to/docmost-mcp/venv/bin/python",
      "args": ["/absolute/path/to/docmost-mcp/mcp_server.py"]
    }
  }
}

Option 2: Project-level config

Create .claude/settings.json in your project root:

{
  "mcpServers": {
    "docmost": {
      "command": "/absolute/path/to/docmost-mcp/venv/bin/python",
      "args": ["/absolute/path/to/docmost-mcp/mcp_server.py"]
    }
  }
}

Option 3: CLI command

claude mcp add docmost \
  -c "/absolute/path/to/docmost-mcp/venv/bin/python" \
  -- /absolute/path/to/docmost-mcp/mcp_server.py

After adding the config, restart Claude Code or start a new session.

Claude Desktop

Add the server to your Claude Desktop config file:

Linux: ~/.config/claude/claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "docmost": {
      "command": "/absolute/path/to/docmost-mcp/venv/bin/python",
      "args": ["/absolute/path/to/docmost-mcp/mcp_server.py"]
    }
  }
}

Restart Claude Desktop after saving the config.

Cursor / Windsurf / VS Code / Other clients

Most MCP clients use the same configuration format. Add the server with:

Command: /absolute/path/to/docmost-mcp/venv/bin/python
Args: /absolute/path/to/docmost-mcp/mcp_server.py
Transport: stdio

Refer to your client's documentation for the exact config file location and format.

Usage

Once the MCP server is connected, your AI assistant can use the following tools:

List all spaces

Show me all available documentation spaces

Search documentation

Search the documentation for "user permissions"

Search within a specific space

Find "API endpoints" in the Engineering space

Get a specific page

Show me the full content of page with slug_id "abc123def"

How it works

The MCP client launches the server as a subprocess and communicates via stdio (stdin/stdout).
On the first API call, the server authenticates with your Docmost instance using email/password and receives a JWT token from the Set-Cookie header.
The token is cached in token.json for subsequent requests. If a request returns 401, the server automatically re-authenticates and retries.
Page content is stored in Docmost as ProseMirror JSON. The server converts it to clean Markdown (headings, lists, tables, code blocks, images, links, etc.) before returning it to the client.

Project structure

docmost-mcp/
├── mcp_server.py         # MCP server (3 tools)
├── docmost_client.py     # Docmost API client
├── requirements.txt      # Python dependencies (mcp, requests)
├── config.example.json   # Configuration template

├── token.json            # Cached JWT token (auto-generated, not in git)

└── README.md

Security

config.json contains your credentials — never commit it to git
token.json contains a JWT token — never commit it to git
Both files are already listed in .gitignore

Troubleshooting

"No authToken in response cookies"

Verify that email and password in config.json are correct
Verify that base_url points to your Docmost instance

"Connection refused"

Check that your Docmost instance is running and accessible
Check your network connection and firewall rules

"401 Unauthorized"

The token may have expired — delete token.json and it will be recreated automatically on the next request

MCP tools not appearing in the client

Ensure you used absolute paths to venv/bin/python and mcp_server.py
Check that the virtual environment has all dependencies installed (pip install -r requirements.txt)
Restart your MCP client after changing the config
