CogniRelay v1.4.6 Release Notes

Release date: 2026-04-26

CogniRelay v1.4.6 is a focused MCP startup compatibility patch for standard request metadata. It fixes clients that send MCP-reserved params._meta during startup or request-method calls.

Highlights

• tools/list now accepts object-valued params._meta and returns the tool catalog instead of failing with unexpected tools/list param.
• initialize, tools/list, tools/call, and runtime MCP help/reference request methods now accept and ignore object-valued params._meta.
• Actual tool arguments remain strict application payloads. _meta inside tool arguments is not treated as request metadata.
• The regression suite now replays the previously failing startup path: initialize with clientInfo.title, followed by tools/list with params._meta.

Compatibility Notes

• Supported MCP protocol versions remain 2025-06-18 and 2025-11-25.
• clientInfo implementation metadata compatibility from v1.4.5 is preserved.
• Non-object params._meta fails deterministically with -32602 Invalid params.
• Unknown non-metadata request params still fail deterministically.
• No MCP tool schema, HTTP route, schedule, graph, continuity, or UI response shape changed.
• The GET /v1/capabilities version field remains the capability schema version ("1").
