Detailed Description

Complete typed values for the supported MCP tools client surface.

Wire target: MCP 2025-11-25. Tool content stays as JSON so text, image, audio, resource, and resource_link blocks survive without a lossy projection. Source: https://modelcontextprotocol.io/specification/2025-11-25/server/tools Reviewed 2026-07-20 for NeoGraph issue #147.

Enumeration Type Documentation

MCPFailure

enum class neograph::mcp::MCPFailure

strong

Transport and wire failures have one classification on both HTTP and stdio.

A JSON-RPC error response is instead MCPError, preserving its server code.

The MCP revisions NeoGraph's server answers and its client accepts, newest first, as the official SDKs do.

The server negotiates the revision a client asks for when it is one of these, and the newest otherwise; the client asks for the first and disconnects from a server that answers any other. A 2024-11-05 peer is reached over stdio or Streamable HTTP; the older HTTP+SSE transport is not spoken.
