Implementation Reference

case "playwright_patch": try { var data = { data: args.value, headers: { 'Content-Type': 'application/json' } }; var response = await apiContext!.patch(args.url, data); return { content: [{ type: "text", text: `Performed PATCH Operation ${args.url} with data ${JSON.stringify(args.value, null, 2)}`, }, { type: "text", text: `Response: ${JSON.stringify(await response.json(), null, 2)}`, }, { type: "text", text: `Response code ${response.status()}` }], isError: false, }; } catch (error) { return { content: [{ type: "text", text: `Failed to perform PATCH operation on ${args.url}: ${(error as Error).message}`, }], isError: true, }; } - src/tools.ts:129-140 (schema)The input schema definition for the 'playwright_patch' tool, specifying required 'url' and 'value' parameters.
