KaiCalls MCP server

KaiCalls MCP Server

AI-powered phone answering service for businesses — exposed as a remote Model Context Protocol server.

KaiCalls gives a business its own phone number in 3 minutes. Calls ring the owner's cell first; Kai handles overflow, texts, voicemail, missed-call alerts, outbound campaigns, lead intake, and appointment scheduling. This repository is the public connector definition for the hosted KaiCalls MCP server — it documents the endpoint, authentication, and tool catalog so MCP clients (Claude, ChatGPT, Cursor, and any MCP gateway) and directories can discover and connect to it.

The KaiCalls platform itself is a hosted SaaS — there is no server to install. You connect to the live endpoint below with your KaiCalls account.

Quick Answer

What is the KaiCalls MCP connector? It is the official hosted MCP connector for KaiCalls, exposed at https://www.kaicalls.com/api/mcp.

Who should use it? Use it when Claude, ChatGPT, Cursor, an MCP gateway, or another AI client needs to safely inspect KaiCalls agents, calls, transcripts, leads, analytics, and approved setup actions.

Does it require hosting your own server? No. KaiCalls hosts the MCP server. Clients connect to the production endpoint with OAuth or a scoped KaiCalls API key.

Is this the WordPress plugin? No. The approved KaiCalls AI Intake plugin captures website leads from WordPress. This repo documents the agent/MCP connector.

Is this the n8n integration? No. n8n workflows should use n8n-nodes-kaicalls.

Quick connect

Claude (web & desktop) / ChatGPT

Add a custom connector pointing at https://www.kaicalls.com/api/mcp. Sign in with your KaiCalls account, pick the business on the consent screen, and Allow. See docs/quickstart.md for screenshots and per-client steps.

API-key clients / MCP gateways

Pass a KaiCalls API key directly — no OAuth round-trip needed:

Authorization: Bearer kc_live_xxxxxxxxxxxxxxxxxxxx

(X-KaiCalls-API-Key: kclive... is also accepted.) Generate keys in the KaiCalls dashboard under Settings → API Keys. See docs/authentication.md.

Cline / remote MCP clients

KaiCalls is a remote server — there is nothing to clone or install. Add it to your MCP client config as a Streamable HTTP server and authenticate with a kclive key. For Cline, edit clinemcpsettings.json (or use the Remote Servers tab) and add:

{
  "kaicalls": {
    "url": "https://www.kaicalls.com/api/mcp",
    "type": "streamableHttp",
    "headers": { "Authorization": "Bearer kc_live_YOUR_KEY" }
  }
}

Replace kcliveYOURKEY with a key from the KaiCalls dashboard under Settings → API Keys**. The transport type must be the camelCase string streamableHttp — using streamable-http or omitting it makes Cline fall back to SSE and the connection fails with a 405. Once saved, Cline lists the KaiCalls tools and is ready to use. See llms-install.md for the full agent-driven setup walkthrough.

Tools

13 read-only tools and 5 write/setup tools. Full input/output schemas and safety annotations are in docs/tools.md; the machine-readable inventory is in mcp.json and server-card.json.
