v0.20.1

on GitHub

The MCP server now speaks every protocol revision from 2024-11-05 through 2026-07-28, so newer clients that negotiate a recent revision — or probe with server/discover — connect cleanly instead of being pinned to 2025-06-18. Two initialize edge cases are fixed along the way: a request missing protocolVersion now gets a proper JSON-RPC error instead of a silent exit, and an unknown version is answered with one the server actually supports rather than echoed back.

Changed

• MCP protocol support now spans revisions 2024-11-05 through 2026-07-28 (was capped at 2025-06-18), including the server/discover method

Fixed

• An initialize request without a protocolVersion receives a JSON-RPC error response (previously the server exited without answering)
• Version negotiation no longer echoes back an unknown protocol version; the server answers with a revision it supports
