Core Implementation (packages/agents/src/mcp/rpc.ts) implements RPCClientTransport and RPCServerTransport with full JSON-RPC 2.0 validation, batch request support, and session management.
Agent Integration (packages/agents/src/index.ts) addRpcMcpServer() method to Agent class for connecting to MCP servers via RPC bindings.
McpAgent Support (packages/agents/src/mcp/index.ts) implements handleMcpMessage() with automatic transport recreation after hibernation.
Example (examples/mcp-rpc-transport/) showing Agent calling McpAgent via RPC with counter tool.
Documentation (docs/mcp-transports.md) guide covering all three transports (Streamable HTTP, SSE, RPC) with step-by-step setup.
Tests (packages/agents/src/tests/mcp/transports/rpc.test.ts)
Closes #548
