# MCP

> Set up the Brixo MCP server in Claude Code and Codex.

Use the Brixo MCP server to query and analyze your organization message data from AI coding tools.

## What you can do with this MCP server

* Search message data with Elasticsearch DSL using `messages.search`.
* Run aggregation-only queries (`size: 0`) for grouped analytics such as account buckets.
* Fetch latest messages with sorted pagination using `search_after`.
* Limit returned fields with `_source` and inspect allowed fields with `messages.mappings`.
* Retrieve current Elasticsearch mappings for your read scope with `messages.mappings`.
