MCP Setup - ChatGrid API

Step 1: Get an API key

Go to chatgrid.ai/settings/api-keys and create a new key. It starts with cgk_live_.

Step 2: Add to your project’s `.mcp.json`

Create or edit .mcp.json in your project root:

.mcp.json

{
  "chatgrid": {
    "command": "npx",
    "args": ["chatgrid-mcp"],
    "env": {
      "CHATGRID_API_KEY": "cgk_live_your_key_here"
    }
  }
}

Add .mcp.json to your .gitignore if it contains your API key directly. Or use an environment variable reference instead.

Step 3: Restart Claude Code

Close and reopen Claude Code (or run /mcp to reload). You should see chatgrid listed as a connected MCP server.

Step 4: Try it

Talk to Claude Code naturally. It will use ChatGrid tools automatically.

Create a board

> Create a ChatGrid board for the payments project

Add content

> Add this YouTube video to the payments board: https://youtube.com/watch?v=abc123

> Add these architecture notes to the board: "We use Stripe webhooks
  verified with the signing secret. Events go through Inngest for
  reliable processing. See src/server/stripe/webhooks.ts."

Search your knowledge

> Search the payments board for webhook verification

> What does our architecture doc say about rate limiting?

Ask questions

> Based on our team's board, how should I implement retry logic
  for failed payment webhooks?

Claude Code will search your board, find relevant sources, and give you an answer grounded in your team’s actual knowledge.

What tools are available?

The MCP server gives Claude Code these capabilities:

Tips

One board per project

Keep boards focused. A “Payments” board, a “Frontend” board, an “Infrastructure” board. Don’t dump everything in one board.

Add content as you go

Found a useful Stack Overflow answer? Tell Claude Code to add it to the board. Read a good blog post? Add it. The board gets smarter over time.
