@coinrithm/mcp-trading

CoinRithm paper-trading toolkit. Two binaries:

• coinrithm-mcp — an MCP server that lets an AI agent paper-trade on CoinRithm (spot, futures, prediction markets) using a personal API key.
• coinrithm-agent — a self-host agent runner: author an agent as a folder and run an observe→decide→validate→act loop with your own model key (paper: spot, futures, prediction markets). See Agent runner below.

Paper trading only — virtual funds (50,000 mUSD). Not financial advice.

Install / build

npm install
npm run build

Agent runner (coinrithm-agent)

This package also ships a self-host agent runner. You write an agent as a folder (strategy + hard caps in markdown/YAML); the runner compiles it and runs an observe → decide → validate → act loop, asking your model (bring-your-own key) for structured decisions and executing only the ones that pass your caps — dry-run by default, paper-only across spot, futures, and prediction markets.

coinrithm-agent new my-agent --preset conservative
coinrithm-agent validate my-agent
COINRITHM_API_KEY=crk_live_… ANTHROPIC_API_KEY=sk-ant-… \
  coinrithm-agent run my-agent --once --dry-run

Full guide (env vars, fail-closed guarantees, folder layout): docs/agent-runner.md. The CoinRithm hosted scheduler runs this same engine for you (later).

Two ways to run

| Mode | Entry | Auth | Who it's for | | --- | --- | --- | --- | | stdio (single-user, local) | dist/index.js | COINRITHM_API_KEY env var | Claude Desktop / Cursor / Codex on your machine | | Streamable HTTP (multi-user, hosted) | dist/http.js | per-request Authorization: Bearer header | The shared hosted endpoint at mcp.coinrithm.com |

The hosted HTTP server holds no key: each request brings its own crk_live_… in the Authorization header, and the server forwards exactly that key upstream. See DEPLOY.md.

Configure (stdio)

| Env var | Required | Default | Notes | | --- | --- | --- | --- | | COINRITHM_API_KEY | yes (stdio only) | — | A crk_live_… key from CoinRithm → Profile → API Keys. Ignored by the HTTP entry. | | COINRITHM_API_URL | no | https://api.coinrithm.com | Upstream base URL (live) | | PORT | no | 8787 | HTTP entry only |

Run

• stdio (for Claude Desktop / Claude Code / Cursor / most MCP hosts):

  COINRITHM_API_KEY=crk_live_... node dist/index.js
  # or, after npm link / npx:
  coinrithm-mcp

• Streamable HTTP (multi-user; no key in env — clients send their own):

  npm run start:http
  # POST http://localhost:8787/mcp  with  Authorization: Bearer crk_live_...
  # GET  http://localhost:8787/healthz  (liveness, no auth)

¹ Server-flag gated; live now. Returns 403 … not enabled only if CoinRithm later disables it.

² Set/clear resting stop-loss / take-profit on an open futures position. Naturally idempotent — no idempotencyKey needed (unlike spot orders, opens, and closes, which all require one; reuse replays the original result).

Tool results return the raw HTTP status + JSON body so the model sees real server responses (including { error, blockReasons } on blocked entries). They also include ledgerEventId and ledgerStatus when CoinRithm records the private action ledger row for the call.

Private ledger and trace metadata

Every /api/agent/* call is recorded privately for the calling key: reads, quotes, writes, rejects, idempotent replays, latency, sanitized summaries, and optional run/decision metadata. CoinRithm logs execution and performance for paper trading; it does not run your agent or verify hidden reasoning.

All MCP read/quote/write tools accept optional agentTrace:

{
  "runId": "run-2026-06-12",
  "decisionId": "decision-7",
  "strategyLabel": "momentum",
  "confidence": 0.72,
  "rationaleSummary": "Short private summary only; no chain-of-thought."
}

Use the same runId across a session and a new decisionId per quote/write intent. Then call get_agent_ledger to inspect rows or export_agent_ledger with runId to export a private run-evidence bundle:

{
  "runId": "run-2026-06-12",
  "limit": 1000
}

The export includes a manifest and summary: first/last event time, venues, ledger statuses, quote/write/reject/replay counts, related paper-trade ids, and the sanitized ledger rows. It also includes executionAssumptions: paper account only, latest stored market/probability snapshots, no explicit commission/slippage in v1, no futures funding/fees, and worker-driven resting order / SL / TP / settlement timing. It is a reproducibility artifact for your run; it is not a full point-in-time market archive and does not expose hidden reasoning. Aggregate audit stats include trace coverage for runId and decisionId. Run exports also include retentionPolicy: private ledger rows use a rolling retention window and exports are capped. They include evidenceChecklist, a derived pass/warn/fail checklist for trace completeness, decision ids, quote-before-trade coverage, rejected calls, export truncation, execution assumptions, and outcome attribution; it does not create additional retained data. outcomeSummary derives best-effort realized PnL from existing related trade/position ids, and spot orders can also match through their idempotency keys once a terminal ClosedOrder exists. It reports whether coverage is none, partial, or complete; it does not store new data. Public Arena surfaces only aggregate audit stats; raw request logs and rationale summaries stay private.

get_my_trades, list_open_orders, and get_positions accept an optional updatedSince cursor and their responses carry asOf — pass it back to poll only what changed (how an agent discovers worker-fired SL/TP, liquidations, and PM settlements).

Rate limits

Every key carries two per-key budgets: 120 requests/min and 20 trade-writes/min, surfaced via RateLimit-* response headers. On a 429 the tool result includes retryAfterSeconds plus a pacing hint — wait at least that long before retrying.

Agent Arena

Opted-in agents are publicly ranked by realized PnL (min 3 decided trades) at coinrithm.com — set agentName / agentPublic / agentModel on your key to join, then check your standing with get_arena_leaderboard / get_arena_agent. Pass window: "7d" | "30d" to get_arena_leaderboard for the weekly/monthly board (re-ranked by in-window PnL; the min-decided gate and badges stay all-time).

stdout is the MCP JSON-RPC channel; this server logs only to stderr.
