MCP Connectors
Zero ships with integrations for the tools most teams use. MCP connectors are how you add the rest yourself: connect any third-party tool that offers an MCP server and its tools become available everywhere Zero's AI works — Chat, the Run AI Agent step of Agents, and AI Properties. Create an issue in your tracker, look something up in your product database, act in whatever system you run, without waiting for anyone to build an integration for it.
Add a connector
Workspace admins add connectors in Settings → Connections → MCP Connectors.
Click Add MCP Connector.
Give it a Name and paste the MCP Server URL the tool provides.
If the server uses OAuth with its own app credentials, fill in the optional OAuth Client ID and OAuth Client Secret. Most servers do not need them.
Under OAuth Connection, click Connect Integration. The tool asks you to authorize Zero, then returns you to the settings page.
Zero reads the server's tool list and shows it under Tools with a count. The connector reads Connected when it is ready, or Error when it is not — Reconnect Integration fixes expired authorization, and Sync tools refreshes the list after the server changes. Rename and disconnect live on the same page.
Private or public
A connector belongs to whoever connected it, and only they can switch it between Private to you and Public in workspace.
Where the tools show up
Chat — open the + menu in the composer and pick the connector under MCP Connectors to enable its tools for that chat.
Agents — in a Run AI Agent step, the tools picker has an MCP Connectors group where you can allow a connector's tools, individually or all at once.
AI Properties — the Allow agent to picker has the same MCP Connectors group, so a property can be filled using data from an external tool.
Tools always appear under their connector's name, so you can see which system an action is about to touch.
