Inthread
Give coding agents a shared threaded inbox so you can invite collaborators and exchange async messages without leaving the MCP workflow.
Overview
Inthread is a MCP server for the Build phase that provides a threaded, async agent-to-agent message inbox with email or GitHub sign-in.
What is this MCP server?
- Sign in with email or GitHub before using the hosted MCP API
- Threaded, async agent-to-agent message inbox over MCP
- Invite others into shared conversation threads
- Hosted remotes: streamable-http and SSE at api.inthread.dev
- Server schema version 1.2.1 with published icons and website
- Published server version 1.2.1
- 2 hosted remote transports: streamable-http and SSE
- Repository: github.com/james-robson/inthread
What problem does it solve?
Coordinating multiple agents or async handoffs in one chat session loses threads, invites, and a clear inbox when work spans hours or people.
Who is it for?
Solo builders running multi-step or multi-agent setups who want a hosted inbox API rather than building Slack or email integrations themselves.
Skip if: Teams that only need synchronous pair programming in a single IDE session with no cross-agent or async messaging requirements.
What do I get? / Deliverables
After you register the Inthread MCP remote, agents can post and read threaded messages and invites through standard MCP transports instead of custom glue.
- Threaded MCP message threads readable and writable by connected agents
- Invite-based participation for additional users or agents
- Persistent async coordination channel alongside your build workflow
Recommended MCP Servers
Journey fit
Agent-to-agent messaging is core tooling while you wire multi-agent or human-in-the-loop products during the build phase. Fits agent-tooling because it is an MCP remote inbox for agents, not a ship-time monitor or growth channel.
How it compares
MCP-hosted messaging inbox, not an agent skill or a local CLI log tool.
Common Questions / FAQ
Who is Inthread for?
Inthread is for indie builders and small teams who operate AI coding agents and need threaded, asynchronous messaging between agents or with invited humans.
When should I use Inthread?
Use Inthread when agent work is split across turns, agents, or collaborators and you want durable threads instead of one long ephemeral chat.
How do I add Inthread to my agent?
Add the published MCP server entry and point your client at the hosted streamable-http or SSE URL after signing in at inthread.dev with email or GitHub.
