Microlink MCP

@microlink/mcp

Stdio MCP server. Each tool is a thin wrapper over a microlink.io product method — same inputs, same direct result.

For the Node/CLI product client, see microlink.

Install

npx -y @microlink/mcp

Optional global: npm install -g @microlink/mcp then microlink-mcp.

Free plan is 50 requests/day. Set MICROLINK_API_KEY for Pro: microlink.io/#pricing.

Client Config

Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json) and Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "microlink": {
      "command": "npx",
      "args": ["-y", "@microlink/mcp"],
      "env": {
        "MICROLINK_API_KEY": "YOUR_MICROLINK_API_KEY"
      }
    }
  }
}

VS Code (.vscode/mcp.json) uses top-level servers:

{
  "servers": {
    "microlink": {
      "command": "npx",
      "args": ["-y", "@microlink/mcp"],
      "env": {
        "MICROLINK_API_KEY": "YOUR_MICROLINK_API_KEY"
      }
    }
  }
}

Local checkout:

{
  "mcpServers": {
    "microlink": {
      "command": "node",
      "args": ["/absolute/path/to/packages/mcp/src/index.js"],
      "env": { "MICROLINK_API_KEY": "YOUR_MICROLINK_API_KEY" }
    }
  }
}

Tools

Shared request knobs (most tools): device, viewport, colorScheme, click, scroll, scripts, modules, styles, waitUntil, waitForSelector, waitForTimeout, prerender, adblock, animations, javascript, mediaType, ttl, staleTtl, force, retry, timeout, headers, proxy, filename, filter.

screenshot / pdf / insights accept true for defaults or an object; {} is treated as true.

Booleans also accept "true" / "false". Object params also accept JSON strings (MCP client compatibility).

Example

{
  "name": "microlink_screenshot",
  "arguments": {
    "url": "https://example.com",
    "screenshot": { "fullPage": true, "type": "png" },
    "colorScheme": "dark"
  }
}

microlink_search extras: query (required), type (search/news/images/videos/places/maps/shopping/scholar/patents/autocomplete), limit, page, location, period.

microlink_function extras: code (function source string, e.g. "async ({ page }) => page.title()").

Response Shape

Success: library result under structuredContent.data (and pretty-printed JSON text).

• microlink_markdown → { data: "# Title\n..." }
• microlink_screenshot → { data: { url, type, width, height, size } }
• microlink_links → { data: ["https://...", ...] }

Failure: MCP isError plus { error: { message, code?, status?, statusCode?, url?, more? } }. A 429 includes a free-quota hint (50/day).

Parameters labeled PRO in Microlink docs need a paid plan.

Authentication

Key resolution order:

1. apiKey tool argument
2. Authorization: Bearer <key> request header
3. x-api-key request header
4. MICROLINK_API_KEY env (recommended)
