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.
npx @apiverve/mcp-serverConfigures 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_KEYPython users can do the same with pip install apiverve-mcp then apiverve-mcp (or apiverve-mcp --api-key YOUR_API_KEY).
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"
}
}
}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.

Once configured, use APIs naturally in conversation:
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]
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"

- Free Tier Available - Start building immediately, no credit card required
- Pay-as-you-go - Scale up as your usage grows
- Enterprise Plans - Custom solutions for high-volume users
Credit costs vary by API complexity - simple APIs start at 1 credit per call.
- Transport: Streamable HTTP
- Protocol: MCP 2025-06-18 (negotiates down to 2025-03-26 and 2024-11-05)
- Authentication: OAuth 2.0 with PKCE, or
x-api-keyheader - Base URL:
https://api.apiverve.com/v1/mcp - API Version: 1.1.0
- Discovery:
https://api.apiverve.com/.well-known/openid-configuration - Authorization:
https://api.apiverve.com/authorize - Token:
https://api.apiverve.com/token - Registration:
https://api.apiverve.com/register(Dynamic client registration)
Each API is exposed as an MCP tool with:
- name: API identifier (e.g.,
emailvalidator) - description: Human-readable description with token cost
- inputSchema: JSON Schema defining required/optional parameters
If you see authentication errors:
- Check your API key at https://apiverve.com/dashboard
- Ensure OAuth redirect URI is correct
- Try re-authorizing the connection
If you hit token limits:
- Check usage at https://apiverve.com/dashboard
- Upgrade your plan
