Overview

Description from the maker (original English)

Manage copy-trade follows — follow leaders, tune sizing and guard rules, and track fees owed.

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 on your computer
  • Transport: stdio
  • Category: Accounting, finance & tax
  • You need to fill in: THREE_WS_API_KEY

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).
  • You fill in yourself: THREE_WS_API_KEY, THREE_WS_BASE, THREE_WS_TIMEOUT_MS

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

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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": {
    "copy": {
      "command": "npx",
      "args": [
        "-y",
        "@three-ws/copy-mcp"
      ],
      "env": {
        "THREE_WS_API_KEY": "your-value",
        "THREE_WS_BASE": "your-value",
        "THREE_WS_TIMEOUT_MS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add copy --env THREE_WS_API_KEY=your-value --env THREE_WS_BASE=your-value --env THREE_WS_TIMEOUT_MS=your-value -- npx -y @three-ws/copy-mcp

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": {
    "copy": {
      "command": "npx",
      "args": [
        "-y",
        "@three-ws/copy-mcp"
      ],
      "env": {
        "THREE_WS_API_KEY": "your-value",
        "THREE_WS_BASE": "your-value",
        "THREE_WS_TIMEOUT_MS": "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": {
    "copy": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@three-ws/copy-mcp"
      ],
      "env": {
        "THREE_WS_API_KEY": "your-value",
        "THREE_WS_BASE": "your-value",
        "THREE_WS_TIMEOUT_MS": "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 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.

Values you fill in

  • THREE_WS_API_KEY secret required env
    Your three.ws bearer credential: an API key (sk_live_… / sk_test_…) or OAuth access token. Every copy-trade subscription, intent, and fee is scoped to the account it identifies. Required for all tool…
  • THREE_WS_BASE env
    Base URL of the three.ws API that serves the copy-trading endpoints. Override only when self-hosting or targeting a preview deployment.
  • THREE_WS_TIMEOUT_MS env
    Per-request timeout in milliseconds for the live copy-trading reads and writes.

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

Common questions

Is three.ws Copy Trading 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: THREE_WS_API_KEY

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 (0.1.4) reached the registry 27 days 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?

@three-ws/copy-mcp

Drive your three.ws copy-trading from any AI agent — follow leaders, tune sizing & guard rules, work the copy-intent inbox, and track fees owed. Headless, non-custodial.


A Model Context Protocol server that turns the three.ws copy-trading control surface — follow/unfollow leaders, tune guard rules, read your copy-intent inbox, and see fees owed — into agent-drivable tools over stdio. Everything the website's copy dashboard does, headless.

Non-custodial by design. three.ws never signs a transaction or holds your funds. When a leader you follow trades, the engine produces a sized, guard-checked copy INTENT that you (or your agent) act on from your own wallet. Every order is clamped to your per-trade cap and your remaining daily budget, so a runaway leader can never drain you. Performance fees settle in $THREE.

Install

npm install @three-ws/copy-mcp

Or run with npx (no install):

npx @three-ws/copy-mcp

Quick start

Copy trading is account-scoped, so set THREE_WS_API_KEY to a three.ws API key (sk_live_… / sk_test_…) or OAuth access token. Mint one at three.ws/dashboard/developers.

Claude Code, one line:

claude mcp add copy --env THREE_WS_API_KEY=sk_live_xxx -- npx -y @three-ws/copy-mcp

Claude Desktop / Cursor (claude_desktop_config.json or mcp.json):

{

"mcpServers": { "copy": { "command": "npx", "args": ["-y", "@three-ws/copy-mcp"], "env": { "THREE_WS_API_KEY": "sk_live_xxx" } } } }

Inspect the surface with the MCP Inspector:

THREE_WS_API_KEY=sk_live_xxx npx -y @modelcontextprotocol/inspector npx @three-ws/copy-mcp

Discovery (which leaders to follow) lives in @three-ws/intel-mcp → copy_smart_wallets. This server manages the follows you commit to.

Tools

ToolTypeWhat it does
list_subscriptionsread-onlyEvery leader you follow — status, sizing rule, full guard-rule set, perf fee, and live pending/acted counts.
create_subscriptionwrite (idempotent)Follow a leader / re-tune the follow. Defines how their trades size into your wallet. Upserts per leader.
update_subscriptionwrite (idempotent)Pause / resume / stop a follow, or change its sizing & guard rules. Patch by id — only the fields you pass.
cancel_subscriptionwrite (destructive)Soft-stop a follow: no more intents, history preserved. Re-follow later with create_subscription.
get_executionsread-onlyYour copy-intent inbox + history — coin, direction, sized order, skip reason, status, recorded fill.
record_executionwriteMark a pending intent acted (optionally with your fill signature) or dismissed. Never signs for you.
get_earningsread-onlyYour fees owed across the leaders you copy — or, with agent_id, a leader's public aggregate earnings.

All reads return live data (counts, intents, and accruals move between calls), so none are idempotent.

Input parameters

`list_subscriptions` — none.

`create_subscription` — leader_agent_id (required, UUID), copier_wallet (required, base58), network (mainnet | devnet, default mainnet), sizing_rule (fixed | multiplier | pct_balance, default fixed), fixed_sol (required for fixed sizing), multiplier (default 0.1), pct_balance (0–100), per_trade_cap_sol (default 0.5), min_order_sol (default 0.02), daily_budget_sol (default 1), max_open_copies (1–100, default 5), mcap_floor_usd, mcap_ceiling_usd, copy_sells (default true), require_safety_pass (default false), min_oracle_score (0–100), perf_fee_bps (0–3000, default 1000), telegram_chat_id.

`update_subscription` — id (required, UUID) plus any of: status (active | paused | stopped), and the sizing/guard fields from create_subscription (each optional; pass null to clear mcap_floor_usd / mcap_ceiling_usd / min_oracle_score / telegram_chat_id). Only the fields you pass change. leader_agent_id and network cannot be changed here: they identify the subscription, so re-pointing them means creating a new follow with create_subscription.

`cancel_subscription` — id (required, UUID).

`get_executions` — status (pending | acted | dismissed | skipped | expired | all, default pending), limit (1–100, default 50).

`record_execution` — id (required, UUID), action (acted | dismissed), tx_signature (optional, recorded only when acted).

`get_earnings` — agent_id (optional UUID — provide for a leader's public aggregate; omit for your own rollup), network (mainnet | devnet, default mainnet).

Example

// create_subscription — follow a leader, 0.05 SOL per copy, capped, safety-gated

{

"leader_agent_id": "8f3c…-uuid", "copier_wallet": "7Np…YourWallet", "sizing_rule": "fixed", "fixed_sol": 0.05, "per_trade_cap_sol": 0.1, "daily_budget_sol": 0.5, "mcap_floor_usd": 50000, "require_safety_pass": true } { "ok": true, "subscription": { "id": "…", "status": "active", "network": "mainnet", // the create/update responses return the raw subscription row, so leader // name/image are null here; list_subscriptions joins the leader profile // and also adds pending_count / acted_count per row "leader": { "agent_id": "8f3c…", "name": null, "image": null, "wallet": null }, "copier_wallet": "7Np…YourWallet", "sizing": { "rule": "fixed", "fixed_sol": 0.05, "multiplier": 0.1, "pct_balance": 0 }, "guards": { "per_trade_cap_sol": 0.1, "min_order_sol": 0.02, "daily_budget_sol": 0.5, "max_open_copies": 5, "mcap_floor_usd": 50000, "mcap_ceiling_usd": null, "copy_sells": true, "require_safety_pass": true, "min_oracle_score": null }, "perf_fee_bps": 1000 } }

// get_executions — the actionable inbox

{ "status": "pending", "limit": 5 }

{ "ok": true, "status": "pending", "count": 1, "executions": [ { "id": "…", "status": "pending", "leader": { "name": "…" }, "coin": { "mint": "…", "symbol": "…", "name": "…" }, "direction": "buy", "planned_sol": 0.05, "expires_at": "…" } ] }

// record_execution — you bought it yourself; log the fill

{ "id": "…", "action": "acted", "tx_signature": "5xQ…" }

{ "ok": true, "execution": { "id": "…", "status": "acted", "tx_signature": "5xQ…" } }

Requirements

  • Node.js >= 20.
  • A three.ws account credential in THREE_WS_API_KEY (all tools except a leader's public aggregate earnings).
  • Network access to https://three.ws (or your own THREE_WS_BASE).
Environment variables
VariableRequiredDefaultNotes
THREE_WS_API_KEYall tools except get_earnings with agent_id—API key (sk_live_…) or OAuth token. Treat like cash.

Errors

A failed tool call returns an MCP error result (isError: true) whose text is a single JSON object: { "ok": false, "error": " ", "message": "…" }, plus status on upstream rejections:

errorMeaningRecovery
missing_credentialThe tool needs auth and THREE_WS_API_KEY is unset. Thrown before any request is sent.Set the key.
validation_errorBad arguments caught client-side, e.g. sizing_rule: "fixed" without a positive fixed_sol.Fix the call.
no_changesupdate_subscription was called with only an id.Pass at least one field to change.
not_foundupdate_subscription was given an id that is not one of your subscriptions.Check list_subscriptions.
upstream_errorThe API rejected the request; status carries the HTTP code (400 bad fields, 401 bad/expired credential, 404 no such subscription on cancel_subscription, 409 no such pending intent on record_execution, 429 rate-limited).Act on the message and status.
timeoutNo response within THREE_WS_TIMEOUT_MS.Retry or raise the timeout.
network_errorThe request never reached the API (DNS, offline, TLS).Check connectivity / THREE_WS_BASE.
bad_configTHREE_WS_TIMEOUT_MS is not a positive number. Thrown while the server starts (module load), so the process exits before serving.Fix the env var.
