About nats-trail
nats-trail is an MCP server published by the GitHub account solsolettidev. Read-only NATS and JetStream observability: trace a request across streams, rank what is broken.
It runs on your own machine: your AI client starts it from the npm package @nats-trail/mcp at version 0.6.1.
It asks for one secret: NATS_TRAIL_TOKEN. Give it a key with the least access that still works.
Version 0.6.1 was published on 3 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
NATS_TRAIL_API | No | No | URL of the NATS Trail bridge, e.g. http://127.0.0.1:4000. Without it the server answers only from local state and cannot reach JetStream. |
NATS_TRAIL_TOKEN | No | Yes | Bearer token for the bridge, required when it has auth enabled. A read-scoped token is enough: this server never mutates. |
