I build agents.

Tatrman speaks MCP. Your agent asks questions through a small, versioned surface of doors and tools, forwards the end user's identity, and gets back an answer plus the trail of everything the platform did to keep that answer legal.

This track is the contract, written for you rather than for us.

Start here

• Your first agent against the door — the tutorial: ask one question, read the envelope, see the provenance.

The reference

• The doors and tools — every door, every tool, its arguments, the result envelope, and the refusal modes.
• The identity contract — on-behalf-of: what your agent MUST forward, what comes back, and why an agent that guesses instead of refusing is a bug.
• The compatibility rule — what the platform may change under you, and what it may not.

Prove it

• The conformance suite as your test harness — the same fixtures the platform gates on, pointed at your agent. Each fixture doubles as a worked example, so it cannot rot into fiction.

Framework specifics (LangGraph, Koog, MCP-capable assistants) differ only in how you register a door and attach the bearer — the tutorial's four steps are the same everywhere; framework-specific how-tos land as the reference agents publish.
