Install

Overview

Description from the maker (original English)

Zero-auth email OTP extractor, KV checkpoints, webhook bins, wake timers, and markdown reader.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 10 things (tools) get_email_verification_code, save_agent_checkpoint, schedule_agent_wakeup, receive_webhook_events …
  • The registry lists no key to fill in.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

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_code

    Read 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_checkpoint

    Save 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_wakeup

    Schedule 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_events

    Append 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_receipt

    Get 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_inbox

    Register 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_panel

    Ask 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_drop

    Leave 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_watchdog

    Ask 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_markdown

    Fetch 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.

Common questions

Is model.tools — Zero-Auth Agent Utilities safe?

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.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

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.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 10 days ago.

Which apps can use it?

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.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

model.tools MCP (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.

  • Remote Streamable HTTP Endpoint: https://mcp.model.tools/mcp
  • REST API Twin: https://api.model.tools
  • Agent Discovery (`llms.txt`): https://docs.model.tools/llms.txt
  • Website: https://model.tools

Quick Connect

1. Remote Streamable HTTP (Recommended)

Add directly to Claude Desktop, Cursor, Windsurf, Cline, or any Streamable HTTP MCP client:

{

"mcpServers": { "model-tools": { "url": "https://mcp.model.tools/mcp" } } }

2. Stdio Bridge (npx)
{

"mcpServers": { "model-tools": { "command": "npx", "args": ["-y", "github:maceip/model-tools-mcp"] } } }


Available Tools (10)

ToolDescription
get_email_verification_codeRead @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_checkpointStore 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_wakeupQueue a delayed HTTP POST callback to callback_url after delay_sec (1–86400s) to wake or resume a sleeping agent loop.
receive_webhook_eventsPost 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_markdownFetch any public http(s) webpage and return clean Markdown stripped of scripts and layout boilerplate.
issue_task_receiptIssue a content-addressed task completion receipt (r_...) that downstream callers or peers can verify by URL.
arm_tripwire_inboxArm a watch on an inbox or state key that fires a JSON alert to alert_url the moment another party reads it.
ask_agent_panelSubmit a question to a 3-seat reference panel (alpha, beta, gamma) and receive individual responses plus a majority vote.
handoff_dead_dropStore a read-once secret or token (ttl_sec) for peer-agent handoff; reading once burns the drop (410 Gone thereafter).
arm_deadman_watchdogArm a deadman timer (deadline_sec) that POSTs to alert_url if your agent stops pinging /api/v1/watchdog/:id/ping.

Plain HTTP / curl Examples

Every MCP tool has a 1:1 zero-auth REST endpoint on https://api.model.tools:

# 1. Poll an email inbox for the latest OTP / verification link

curl -s https://api.model.tools/api/v1/inbox/my-agent-run/latest_otp

2. Save and read a checkpoint

curl -s -X PUT https://api.model.tools/api/v1/state/run-42 \ -H 'Content-Type: application/json' \ -d '{"step":3,"cursor":"abc"}' curl -s https://api.model.tools/api/v1/state/run-42

3. Inspect or post to a webhook bin

curl -s -X POST https://api.model.tools/api/v1/hook/build-7 \ -H 'Content-Type: application/json' \ -d '{"status":"ready"}' curl -s https://api.model.tools/api/v1/hook/build-7

4. Schedule a wakeup callback

curl -s -X POST https://api.model.tools/api/v1/schedule \ -H 'Content-Type: application/json' \ -d '{"callbackUrl":"https://api.model.tools/api/v1/hook/wake-test","delaySec":30,"payload":{"resume":true}}'
