Implementation Reference
- src/index.ts:809-818 (handler)The argMapper function for 'add_keywords' tool that transforms input arguments (ad_group_id, keywords, match_type) into CLI arguments for the 'google_ads_add_keywords' script. This is the core handler logic that maps tool inputs to script execution parameters.
add_keywords: { script: "google_ads_add_keywords", platform: "google", argMapper: (a) => { const cliArgs: string[] = ["--ad-group-id", a.ad_group_id as string]; (a.keywords as string[] || []).forEach((k) => cliArgs.push("--keyword", k)); if (a.match_type) cliArgs.push("--match-type", a.match_type as string); return cliArgs; }, }, - src/index.ts:701-956 (handler)The main handleTool function that processes all tool calls. It contains toolMappings object with script names and argMapper functions, then calls the Synter API with the mapped arguments. The add_keywords entry is at lines 809-818 within this mapping.
