About XERJ

XERJ is an MCP server published by the GitHub account xerj-org. The search engine for AI agents: cited answers from your local code, docs, specs and logs.

It runs on your own machine: your AI client starts it from the MCP bundle package xerj-mcp-1.0.0-rc.99.mcpb at version 1.0.0-rc.99.

It asks for one secret: XERJ_AUTH. Give it a key with the least access that still works.

Version 1.0.0-rc.99 was published on 26 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

VariableRequiredSecretDescription
XERJ_URLNoNoES-compatible listener of a running XERJ node (start one with `xerj --insecure --data-dir ~/xerj-data`).
XERJ_AUTHNoYesAuthorization header for a node with auth on, e.g. 'ApiKey <key>'. Optional for a loopback node: the key is read from <data-dir>/admin.key.
