API Reference
Authentication
BCRA's Estadísticas Cambiarias and Variables APIs are public — no API key, OAuth token, or signed request required. The MCP server makes plain HTTPS GETs to api.bcra.gob.ar.
If your organization fronts the BCRA endpoints with a corporate gateway that requires auth, set the gateway's URL via the network egress policy and tunnel through it; the MCP server itself doesn't need credential plumbing.
Enterprise
Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.
