Signal MCP connector
Connect Claude, ChatGPT and other AI assistants to Empiraa Signal, so they can read your CRM and make changes for you.
Signal's connector lets an AI assistant, such as Claude or ChatGPT, work in Signal as the person who connected it. Ask it about your Deals, Actions, prospect contacts, Campaigns or figures, and it reads them from Signal. With View and make changes, it can also make changes for you, such as creating a Deal, logging a call or drafting an Email.
It's built on MCP (Model Context Protocol), the open standard AI assistants use to connect to business apps. Signal runs the connector as a remote MCP server, so there's nothing to install or host.

What it is#
- It works as you. It sees only what you can see in Signal, and does only what your role lets you do there.
- No API key. Each person signs in to Signal with OAuth 2.1 (PKCE) and approves the connection. The assistant app registers itself.
- Every change is previewed. Signal returns a card that says exactly what will change, from what to what. Nothing is saved until you confirm, and most changes can be undone for 7 days.
- Admins stay in control. A workspace admin decides whether assistants may be used at all, whether they may make changes, and which apps may connect.
