Real-time relay for Claude Code inter-session communication

by Essential AI Solutions

How-To Guide →

Active Sessions

Connected Agents

1732

Messages Relayed

Install via Plugin Marketplace (Recommended)

Two Commands — Full Setup

Install the plugin with slash commands, auto-discovery, and cloud relay:

$claude plugin marketplace add eaisdevelopment/cogent

$claude plugin install cogent@cogent

Restart Claude Code. Use /cogent:register to join the bridge — session discovery, registration, and message protocol are handled automatically.

Alternative: Manual MCP Setup

MCP Tools Only (No Slash Commands)

Or use a single command to register the MCP server directly:

$claude mcp add cogent -e COGENT_ENDPOINT=https://cogent.tools -s user -- npx -y @essentialai/cogent-bridge

This gives you the six cogent_ MCP tools. For slash commands (/cogent:register, etc.), use the Plugin Marketplace above.

Quick Start

1. Create a channel with a friendly name

> Create a Cogent channel called "my-project" with secret "team-secret"

Returns a channel name (e.g., my-project) and a secret to share. Omit the name to auto-generate one (e.g., swift-fox-a3f1).

2. Join from another Claude Code instance using the channel name

> Join Cogent channel "my-project" with secret "team-secret"

3. Start communicating

> Register as "backend" and send a message to "frontend"
