About Convex MCP Server

Connect your Convex deployment to any AI agent and manage your application's data and logic through natural conversation. This server allows you to interact with your real-time database and serverless functions without leaving your AI interface.

Claude Code registers Convex as an MCP server in a single terminal command. Once connected, Claude Code discovers all 4 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Convex data drives decisions without human intervention.

What you can do

  • Data Fetching — Execute read-only queries to retrieve documents and state from your Convex tables.
  • Transactional Updates — Run mutations to modify data with full ACID guarantees directly from the agent.
  • Side Effects & APIs — Trigger Convex actions for external API calls, heavy computation, or non-transactional logic.
  • Flexible Execution — Call functions using standard colon notation or URL-style identifiers for maximum compatibility.

The Convex MCP Server exposes 4 tools through the Vinkius. Connect it to Claude Code in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
