### Why slim-tg-mcp?

The popular `chigwell/telegram-mcp` exposes **73 tools** — that's roughly
**11 000 tokens** permanently consumed in every conversation. This project
keeps only **8 search/read tools** as MCP and ships every write/admin
operation as a **lazy-load Skill**. Same capabilities (now with feature
parity at v0.4.0 across **11 Skills**), **~87 % less context overhead**,
and a security model designed from day one to survive prompt injection.
