Integration

Vapi integration

Vapi is a Voice AI platform for building, testing, and deploying voice AI agents. Create conversational AI assistants that can handle phone calls, integrate with various LLMs (OpenAI, Anthropic, etc.), use custom voices, and connect to external tools and APIs. Perfect for customer support automation, appointment scheduling, lead qualification, and interactive voice response systems.

What you can do with Vapi

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use Vapi from Claude Code, Cursor or Codex

Connect Vapi in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Vapi operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
