Locus

Locus is pay-per-use API infrastructure. One MCP server fronts thousands of provider endpoints (search, enrichment, scraping, finance and market data, and more) behind eight compact tools. Paid provider calls bill the workspace's single prepaid credit balance; discovery, quotes, and balance checks are free. No per-provider accounts, no per-provider keys.

Connection

The server is streamable HTTP at:

https://api.paywithlocus.com/api/credits/mcp

Auth is OAuth, discovered from that URL through the client's standard MCP authentication flow. The URL is the entire durable configuration; the runtime keeps the tokens.
