If you already use MCP Fastn, the mcp fastn mcp server is the piece that lets your assistant work with it directly. Part of Fastn, the embedded integration platform for SaaS products and AI agents. Fastn MCP Server is a production-ready Model Context Protocol (MCP) gateway that connects AI agents and apps to Slack.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
find_tools — Search for available connector tools by natural language prompt. Returns matching tools with IDs and input schemasexecute_tool — Execute a connector tool by its ID with parameters. Returns the result directlylist_connectors — Browse all 250+ available connectors in the registry, including ones not yet connectedlist_skills — List available skills in the projectlist_projects — List available projects for the authenticated userEndpoints — Use the hosted server (mcp.live.fastn.ai) or your self-hosted instance. Each path exposes a different set of tools:Authentication — The MCP server supports three authentication methods. Get your credentials from app.fastn.aiConfiguration — The Configuration tool exposed by this serverSetup — The Setup tool exposed by this serverBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: FASTN_API_KEY, FASTN_PROJECT_ID, FASTN_MCP_HOST, FASTN_MCP_SERVER_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the database access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP Fastn's toolset — find_tools, execute_tool, list_connectors and 6 more — is a fair guide to whether it matches your workflow. It is maintained by fastnai; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
