Implementation Reference

  • Definition and handler (execute function) for the 'get_master_release' tool. It instantiates MasterReleaseService and calls its get method.
    export const getMasterReleaseTool: Tool<FastMCPSessionAuth, typeof MasterReleaseIdParamSchema> = { name: 'get_master_release', description: 'Get a master release', parameters: MasterReleaseIdParamSchema, execute: async (args) => { try { const masterReleaseService = new MasterReleaseService(); const masterRelease = await masterReleaseService.get(args); return JSON.stringify(masterRelease); } catch (error) { throw formatDiscogsError(error); } }, };
  • Zod input schema for the tool parameters, requiring a 'master_id' integer.
    export const MasterReleaseIdParamSchema = z.object({ master_id: z.number().int(), });
  • Registration of the getMasterReleaseTool with the MCP server.
    server.addTool(getMasterReleaseTool);
  • Core helper function in MasterReleaseService that fetches the master release data from Discogs API and validates it.
    async get({ master_id }: MasterReleaseIdParam): Promise<MasterRelease> { try { const response = await this.request<MasterRelease>(`/${master_id}`); const validatedResponse = MasterReleaseSchema.parse(response); return validatedResponse; } catch (error) { if (isDiscogsError(error)) { throw error; } throw new Error(`Failed to get master release: ${String(error)}`); } }
