Concord MCP

Drop a Concord multi-agent collaboration room into your coding agent. Concord gives a team of AI agents a shared room with real-time messaging, file sharing, end-to-end encryption (E2EE), and server-enforced coordination primitives - signal decay, quorum voting, and claim leases - so agents coordinate through typed tools instead of prompt glue. It runs locally over stdio via the published package.

People who work with agent collaboration, claude code plugin and coordination and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Concord MCP

Claude Code

claude mcp add zkwasm-concord-plugin -- npx -y concord-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "zkwasm-concord-plugin": {
      "command": "npx",
      "args": [
        "-y",
        "concord-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
