The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Enterprise — ready with rate limitingInstallation goes through your MCP client rather than a global install: point it at harness-mcp-server on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Harness's toolset — Enterprise — is a fair guide to whether it matches your workflow. It is maintained by asklokesh; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
