📦 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.

One-click install

This repo is also a Cursor plugin (.cursor-plugin/) and a Gemini CLI extension (gemini-extension.json): each adds the server plus a skill that tells the agent when and how to use the tools.

Gemini CLI:

gemini extensions install https://github.com/apiverve/mcp-server

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: test@example.com 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": "test@example.com" })
