What is the SpecLeft MCP server?

If you already use SpecLeft, the specleft mcp server is the piece that lets your assistant work with it directly. Python intent tracing MCP: map specs to pytest tests, monitor implementation progress, offline-only.

What the server does

SpecLeft keeps feature intent and test coverage aligned by turning plans into version-controlled specs, then generating pytest test skeletons from those specs.

Available tools

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

Installation

specleft on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

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. SpecLeft's toolset — Roadmap — is a fair guide to whether it matches your workflow. It is maintained by SpecLeft; 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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.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

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
