Robert Findley	3430e2242e	mcp: add Capabilities fields to ServerOptions and ClientOptions (#713) ... This allows users to configure default capabilities, disable defaults, or suppress listChanged notifications by setting ListChanged: false. Key changes: - Add ServerOptions.Capabilities and ClientOptions.Capabilities fields. - Merge user-provided capabilities with dynamically-added ones (tools, prompts, resources, sampling, elicitation). - Check ListChanged before sending list-changed notifications. - Deprecate HasPrompts, HasResources, HasTools on ServerOptions. - Remove unreleased ElicitationModes field from ClientOptions. - Add clone methods to capability structs using shallowClone helper. - Add synctest-based tests for notification behavior (go1.25). - Add TestClientCapabilitiesOverWire and TestServerCapabilitiesOverWire - Document the new Capabilities API in docs/ Updates #706	2025-12-11 20:17:46 -05:00
Robert Findley	2ce44d45e9	all: expose JSON-RPC error codes, and support URLElicitationRequired errors (#655) ... Expose the jsonrpc.Error type to allow access to underlying JSON-RPC error codes. Also, expose common JSON-RPC error codes in the jsonrpc package, and MCP error codes in the mcp package. Also, implement support for the MCP URL elicitation required error (-32042), enabling servers to request out-of-band user authorization and clients to automatically handle these requests with retry logic. Server-side: - Add CodeURLElicitationRequired constant - Add URLElicitationRequiredError() constructor. Client-side: - Add urlElicitationMiddleware to intercept URLElicitationRequired errors and retry calls. - Update callElicitationCompleteHandler to signal waiting operations. - Fix capability advertisement to support both form and URL modes.
