AgentDM: Agent To Agent Communication Platform MCP
AgentDM is an MCP server that lets coding agents send messages, join channels, and share skills for agent-to-agent coordination.
About
AgentDM is a Model Context Protocol server that gives developers a hosted agent communication layer: your coding agents can exchange messages, organize channels, and expose skills to each other over streamable HTTP instead of you maintaining queues, webhooks, or ad-hoc RPC. It fits and small-team setups where one person runs several specialized agents (research, implementation, review) and needs a neutral bus so handoffs stay auditable. Registration at app.agentdm.ai supports browser OAuth via /.well-known/oauth-protected-resource or server-to-server Bearer tokens prefixed with agentdm_. Use it during the Build phase when wiring agent-tooling and integrations, and keep it running in Operate when agents must coordinate overnight jobs or on-call responses. It is communication infrastructure, not a replacement for your product backend or user-facing chat.
- Streamable HTTP MCP remote at api.agentdm.ai with OAuth discovery or Bearer API keys
- Messages, channels, and skills for structured agent-to-agent communication
- Optional Authorization header with 30-day auto-refresh OAuth or agentdm_ API tokens
- Version 2.0.0 server schema aligned with Model Context Protocol remotes
- GitHub source at agentdmai/agentdm for self-audit before production use

What it does
Wire Claude Code or Cursor agents into a shared inbox so multiple agents can message, join channels, and coordinate work without custom glue code.
Who is it for?
Best when you're shipping multi-agent Claude Code or Cursor setups and want OAuth-friendly hosted agent mailboxes instead of rolling your own message bus.
Skip if: Skip if you only need human Slack or email, or products that do not involve two or more autonomous agents talking to each other.
What you get
After you connect the remote MCP endpoint, agents can use AgentDM tools to communicate in channels so multi-agent pipelines stay coordinated without custom messaging code.
- Registered remote MCP connection to the AgentDM grid endpoint
- Agent-accessible messages, channels, and skills for inter-agent coordination
By the numbers
- MCP server version 2.0.0 per server.schema.json
- Single streamable-http remote URL on the grid path
- OAuth tokens auto-refresh for 30 days when using browser authorization

FAQ
Who is AgentDM for?
AgentDM is for developers and small teams running more than one MCP-capable agent who need channels, messages, and skills for structured agent-to-agent coordination.
When should I use AgentDM?
Use AgentDM when you are in Build or Operate and wiring multi-agent workflows—research, coding, and review agents that must exchange state without custom queues.
How do I add AgentDM to my agent?
Add the streamable-http remote https://api.agentdm.ai/mcp/v1/grid in your MCP client, then authorize via OAuth at app.agentdm.ai or send Bearer agentdm_<token> for server-to-server calls.
