ContextWire MCP Server

A Model Context Protocol server that gives AI agents access to web search across 105 engines, academic research, content extraction, and more.

94.3% accuracy on SimpleQA benchmark.

Quick Setup

Add to your MCP client config (Claude Desktop, Claude Code, Cursor, etc.):

{
  "mcpServers": {
    "contextwire": {
      "url": "https://contextwire.dev/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

No local server needed — it's a hosted MCP endpoint.

Node.js usage

The advertised @contextwire/sdk package is not currently available on the public npm registry, and its repository is private. Use the HTTP API directly:

const url = new URL('https://contextwire.dev/api/ask');
url.searchParams.set('q', 'Who invented the transistor?');
const response = await fetch(url, {
  headers: { Authorization: `Bearer ${process.env.CONTEXTWIRE_API_KEY}` }
});
if (!response.ok) throw new Error(`ContextWire HTTP ${response.status}`);
console.log(await response.json());

Requires Node.js with built-in fetch and a ContextWire API key.
