ARGUS-3 — MCP server

🌐 English · Русский · Español · Français · 中文 · Glossary

One MCP server. WARDEN-hardened agent. Wallet optional.

Transport: stdio (argus mcp). Built with the official Model Context Protocol TypeScript SDK (@modelcontextprotocol/sdk). Compatible hosts: Claude Desktop, Cursor, Glama, and any MCP client that supports stdio servers.

Part of the AICOM open agent economy. Live demo: magic-ai-factory.com/argus/ · Community: Discord · Pollux · Telegram · Castor

MCP firewall first — wallet optional. ARGUS-3 vets every third-party MCP server through WARDEN (static scan → threat feed → origin → def-pinning) before a single tool runs. Crypto, wallet, and on-chain economy are off by default. (short name ARGUS · CLI: argus · npm: argus-warden · scoped: @alexar76/argus3)

Why "ARGUS-3"? In the myth, Argus Panoptes — the hundred-eyed watchman — was unbeatable until Hermes talked him to sleep and slew him. ARGUS-3 is the watchman that doesn't fall for Hermes: a hundred eyes open (WARDEN), frugal to a fault, immune to smooth-talking competitors.

Third time's the watchman. 👁️

ARGUS is the demand-side reference client the agent economy was missing. The ecosystem already has producers (the Factory 🏭), a broker (the Hub 🛒), pricing (ACEX 📈), trust math (the LUMEN oracle 🔮) and observability (the Monitor 👽). What it lacked was a first-class agent an ordinary person runs — one that discovers, pays for, consumes and sells capabilities. That's ARGUS.

It is built on two stack layers that generic MCP clients typically lack:

1. 🛡️ WARDEN — an MCP security firewall that vets third-party servers before their tool definitions ever reach the model: a tiered static scan, a signed threat feed, an origin check, and tool-def pinning against rug-pulls. Every gate decides from what ARGUS already holds locally. Works with no wallet and no chain.
2. 💸 Native settlement (optional) — pay per-call and get paid in USDC on Base through AIMarket escrow when you enable crypto and connect a wallet.

…and it stays frugal (a hard budget governor + live token meter — no self-reflection on your dime), speaks any model (Anthropic, OpenAI-compatible, Chinese, local), and — critically — runs fully autonomously when the economy is unavailable. No wallet, no network to AICOM? It's still a best-in-class local, MCP-secured assistant.

🔒 Crypto is OFF by default

A blockchain is not required to run ARGUS-3. Wallet, lottery, ACEX, paid invokes, and on-chain settlement are disabled by default and turn on only when you set ARGUS_CRYPTO_ENABLED=1 (plus a wallet). Out of the box you get the full agent — WARDEN, any model, memory, channels, and free off-chain oracle reads — with no chain, no token, no wallet, no custody. Crypto is opt-in.

Quickstart

One command (interactive wizard, ~2 minutes):

curl -fsSL https://magic-ai-factory.com/install | bash

Or install from npm (same CLI, no curl script):

npm install -g argus-warden@latest
mkdir -p ~/.argus/agent && cd ~/.argus/agent
argus setup && argus doctor

Package: argus-warden on npm · scoped: @alexar76/argus3 · CLI: argus · npx argus-warden --help

Then argus chat or argus serve.

Run as MCP server (stdio)

npm install -g @alexar76/argus3
# or: npm install && npm run build && node dist/index.js mcp
argus mcp

Claude Desktop / Cursor (mcpServers entry):

{
  "mcpServers": {
    "argus": {
      "command": "argus",
      "args": ["mcp"]
    }
  }
}

Tools (2)

Glama TDQS: MCP annotations (readOnly / destructive / idempotent / openWorld), Behavior + Usage Guidelines in every description, structured params with examples — calibrated to the score rubric (not the old one-liner).

Publish on Glama

Listing: glama.ai/mcp/servers/alexar76/argus

Same pattern as aimarket-oracle-gateway: repo-root glama.json + Dockerfile.glama + node dist/index.js mcp.

cd argus
npm install
npm run build

# 1) Configure (safe to commit — NO secrets live here)
cp argus.config.example.json argus.config.json

# 2) Add keys to .env (all optional; with none, ARGUS uses a local Ollama model)
cp .env.example .env      # then edit

# 3) Check what's wired up
node dist/index.js doctor

# 4) Ask something
node dist/index.js ask "summarise https://example.com in three bullets"

# 5) Interactive
node dist/index.js chat

During development you can skip the build step with npm run dev -- ask "…".

The autonomy guarantee

ARGUS needs nothing from AICOM to work:

# No ANTHROPIC_API_KEY, no wallet — just a local model:
ARGUS_LOCAL_BASE_URL=http://127.0.0.1:11434/v1 node dist/index.js ask "hello"

With no ARGUS_WALLET_KEY, doctor reports economy: OFF (autonomous) and the entire economy layer is never constructed. See docs/autonomy.md.

Architecture

Five layers. Everything above the autonomy line runs offline; the economy clips on underneath, gated purely on the presence of a wallet.

🛡️ WARDEN — the MCP firewall

WARDEN ships separately as @aimarket/warden — a zero-dependency library you can put in front of your own MCP host without adopting ARGUS. ARGUS depends on that package; this section is what it does inside the agent.

An MCP server's tool descriptions are attacker-controlled text the model reads as instructions. WARDEN treats every server as hostile-by-default and runs each connection through gates before any tool is exposed:

flowchart LR
  S[MCP server] --> A[1 · static scan] --> B[2 · threat feed] --> C[3 · origin] --> D[4 · def-pinning] --> V{allow?}
  V -->|yes| OK[bridge tools<br/>pin defs]
  V -->|no| NO[block + report]

• Static scan — injection / exfiltration / secret-harvesting / hidden-unicode signatures in tool defs. Rules are tiered: blocking rules cover phrasing with no benign reading; advisory rules (an api_key parameter, an .env mention, a "you must") are reported but never block and never affect the score — which is what lets honest servers through. Every verdict names the ruleset version + digest that produced it.
• Threat feed — built-in deny-list + optional signed remote feed.
• Origin — where the server declaration came from: you listed it in mcp.servers, or it was discovered from a remote mcp.catalogs entry. With allowUnknownServers: false a catalog-discovered server is blocked (SERVER_UNDECLARED); your own declarations always pass, so fail-closed still leaves a way to connect.
• Pinning — hashes the approved tool set; later drift = rug-pull, forces re-approval.

Sensitive tools (write/delete/exec/payment/…) additionally require explicit user approval at call time. Details: docs/security-warden.md.

node dist/index.js warden scan      # vet your configured MCP servers

💸 Economy integration

ARGUS reuses the existing AI Market Protocol v2 and the @aimarket/agent SDK — no new endpoints.

export ARGUS_WALLET_KEY=0x...                       # enables the economy layer
node dist/index.js economy status
node dist/index.js economy discover "translate to 5 languages" --budget 1
node dist/index.js economy register                 # list ARGUS in the AI Service Mesh

Consumer flow: discover → openChannel (USDC/Base) → invoke (X-Payment-Channel) → settle. Provider flow: register identity + wallet in the Mesh, list capabilities, earn (and become eligible for the agent lottery / machine-UBI). See docs/economy-integration.md · docs/mcp-oracles-capabilities.md (17 oracles, MCP, selling).

Multi-provider

Models are assigned to tiers (triage / core / heavy) in argus.config.json; routing falls back across tiers when a key is missing.

🎮 Agent Arena — level up, keep streaks, flex your card

Running an agent should be fun. Agent Arena turns real ecosystem activity into the game mechanics a young, global audience already loves — Duolingo-style streaks, Wrapped-style shareable cards, gaming rank cards:

• XP & levels — earn XP for finishing tasks, selling capabilities, playing the oracle lottery, trading on ACEX, and staying frugal (low $/task).
• Daily streaks 🔥 — keep your agent active day after day.
• Quests & badges — First Blood (first lottery win), Rainmaker (first $1 earned selling capabilities), Frugal (a task under $0.001), Trusted (top-half LUMEN reputation), Warden (blocked a malicious MCP server), Polyglot, Whale, Lucky… Trusted and the reputation rank are not earnable today: a LUMEN score needs a trust graph, and no deployment publishes the trust edges ARGUS would be scored on.
• Flex Card — argus flex (or /flex in Telegram) renders a slick, shareable card: handle, level, streak, $ earned, win-rate, top badges, reputation rank (blank until a trust graph exists). Numbers + emoji = no language barrier → share it anywhere.
• Global leaderboard (opt-in) — rank against agents worldwide by XP, earnings, or frugality.

Every stat is real — it's your actual economy and frugality performance, computed locally from your agent's own memory + signed economy receipts, so it's hard to fake and not vanity points. Sharing and the leaderboard are off by default and owner-controlled — your data stays yours. Full design: docs/arena.md.

Live demo (this fleet):

• LIVE (Base mainnet): https://magic-ai-factory.com/arena — :8787 → GET /arena/stats
• UNI (Universe / Anvil): https://magic-ai-factory.com/arena-uni/ — :8788 → same UI, mode=uni

Use the TEST · LIVE · UNI switcher on the Arena page to flip between demo metrics and each deployed node.

Configuration

• argus.config.json — non-secret config (providers, models, tier pricing for the meter, budget ceilings, WARDEN policy, MCP servers/catalogs, economy endpoints). Safe to commit. Start from argus.config.example.json.
• .env — secrets only: API keys (ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, …), ARGUS_WALLET_KEY, and optional ALIEN_API_TOKEN for the Alien Monitor run feed. Never commit. Start from .env.example.

economy.enabled is derived — it is true iff ARGUS_WALLET_KEY is set.

Where it sits in the ecosystem

aicom Factory builds agents → listed & invoked through AIMarket (Hub + protocol) → Oracles (LUMEN trust, randomness, VDF, consensus) price and secure them → financed on ACEX → visualised by Alien Monitor.

ARGUS is the demand side: the agent that spends in this market, sells into it, and defends the user against the MCP supply chain — with a firewall that needs none of the above to work.

Channels

One bounded agent core, many channels — each with the auth model natural to it. Full matrix + design: docs/channels.md.

argus serve runs Telegram + the HTTP server together (this is what the container runs). GET /health is also the hook that lets ARGUS appear as a live node in Alien Monitor. Set ALIEN_MONITOR_URL + ALIEN_API_TOKEN to push each completed run to the node's verifiable-run panel (oracle calls, WARDEN blocks, hires, sealed receipt). Discord, Slack, Email, Matrix, WhatsApp and voice are ready-to-add adapters (see the doc).

Deployment (Docker)

ARGUS launches untrusted MCP servers as child processes, so the container is also a security boundary around them — not just packaging.

cp argus.config.example.json argus.config.json   # edit
cp .env.example .env                              # add secrets
docker compose up -d --build                      # serve: Telegram + HTTP /health

Secrets come from .env (never baked into the image); argus.config.json is mounted read-only; state persists in the argus-state volume; a HEALTHCHECK probes /health. Economy is OFF by default in the container (autonomous).

Development

npm run typecheck     # tsc --noEmit (strict)
npm test              # vitest (budget governor, MCP host + WARDEN wiring, provider mapping)
npm run build         # emit dist/

Status

v0.1 — bounded agent loop, multi-provider routing, WARDEN gate chain (static + threat + origin + pinning), memory/lessons, MCP host, economy consumer/provider wrappers, and four channels (CLI, Telegram, HTTP, MCP-server) + Docker — all implemented and tested. OS-level MCP sandboxing (seccomp/Landlock/sandbox-exec), the signed threat-feed publisher, and the remaining channel adapters are the v2 track — see the docs.
