Getting started

Welcome to convention.sh

A hosted MCP server that ships your TypeScript conventions to coding agents one snippet at a time, exactly when they need them.

convention.sh runs as a remote Model Context Protocol server. Drop the URL into any MCP-aware agent — Claude Code, Cursor, Codex, Amp — and your agent gains access to a curated library of production-grade TypeScript rules.

Why use it

Smaller prompts, smaller bills. Conventions are fetched on demand instead of being stuffed into every system prompt — agents pull only the rule they need, when they need it.
Always up to date. Rules live on our hosted server. We ship a new convention; your agents pick it up on the next request.
One source of truth. No more stale CLAUDE.md files sprinkled across repos and machines.
