Remote URL or a command on your machine? How the two installs differ
Run on PlugMCP
A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
LaunchFrom the publisher
A business phone line with a secretary: get a number, answer missed calls, take messages, read calls.
Get a business number (or keep yours) with Kai built in. Your phones ring first; Kai answers misses and after-hours calls, takes the details and texts you. See current plans and pricing. This repository is the for the hosted KaiCalls MCP server — it documents the endpoint, authentication, and tool catalog so MCP clients and directories can discover and connect to it.
A phone number for your business or your AI agent. Kai answers it and calls businesses for you.
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.
What is the KaiCalls MCP connector? It is the official hosted MCP connector for KaiCalls. Existing customers use https://www.kaicalls.com/api/mcp; a first-time buyer can use the setup-only surface at https://www.kaicalls.com/api/mcp/acquisition.
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.
Add a custom connector pointing at https://www.kaicalls.com/api/mcp for an existing
account, or the acquisition endpoint for setup. 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.
Pass a KaiCalls API key directly — no OAuth round-trip needed:
Authorization: Bearer kc_live_xxxxxxxxxxxxxxxxxxxx
(X-KaiCalls-API-Key: kc_live_... is also accepted.) Generate keys in the KaiCalls
dashboard under Settings → API Keys. See docs/authentication.md.
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 kc_live_ key.
For Cline, edit cline_mcp_settings.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 kc_live_YOUR_KEY 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.
gemini extensions install https://github.com/KaiCalls/kaicalls-mcp
agy plugin install https://github.com/KaiCalls/kaicalls-mcp
Both connect to the hosted server at https://www.kaicalls.com/api/mcp and sign
you in with OAuth the first time a tool runs.
Most clients should connect to the hosted server at https://www.kaicalls.com/api/mcp. For stdio-only clients, this repo ships a small bridge with no dependencies:
docker build -t kaicalls-mcp .
docker run -i --rm -e KAICALLS_API_KEY=kc_live_... kaicalls-mcp
# or without Docker: KAICALLS_API_KEY=kc_live_... node stdio-proxy.mjs
initialize and tools/list work without a key. tools/call needs KAICALLS_API_KEY, which you create at https://www.kaicalls.com/dashboard/settings/api-keys.
The account endpoint exposes 87 tools: 46 read-only and 41 write/setup. Every tool carries MCP
safety annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint).
The setup endpoint (/api/mcp/acquisition) exposes the 37 tools marked Yes in the
Setup surface column, the subset that takes a new business from signup to a working number.
The machine-readable inventory, with full descriptions, scopes and annotations, is in
mcp.json and server-card.json. In-depth notes for the core
tools are in docs/tools.md. The live tools/list response returns each tool's
input schema.
Write-tool safety. Tools marked destructive change live business configuration or reach the outside world:
make_callplaces an outbound voice preview,send_smssends a real text through opt-out, Do-Not-Call and quiet-hours gates, andcreate_campaigncan queue outbound calls.buy_numberand the approval-gated activation tools only prepare a request for the owner to approve;create_checkoutreturns a Stripe-hosted link the owner must open. Prompt changes route through the governed broker, need an idempotency key plus human authority or a queued approval, and every outcome is audited.
The server is hosted, so the only configuration is authentication. Pick one:
The same choice is declared in server.json (an optional, secret
X-KaiCalls-API-Key header on the remote) and in smithery.yaml
(an optional kaicallsApiKey config field). Leave the key empty to use OAuth.
All return 200 and are CORS-open:
Registry id: com.kaicalls/kaicalls (published & active). The registry entry is generated from
server.json; the Smithery listing from smithery.yaml.
The 1.1.0 metadata in this source change is a registry candidate. Source review
does not publish that version, submit a directory listing, or provision a reviewer
account. Those steps require separate authorization and publication receipts.
Yes. KaiCalls supports MCP through its hosted connector at https://www.kaicalls.com/api/mcp. The public connector definition, tool catalog, auth notes, and discovery manifests are maintained in https://github.com/KaiCalls/kaicalls-mcp.
Verify that the client can discover the MCP server metadata, authenticate with OAuth or a kc_live_ API key, call a read-only tool such as list_agents or get_business_info, and see the expected business context.
Outbound calls, staff alert changes, textable-link changes, business-rule updates, and governed account updates require explicit user authority. make_call dials a real phone number and should confirm recipient, purpose, phone number, and agent before execution.
Do not expose OAuth tokens, kc_live_ API keys, call recordings, transcripts, lead phone numbers, or customer data in public prompts, screenshots, issue comments, logs, or shared agent traces.
