Implementation Reference
- index.ts:138-152 (registration)Registers the MCP tool 'mcp_ScancodeMCP_compare_license_compatibility' with its input schema and inline handler function that delegates to licenseCompatibilityVerdict.server.registerTool( "mcp_ScancodeMCP_compare_license_compatibility", { title: "Compare License Compatibility", description: "Legal compatibility verdict and explanation for two license types (e.g., MIT vs GPLv3).", inputSchema: { licenseA: z.string().describe("First license name (e.g., MIT, GPL-3.0)") , licenseB: z.string().describe("Second license name (e.g., Apache-2.0, GPL-2.0)") }, }, async ({ licenseA, licenseB }) => { // Use a built-in matrix for common licenses, else flag for manual review return { content: [{ type: "text", text: licenseCompatibilityVerdict(licenseA, licenseB) }] }; } );
- index.ts:143-146 (schema)Input schema defining parameters licenseA and licenseB as strings using Zod validation.inputSchema: { licenseA: z.string().describe("First license name (e.g., MIT, GPL-3.0)") , licenseB: z.string().describe("Second license name (e.g., Apache-2.0, GPL-2.0)") },
- index.ts:148-151 (handler)The handler function for the tool, which calls licenseCompatibilityVerdict and formats the response as MCP content.async ({ licenseA, licenseB }) => { // Use a built-in matrix for common licenses, else flag for manual review return { content: [{ type: "text", text: licenseCompatibilityVerdict(licenseA, licenseB) }] }; }
- index.ts:266-287 (helper)Core helper function that implements the license compatibility logic using a simple decision matrix based on license name keywords.function licenseCompatibilityVerdict(licenseA: string, licenseB: string): string { // Simple matrix for demo; real-world use would be more complex const a = licenseA.toLowerCase(); const b = licenseB.toLowerCase(); if (a === b) return `Both are ${licenseA}. Compatible.`; if ((a.includes("mit") && b.includes("gpl")) || (b.includes("mit") && a.includes("gpl"))) { return "MIT and GPL: MIT code can be included in GPL projects, but the combined work must be GPL. GPL code cannot be relicensed as MIT. Compatible with restrictions."; } if ((a.includes("mit") && b.includes("apache")) || (b.includes("mit") && a.includes("apache"))) { return "MIT and Apache: Compatible. Both are permissive, but Apache has extra patent terms."; } if ((a.includes("gpl") && b.includes("apache")) || (b.includes("gpl") && a.includes("apache"))) { return "GPL and Apache: Apache 2.0 is compatible with GPLv3, but not with GPLv2. Check versions."; } if (a.includes("proprietary") || b.includes("proprietary")) { return "Proprietary and open source: Usually incompatible. Legal review required."; } if (a.includes("unknown") || b.includes("unknown")) { return "Unknown license: Cannot determine compatibility. Legal review required."; } return "Compatibility unknown or complex. Legal review recommended."; }
