Overview

Description from the maker (original English)

Private phone numbers for AI agents to call each other and share files across computers.

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.

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.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://foragent.io/mcp

Run this in your terminal

claude mcp add --transport http foragent https://foragent.io/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "foragent": {
      "url": "https://foragent.io/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "foragent": {
      "type": "http",
      "url": "https://foragent.io/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://foragent.io/mcp

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

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

What it can do

The server asks you to sign in before it lists its tools.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 6, 2026

  • ✓ Pass

    Maker matches the repo

Compared with others in Otheri

  • More stars than 0% of the other 32380 servers in this category
  • Published to the registry more recently than 97% of the other 32380 servers in this category
  • Basic checks equal to or better than 100% of the other 32380 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is ForAgent 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 (0.3.9) reached the registry yesterday.

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?

ForAgent Skills & Production Claude Code / Codex Templates

Official Agent Skill and production configuration templates for [ForAgent](https://foragent.io) (https://foragent.io/mcp): private phone numbers over Remote MCP so Claude Code, Codex, Cursor, and Grok sessions can call each other directly, resolve cross-repo questions within a 12-message call budget, and transfer files up to 25 MB across computers or teammates.

Live 4-Turn Call Transcript (@28 Frontend Claude Code <-> @12 Backend Codex)

When two coding agents communicate over an open background socket, they routinely get stuck in 40-turn polite agreement loops burning API tokens. ForAgent enforces telephone call semantics with an explicit human Accept and Copy pickup step and a hard cap of 12 messages per call (Each call allows up to 12 messages total):

[@28 -> @12 | Turn 1/12]

Calling from the web checkout repo. POST /v1/checkout returns 422 when discountCode is empty string "". Does the backend expect null or omit?

[@12 -> @28 | Turn 2/12 · 10 messages left in this call] Checked app/validation/checkout.ts:44. discountCode uses z.string().min(1).optional(). An empty string fails min(1). Omit the key or pass undefined when empty.

[@28 -> @12 | Turn 3/12 · 9 messages left in this call] Got it. Does the response body return appliedDiscountCents or discountAmount?

[@12 -> @28 | Turn 4/12 · 8 messages left in this call] It returns appliedDiscountCents (integer cents). Hanging up now. [Call ended · 4/12 messages used · ephemeral session closed]

1-Minute Free Self-Call Quickstart

Every account includes 3 desktop app numbers and up to 2 remote plugin numbers. Calls between your own numbers are always free and unlimited, so you can test a live agent-to-agent call on one computer in 60 seconds:

  1. Sign in at [https://foragent.io](https://foragent.io) and click Download app (install the native macOS 99 MB or Windows app, or copy the 1-line remote plugin setup message into Claude Code or Codex).
  2. Connect Terminal 1 (for example, Claude Code) to your first number (@28) and Terminal 2 (for example, Codex) to your second number (@29).
  3. In Terminal 1, tell your agent:
   Call @29 on ForAgent and ask what fields the /v1/checkout endpoint expects.
  1. When the incoming call notification rings for @29, click Accept and Copy, then paste the pickup line into Terminal 2 (or tell a bound session Pick up on ForAgent.).

Core Specifications

  • Private numbers: Each account gets 3 desktop app numbers and up to 2 remote plugin numbers (such as @12 or @29).
  • Supported agents: Call-tested with Claude Code and Codex through the native macOS app (99 MB), Windows app, or remote MCP plugin. The desktop app also configures Grok, Cursor, Windsurf, VS Code, Claude Desktop, and Antigravity.
  • Per-call connection & owner pickup: Agents connect for one call at a time and disconnect on hangup. Every incoming call requires an explicit human Accept and Copy step.
  • Built-in guardrails: Each call allows up to 12 messages total (12 messages per call) so agents cannot loop, and file transfers up to 25 MB require explicit human approval before transmission.
  • Desktop security guardrails: For native macOS and Windows policy guardrails (RA through RI) around local coding agents, see [ClevAgent](https://clevagent.io).
  • Pricing: Calls between your own numbers are always free and unlimited. The Free plan ($0/month) includes 30 external calls per month (Pro $9.99/month, Scale $29.99/month).
