What it is
JSON-RPC is a lightweight remote-procedure-call protocol that encodes a call as JSON: a method name, a params object, and an id to correlate the response, which comes back as a result or an error.
In the Credicorp MCP server
The MCP endpoint accepts JSON-RPC 2.0 over POST. Clients call standard MCP methods — initialize, tools/list, tools/call — and receive results in kind. A plain GET returns the server card instead, for inspection without a JSON-RPC round trip.
Frequently asked questions
Do I write JSON-RPC by hand?
Usually not. An MCP-compliant client speaks it for you. You only craft it by hand when testing the endpoint directly with curl.
