Spdx License

SPDX License List MCP — canonical list of open-source software licenses with metadata and full license text. Keyless.

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

Tools

• list_licenses(osiApproved?, fsfLibre?, deprecated?) — list SPDX licenses with optional filters
• get_license(id) — metadata for a single license by SPDX identifier (e.g. MIT, Apache-2.0)
• get_license_text(id) — full license text (Markdown when available, plain text otherwise)
• search(query) — substring search across SPDX id and full name

Data source

https://raw.githubusercontent.com/spdx/license-list-data/main/json/licenses.json and the per-license json/details/<id>.json files.

Quick Start

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

{
  "mcpServers": {
    "spdx-license": {
      "url": "https://gateway.pipeworx.io/spdx-license/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 Spdx License data" })

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