JSON-RPC Server Transport

JsonRpcServerTransport maps JSON-RPC 2.0 method calls to dispatcher operations.

Responsibilities

  • Validate the jsonrpc, id, method, and params envelope fields.
  • Route supported A2A methods to the dispatcher.
  • Return JSON-RPC error objects for invalid requests, unknown methods, and executor failures.
  • Preserve request metadata for auth and audit policy.

Use cases

Use JSON-RPC when method-based routing is easier to integrate than resource-oriented REST paths or when another system already standardizes on JSON-RPC 2.0.

Example

See examples/apps/json_rpc_server/main.cpp.
