Best for
  • Individuals or teams already using Trello for task management who want to manipulate cards and lists conversationally via Claude Desktop or Cursor
  • Developers who want quick Trello access from Claude Desktop or any SSE-capable MCP client
  • Teams and individuals who already manage docs/wikis in Notion and want AI clients (Claude Desktop, Cursor, etc.) to operate on that content directly
  • Developers who want to self-host a local MCP server rather than use a remote hosted option
  • Automation/agent workflows that need to query or update Notion database records programmatically
Not for
  • Users who need to create, rename, or delete entire boards (not supported)
  • Users without a Trello API Key/Token or without access to the Trello Power-Up admin page
  • Scenarios requiring official Trello/Atlassian support or enterprise-grade security auditing
  • Users who want the standard-OAuth, zero-JSON-config install with active official support — Notion recommends its newer remote Notion MCP server for that
  • Users uncomfortable handing a Notion integration token to a locally-run LLM client
  • Use cases needing capabilities the integration deliberately excludes, such as deleting databases
  • Long-term production deployments that need guaranteed maintenance, given this repo may be sunset
Required permissions
  • A Trello API Key and Token (account-level access to read/write boards, lists, cards, and checklists the account can access)
  • Local .env file storing credentials in plaintext
  • Network access to call the Trello API, and (in SSE mode) an open local HTTP port
  • A Notion internal integration token (NOTION_TOKEN or the Authorization value in OPENAPI_MCP_HEADERS), scoped by that integration's Capabilities (can be limited to read-only)
  • Access limited to the specific pages/databases explicitly connected to the integration, not the whole workspace
  • A separate bearer auth token when using the Streamable HTTP transport (--auth-token / AUTH_TOKEN)
  • Network access to the Notion API
Risks and side effects
  • API Key and Token are stored in plaintext in the .env file — leakage grants full control over the Trello account
  • Delete/archive operations on lists, cards, checklists, and checklist items are irreversible
  • SSE mode exposes a local HTTP endpoint; the README does not mention any built-in authentication for it
  • This is a community-maintained third-party server, not reviewed or endorsed by Trello/Atlassian
  • If the integration is granted broad read/write capabilities and connected to many pages, that content is effectively exposed to the LLM, risking data leakage or unintended edits
  • Running with --unsafe-disable-auth removes bearer authentication on the HTTP transport, potentially making it reachable via DNS rebinding from pages a user visits — the README says to only use it on an isolated network
  • Multi-tenant token passthrough requires careful TLS/gateway configuration; misconfiguration risks leaking or misrouting Notion tokens between tenants
  • The README states this local server may be sunset in favor of the remote Notion MCP, and that issues/PRs here are not actively monitored, so long-term maintenance and security fixes are not guaranteed
  • Storing NOTION_TOKEN or OPENAPI_MCP_HEADERS directly in shared client config files risks leaking the secret
