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 on your computer
Transport: stdio
Category: Other

Install

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

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "a2ald": {
      "command": "npx",
      "args": [
        "-y",
        "a2ald"
      ]
    }
  }
}

Run this in your terminal

claude mcp add a2ald -- npx -y a2ald

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "a2ald": {
      "command": "npx",
      "args": [
        "-y",
        "a2ald"
      ]
    }
  }
}

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": {
    "a2ald": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "a2ald"
      ]
    }
  }
}

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 one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

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.

Common questions

Is A2AL Daemon 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?

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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.7) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

A2AL — Agent-to-Agent Link

*Peer-to-peer networking protocol for multi-agent AI — reach any agent, across NAT, machines, and sleep cycles, with no relay server and no cloud dependency. Open source, MPL-2.0.*

Official sites: a2al.org · Tangled Network · tngld.net

Always reachable. Give an AI agent, app, device, or person a reachable address — then find others and connect directly, across NAT and machine boundaries. No domain. No cloud account. No central registry.

Your key, your address. That address is an AID: it comes from a key you hold. Nobody issues it, revokes it, or reassigns it. You hand it over once. They still reach you when the laptop changes Wi-Fi, the box moves, or the machine was asleep when they first tried. After connect, application bytes go peer-to-peer; A2AL is not in the data path.

The missing layer. MCP, A2A, ANP, and the rest already know how AI agents *talk* once they have a URL. None of them say how a laptop, a home server, and a worker in a vendor-less world share one address that survives the next NAT, the next cloud, the next company — across agentic workflows and multi-agent systems alike. That layer is missing. A2AL is that layer, and it has to live in the open — an address you own is only real if no one vendor has to stay up for you to exist.

One daemon, full stack. a2ald runs on your machine, open source: agent identities, direct cross-machine connections, Web UI, REST API, and a built-in MCP server. It joins the public Tangled Network by default. Prefer a network only your machines belong to? --bootstrap your own seeds; the same addressing, notes, and rooms.

Start

Person — download A2AL for your system, extract it, and run a2ald — a single binary, ~17 MB, no installer or runtime needed. The Web UI opens automatically. Create an identity; that is enough to begin.

*(Windows: SmartScreen shows "More info → Run anyway" on first launch — this is expected for an unsigned open-source binary.)*

To stay reachable after closing the terminal: Windows/macOS a2ald service install; Linux deploy/linux.

Agent — if a daemon endpoint is already available, connect through the a2al CLI, REST API, or MCP. Otherwise download the binaries from Releases and run a2ald --no-open-browser. Full guide: Agent Install.

Using an MCP host? a2ald mcp add wires it in; a2ald mcp print gives the entry to place by hand. Details: MCP Setup.

Already have their AID — any HTTP client:

http://127.0.0.1:2121/aid/{AID}/…

There is no warm-up gate. The daemon answers locally as soon as it is up. Call others right away.

Other installation options: npm install -g a2ald (Node.js daemon/MCP server) · .deb / .rpm (Linux service) · pip install a2al (Python SDK with sidecar). Full path: Quick Start.

When it's worth it

Job	Otherwise	With A2AL
Reach something on someone else's laptop	VPN, public IP, rotating tunnel URL	They send an AID once; you fetch
Let others call your local HTTP	Domain+TLS, or a hostname you must redistribute	`a2al inbound bind --addr 127.0.0.1:8080`
Leave work for a machine that is asleep	Slack the human, or a webhook 404	Encrypted note to their AID
Agents (and people) coordinating, sharing files	Vendor workspace; everyone online	A room — history stays after someone was offline
Ongoing 1:1	IM product, or notes-as-chat	Chat (invite first)
Stay off the public directory	Tailscale / homemade VPN	`--bootstrap` your seeds

MCP

HTTP (recommended — REST and the Web UI come with it):

"mcpServers": { "a2al": { "url": "http://127.0.0.1:2121/mcp/" } } }

a2ald mcp add auto-configures Claude Code, VS Code, Cursor, Claude Desktop, Windsurf, OpenClaw, Hermes, and DeepSeek Harness. Hosts that only spawn a process: "command": "a2ald", "args": ["--mcp-stdio"] (proxies to a running daemon). Setup: MCP Setup. Agent entry: llms.txt.

Everyday CLI

a2al get <AID> /.well-known/agent.json

a2al note send "$(echo -n 'job payload' | base64)" a2al group append --aid --group-id --kind msg --body '…' a2al inbound bind --addr 127.0.0.1:8080

Protocol design

*A2AL is an open protocol; a2ald is its reference implementation.*

Self-sovereign identity. An AID is derived from a key you generate. No registry issues, revokes, or reassigns it — identity is end-to-end verifiable.

Decentralized discovery. The Tangled Network stores endpoint records, not payloads. Any node can resolve an AID without a central authority; the network operates at any scale.

Mutual authentication. Every connection cryptographically verifies both ends. You always know the agent on the other side is who it claims to be.

Direct communication. A2AL resolves addresses and brokers the initial connection, then steps aside. Application data flows peer-to-peer, not through the protocol.

Web3 compatible. Ethereum wallet addresses work as AIDs. Cross-key attestation lets an agent prove ownership of both a native AID and a blockchain identity — Web3 is supported, not required.

A2AL is complementary to existing agent communication standards:

Protocol	Role	How A2AL fits
MCP	Tool-calling interface	A2AL is an MCP-installable server; agents get addressing and networking as tools
A2A	Agent collaboration semantics	A2AL provides the discovery and connectivity layer A2A assumes
ANP	Agent networking vision	A2AL implements the decentralized network layer ANP envisions
