valorant-mcp

A self-hosted MCP server that gives your AI assistant factual VALORANT account and match data through HenrikDev's API.

Use

  1. Deploy your own copy on Vercel, add a Neon Postgres database from the Vercel Marketplace (sets DATABASE_URL; tables are created on first use), and set the env vars in .env.example.

  2. Open /setup, unlock it with OWNER_PASSWORD, and enter your Riot ID. You get a connector URL, shown once.

  3. Add that URL as a custom connector (MCP server) in Claude, ChatGPT, or any MCP client.

  4. Optionally invite friends from /setup. Each friend accepts on a single-use /claim link and gets their own connector URL.

How it works

  • Consent. Only profiles in consented_profiles are ever looked up: the owner's own account, and friends who accepted an invite. A name/tag that hasn't consented is rejected the same way as one that doesn't exist. Other players appear only as participants in your own matches.

  • Auth. Each connector URL carries a random key (/mcp?key=… or Authorization: Bearer). Only its SHA-256 is stored (connections); revoke it on /setup.

  • Cache. cached_matches is keyed by (operator_puuid, match_id) and bounded to 100 rows per profile. It fails open: a database error never fails a tool call.

  • Errors. Every tool returns { ok, data?, error? } with error.kind of rate (includes retryAfterMs), upstream, schema or input. Messages never include HenrikDev response bodies or player data.

Code lives in lib/ (lib/tools/ has one module per tool), routes in app/, and the schema in lib/db.ts.

Develop

pnpm install --frozen-lockfile
pnpm verify   # format, typecheck, test

Requires Node.js 24 and pnpm 12. Copy .env.example to .env.local for local runs.
