Implementation Reference

• src/index.ts:163-170 (registration)

  Dynamic registration of the 'radarr_review_setup' tool in the addConfigTools function. Defines the tool name, description, and empty input schema. This object is pushed to the global TOOLS array if Radarr client is configured.
  name: `${serviceName}_review_setup`, description: `Get comprehensive configuration review for ${displayName}. Returns all settings for analysis: quality profiles, download clients, naming, storage, indexers, health warnings, and more. Use this to analyze the setup and suggest improvements.`, inputSchema: { type: "object" as const, properties: {}, required: [], }, }
• src/index.ts:176-176 (registration)

  Conditional call to addConfigTools for 'radarr', which registers the 'radarr_review_setup' tool only if RADARR_URL and RADARR_API_KEY environment variables are set.
  if (clients.radarr) addConfigTools('radarr', 'Radarr (Movies)');
• src/index.ts:166-169 (schema)

  Input schema for the radarr_review_setup tool: empty object (no parameters required). Defined inline in the tool registration.
  type: "object" as const, properties: {}, required: [], },
• src/index.ts:950-1054 (handler)

  Core handler logic for executing 'radarr_review_setup'. Uses RadarrClient to fetch status, health checks, quality profiles, root folders, download clients, naming config, media management settings, tags, and indexers. Compiles into a detailed JSON review object for setup analysis.
  case "sonarr_review_setup": case "radarr_review_setup": case "lidarr_review_setup": case "readarr_review_setup": { const serviceName = name.split('_')[0] as keyof typeof clients; const client = clients[serviceName]; if (!client) throw new Error(`${serviceName} not configured`); // Gather all configuration data const [status, health, qualityProfiles, qualityDefinitions, downloadClients, naming, mediaManagement, rootFolders, tags, indexers] = await Promise.all([ client.getStatus(), client.getHealth(), client.getQualityProfiles(), client.getQualityDefinitions(), client.getDownloadClients(), client.getNamingConfig(), client.getMediaManagement(), client.getRootFoldersDetailed(), client.getTags(), client.getIndexers(), ]); // For Lidarr/Readarr, also get metadata profiles let metadataProfiles = null; if (serviceName === 'lidarr' && clients.lidarr) { metadataProfiles = await clients.lidarr.getMetadataProfiles(); } else if (serviceName === 'readarr' && clients.readarr) { metadataProfiles = await clients.readarr.getMetadataProfiles(); } const review = { service: serviceName, version: status.version, appName: status.appName, platform: { os: status.osName, isDocker: status.isDocker, }, health: { issueCount: health.length, issues: health, }, storage: { rootFolders: rootFolders.map(f => ({ path: f.path, accessible: f.accessible, freeSpace: formatBytes(f.freeSpace), freeSpaceBytes: f.freeSpace, unmappedFolderCount: f.unmappedFolders?.length || 0, })), }, qualityProfiles: qualityProfiles.map(p => ({ id: p.id, name: p.name, upgradeAllowed: p.upgradeAllowed, cutoff: p.cutoff, allowedQualities: p.items .filter(i => i.allowed) .map(i => i.quality?.name || i.name || (i.items?.map(q => q.quality.name).join(', '))) .filter(Boolean), customFormatsWithScores: p.formatItems?.filter(f => f.score !== 0).length || 0, minFormatScore: p.minFormatScore, })), qualityDefinitions: qualityDefinitions.map(d => ({ quality: d.quality.name, minSize: d.minSize + ' MB/min', maxSize: d.maxSize === 0 ? 'unlimited' : d.maxSize + ' MB/min', preferredSize: d.preferredSize + ' MB/min', })), downloadClients: downloadClients.map(c => ({ name: c.name, type: c.implementationName, protocol: c.protocol, enabled: c.enable, priority: c.priority, })), indexers: indexers.map(i => ({ name: i.name, protocol: i.protocol, enableRss: i.enableRss, enableAutomaticSearch: i.enableAutomaticSearch, enableInteractiveSearch: i.enableInteractiveSearch, priority: i.priority, })), naming: naming, mediaManagement: { recycleBin: mediaManagement.recycleBin || 'not set', recycleBinCleanupDays: mediaManagement.recycleBinCleanupDays, downloadPropersAndRepacks: mediaManagement.downloadPropersAndRepacks, deleteEmptyFolders: mediaManagement.deleteEmptyFolders, copyUsingHardlinks: mediaManagement.copyUsingHardlinks, importExtraFiles: mediaManagement.importExtraFiles, extraFileExtensions: mediaManagement.extraFileExtensions, }, tags: tags.map(t => t.label), ...(metadataProfiles && { metadataProfiles }), }; return { content: [{ type: "text", text: JSON.stringify(review, null, 2), }], }; }
• src/index.ts:74-75 (helper)

  Initialization of RadarrClient instance required for the tool to function. Set up from RADARR_URL and RADARR_API_KEY environment variables.
  clients.radarr = new RadarrClient(config); break;
