Connect an AI app

TradeCatalog runs a remote Model Context Protocol (MCP) server. Connect it to your AI app and ask things like:

• “What does Oakfield Joinery pay for 20 boxes of HX-8510?”
• “Any new orders today?”
• “Who changed Brookside’s discount, and when?”
• “Find me a zinc hex bolt, M10, and my price for it.” (as a buyer)

How it worksLink to this section#

• Staff see their workspaces: products, any customer’s prices, customers, orders and the activity log.
• Buyers see the suppliers they buy from, with their own prices and their own orders only.

Every tool call is checked with the same rules as the app. See MCP tools for what each tool does.

Claude (web, desktop and mobile)Link to this section#

1. Open Settings, then Connectors, and choose Add custom connector.
2. Name it “TradeCatalog” and paste https://tradecatalog.app/mcp.
3. Choose Connect. Sign in to TradeCatalog with your email code and choose Allow.

Connectors you add on the web also appear in Claude Desktop and the mobile apps. On Team and Enterprise plans an owner may need to add the connector for the organisation first.

claude mcp add --transport http tradecatalog https://tradecatalog.app/mcp

Then run /mcp in Claude Code and choose tradecatalog to sign in.

ChatGPTLink to this section#

1. Open Settings, then Apps & Connectors. If your plan needs it, turn on Developer mode under Advanced.
2. Create a connector with the URL https://tradecatalog.app/mcp and OAuth authentication.
3. Sign in to TradeCatalog and choose Allow.

CursorLink to this section#

Add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "tradecatalog": { "url": "https://tradecatalog.app/mcp" }
  }
}

Cursor opens the TradeCatalog sign-in page the first time you use it.

VS CodeLink to this section#

Add this to .vscode/mcp.json:

{
  "servers": {
    "tradecatalog": { "type": "http", "url": "https://tradecatalog.app/mcp" }
  }
}

Other clientsLink to this section#

Any client that supports remote MCP over Streamable HTTP with OAuth works. For clients that only run local (stdio) servers, use the mcp-remote bridge:

{
  "mcpServers": {
    "tradecatalog": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://tradecatalog.app/mcp"]
    }
  }
}

Building your own client? See OAuth for MCP clients.

Disconnect an appLink to this section#

See every AI app you’ve approved, and disconnect any of them, at tradecatalog.app/oauth/connections. Removing the connector in your AI app stops that app using it. Disconnecting here also revokes its access on our side, straight away.
