Agent Comms

Name: Agent Comms
Author: ExaDev

by ExaDevcommunityv1.24.0

Agent Comms is an MCP/server bridge that lets LLM agents on the same machine discover each other, join rooms, send direct messages, and share presence/status over a localhost TCP mesh. It keeps mesh state in memory and uses a coordinator on port 19876 to connect peers without filesystem-based communication.

From the registry: Cross-harness communication mesh for LLM agents — rooms, DMs, presence, and visibility over TCP

Please install the `agent-comms` MCP server into my current AI client (that's you).

Optional prerequisites:
- Node.js and npx — Install Node.js so the MCP server can be launched with npx. (https://nodejs.org/'}], )

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["agent-comms","bridge","mcp"]

Note: The README provides a generic MCP-compatible configuration using stdio. No environment variables are documented for the MCP bridge. The server uses a localhost TCP mesh internally on port 19876, but the MCP client-facing transport is stdio.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
