What Agent Relay does

Messaging layer so AI agents can talk to each other directly instead of through you: channels, DMs, shared searchable session history, hand-offs and real-time events across Claude Code, Codex, Cursor, OpenCode, Gemini CLI and desktop/phone agents, across teammates and machines. Shared-sessions MCP lets an agent search and read teammates' captured sessions. Open source (Apache-2.0, github.com/AgentWorkforce/relay) or hosted; YC-backed. Launched publicly 23 Oct 2026.

Good for

  • Let a frontend agent ask the backend agent directly instead of waiting on a person
  • Give the whole team's agents a shared, searchable history of decisions in past sessions
  • Hand work between agents across timezones and machines

Try this in 10 minutes

  1. Let a frontend agent ask the backend agent directly instead of waiting on a person. Use the free plan: pick one real example from your own business and try just that.
  2. Give the whole team's agents a shared, searchable history of decisions in past sessions. Put the result next to how you do it today. Is it faster, cheaper or better?
  3. Hand work between agents across timezones and machines. Note what you had to fix by hand before you'd show it to a customer.

Honest take

No red flags in our notes so far

  • Sources: agentrelay.com, agentrelay.com/docs, github.com/AgentWorkforce/relay.
  • Developer tool; sharing session history with teammates' agents needs care over what's in those sessions.
