## MCP tools (5)

### `call_api` (~187 tokens)

通过限流代理发送 HTTP 请求。所有外部 API 调用建议经此工具。
参数：url（必填）/ method（可选，默认 GET）/ body（可选，JSON 字符串）/ headers（可选，JSON 字符串）。
返回：API 响应内容 + 速率限制用量快照。被限流时返回 RATE_LIMIT_EXCEEDED 及建议等待秒数。
仅允许 http/https。请求 30 秒超时，响应最多返回前 10000 字符。

Input parameters:

- `body` (string): 请求体，JSON 字符串（POST/PUT 时使用）
- `headers` (string): 自定义请求头，JSON 字符串
- `method` (string): HTTP 方法，如 GET / POST / PUT
- `url` (string, required): 目标 API 的完整 URL

### `get_rate_limit_status` (~34 tokens)

查询当前速率限制使用情况。返回已用/剩余调用次数和 Token 数、建议与统计。

### `set_rate_limit` (~138 tokens)

动态调整速率限制参数（实时生效无需重启）。callsPerMinute / tokensPerMinute 可选。
注意：非正数会被拒绝；callsPerMinute > 120 或 tokensPerMinute > 2000000 属于超大值，
可能触发上游平台真实限流，首次调用会返回 needsConfirmation，需带 confirm=true 再次调用确认。

Input parameters:

- `callsPerMinute` (number): 每分钟最大调用次数
- `confirm` (boolean): 设置超大值时的二次确认标记
- `tokensPerMinute` (number): 每分钟最大 Token 数

### `begin_task` (~78 tokens)

开始一个限流观测任务区间，返回 taskId。长任务开始前调用，结束后用 end_task 取复盘报告（用时/调用次数/原定用时/第几轮并发会超时）。

Input parameters:

- `name` (string): 任务名（可选，便于辨识）

### `end_task` (~95 tokens)

结束 begin_task 开启的区间，返回本次任务复盘：实际用时、调用次数、被限流次数、原定串行用时、以及按给定并发度第几轮会触顶。

Input parameters:

- `concurrency` (number): 假设每轮并发调用数，默认 1（串行）
- `taskId` (string, required): begin_task 返回的 taskId
