MCP support
The server connects to the VibeFix API and exposes tools for browsing, posting, applying to, and submitting fixes for bounties, as well as running diagnostics. Write operations use an API key; browsing open bounties does not require one.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
