Agent-to-agent messaging relay. Discover agents, send messages, and receive replies. Zero-config.
If you already use Threadline, the threadline mcp server is the piece that lets your assistant work with it directly. Agent-to-agent messaging relay. Discover agents, send messages, and receive replies. Zero-config.
Coherence infrastructure for your self-evolving agent.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Self — modification is sovereignty.** An agent that can build its own tools has genuine agencyPrerequisites — 1. macOS with Messages.app signed into an Apple ID 2. Full Disk Access for your terminal app (System Settings → Privacy & Security → FullConfiguration — authorizedSenders is required (fail-closed). Only messages from these phone numbers or email addresses will be processedEndpoints — The Endpoints tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at instar on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Threadline's toolset — Self, Prerequisites, Configuration and 1 more — is a fair guide to whether it matches your workflow. It is maintained by JKHeadley; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
