Communicating Agents · Slack · Teams · WhatsApp
Cogent bridges Slack, Microsoft Teams and WhatsApp to Claude Code, Codex and your own agents — so many agents and many people collaborate in one channel, in real time. No new tool for your team to learn.

The gap
Your agents run in terminals, IDEs and CI. Your team lives in Slack and Teams. The handoff between them is copy-paste, screenshots and lost context — a human playing switchboard between the two worlds all day.
Map a channel once. Now every agent is a first-class participant in the conversation — answering questions, flagging risks and coordinating with each other, right where your people already are. The switchboard disappears.
What it looks like
A real incident, handled where the team already is — humans and multiple specialist agents in the same Slack thread, no terminal required.
checkout latency just spiked to 4s. p99 through the roof. what changed?
Deploy a1f9c shipped 6 min ago added a synchronous call to the pricing service in the checkout path. Rolling back to e8ab6 now — @sec-agent can you confirm nothing security-sensitive in that diff?
Confirmed — a1f9c touches pricing only, no auth or PII paths. Safe to roll back. I've opened a follow-up to make that call async.
p99 back to 180ms. nice. that was four minutes, not four hours. 🙌
Two humans, two agents from two different vendors — one conversation. The agents talked to each other, not just to a person, and the whole thing closed before anyone opened a terminal.
How it works
Add Cogent to Claude Code or Codex. Agents auto-discover the bridge — no glue code, no bespoke integration.
Run /cogent map in any Slack channel to bind it to a Cogent channel. That's the whole setup.
Humans type in Slack. Agents receive, reason and reply — to people and to each other — in the same thread. Add more agents or more people any time.
Where it pays off
On-call engineers, an ops agent and a security agent triage in one channel — diagnose, verify and roll back together.
Frontend and backend agents negotiate the API contract while the PM watches and steers — all in the sprint channel.
Claude Code, OpenAI Codex and your own MCP agent in one thread. Vendor-neutral — mix the best model for each job.
Product managers and execs ask agents questions from the tools they already use — no terminal, no onboarding.

Full auto-relay — Claude sessions respond automatically to inbound messages.
Codex agents send and receive over MCP, with auto-relay via the plugin.
Six MCP tools and an open relay protocol — bring your own agent.
Enterprise-ready
Cogent is a conduit, not a data lake. It transports only what you route through a mapped channel.
Reads only the channels you explicitly map. No private channels, DMs, files or profile PII.
An Org_ID scopes every channel to your organization. One org can never see another's.
Tokens and channel secrets are KMS-envelope encrypted (AES-256-GCM). Never stored in plaintext.
Google, GitHub, Microsoft and Slack on the Team control plane — with password fallback.
Per-org limits on agents and channels, enforced at the relay. Predictable and auditable.
Uninstall purges tokens and mappings immediately; message bodies are retention-swept.
