A Model Context Protocol server for interacting with Outline document management.

## Features

- **Document operations**: Search, read, create, edit, archive documents
- **Collections**: List, create, manage document hierarchies
- **Comments**: Add and view threaded comments
- **Backlinks**: Find documents referencing a specific document
- **MCP Resources**: Direct content access via URIs (outline://document/{id}, outline://collection/{id}, etc.)
- **Automatic rate limiting**: Transparent handling of API limits with retry logic

## Prerequisites

Before using this MCP server, you need:

- An [Outline](https://www.getoutline.com/) account (cloud hosted or self-hosted)
- API key from Outline web UI: **Settings → API Keys → Create New**
- Python 3.10+ (for non-Docker installations)

> **Getting your API key**: Log into Outline → Click your profile → Settings → API Keys → "New API Key". Copy the generated token.

## Installation

### Using uv (Recommended)

```bash
uvx mcp-outline
```

### Using pip

```bash
pip install mcp-outline
```

### Using Docker

```bash
docker run -e OUTLINE_API_KEY=<your-key> ghcr.io/vortiago/mcp-outline:latest
```

Or build from source:
```bash
docker buildx build -t mcp-outline .
docker run -e OUTLINE_API_KEY=<your-key> mcp-outline
```

## Configuration

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `OUTLINE_API_KEY` | Yes | - | Get from Outline web UI: Settings → API Keys → Create New |
| `OUTLINE_API_URL` | No | `https://app.getoutline.com/api` | For self-hosted: `https://your-domain/api` |
| `OUTLINE_READ_ONLY` | No | `false` | `true` = disable ALL write operations ([details](#read-only-mode)) |
| `OUTLINE_DISABLE_DELETE` | No | `false` | `true` = disable only delete operations ([details](#disable-delete-operations)) |
| `OUTLINE_DISABLE_AI_TOOLS` | No | `false` | `true` = disable AI tools (for Outline instances without OpenAI) |
| `MCP_TRANSPORT` | No | `stdio` | Transport mode: `stdio` (local), `sse` or `streamable-http` (remote) |
| `MCP_HOST` | No | `127.0.0.1` | Server host. Use `0.0.0.0` in Docker for external connections |
| `MCP_PORT` | No | `3000` | HTTP server port (only for `sse` and `streamable-http` modes) |

## Access Control

Configure server permissions to control what operations are allowed:

### Read-Only Mode

Set `OUTLINE_READ_ONLY=true` to enable viewer-only access. Only search, read, export, and collaboration viewing tools are available. All write operations (create, update, move, archive, delete) are disabled.

**Use cases:**
- Shared access for team members who should only view content
- Safe integration with AI assistants that should not modify documents
- Public or demo instances where content should be protected

**Available tools:**
- Search & Discovery: `search_documents`, `list_collections`, `get_collection_structure`, `get_document_id_from_title`
- Document Reading: `read_document`, `export_document`
- Comments: `list_document_comments`, `get_comment`
- Collaboration: `get_document_backlinks`
- Collections: `export_collection`, `export_all_collections`
- AI: `ask_ai_about_documents` (if not disabled with `OUTLINE_DISABLE_AI_TOOLS`)

### Disable Delete Operations

Set `OUTLINE_DISABLE_DELETE=true` to allow create and update workflows while preventing accidental data loss. Only delete operations are disabled.

**Use cases:**
- Production environments where documents should not be deleted
- Protecting against accidental deletions
- Safe content editing workflows

**Disabled tools:**
- `delete_document`, `delete_collection`
- `batch_delete_documents`

**Important:** `OUTLINE_READ_ONLY=true` takes precedence over `OUTLINE_DISABLE_DELETE`. If both are set, the server operates in read-only mode.

## Adding to Your Client

> **Prerequisites**: Install `uv` with `pip install uv` or from [astral.sh/uv](https://docs.astral.sh/uv/)

<details>
<summary><b>Add to Claude Desktop</b></summary>

Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (or `%APPDATA%\Claude\claude_desktop_config.json` on Windows):

```json
{
  "mcpServers": {
    "mcp-outline": {
      "command": "uvx",
      "args": ["mcp-outline"],
      "env": {
        "OUTLINE_API_KEY": "<YOUR_API_KEY>",
        "OUTLINE_API_URL": "<YOUR_OUTLINE_URL>" // Optional
      }
    }
  }
}
```

</details>

<details>
<summary><b>Add to Cursor</b></summary>

Go to **Settings → MCP** and click **Add Server**:

```json
{
  "mcp-outline": {
    "command": "uvx",
    "args": ["mcp-outline"],
    "env": {
      "OUTLINE_API_KEY": "<YOUR_API_KEY>",
      "OUTLINE_API_URL": "<YOUR_OUTLINE_URL>" // Optional
    }
  }
}
```

</details>

<details>
<summary><b>Add to VS Code</b></summary>

Create a `.vscode/mcp.json` file in your workspace with the following configuration:

```json
{
  "servers": {
    "mcp-outline": {
      "type": "stdio",
      "command": "uvx",
      "args": ["mcp-outline"],
      "env": {
        "OUTLINE_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}
```

For self-hosted Outline instances, add `OUTLINE_API_URL` to the `env` object.

**Optional**: Use input variables for sensitive credentials:

```json
{
  "inputs": [
    {
      "type": "promptString",
      "id": "outline-api-key",
      "description": "Outline API Key",
      "password": true
    }
  ],
  "servers": {
    "mcp-outline": {
      "type": "stdio",
      "command": "uvx",
      "args": ["mcp-outline"],
      "env": {
        "OUTLINE_API_KEY": "${input:outline-api-key}"
      }
    }
  }
}
```

VS Code will automatically discover and load MCP servers from this configuration file. For more details, see the [official VS Code MCP documentation](https://code.visualstudio.com/docs/copilot/chat/mcp-servers).

</details>

<details>
<summary><b>Add to Cline (VS Code)</b></summary>

In Cline extension settings, add to MCP servers:

```json
{
  "mcp-outline": {
    "command": "uvx",
    "args": ["mcp-outline"],
    "env": {
      "OUTLINE_API_KEY": "<YOUR_API_KEY>",
      "OUTLINE_API_URL": "<YOUR_OUTLINE_URL>" // Optional
    }
  }
}
```

</details>

<details>
<summary><b>Using pip instead of uvx</b></summary>

If you prefer to use `pip` instead:

```bash
pip install mcp-outline
```

Then in your client config, replace `"command": "uvx"` with `"command": "mcp-outline"` and remove the `"args"` line:

```json
{
  "mcp-outline": {
    "command": "mcp-outline",
    "env": {
      "OUTLINE_API_KEY": "<YOUR_API_KEY>",
      "OUTLINE_API_URL": "<YOUR_OUTLINE_URL>" // Optional
    }
  }
}
```

</details>

<details>
<summary><b>Docker Deployment (HTTP)</b></summary>

For remote access or Docker containers, use HTTP transport. This runs the **MCP server** on port 3000:

```bash
docker run -p 3000:3000 \
  -e OUTLINE_API_KEY=<YOUR_API_KEY> \
  -e MCP_TRANSPORT=streamable-http \
  ghcr.io/vortiago/mcp-outline:latest
```

Then connect from client:

```json
{
  "mcp-outline": {
    "url": "http://localhost:3000/mcp"
  }
}
```

**Note**: `OUTLINE_API_URL` should point to where your Outline instance is running, not localhost:3000.

cp config/outline.env.example config/outline.env
openssl rand -hex 32 > /tmp/secret_key && openssl rand -hex 32 > /tmp/utils_secret
# Update config/outline.env with generated secrets

# Start all services
docker compose up -d

# Create API key: http://localhost:3030 → Settings → API Keys
# Add to .env: OUTLINE_API_KEY=<token>
```

### Setup

```bash
git clone https://github.com/Vortiago/mcp-outline.git
cd mcp-outline
uv pip install -e ".[dev]"
```

### Testing

```bash
# Run tests
uv run pytest tests/

# Format code
uv run ruff format .

# Type check
uv run pyright src/

# Lint
uv run ruff check .
```

### Running Locally

```bash
uv run mcp-outline
```

### Testing with MCP Inspector

Use the MCP Inspector to test the server tools visually via an interactive UI.

**For local development** (with stdio):

```bash
npx @modelcontextprotocol/inspector -e OUTLINE_API_KEY=<your-key> -e OUTLINE_API_URL=<your-url> uv run python -m mcp_outline
```

**For Docker Compose** (with HTTP):

```bash
npx @modelcontextprotocol/inspector http://localhost:3000
```

## Architecture Notes

**Rate Limiting**: Automatically handled via header tracking (`RateLimit-Remaining`, `RateLimit-Reset`) with exponential backoff retry (up to 3 attempts). No configuration needed.

**Transport Modes**:
- `stdio` (default): Direct process communication
- `sse`: HTTP Server-Sent Events (use for web clients)
- `streamable-http`: Streamable HTTP transport

**Connection Pooling**: Shared httpx connection pool across instances (configurable: `OUTLINE_MAX_CONNECTIONS=100`, `OUTLINE_MAX_KEEPALIVE=20`)

## Troubleshooting

### Server not connecting?

**Check your API credentials:**
```bash
# Test your API key
curl -H "Authorization: Bearer YOUR_API_KEY" YOUR_OUTLINE_URL/api/auth.info
```

Common issues:
- Verify `OUTLINE_API_KEY` is set correctly in your MCP client configuration
- Check `OUTLINE_API_URL` points to your Outline instance (default: `https://app.getoutline.com/api`)
- For self-hosted Outline, ensure the URL ends with `/api`
- Verify your API key hasn't expired or been revoked

### Tools not appearing in client?

- **Read-only mode enabled?** Check if `OUTLINE_READ_ONLY=true` is disabling write tools
- **Delete operations disabled?** Check if `OUTLINE_DISABLE_DELETE=true` is hiding delete tools
- **AI tools missing?** Check if `OUTLINE_DISABLE_AI_TOOLS=true` is disabling AI features
- Restart your MCP client after changing environment variables

### API rate limiting errors?

The server automatically handles rate limiting with retry logic. If you see persistent rate limit errors:
- Reduce concurrent operations
- Check if multiple clients are using the same API key
- Contact Outline support if limits are too restrictive for your use case

### Docker container issues?

**Container won't start:**
- Ensure `OUTLINE_API_KEY` is set: `docker run -e OUTLINE_API_KEY=your_key ...`
- Check logs: `docker logs <container-id>`

**Can't connect from client:**
- Use `0.0.0.0` for MCP_HOST: `-e MCP_HOST=0.0.0.0`
- Verify port mapping: `-p 3000:3000`
- Check transport mode: `-e MCP_TRANSPORT=streamable-http`
