Connect Cursor / Claude

Add InstantMCP.io as a remote MCP server. Use the public docs endpoint today; your own InstantMCP.io server URL works the same way when you ship one.

Before you start

• Confirm your client supports remote / HTTP MCP (Streamable HTTP).
• Have the MCP URL ready: either https://instantmcp.io/mcp or your hosted server URL from /app.

Cursor

Create or edit .cursor/mcp.json in your project (or your global Cursor MCP config):

{
  "mcpServers": {
    "instantmcp": {
      "url": "https://instantmcp.io/mcp"
    }
  }
}

Reload MCP servers in Cursor (Command Palette → MCP). You should see InstantMCP.io tools such as search_docs and get_pricing.

If tools do not appear:

• Check the URL (no trailing path mistakes)
• Restart Cursor after saving mcp.json
• Confirm network access to the host

Claude Desktop / Claude.ai

Add a remote MCP connector with URL:

https://instantmcp.io/mcp

Exact UI steps vary by Claude client version; look for Custom connectors or MCP servers. Authenticate if the product asks for it, then enable the InstantMCP.io tools in the conversation.

ChatGPT

Where custom MCP / actions are supported, register:

https://instantmcp.io/mcp

as a Streamable HTTP MCP endpoint. Prefer the same URL you use in Cursor so behavior stays consistent across clients.

Local development

When running this site locally:

{
  "mcpServers": {
    "instantmcp": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

Use this only for local debugging. Production clients should point at your hosted InstantMCP.io URL.

Your own InstantMCP.io server

After you create a server in /app, replace the public docs URL with your hosted endpoint. The JSON shape stays the same; only the url field changes.

Get the snippet via tool

If InstantMCP.io is already connected, call get_connect_snippet to print the JSON for Cursor or Claude. You can also ask the site assistant for a connect snippet tailored to your client.
