CogniRelay v1.4.5 Release Notes

Release date: 2026-04-26

CogniRelay v1.4.5 is a focused MCP startup compatibility patch. It fixes standards-compatible clients whose initialize request includes optional clientInfo implementation metadata.

Highlights

• initialize now accepts standard MCP implementation metadata fields under clientInfo: title, description, websiteUrl, and icons.
• The exact observed Codex startup payload with clientInfo.title now succeeds.
• The compatibility fix is not Codex-specific; it applies to the supported MCP protocol versions 2025-06-18 and 2025-11-25.
• Immediate tools/list after successful initialize remains supported.

Compatibility Notes

• Top-level initialize.params remains strict: protocolVersion, capabilities, and clientInfo.
• clientInfo.name remains required when clientInfo is present.
• Unknown clientInfo fields still fail deterministically with -32602 Invalid params.
• 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").

Verification

Release preparation should pass:

git diff --check
./.venv/bin/python -m ruff check app tests tools
./.venv/bin/python -m unittest discover -s tests -v
