delete_test_cycle

Instructions

Implementation Reference

• src/index.ts:172-184 (registration)

  The `tool` wrapper function that registers tools with the MCP server. It wraps server.registerTool with a concise signature.

  const tool = <Shape extends z.ZodRawShape>(
    name: string,
    description: string,
    inputSchema: Shape,
    // eslint-disable-next-line @typescript-eslint/no-explicit-any
    callback: (args: z.infer<z.ZodObject<Shape>>) => Promise<any>
  ) =>
    server.registerTool(
      name,
      { description, inputSchema },
      // eslint-disable-next-line @typescript-eslint/no-explicit-any
      callback as any
    );

• src/index.ts:411-419 (handler)

  The actual handler/implementation of the 'delete_test_cycle' tool. It takes an 'id' parameter, sends a DELETE request to /testcycles/{id}, and returns a success message.

  tool(
    "delete_test_cycle",
    "Permanently delete a test cycle and all its execution records. This is irreversible. Returns 204 on success.",
    { id: ID.describe("Test cycle ID") },
    async ({ id }) => {
      await qtmFetch(`/testcycles/${id}`, { method: "DELETE" });
      return ok({ message: `Test cycle ${id} deleted` });
    }
  );

• src/index.ts:414-414 (schema)

  The input schema for delete_test_cycle: an 'id' parameter (union of string or number) described as 'Test cycle ID'.

  { id: ID.describe("Test cycle ID") },

• src/index.ts:25-66 (helper)

  The qtmFetch helper function used by the delete_test_cycle handler to make the HTTP DELETE request to the QMetry API.

  async function qtmFetch(
    path: string,
    options: RequestInit = {},
    attempt = 1
  ): Promise<unknown> {
    const url = `${BASE_URL}${path}`;
    const headers: Record<string, string> = {
      apiKey: API_KEY ?? "",
      "Content-Type": "application/json",
      Accept: "application/json",
      ...(options.headers as Record<string, string> | undefined),
    };
  
    const response = await fetch(url, { ...options, headers });
  
    // Exponential back-off for rate limiting (max 3 attempts)
    if (response.status === 429 && attempt < 3) {
      const retryAfter = Number.parseInt(
        response.headers.get("Retry-After") ?? "1",
        10
      );
      const delay = Math.max(retryAfter * 1000, 1000) * attempt;
      await new Promise((r) => setTimeout(r, delay));
      return qtmFetch(path, options, attempt + 1);
    }
  
    const text = await response.text();
    let body: unknown;
    try {
      body = text ? JSON.parse(text) : null;
    } catch {
      body = text;
    }
  
    if (!response.ok) {
      throw new Error(
        `HTTP ${response.status} ${response.statusText}: ${JSON.stringify(body)}`
      );
    }
  
    return body;
  }

• src/index.ts:68-73 (helper)

  The ok helper function used to wrap the success response as MCP tool content.

  /** Wrap a successful API response as MCP tool content. */
  function ok(data: unknown) {
    return {
      content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }],
    };
  }
