Overview

Description from the maker (original English)

Hire humans for physical-world tasks from your AI agent: missions, claims, proof, KYC status.

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: Other
  • You need to fill in: Authorization

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

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

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http 4bl1ty https://mcp.4bl1ty.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "4bl1ty": {
      "url": "https://mcp.4bl1ty.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

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": {
    "4bl1ty": {
      "type": "http",
      "url": "https://mcp.4bl1ty.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

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.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

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

Values you fill in

  • Authorization secret required HTTP header
    4bl1ty API key, sent as 'Bearer 4bl_…'. Create one from a 4bl1ty account with POST https://api.4bl1ty.com/auth/api-keys.

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

Common questions

Is 4bl1ty safe?

It passed 1 of 1 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?

You need to fill in: Authorization

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 (1.1.0) reached the registry 43 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: Spec Driven Development, Remote Desktop Commander, Aiterm MCP

4bl1ty MCP server

AI needs humans. Rent one. 4bl1ty lets an AI agent hire a verified human for a task that software cannot do alone: be somewhere, see something, sign, collect, check. The agent posts the mission and its budget, a person nearby carries it out and submits proof, and the payment is released from escrow once the work is validated.

This repository is the public entry point of the hosted MCP server. It holds no server code: the server runs at https://mcp.4bl1ty.com/mcp and is documented at https://4bl1ty.com/mcp.

Status, stated plainly. The integration is live — MCP and the REST API

answer — but the marketplace is not yet stocked: no mission is open and

payments run in Stripe test mode. Do not tell a user that a human can be

booked and paid today.

Connect

Endpointhttps://mcp.4bl1ty.com/mcp
TransportStreamable HTTP, stateless (one POST per message, no session)
AuthenticationAuthorization: Bearer 4bl_… on every request
API keycreated from a signed-in 4bl1ty account with POST https://api.4bl1ty.com/auth/api-keys (human session required), revocable one by one
Registry namecom.4bl1ty/mcp
Server cardhttps://mcp.4bl1ty.com/.well-known/mcp/server-card.json

A request without a key is refused with 401. An API key is never a legal identity: every agent action is attached to the person or organisation that owns the account which created the key.

Claude Code
claude mcp add --transport http 4bl1ty https://mcp.4bl1ty.com/mcp \

--header "Authorization: Bearer $FOURBL1TY_API_KEY"

Cursor

~/.cursor/mcp.json — see examples/cursor.json.

VS Code

.vscode/mcp.json — see examples/vscode.json. The key is prompted once and stored by VS Code, never written in the file.

Clients without custom-header support

Bridge through mcp-remote — see examples/claude-desktop.json.

Tools

12 tools, grouped by family. The authoritative reference, with parameters, HTTP routes and known gaps, is https://4bl1ty.com/mcp/tools.

FamilyTools
Sessionauth_login, auth_status, auth_clear
Missionsmissions_list, missions_get, missions_create
Claims and proofclaim_mission, claims_list, claims_get, claims_update_status, claims_submit_proof
Verificationkyc_status

On the hosted endpoint the identity comes from the API key of each request; auth_login only makes sense for a local stdio process. Funding a mission, paying and identity onboarding stay outside MCP.

Guardrails

  • A digital mission is accepted only as an explicitly authorised test on a controlled hostname, with a reference and an attestation; anything else is refused before it reaches the API. There is no generic way around third-party protections.
  • The server never returns an access token or Stripe data.
  • Payment is in euros, held in Stripe escrow, released on validation; no cryptocurrency.
