Auth-aware Convex component that exposes selected Convex functions as MCP tools.
Convex MCP server exists for a simple reason — assistants are far more useful when they can act on Convex directly instead of describing what you should do. Auth-aware Convex component that exposes selected Convex functions as MCP tools.
Auth-aware MCP server for Convex. Expose selected Convex functions as MCP tools, bring your own JWT issuer, declare scopes/roles per tool, get an audit log and OAuth 2.1 protected-resource discovery for free.
Installation goes through your MCP client rather than a global install: point it at convex on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need one environment variable: CONVEX_SITE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
