Rhumb Mcp

Rhumb is an agent gateway that scores and routes external tool calls. It indexes over 1,000 services with AN Scores that measure execution quality and access friction, then routes supported capability calls through governed execution rails. Think of it as discovery plus routing: find_services and get_score help agents compare options like Stripe or SendGrid before committing, while execute_capability routes the actual call through the best available provider based on health, cost, and credentials. It exposes 21 MCP tools covering discovery, execution estimates, receipts, and budget enforcement. Discovery works without auth. Execution requires a governed API key or wallet prefund. Best current fit is research, extraction, and generation tasks rather than broad multi-system automation.
