Show HN: Crossbeam-CLI – Connect Claude to Crossbeam without the enterprise tier
An open-source tool that connects Claude to Crossbeam's internal API, letting users query partners and account mapping in plain English on any plan, including the free tier. It ships as a Claude desktop extension and CLI, but is unofficial and uses undocumented endpoints that could break at any time.
Background
- Crossbeam is a SaaS platform that helps B2B companies manage "co-sell" partnerships — it shows two companies which customers and accounts they share, so they can coordinate sales efforts.
- Claude is Anthropic's AI assistant. It can be extended with "tools" via the MCP (Model Context Protocol), letting it read/write external systems.
- Crossbeam charges thousands per year for its API (the "Supernode" enterprise tier). Free and mid-tier plans only give you the web interface.
- This open-source tool logs into Crossbeam using your regular credentials (not the paid API) and exposes your data to Claude through MCP. It uses undocumented internal endpoints, so Crossbeam could break it at any time. Not affiliated with Crossbeam.
