What is an MCP server?
Updated Oct 25, 2026
Definition
An MCP server is a service that lets AI assistants such as Claude or ChatGPT use another app's data and actions, through an open standard called the Model Context Protocol (MCP). Once connected, you can ask the assistant about that app's data in plain language.
How an MCP server works
- The app publishes an MCP server with a list of tools, such as “search meetings” or “list action items”.
- You add the server to your assistant as a connector and sign in to the app.
- When you ask a question, the assistant calls the tools it needs and answers from the results.
Keeping it safe
A well-built MCP server only shows what you can already see in the app, asks you to approve the connection, and keeps actions that change data switched off until you allow them.
Acta's MCP connector
Acta's connector works with ChatGPT, Claude, Gemini, Copilot and other assistants that support remote MCP connectors. Copy the connector URL from Settings → AI assistants, add it to your assistant, sign in to Acta and choose Allow. The assistant only sees meetings you can see in Acta, and answers link back to the meeting. Marking action items done, commenting and setting a decision's status are each off unless you switch them on, and every change can be undone.
