Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Tirith

Coordination server for parallel coding agents. Claims, a task board, interface contracts, change notices, a decisions log, path-scoped memory notes, and agent messages, over MCP.

Run five or ten coding agents on one repository and they edit the same files, rename things others depend on, and build both sides of an interface to different shapes. Tirith is a small daemon they all talk to: an agent claims files before editing, gets the notices, contracts, decisions, and notes for those files back with the claim, and publishes the shape of an interface before either side implements it.

It works with anything that speaks MCP, over stdio or HTTP: Claude Code, Cursor, Codex, LangGraph, CrewAI, or a plain script.

It also remembers. Agents leave notes scoped to repository paths, so what one agent learned about a file reaches the next agent that claims it. Tirith stores no conversation history and no embeddings.

Status: v1 shipped. Every primitive, the CLI, persistence, and the dashboard are built and tested, against the definition in ADR-0013; tool schemas follow semantic versioning.

Questions

What is the tirith MCP server?

The tower of guard for parallel coding agents. Keeps parallel coding agents from stepping on each other. Claims, contracts and change notices over MCP.

Is tirith safe to connect to an agent?

With care. The audit graded it B (89/100) and found 15 things worth knowing before you trust this server, listed below with the exact line each was found on.

What credentials does tirith need?

No credential environment variables were found in its source, so it appears to need none.

How does tirith run?

It speaks stdio and streamable-http, so it runs as a local process your client starts.

How current is this page?

The grade is for one exact copy of the source (1382ef824c0f), read on 2026-10-12. The repository is watched and re-audited when it changes.
