概览

AI 生成的概览

把非紧急的 LLM 任务排到截止时间前电网碳排放最低的时段执行，时间允许时走服务商 Batch API。

可以做什么
  • 规划与排队：在截止时间内推荐最清洁的时间窗，创建一次性或周期性任务，设置碳预算或最早开始时间。
  • 查看与管理队列：查询队列或单个任务状态及碳回执，取消单个任务、整个重复系列或全部待执行任务。
  • 调整时间：按预设或延迟推迟、更新截止时间、立即提前执行、重试失败任务。
  • 读取电网数据：获取某地区逐小时的碳排放强度预测。
  • 续接与用量：对已完成任务追加回复，读取本机订阅额度及可选的费用估算。
适用场景
适合用户说“今晚做”或“明天之前完成”而任务并不紧急的场景，可推迟到更清洁的时段执行。也适合时间灵活、又在意碳排放的周期性后台任务。
运行要求
以 stdio 方式在本机运行，通常通过 npx 启动，需要 Node.js。默认地区为 GB，其他区域需免费密钥或账号：EIA、ENTSO-E、WattTime 用户名与密码，或 Electricity Maps。通过 Anthropic 或 OpenAI 执行任务需相应 API 密钥；未配置电网密钥时使用模拟数据。需安装 tick 守护进程，排队任务才会真正执行。
安装前请注意
需要多个密钥：ANTHROPIC_API_KEY、OPENAI_API_KEY、EBB_EIA_API_KEY、EBB_ENTSOE_SECURITY_TOKEN、EBB_ELECTRICITY_MAPS_API_KEY 和 WATTTIME_PASSWORD，以及 WattTime 用户名。定时任务会消耗服务商 API 费用，用量工具可估算按标价计算的成本。任务会把结果写入文件并存入本地 SQLite 队列，还能唤醒空闲的 Claude Code 会话。README 记载了包名与变量前缀的改名，与清单所列名称不一致，安装前请确认所用版本读取的名称。

安装

在 SourceWeft 中

  1. 打开 控制台中的 ebb-ai，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

[Tidegap]

@tidegap/mcp

Renamed from @ebb-ai/mcp in 0.18.0. Use the host config key tidegap and npx -y @tidegap/mcp; the ebb-mcp bin and the EBB_* variables were removed in 0.19. See Renamed from Ebb AI.

MCP server that lets your agent run non-urgent LLM tasks at the cleanest grid hour before a deadline.

Add it to any MCP host. When a user says "do this tonight" or "by tomorrow", the agent calls schedule_task. Tidegap then runs the task at the lowest-carbon grid hour before the deadline, and through the provider Batch API when the deadline allows.

  • 12 MCP tools (measured), among them recommend_window, schedule_task, check_queue_status, get_grid_forecast, cancel_task, postpone_task, update_deadline.
  • Live 72-hour forecast. GB needs no key; other regions use free keys (EIA, ENTSO-E, WattTime, Electricity Maps).
  • One signed carbon receipt per task, stored in ~/.tidegap/queue.db.
bash
npx -y @tidegap/mcp
json
{ "mcpServers": {    "tidegap": { "command": "npx", "args": ["-y", "@tidegap/mcp"] }} }

Proof: one real GB run, 2026-09-30. Forecast peak 183 gCO2/kWh vs recommended window 88 gCO2/kWh, about 52 % lower for this run only (forecast, projected). Receipt at dispatch: 158 gCO2/kWh (measured). Host-specific configs: https://www.tidegap.com/docs#install

Run

bash
npx -y @tidegap/mcp

The server speaks MCP over stdio. To wire it into an agent client:

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json on macOS (Linux/Windows have similar paths):

json
{  "mcpServers": {    "tidegap": {      "command": "npx",      "args": ["-y", "@tidegap/mcp"],      "env": {        "TIDEGAP_ELECTRICITY_MAPS_API_KEY": "optional - mock data without it",        "TIDEGAP_DEFAULT_REGION": "US-CAL-CISO"      }    }  }}

Restart Claude Desktop after editing.

Claude Code

Add tidegap to your ~/.claude/mcp.json (or workspace .claude/mcp.json):

json
{  "mcpServers": {    "tidegap": {      "command": "npx",      "args": ["-y", "@tidegap/mcp"]    }  }}

OpenClaw

Add to ~/.openclaw/mcp.json:

json
{  "mcpServers": {    "tidegap": {      "command": "npx",      "args": ["-y", "@tidegap/mcp"]    }  }}

Tools exposed (12, measured)

ToolPurpose
schedule_task(... repeat?, every_hours?, days?, window?, time_zone?) with repeat daily, weekdays, weekly or every_n_hoursCreate a recurring job: each run is a new task at the cleanest hour of its period. End it with cancel_task(series: true).
get_grid_forecast(region, hours?)Hour-by-hour carbon intensity for a region; useful before deciding whether to defer.
recommend_window(deadline, region?, ...)Plan the cleanest window inside the deadline without queueing anything.
schedule_task(prompt, deadline, model?, region?, carbon_budget_g?, repeat?, origin_session_id?, not_before?)Queue a task to run in the cleanest window inside the deadline. Returns a task_id and one line that says whether it will run: Runs at <time> local., or the readiness sentence with its fix, for example Tasks will not run: no tick daemon. Run `tidegap install`.. not_before sets the earliest start. repeat defaults to none, also for deadline_kind: "quota_reset".
schedule_task(... runner?, cwd?, permission_profile?, result_path?, wake_session?)Hand off the work shape: runner is another name for provider; cwd is the folder a claude-code run works in (another folder than the session's runs fresh there); permission_profile is read, web or none (read with a cwd); result_path is a new file Tidegap writes the result text to, inside cwd, the session's project folder or the temp folder. wake_session: true wakes the idle Claude Code session that queued the task when it finishes (within 12 hours after its last turn; refused outside a session). runner or provider command is refused with the tidegap queue add --runner command line. output_path follows the same folder rules.
check_queue_status(task_id?)Inspect the queue or one specific task; includes a carbon receipt once the task has completed.
cancel_task(task_id, series?)Cancel a queued or scheduled task; on a repeating task, skip it, or end the series with series: true.
reply_task(task_id, text, deadline?)Continue a completed task: a new task with the conversation plus this text, same provider and model.
expedite_task(task_id)Dispatch a queued or scheduled task now, outside its carbon window.
postpone_task(task_id, preset? | until? | delay_minutes?, reset_at?)"Later": move a pending task later, never earlier. Presets 1h, tonight (22:00 to 06:00), tomorrow_morning (09:00 to 12:00), after_limit_reset (5 minutes after the Claude limit reset: reset_at, else this machine's limit reading, else a reset time given before).
update_deadline(task_id, deadline)Reschedule a task against a new deadline.
retry_task(task_id)Re-dispatch a failed task.
cancel_all(status?)Cancel every task that is still queued or scheduled.
tidegap_usage(include_spend?)Read-only: the Claude Code subscription limits of this machine and when they reset, and the Codex limits from its local logs. include_spend adds the current 5-hour window's tokens and an API list-price cost estimate.

Environment variables

These variables configure this MCP server (and the tidegap CLI, which reads the same set). They are read at the server's own entry point and injected into @tidegap/core, which is environment-pure and reads nothing ambient itself.

OpenClaw plugin users: the @vitalini/tidegap OpenClaw plugin reads no environment variables. Configure it through plugin config instead, under plugins.entries.tidegap.config in your gateway config — the "Plugin config" column below names the field that replaces each variable. OpenClaw resolves the "${ENV_VAR}" shorthand in those fields, so you can keep exporting the same variables and let the gateway read them on the plugin's behalf.

VarPlugin configPurpose
TIDEGAP_ELECTRICITY_MAPS_API_KEYelectricityMapsApiKeyAPI key from electricitymaps.com. Universal fallback. If unset (and no zone-specific feed is configured), the server falls back to deterministic mock data so you can still run the whole stack locally.
TIDEGAP_EIA_API_KEYeiaApiKeyFree US EIA key. Enables average-emissions intensity for the US ISO zones (CAISO / ERCOT / ISO-NE / NYISO / PJM / MISO).
TIDEGAP_ENTSOE_SECURITY_TOKENentsoeSecurityTokenFree ENTSO-E token. Enables EU zone intensity (FR / DE / ES / IT / NL).
WATTTIME_USERNAME + WATTTIME_PASSWORDwattTimeUsername + wattTimePasswordFree WattTime v3 account. Enables marginal-emissions (co2_moer) forecasts for the US ISO zones — takes precedence over EIA where covered, falls through to EIA on any error. The marginal signal is disclosed as signalType: "marginal" on forecasts and receipts.
TIDEGAP_DEFAULT_REGIONdefaultRegionRegion when a tool call names none. Beats the stored region setting; see Grid region.
ANTHROPIC_API_KEYanthropicApiKeyEnables the anthropic provider (batch-capable).
OPENAI_API_KEYopenaiApiKeyEnables the openai provider (batch-capable).
GEMINI_API_KEY / GOOGLE_API_KEYgeminiApiKey / googleApiKeyEnables the gemini provider (Generative Language API, sync-only). GEMINI_API_KEY is preferred; GOOGLE_API_KEY is the fallback.
OLLAMA_HOSTollamaHostEnables the local ollama provider (sync-only). Default http://localhost:11434; keyless — set this var to opt the provider in.

Grid region

The server resolves the region of each tool call in this order:

  1. the tool call's region argument,
  2. TIDEGAP_DEFAULT_REGION in the server's environment (the agent host's MCP config),
  3. the region setting stored on this machine: tidegap region set <zone>, or Settings → Grid region in tidegap ui and the Mac app (key TIDEGAP_DEFAULT_REGION in ~/.tidegap/config),
  4. a guess from the machine's time zone,
  5. GB.

The server reads the setting again when the file changes, so a new setting applies on the next tool call with no restart. A stored value that is not a supported zone is ignored, with one stderr warning per change. schedule_task replies carry region_source: flag | env | setting | timezone | fallback.

A region argument must be one of the 31 supported zones (any case). Another value is rejected with the closest zones and a link to request a region, for example Unknown zone UA. Closest: PL. Request a region: <link>. With TIDEGAP_ELECTRICITY_MAPS_API_KEY set, any zone passes, because Electricity Maps serves zones beyond the list; with TIDEGAP_ENTSOE_SECURITY_TOKEN set, IT passes too.
