Expand description

MCP protocol versions this server understands, newest first.

2026-07-28 is a modern (stateless, per-request _meta) revision served alongside the legacy (initialize-handshake) revisions in LEGACY_PROTOCOL_VERSIONS — this is a dual-era server. A request carrying _meta["io.modelcontextprotocol/protocolVersion"] is served statelessly; an initialize request selects legacy semantics.
