Installation

Option 1: Using Claude CLI (Recommended)

The easiest way to install is using the Claude CLI with npx:

claude mcp add --transport stdio focalboard \
  --env FOCALBOARD_HOST=https://your-focalboard-instance.com \
  --env FOCALBOARD_USERNAME=your-username \
  --env FOCALBOARD_PASSWORD=your-password \
  -- npx -y github:gmjuhasz/focalboard-mcp-server

Replace the environment variable values with your actual Focalboard credentials:

• FOCALBOARD_HOST: Your Focalboard instance URL (e.g., https://focalboard.example.com)

• FOCALBOARD_USERNAME: Your Focalboard username or email

• FOCALBOARD_PASSWORD: Your Focalboard password

Alternatively, if you've cloned the repository locally:

cd /path/to/focalboard-mcp-server
npm install
npm run build

claude mcp add --transport stdio focalboard \
  --env FOCALBOARD_HOST=https://your-focalboard-instance.com \
  --env FOCALBOARD_USERNAME=your-username \
  --env FOCALBOARD_PASSWORD=your-password \
  -- node /absolute/path/to/focalboard-mcp-server/build/index.js

Option 2: Manual Installation

1. Clone or download this repository

2. Install dependencies:

npm install

Usage Examples

Getting Started

1. List your boards:

   List all my Focalboard boards

2. Get board details to see columns:

   Show me the details of board [board-id], including all columns

3. Create a new task:

   Create a task in board [board-id] titled "Review pull request" with Status "To Do"

4. Move a task to another column:

   Update card [card-id] in board [board-id], change Status to "Done"

Workflow Example

User: "List all my boards"
Claude: [Shows list of boards with IDs]

User: "Get details for board abc123"
Claude: [Shows board with property definitions, including Status column options]

User: "Create a card in board abc123 titled 'Fix bug in authentication' with Status 'To Do' and Priority 'High'"
Claude: [Creates card and returns the new card ID]

User: "Get all cards from board abc123"
Claude: [Shows all cards in the board]

User: "Update card xyz789, move it to 'In Progress'"
Claude: [Updates the card's Status property]

Working with Descriptions

User: "Create a task in board abc123 titled 'Implement OAuth' with description 'Add Google and GitHub OAuth providers'"
Claude: [Creates card with description]

User: "Show me the description of card xyz789"
Claude: [Retrieves and displays the card's content blocks including the description]

User: "Update card xyz789 description to include implementation details"
Claude: [Updates the card's description]

User: "Add a description to card abc456 explaining the requirements"
Claude: [Adds a new description to an existing card]

Markdown Support: Descriptions support full markdown formatting:

• Bold and italic text

• Lists (ordered and unordered)

• Code blocks: `inline code` or ``` code block ```

• Headers (# H1, ## H2, etc.)

• Links: text

• And more!

How It Works

Authentication

The server automatically handles authentication:

1. When first called, it logs in with your username/password

2. Receives a session token from Focalboard

3. Uses the token for all subsequent API requests

4. Automatically re-authenticates if the token expires

Column Name Resolution

When you update a card with property names (e.g., "Status": "In Progress"):

1. The server fetches the board details

2. Finds the property by name (case-insensitive)

3. Resolves the column/option name to its internal ID

4. Updates the card with the correct ID

This means you can use friendly names like "To Do" instead of remembering cryptic IDs like "option-abc123".

API Reference

This server uses the Focalboard API v2. For more details, see:

• Focalboard API Documentation

• Focalboard GitHub Repository

Troubleshooting

Authentication Errors

If you see authentication errors:

• Verify your FOCALBOARD_HOST is correct (should include https://)

• Check your username and password are correct

• Ensure your Focalboard instance is accessible

Board or Card Not Found

• Use list_boards to get the correct board IDs

• Use get_cards to get valid card IDs

• Board and card IDs are case-sensitive

Property Not Found

• Use get_board to see all available properties and their names

• Property names are case-insensitive but must match exactly

• For select/multiSelect properties, option values must match available options
