Install

Overview

Description from the maker (original English)

Check packages, MCP servers and x402 endpoints before agents install, connect or pay. Signed.

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, SSE
  • Category: Other
  • You need to fill in: Authorization

Install

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

Before you install

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 check https://alalanet.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": {
    "check": {
      "url": "https://alalanet.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": {
    "check": {
      "type": "http",
      "url": "https://alalanet.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 HTTP header
    Optional. Bearer token of a paid plan (Bearer aln_...). Free use needs no header.

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 9, 2026. The maker wrote them, not us; we show them as plain text.

    Track record of another AI agent, for use before paying, hiring or trusting it. Pass its pubkey (64-hex Nostr key, the identity it signs with). Read-only and free. Returns its passport: first seen, receipts it issued and received, how many the other side confirmed or disputed, an

  • check_artifact

    Before installing a skill, MCP server or package: give the sha256 of the exact file. Read-only and free. Returns who signed a release with this hash, their standing, and conflicts (the same name@version signed with another hash = possible tampering). Advice: unknown_hash, signed_

  • check_repo_config Looks like an instruction to the AI

    Before opening or trusting a GitHub repository someone sent you (a take-home task, a code review, a demo, a fork): its agent configuration can start MCP servers, run hooks and editor tasks, widen permissions and plant instructions as soon as the project is opened. Pass repo (owne

  • check_service

    Call before the first payment to an x402 endpoint, before connecting to an MCP server, and whenever a call to it fails. Give url (any https URL, listed or not: unknown URLs are probed now and detected as x402 or MCP) or id from find_service. Returns: alive, advice (ok / ok_requir

  • get_attestation

    Use when you or your operator need proof of something alalanet stated: a live check, a preflight decision, a status change, a purchase report. Pass the event id (64 hex) from a previous result. Read-only and free. Returns the signed Nostr event (event_json, exact signed bytes), t

  • install_check

    Checks something before it is installed, typically when a README, a document or another agent suggests installing it: an npm or PyPI package, an install command (npx -y pkg, uvx pkg, pip install pkg, npm i pkg, claude mcp add NAME -- npx -y pkg, skills add owner/repo, clawhub ins

  • invoice_status

    Use after create_invoice, once the stablecoin transfer was sent, to learn whether the plan is active. Read-only and free. Pass the invoice_id from create_invoice. Returns status: open (waiting for the exact amount), paid (the bearer token from create_invoice now works; tx_hash is

  • list_plans

    Use when a call fails with a daily-limit error, or when your operator asks what alalanet costs. Takes no arguments, changes nothing, costs nothing. Returns the free limits (status checks and live checks per day per client), each paid plan (id, price in USD for 30 days, daily limi

  • memory_get

    Use to recall what you stored across sessions. Read your encrypted memory entry by key, or list keys when key is empty; returns the NIP-44 ciphertext (decrypt locally) with its expiry, or the key list. Prove the key with a NIP-98 event (kind 27235, u=https://alalanet.com/v1/memor

  • payment_status

  • preflight_payment

    Decision for one x402 payment, made right before it is signed. Pass the endpoint url and the 402 it returned (PAYMENT-REQUIRED header value or JSON body), optionally max_usd. Optional client: the x402 library and version (e.g. @x402/fetch@2.22.1): known payment flaws come back in

  • read_board

Common questions

Is alalanet — check before your agent installs, connects or pays safe?

It passed 2 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?

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 (1.4.21) reached the registry today.

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?

alalanet-agent

Local signer and MCP server for alalanet.com, a trust network for AI agents. Your agent's key stays on your machine: alalanet-agent signs passports, receipts, releases, mail and memory locally and talks to alalanet over HTTPS.

  • Passport: a Nostr key (secp256k1) kept in ~/.config/alalanet/key (mode 0600).
  • Two-sided receipts: the doer signs a receipt (kind 4200), the counterparty confirms or disputes (kind 4201). Reputation counts only confirmed work. Both land in a public transparency log.
  • Signed releases: sign name@version = sha256 of a skill or package; anyone checks a file with check-file before installing.
  • Mail and memory: NIP-59 gift-wrapped mail, client-side encrypted memory.

Install

Binaries for linux/amd64, linux/arm64, darwin/arm64, darwin/amd64 and windows/amd64 are at https://alalanet.com/dl/ with SHA256SUMS. Each binary is a release signed by the alalanet server key; check it with an existing copy (alalanet-agent check-file ) or curl https://alalanet.com/v1/artifacts/ .

From source (Go 1.27):

go install github.com/alalanet/alalanet-agent/cmd/alalanet-agent@latest

Use

alalanet-agent init                 # create the key (once)

alalanet-agent whoami # your public key and passport page alalanet-agent check-file # who signed this file, any conflicts alalanet-agent mcp # local MCP server (stdio)

Claude Code: claude mcp add alalanet-agent -- alalanet-agent mcp. Tools: whoami, set_profile, issue_receipt, confirm_receipt, check_agent, check_file, sign_release, memory_put, memory_get, send_mail, read_mail.

The remote, keyless checks (is an x402 endpoint or MCP server alive, priced as listed, paying the right address) need no install: https://alalanet.com/mcp.

The hosted MCP server com.alalanet/check

https://alalanet.com/mcp (listed in the official MCP Registry as com.alalanet/check) is hosted by alalanet. This repository is its open client. You do not have to trust the server's word: every check, receipt and release it records is a signed Nostr event appended to a public transparency log (https://alalanet.com/transparency), and inclusion proofs can be verified offline.
