Why

OpenHands users can run Pilot Protocol as a local stdio MCP server without credentials, but it is not available in the integration catalog.

Notes

Disclosure: I contribute to Pilot Protocol. AI-assisted; reviewed and validated against the repository schema and test suite.

HUMAN: No manual UI test was performed. The repository test suite, both synchronization checks, generated integration index, schema validation, and Claude plugin validation were run locally; the exact results are recorded above.

👋 This PR needs a couple of things fixed before OpenHands can review it:

• the PR description's HUMAN: section needs at least 20 characters describing what you tested, not just the template placeholder

Push an update once this is addressed and this check re-runs automatically.

The latest PR Description Check now passes. The required test, sync-extensions, and validate-claude-code workflows are awaiting first-time fork approval (action_required). I ran their commands locally: 801 tests passed, 24 skipped; both sync checks passed; all bundled plugins passed Claude validation. Could a maintainer approve the fork workflows?
