📦 Installation

APIVerve is a remote MCP server — there is nothing to run locally. Point your client at the URL below and it will handle sign-in for you.

Quick setup

npx @apiverve/mcp-server

Configures VS Code and Cursor, and prints the manual step for Claude Desktop. Target one client with npx @apiverve/mcp-server cursor.

For headless setups, pass a key instead of using sign-in:

npx @apiverve/mcp-server --api-key YOUR_API_KEY

Python users can do the same with pip install apiverve-mcp then apiverve-mcp (or apiverve-mcp --api-key YOUR_API_KEY).

Manual setup

Claude Desktop — remote servers are added through the app, not a config file:

Settings → Connectors → Add custom connector → https://api.apiverve.com/v1/mcp

VS Code (mcp.json):

{
  "servers": {
    "apiverve": {
      "type": "http",
      "url": "https://api.apiverve.com/v1/mcp"
    }
  }
}

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "apiverve": {
      "url": "https://api.apiverve.com/v1/mcp"
    }
  }
}

🔑 Authentication

Two ways in — pick whichever fits:

OAuth (default, recommended) — leave the config as shown above. On first use the server returns an authorization challenge and your client walks you through sign-in. No key is stored on disk, and access can be revoked from the dashboard.

API key — add your key as a header. Useful for CI and headless environments where no browser is available:

{
  "mcpServers": {
    "apiverve": {
      "url": "https://api.apiverve.com/v1/mcp",
      "headers": { "x-api-key": "YOUR_API_KEY" }
    }
  }
}

Claude Desktop's Custom Connectors cannot send custom headers, so it is OAuth-only.

💡 Usage Examples

Once configured, use APIs naturally in conversation:

With Claude Desktop

User: What's the weather in San Francisco?
Claude: [Uses Weather API]

User: Validate this email: [email protected]
Claude: [Uses Email Validator API]

User: Convert 100 USD to EUR
Claude: [Uses Currency Converter API]

Programmatic Usage (Python)

Connect straight to the remote server — no local process involved:

from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client

url = "https://api.apiverve.com/v1/mcp"
headers = {"x-api-key": "YOUR_API_KEY"}

async with streamablehttp_client(url, headers=headers) as (read, write, _):
    async with ClientSession(read, write) as session:
        await session.initialize()

        # List available tools
        tools = await session.list_tools()

        # Call a tool
        result = await session.call_tool("emailvalidator", {
            "email": "[email protected]"
        })
