What the publisher says
From the Nats Trail repository's README, as published. We do not edit it. Read it on GitHub
Give an AI agent safe access to your production event bus. A web UI, a CLI and an MCP server over one bounded query engine — so humans and agents debug NATS from the same source of truth.
Why this exists
Every NATS GUI answers "what is in this stream?". That is the easy question.
The hard question in an event-driven system is "why did this one flow fail?" — and answering it means following a single request_id across four streams, three services and a dead-letter subject. Today you do that by hand, with a terminal per stream.
NATS Trail answers that question directly, and exposes the answer to agents as a typed, bounded, read-only tool contract — so you can point Claude at production and ask.
nats-trail trace --request-id req-0001d --limit 20Or, from an agent: "Why did the refresh for s3-events fail?" — and it lands on the message that actually broke, with the retry state and the correlation ids already extracted:
The part nobody else does
There are several NATS MCP servers. They shell out to the nats CLI, return raw dumps, and expose publish and delete while describing themselves as read-only.
NATS Trail treats the agent surface as a contract, not a wrapper:
"Read-only" here means unreachable, not disabled
NATS Trail can write: publish, purge, delete messages, consumers and streams. Those live behind /api/mutate, reachable from the UI and the CLI.
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
