Paperless MCP Server

How to use

Connect your MCP client to your Paperless MCP Server using either the HTTP transport or the stdio transport. With HTTP, your server acts as a standalone service that the client can reach over the network. With stdio, the MCP server runs locally alongside the client process, communicating through standard input and output. You can perform common document operations such as searching, retrieving content, creating or updating documents, and managing related metadata like correspondents, document types, tags, and custom fields. Security can be enhanced by enabling an MCP authentication token when exposing HTTP.

How to install

Prerequisites you need before installing the MCP server:

• A running Paperless-ngx instance
• Paperless-ngx API token
• Docker and Docker Compose (optional for containerized deployment)

Choose your preferred deployment method. The MCP server provides both HTTP transport and stdio transport options. Follow the steps below for each method.

PAPERLESS_URL=https://paperless.example.com
PAPERLESS_TOKEN=your_paperless_api_token_here
MCP_TRANSPORT=http
MCP_HTTP_PORT=8080
```
```bash
# Run via Docker for HTTP transport
docker run --rm --env-file .env -p 8080:8080  cbinckly/paperless-mcp-go:latest

HTTP transport setup

To run the MCP server as a standalone HTTP service, configure the environment and start the server. You will access the MCP endpoint at the provided port.

Example start command and URL:

export PAPERLESS_URL=https://paperless.example.com
export PAPERLESS_TOKEN=your_token_here
export MCP_TRANSPORT=http
export MCP_HTTP_PORT=8080

./paperless-mcp
# Then open http://localhost:8080/mcp

Stdio transport setup

To run the MCP server locally with stdio transport, use a local process that launches the MCP server and communicates via standard IO streams.

Example container-based stdio setup using Docker (as shown in the configuration example):

{
  "mcpServers": {
    "paperless_mcp": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "--pull=always",
        "cbinckly/paperless-mcp-go:latest"
      ],
      "env": {
        "PAPERLESS_URL": "https://paperless.example.com",
        "PAPERLESS_TOKEN": "your_paperless_api_token_here",
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

Security and access control

You can enable an optional authentication token for MCP clients when using HTTP transport. Set MCP_AUTH_TOKEN in the environment; clients must present it as a Bearer token in the Authorization header to access MCP endpoints. This helps protect your Paperless data from unauthorized access.
