Looking to connect your own backend as an MCP server? See Server-Side MCP instead. This page is for connecting external MCP servers you don’t control.
What are MCP tools? MCP is an open standard that lets AI agents connect to external services. By adding an MCP server, your Crow agent gains access to all tools that server exposes—no custom code required.
- Connect a database MCP server so your agent can query customer data
- Add a CRM server so your agent can look up and update contacts
- Integrate internal APIs that already have MCP endpoints
Add a Server
- Go to Integration
- Click Add Server
- Fill in:
| Field | Description |
|---|---|
| Server Name | Friendly name (e.g., customer-api) |
| Server URL | MCP endpoint URL |
| Transport | Streamable HTTP (recommended) or SSE |
| Headers | Optional auth headers (Key: Value) |
- Click Test Connection
- Save
Managing Servers

Configuring Tools
After connecting, go to Actions to enable or disable individual tools for your agent. Only enabled tools will be available when your agent responds to users.Pre-built Integrations
