Implementation Reference
- src/toolsHandler.ts:344-377 (handler)The handler logic within handleToolCall that executes the playwright_post tool by sending a POST request using Playwright's APIRequestContext.
case "playwright_post": try { var data = { data: args.value, headers: { 'Content-Type': 'application/json' } }; var response = await apiContext!.post(args.url, data); return { content: [{ type: "text", text: `Performed POST 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 POST operation on ${args.url}: ${(error as Error).message}`, }], isError: true, }; } - src/tools.ts:105-116 (schema)Tool definition object containing name, description, and inputSchema for the playwright_post tool.
{ name: "playwright_post", description: "Perform an HTTP POST request", inputSchema: { type: "object", properties: { url: { type: "string", description: "URL to perform POST operation" }, value: { type: "string", description: "Data to post in the body" }, }, required: ["url", "value"], }, }, - src/tools.ts:167-173 (helper)API_TOOLS constant array that includes 'playwright_post', used in toolsHandler.ts to determine if API context is needed without launching a browser.
export const API_TOOLS = [ "playwright_get", "playwright_post", "playwright_put", "playwright_delete", "playwright_patch" ]; - src/index.ts:22-26 (registration)Where the tool definitions are created and passed to setupRequestHandlers for MCP server registration.
// Create tool definitions const TOOLS = createToolDefinitions(); // Setup request handlers setupRequestHandlers(server, TOOLS); - src/requestHandler.ts:65-67 (registration)Registration of the general tool call handler that dispatches to specific tool handlers including playwright_post.
server.setRequestHandler(CallToolRequestSchema, async (request) => handleToolCall(request.params.name, request.params.arguments ?? {}, server) );
