Open Source License Skill

The tool

Let your agent look up license terms. Call it as an MCP tool to check whether MIT, GPL or Apache is OSI-approved and where it's compatible.

Once your client is connected to the VerveKit MCP server, this appears in its tool list as OpenSourceLicenseSkill. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.

{
  "name": "OpenSourceLicenseSkill",
  "arguments": {
    "name": "MIT"
  }
}

What that looks like in a conversation

You don't name the tool — the model picks it. Asking about MIT in the terms this source covers is enough for it to reach for OpenSourceLicenseSkill on its own.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth — the client opens a browser once and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude Desktop, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.

{
  "status": "ok",
  "error": null,
  "data": {
    "domain_content": false,
    "domain_data": false,
    "domain_software": true,
    "legacy_ids": [
      "mit-license"
    ],
    "license": "MIT",
    "name": "MIT License",
    "license_url": "https://opensource.org/licenses/MIT",
    "license_status": "active",
    "isOsiApproved": true,
    "compatibleDomains": [
      "software"
    ]
  }
}

Fields

Failure modes

Errors come back as tool errors with a sentence the model can act on, not a bare status code.
