What is the Codexa MCP server?

Connect Codexa to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Codex-native codebase intelligence context compiler and query-only MCP server. The codexa mcp server is what makes that connection.

What the server does

Codexa is a local change-evidence layer for human and agentic software workflows: committed-change receipts, plan conformance, blast-radius review, and verification crediting built on a deterministic codebase map.

  • One committed-change receipt. — codexa review resolves an explicit Git
  • A drift loop. — change_plan snapshots per-file hashes plus symbol and
  • Exact checkout identity. — Every query validates that the index belongs to
  • A verification ledger. — Commands the agent reports are parsed against a
  • Compaction-safe continuity. — Session decisions, rejected hypotheses,
  • Graph-aware relational packets. — v0.7.0 precomputes bounded process

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Compaction — safe continuity.** Session decisions, rejected hypotheses,
  • Graph — aware relational packets.** v0.7.0 precomputes bounded process
  • read — first files selected from the task and graph context;
  • Host — Best install

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Codexa's toolset — Compaction, Graph, read and 1 more — is a fair guide to whether it matches your workflow. It is maintained by mirnoorata; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Codexa to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (Compaction, Graph, read, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Codexa directly.
