v1.1.0 — May 19, 2026

Release notes for meko-mcp-server v1.1.0 — Meko Token auth, AWS Bedrock support, OpenAI Codex client, three-bucket agent_id model.

The first minor release since 1.0.x. Headline additions: new server auth options (Meko Token + combined PAT/Cognito), AWS Bedrock support, an OpenAI Codex client (CLI + Desktop App), and a fully documented three-bucket agent_id model that gives Claude Code, Cursor, Claude Desktop, and cross-project memory each their own namespace.

New Features

MCP Server

  • Meko Token auth — a PAT-style bearer token auth path, as an alternative to the existing Cognito flow, with support for enabling both simultaneously.
  • AWS Bedrock support — LLM_PROVIDER, LLM_MODEL, EMBEDDER_PROVIDER, and EMBEDDER_MODEL are now env-configurable (supported providers: openai and aws_bedrock).
  • MEKO_SERVER_INSTRUCTIONS — sent on the initialize handshake so LLMs get a use-case-oriented overview without extra prompting.
  • flush_pending_memory_candidates MCP tool — a read-scope tool used by the Desktop skill to compensate for missing hook events. (Deprecated as of v2.0.0.)

Integrations

  • OpenAI Codex client (CLI + Desktop App) — a single install configures both surfaces. The bearer token is resolved from $MEKO_API_KEY at runtime and never written to disk.
  • Three-bucket agent_id model — documented and aligned across the server, hooks, skills, and installer: a per-project bucket (<client>:<repo-basename>), a cross-project common bucket (meko_agent), and a stable bare name for non-coding clients (claude_desktop).
  • Independent Claude Desktop skill (meko-mcp-tools-desktop) — a fully independent plugin with its own setup guide and packaging, using agent_id="claude_desktop".

Changes

MCP Server

  • Breaking: auth header format — API_KEY: <key> → Authorization: Bearer <key> across all clients, hooks, and the .mcpb launcher. The Cloud gateway rejects the legacy header.
  • MCP spec compliance — authorization/connection logic updated to match the latest MCP spec.

Bug Fixes

MCP Server

  • memory_search and conversation_list — conversation_id is now optional, as expected for read-only tools.
  • mcpdebugger.dev compatibility — fixed the /generate-token/callback path under client_secret_basic.

Installer

  • askSecret paste handling — fixed stdin reset between readlines; readline now correctly handles ANSI sequences, bracketed paste, backspace, arrows, and UTF-8.
  • Canary check — switched from a memory_add round trip (which the LLM fact-extractor could non-deterministically return empty for) to the read-only datapack_list call.
