How to connect an agent (MCP server) to Claude

Agents give your AI real tools: read a web page, search, work in GitHub. Hosted ones take one address and no install. · about 3 min

1. 1

   Open the agent's How to install box

   Every agent page shows the exact line for Claude Code, the address for Claude, and a config block for Cursor. This example uses Firecrawl, which works without a key.

   
2. 2

   In Claude: Customize → Connectors → Add → Add custom connector

   Give it a name and paste the server address. Continue.

   
3. 3

   Choose how it signs in

   Claude detects it for you. If the server needs an API key (GitHub, Brave Search, Context7), add it under Request headers.

   
4. 4

   Add, then Connect

   You'll see the tools the server gives Claude. By default each one asks before it runs.

   
5. 5

   Ask for something that needs the tool

   Claude asks permission the first time. Choose Allow once until you trust it.

   
6. 6

   Check the answer used the tool

   “Used Firecrawl integration” means the answer came from the live page, not the model's memory.
