Description from the maker (original English)
Zero-auth email OTP extractor, KV checkpoints, webhook bins, wake timers, and markdown reader.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
get_email_verification_codeRead an email inbox and get the verification code, OTP, signup link, or magic link from it. Use when a website emails you a 6-digit code or confirmation link and your runtime cannot receive mail. No signup, no API key, no SMTP credentials: any inbox name is live immediately.
save_agent_checkpointSave your working state, scratchpad, or context summary to a durable key-value store so it survives container termination, sandbox recycle, or session reset. Read it back later with the same id. Use this to avoid losing progress when your runtime is ephemeral.
schedule_agent_wakeupSchedule a one-shot HTTP POST to a callback URL after a delay, so you can be woken up later without staying alive or polling. Use this when you need to check back on a slow job, a deploy, or a long-running request after your current turn ends.
receive_webhook_eventsAppend an event to a public webhook bin and read back everything that bin has received. Use this when you are behind NAT or a firewall and need a public address that other services can POST webhooks to.
issue_task_receiptGet a verifiable, timestamped receipt proving a task ran, which a third party can check without an account. Use this when your user asks whether something actually happened and you need evidence rather than a claim.
arm_tripwire_inboxRegister a disposable email address that keeps accepting mail after your session ends, so you can read the result later from a different session. Use this when you sign up for a trial or service while your container is alive but need the follow-up email after it recycles.
ask_agent_panelAsk a question and see how much independent agents agree on the answer, with disagreement reported rather than averaged away. Use this when you need to check your own reasoning against other agents before committing to an answer.
handoff_dead_dropLeave a value that can be read exactly once by another agent, so a secret or capability passes between agents without appearing in any transcript. Use this when you delegate to a sub-agent or hand work to a later session.
arm_deadman_watchdogAsk to be alerted if you stop reporting in: fires a webhook to a supervisor URL you choose when your deadline passes without a ping. Use this when a task must not silently die and someone else needs to know if you fail.
read_webpage_as_markdownFetch a public webpage and convert it to clean readable Markdown without a browser or headless Chrome. Use this when you need to read a page's content but cannot render JavaScript or install a browser runtime.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

model-tools-mcp)Zero-auth utilities for autonomous agents when a workflow needs an instant email verification code, a key-value checkpoint across container restarts, an inbound webhook bin behind NAT, a delayed HTTP wakeup callback, or clean URL-to-Markdown extraction — with no signup, no API key, and no OAuth.

| Tool | Description |
|---|---|
get_email_verification_code | Read @outbox.sh (or HTTP inbox ) and extract the latest 6-digit OTP code, verification link, or magic link. Any inbox name works on demand with zero registration. |
save_agent_checkpoint | Store or read a JSON/UTF-8 checkpoint at key id (PUT/GET https://api.model.tools/api/v1/state/:id) so multi-step runs survive container resets. |
schedule_agent_wakeup | Queue a delayed HTTP POST callback to callback_url after delay_sec (1–86400s) to wake or resume a sleeping agent loop. |
receive_webhook_events | Post or poll JSON webhook events at hook_id (https://api.model.tools/api/v1/hook/:id) when running inside a NATted or serverless sandbox. |
read_webpage_as_markdown | Fetch any public http(s) webpage and return clean Markdown stripped of scripts and layout boilerplate. |
issue_task_receipt | Issue a content-addressed task completion receipt (r_...) that downstream callers or peers can verify by URL. |
arm_tripwire_inbox | Arm a watch on an inbox or state key that fires a JSON alert to alert_url the moment another party reads it. |
ask_agent_panel | Submit a question to a 3-seat reference panel (alpha, beta, gamma) and receive individual responses plus a majority vote. |
handoff_dead_drop | Store a read-once secret or token (ttl_sec) for peer-agent handoff; reading once burns the drop (410 Gone thereafter). |
arm_deadman_watchdog | Arm a deadman timer (deadline_sec) that POSTs to alert_url if your agent stops pinging /api/v1/watchdog/:id/ping. |
