Vapi MCP Server - Build AI voice assistants with Claude
Vapi MCP Server - Build AI voice assistants with Claude. That is what the vapi mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The easiest way to get started. No API key needed - authenticate via browser on first use.
Because 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.
The server publishes 9 tools. What each one is for:
vapi_list_tools — List custom toolsvapi_get_tool — Get tool detailsvapi_create_tool — Create tool for API integrationvapi_update_tool — Update toolvapi_delete_tool — Delete toolAssistants — The Assistants tool exposed by this serverCalls — The Calls tool exposed by this serverAuthentication — The Authentication tool exposed by this serverTesting — The Testing tool exposed by this serverConfiguration is passed through the environment: VAPI_TOKEN. 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.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Vapi's toolset — vapi_list_tools, vapi_get_tool, vapi_create_tool and 6 more — is a fair guide to whether it matches your workflow. It is maintained by yassinnouh21; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
