MCP Server Trello (delorenj) + Claude Desktop FAQ

Where is the Claude Desktop config file?

Claude Desktop reads MCP servers from ~/Library/Application Support/Claude/claude_desktop_config.json. Paste the MCP Server Trello (delorenj) config there under the "mcpServers" key and restart the client.

Is MCP Server Trello (delorenj) safe to use with Claude Desktop?

Requires a Trello API key and user token that grant access to your boards; store both in env vars and use TRELLO_ALLOWED_WORKSPACES to restrict scope. Tokens are long-lived, so revoke them from Trello if exposed.

Where do I get the API key and token?

Create the API key at https://trello.com/app-key, then use it to generate a user token (also linked from that page). Set them as TRELLO_API_KEY and TRELLO_TOKEN.

Can I use more than one board?

Yes. Use set_active_board / set_active_workspace to switch context at runtime — preferences persist to ~/.trello-mcp/config.json — and most tools also accept an optional boardId. The older TRELLO_BOARD_ID env var is deprecated but still supported.

Will it hit Trello's rate limits?

It implements a token-bucket limiter matching Trello's quotas (300/10s per key, 100/10s per token) and automatically queues requests that would exceed them, so you avoid 429 errors.
