KaiCalls — Claude Code MCP server: what it does, how to install
Connects AI assistants to the KaiCalls phone platform to review transcripts, inspect call logs, and manage agents.
claude mcp add --transport http kaicalls https://www.kaicalls.com/api/mcpWhat KaiCalls does
KaiCalls provides an official hosted connector that links MCP clients directly to your business telephony. It gives agents access to incoming conversations, audio recordings, and lead summaries without running software on your own machine. All communication runs over Streamable HTTP against https://www.kaicalls.com/api/mcp.
The production catalog includes 87 tools, split between 46 read operations and 41 modification tools. First-time workspace configuration can instead target the acquisition route with 37 tools. Authentication relies on OAuth 2.1 or a kc_live_ key sent as a Bearer token. For Cline users, setting the transport parameter strictly to camelCase streamableHttp is required to avoid falling back to SSE and getting an immediate 405 error.

- fetch full transcripts and audio URLs for recent calls
