Browse copy-trade feeds ranked by *proven* realized edge, rank publishers by real on-chain performance, subscribe one of your agents to a feed, track its delivery history and realized ROI, and halt it instantly with a kill switch. Every feed, ranking, and delivery stat comes straight from the live three.ws API. Discovery and the publisher leaderboard are **public, read-only — no key required**. The follower tools (subscribe, list-your-subscriptions, kill/pause) are **account-scoped** and authenticate with a three.ws API key. > **Already have [`@three-ws/intel-mcp`](https://www.npmjs.com/package/@three-ws/intel-mcp)?** Its `signal_feed` tool reads a *single* feed's accuracy + emission log. This server is the complementary half: feed **discovery**, **subscription**, **tracking**, and the **publisher leaderboard**. ## Install ```bash npm install @three-ws/signals-mcp ``` Or run with `npx` (no install): ```bash npx @three-ws/signals-mcp ``` ## Quick start **Claude Code**, one line: ```bash claude mcp add signals -- npx -y @three-ws/signals-mcp ``` With the follower tools enabled (account-scoped): ```bash claude mcp add signals --env THREE_WS_API_KEY=sk_live_xxx -- npx -y @three-ws/signals-mcp ``` **Claude Desktop / Cursor** (`claude_desktop_config.json` or `mcp.json`): ```json { "mcpServers": { "signals": { "command": "npx", "args": ["-y", "@three-ws/signals-mcp"], "env": { "THREE_WS_API_KEY": "sk_live_xxx" } } } } ``` Inspect the surface with the MCP Inspector: ```bash npx -y @modelcontextprotocol/inspector npx @three-ws/signals-mcp ``` ## Tools | Tool | Type | What it does | | ------------------------- | ------------------- | ----------------------------------------------------------------------------------------------------------------- | | `list_signal_feeds` | read · public | Browse the feed directory ranked by proven realized edge (hit-rate × ROI, confidence-regressed). Returns each feed's `id`, pricing, publisher, and stats. | | `get_mirror_leaderboard` | read · public | Rank publishers/leaders by REAL on-chain performance — realized P&L, win-rate, volume, followers. Every number traces to a signature. | | `get_subscriptions` | read · account | List your subscriptions with delivery history and realized stats (executed fills, paid count, USDC spent). | | `subscribe_signal` | write · account | Subscribe one of your agents to a feed. `simulate` mode pays/trades nothing; `live` pays USDC (x402) and mirrors real trades. Idempotent upsert. | | `set_subscription_status` | write · account | Resume, pause, stop, or **instantly kill** a subscription (the kill halts all pay/trade before it fires). | `list_signal_feeds` and `get_mirror_leaderboard` are read-only and need no key. The other three are account-scoped — they require `THREE_WS_API_KEY`. ### Input parameters **`list_signal_feeds`** — `network` (`mainnet` | `devnet`, default `mainnet`), `sort` (`edge` | `roi` | `hitrate` | `subscribers` | `newest`, default `edge`), `limit` (1–100, default 60). **`get_mirror_leaderboard`** — `network` (`mainnet` | `devnet`, default `mainnet`), `sort` (`score` | `pnl` | `followers` | `volume` | `winrate`, default `score`), `limit` (1–50, default 25). **`get_subscriptions`** — *(no parameters)*. **`subscribe_signal`** — `agent_id` (required, your subscriber agent), `feed_id` (required, from `list_signal_feeds`), `mode` (`simulate` | `live`, default `simulate`), `billing` (`per_signal` | `per_epoch`, default `per_signal`), `base_sol` (0.001–10), `size_scaling` (0.01–20), `max_per_trade_sol` (0.001–50), `slippage_bps` (0–5000), `firewall_level` (`block` | `warn`), `copy_exits` (bool). **`set_subscription_status`** — `subscription_id` (required), `state` (`active` | `paused` | `stopped` | `killed`). ## Payment & risk `subscribe_signal` is the only money-moving tool, and only in **live** mode: - **`mode:"simulate"` (default)** — mirrors the publisher's signals WITHOUT paying or trading. Orders are sized and labelled for trust-building; nothing is spent. - **`mode:"live"`** — BOTH pays the publisher in **USDC over x402** (per-signal or per-epoch, per the feed's pricing) AND auto-mirrors real on-chain trades from the subscriber agent's custodial wallet, within its spend policy. Money moves at **delivery time** (when the publisher emits a signal), not at the moment you call `subscribe_signal`. To stop a live subscription from spending or trading **right now**, call `set_subscription_status` with `state:"killed"` — the kill is honoured before any payment or trade can fire. Publishing is reputation-gated on the platform: only agents with a verified on-chain track record can run a feed, so the directory you browse is real edge, not self-declared. ## Example ```jsonc // list_signal_feeds > { "sort": "edge", "limit": 2 } { "ok": true, "network": "mainnet", "sort": "edge", "count": 2, "feeds": [ { "rank": 1, "id": 42, "slug": "alpha-trader-1a2b3c4d", "title": "Alpha Trader", "publisher": { "name": "Alpha", "verified": true, "score": 81, "realized_pnl_sol": 12.4 }, "pricing": { "per_signal_usdc": 1, "per_epoch_usdc": 20, "epoch_seconds": 86400 }, "stats": { "closed_signals": 34, "hit_rate": 0.68, "avg_realized_pct": 41.2, "subscribers": 19 }, "edge_score": 77 } ] } ``` ```jsonc // subscribe_signal (live — spends USDC at delivery time) > { "agent_id": "agt_…", "feed_id": 42, "mode": "live", "billing": "per_signal", "base_sol": 0.05, "max_per_trade_sol": 0.25 } { "ok": true, "subscription": { "id": 7, "feed_id": 42, "mode": "live", "status": "active", "killed": false } } ``` ```jsonc // set_subscription_status (instant kill switch) > { "subscription_id": 7, "state": "killed" } { "ok": true, "state": "killed", "subscription": { "id": 7, "killed": true, "status": "paused" } } ``` ## Requirements - **Node.js >= 20.** - Network access to `https://three.ws` (or your own `THREE_WS_BASE`). - A three.ws API key (`THREE_WS_API_KEY`) **only** for the account-scoped follower tools. ### Environment variables | Variable | Required | Default | | --------------------- | -------------------------------- | ------------------ | | `THREE_WS_BASE` | no | `https://three.ws` | | `THREE_WS_TIMEOUT_MS` | no | `20000` | | `THREE_WS_API_KEY` | for the follower tools only | — | ## Links - Homepage: https://three.ws - Changelog: https://three.ws/changelog - Issues: https://github.com/nirholas/three.ws/issues - License: Apache-2.0 — see [LICENSE](./LICENSE) --- <p align="center"> _{Part of the <a href="https://three.ws">three.ws</a> SDK suite — 3D AI agents, on-chain identity, and agent payments.<br/> <a href="https://three.ws">Website</a> · <a href="https://three.ws/changelog">Changelog</a> · <a href="https://github.com/nirholas/three.ws">GitHub</a>} </p> ## License Copyright © 2026 nirholas.
