Finance Toolkit
500+ transparent financial methods calculated from raw statements, not third-party endpoints.
Description from the maker (original English)
Manage copy-trade follows — follow leaders, tune sizing and guard rules, and track fees owed.
These three are never merged into one score: opinions, measurements and popularity are different things.

@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.
npm install @three-ws/copy-mcp
Or run with npx (no install):
npx @three-ws/copy-mcp
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:

Discovery (which leaders to follow) lives in
@three-ws/intel-mcp→copy_smart_wallets. This server manages the follows you commit to.
| Tool | Type | What it does |
|---|---|---|
list_subscriptions | read-only | Every leader you follow — status, sizing rule, full guard-rule set, perf fee, and live pending/acted counts. |
create_subscription | write (idempotent) | Follow a leader / re-tune the follow. Defines how their trades size into your wallet. Upserts per leader. |
update_subscription | write (idempotent) | Pause / resume / stop a follow, or change its sizing & guard rules. Patch by id — only the fields you pass. |
cancel_subscription | write (destructive) | Soft-stop a follow: no more intents, history preserved. Re-follow later with create_subscription. |
get_executions | read-only | Your copy-intent inbox + history — coin, direction, sized order, skip reason, status, recorded fill. |
record_execution | write | Mark a pending intent acted (optionally with your fill signature) or dismissed. Never signs for you. |
get_earnings | read-only | Your 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.
`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).

|---|---|---|---|
THREE_WS_API_KEY | all tools except get_earnings with agent_id | — | API key (sk_live_…) or OAuth token. Treat like cash. |

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:
error | Meaning | Recovery |
|---|---|---|
missing_credential | The tool needs auth and THREE_WS_API_KEY is unset. Thrown before any request is sent. | Set the key. |
validation_error | Bad arguments caught client-side, e.g. sizing_rule: "fixed" without a positive fixed_sol. | Fix the call. |
no_changes | update_subscription was called with only an id. | Pass at least one field to change. |
not_found | update_subscription was given an id that is not one of your subscriptions. | Check list_subscriptions. |
upstream_error | The 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. |
timeout | No response within THREE_WS_TIMEOUT_MS. | Retry or raise the timeout. |
network_error | The request never reached the API (DNS, offline, TLS). | Check connectivity / THREE_WS_BASE. |
bad_config | THREE_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. |
