“String has been great to work with - the product is easy to manage, and the team is fast, scrappy, and a strong thought partner in helping us get to the right answer. They feel more like an extension of our data team, with the added benefit that we don't have to manage the usual fragility of scraping infrastructure ourselves.”

Reach String programmatically, through MCP, or have data delivered straight into the tools your team already uses.

Add the String Web Access API as an MCP server and let Claude, or any other agent, fetch any page on the web, live and structured. In Claude Desktop, Cursor, or any client with a config file, paste this:

claude_desktop_config.json

{
  "mcpServers": {
    "string-ai": {
      "command": "npx",
      "args": ["-y", "@usestring/mcp"],
      "env": { "STRING_AI_API_KEY": "sk_live_…" }
    }
  }
