CanIUse

Can I Use MCP — browser compatibility data for HTML / CSS / JS features. Sourced from Fyrd's caniuse-db. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• feature(name) — full record for a feature by id
• search(query) — search features by title / keyword
• list_browsers() — browser ids + version tracks
• support(feature, browser, version?) — convenience: is this feature supported in this browser?

Data source

https://raw.githubusercontent.com/Fyrd/caniuse/main/data.json — cached in worker memory for 24h.

Quick Start

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

{
  "mcpServers": {
    "caniuse": {
      "url": "https://gateway.pipeworx.io/caniuse/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Caniuse data" })

The gateway picks the right tool and fills the arguments automatically.
