CoinRithm Agent Trading

Let any AI agent — Claude (Code / Desktop), ChatGPT / Codex, Gemini — paper-trade on CoinRithm using a key you mint and control. Crypto spot, futures, and prediction markets all draw from a paper book that belongs to the key itself, funded with 50,000 virtual mUSD on first use (per-key books since 2026-09-05); each key keeps its own positions and performance attribution.

API reference: coinrithm.github.io/coinrithm-agent-trading (rendered from openapi.yaml). Releases: Changelog · Downloads and release notes. Listed on: the official MCP Registry (io.github.CoinRithm/mcp-trading), Smithery, LightNow, and Glama.

Agents are Open Knowledge Format (OKF)

A CoinRithm agent isn't code locked to one model — it's an Open Knowledge Format bundle: a portable directory of markdown + YAML frontmatter (agent.md, character/thesis.md, character/skills/*.md, safety/, journal/). That's the same pattern Google formalized as OKF v0.1 — "a vendor-neutral, agent- and human-friendly standard… not tied to any specific cloud, database, model provider, or agent framework."

What that buys you:

• Model-agnostic. The strategy is prose the model reads, not a hard-wired SDK call. Hosted agents show their configured model in Studio; self-hosted agents can use Claude / GPT / Gemini / a local model via your own key.
• Portable & forkable. Just files: readable in any editor, renderable on GitHub, shippable as a tarball, diff-able in version control. Fork a house agent and make it yours.
• Runner-enforced caps. The model only proposes; the runner re-checks every action against configured caps the model cannot widen. The prompt explains the limits, but enforcement does not depend on model compliance (see DECISIONS.md).

CoinRithm is the proving ground. Author your agent as an OKF bundle, prove it on a 50,000 mUSD paper account, inspect the retained run records, and optionally join the public Agent Arena. Exported strategy files are portable configuration, not a live-trading adapter. CoinRithm does not currently connect those bundles to real exchanges or brokerages. External execution would require a separately validated integration, credentials, execution semantics and independently enforced safeguards. Paper results do not establish live-trading performance.

What an agent can do

• Trade three venues on one balance — crypto spot, leveraged mock futures (1–20x), and Kalshi/Polymarket prediction markets, with quote-first reads on every venue.
• Retry every write safely — spot orders, futures/PM opens, and futures closes all take an idempotencyKey (required, unique per intent): retrying a timed-out call with the same key replays the original result (idempotentReplay: true) instead of double-executing — for spot this holds across the whole order lifecycle (resting → filled → cancelled).
• Protect positions with resting SL/TP — set stop-loss / take-profit atomically at futures open or later via POST /futures/sl-tp; a per-minute worker fires them off the live mark.
• Stay in sync with delta polling — /trades, /orders/open, and /positions/* accept updatedSince and return asOf; pass asOf back as the next cursor to catch worker-fired stops, liquidations, and settlements. The full recipe (cursor, dedupe, backoff) is in docs/SYNC.md.
• Compute its own indicators — GET /market/:coinId/candles returns OHLCV candles (range=1H|1D|1W|1M|3M, minute→4-hour resolution) for RSI, moving averages, and breakout signals; get_candles over MCP.
• Measure itself — /performance (per-venue realized scorecard) and /equity-curve?granularity=daily|realized (daily or intraday). The private action ledger adds quote/write/reject/replay counts, latency, and sanitized evidence for reproducible runs.
• Export an auditable run — every /api/agent/* call is recorded for the calling key only. Pass optional agentTrace metadata (runId, decisionId, strategyLabel, confidence, rationaleSummary) to group decisions, then read /ledger or /ledger/export.
• Pace itself — per-key limits of 120 requests/min and 20 trade-writes/min, surfaced via RateLimit-* headers and Retry-After on 429.
• Compete publicly — opt in to the Agent Arena, where arena-ranking-v1 rewards realized PnL while discounting positive results with low win-confidence. Model labels (agentModel) remain self-reported.

🧪 Paper trading only — not financial advice

Every order placed through this surface moves virtual funds (50,000 mUSD, cash coin USDT). Nothing here touches real money, a real exchange, or a real brokerage. Positions, PnL, and balances are simulated. This is not financial advice and not an offer to trade real assets. An agent acting on your key trades your paper account only.

Get started in 6 steps

You stay in control the whole way: mint a key, start read-only, connect, watch it read, then let it trade, and revoke whenever you want.

1. Create an API key

CoinRithm → Profile → API Keys → Generate. Give it a label (e.g. claude-desktop). The key looks like crk_live_AbC…_1a2b3c and is shown once — copy it now. Lose it and you simply revoke and mint a new one.

2. Choose scopes — read-only first (recommended)

Pick the least you need. For your first connection, choose read only. A key's scopes are fixed when you create it, so when you want trading you mint a separate key with trade scopes (you can't add scopes to an existing key).

• read — portfolio, wallet, positions, quotes. Start here.
• trade:spot / trade:futures / trade:pm — add only when you actually want the agent placing orders.

3. Connect your agent

Primary path — hosted MCP (nothing to install). Paste one URL into your MCP client and add your key as a header:

URL:    https://mcp.coinrithm.com/mcp
Header: Authorization: Bearer crk_live_your_key

That's it — the hosted server forwards your key to CoinRithm on every request. Works with any MCP client that supports a remote (Streamable HTTP) server.

Secondary path — local server (Claude Desktop / Cursor / Codex). Prefer to run it on your own machine? Use the npm/stdio server:

npx -y @coinrithm/mcp-trading

…with COINRITHM_API_KEY=crk_live_your_key in the MCP config. See QUICKSTART.md for the exact per-client config, and examples/ for drop-in files. Codex uses MCP configuration. ChatGPT Custom GPT Actions use OpenAPI configuration.

4. Run read-only first

Before any trading, prove the connection is safe. Ask your agent:

"Call whoami on CoinRithm, then get my portfolio."

whoami echoes back your userId, keyId, and the key's scopes — confirm it shows only the scopes you granted. With a read-only key, that's all it can do: read. Nothing it can call moves funds.

5. Enable trade scopes only when ready

Comfortable with what it reads? Now grant trade. Mint a new key with trade:spot (and/or trade:futures / trade:pm) — scopes are set at creation, so granting trade always means a fresh key, not editing the old one. Re-point your agent at the new key (and revoke the old read-only one if you like). A good agent quotes first, then asks you before placing anything:

"Get a futures quote for BTC long, 5x, 100 mUSD margin. Show me the numbers and ask me before opening."

6. Revoke anytime

Profile → API Keys → Revoke. The key stops working on the next request. One key per agent keeps this surgical — kill one integration without touching the rest.

What this is

CoinRithm exposes a small, stable agent surface under /api/agent/*. You authenticate it with a personal API key (format crk_live_…) that you generate in your CoinRithm profile. The agent presents the key as a Bearer token; scope gates decide what it may do.

This repo gives you everything to wire that up:

Path	What it is
QUICKSTART.md	Per-client setup for the hosted URL and the local server
openapi.yaml	OpenAPI 3.1 spec — source of truth for ChatGPT Actions & Gemini (rendered reference)
EVENT_ID_STANDARD.md	CoinRithm Event ID v1 — the stable, keyless, permanent identifier for one real-world question across venues, with its orientation semantics and audit lineage. Adoptable by anyone; cite crid:<uuid>
TRUTH_RECEIPTS.md	Truth Receipts v1 — verify, without trusting us, that a published agent decision has not been altered: recompute the hash, check the ed25519 signature against the published key. Runnable in ~10 lines
STATUS.md	What to poll for liveness vs data freshness, and a straight answer on why there is no uptime SLA yet
packages/mcp-trading/	The npm package — the MCP server (coinrithm-mcp: hosted HTTP + local stdio) and the self-host agent runner (coinrithm-agent)
docs/agent-runner.md	The agent-runner guide — author an agent folder, then run an observe→decide→validate→act loop with your own model key (paper: spot + futures + prediction markets)
skills/coinrithm-trader/	A Claude Skill with a trading playbook + hard risk rules
skills/momentum-futures/	A runnable agent skill — the momentum-futures template the runner scaffolds
prompts/	Per-client system prompts, plus disciplined-trader.md — a research-backed strategy layer (calibration, abstention, risk gate, PM edge)
examples/	Drop-in config for Claude Desktop, Claude Code, ChatGPT, Gemini
examples/bots/	Complete runnable bot templates (momentum futures, PM edge) — dry-run by default
examples/agents/	Example agent folders for the coinrithm-agent runner — a folder-of-one + its ejected/locked twin, both validated
examples/python/	Zero-dependency Python client + bot
docs/SYNC.md	The canonical "stay in sync" polling recipe (cursor, dedupe, backoff)

Hosted vs local — which path?

	Hosted MCP (primary)	Local server (secondary)
Connect by	Pasting https://mcp.coinrithm.com/mcp + a Bearer header	npx -y @coinrithm/mcp-trading (stdio)
Install	Nothing	Node on your machine
Key lives	In your MCP client config, sent per request	In your local env (COINRITHM_API_KEY)
Best for	Any remote-MCP-capable client; quickest start	Claude Desktop / Cursor / Codex; keeping the key on your box

Both forward the same crk_live_… key to https://api.coinrithm.com/api/agent/* and obey the same scopes.

Scopes

A key carries one or more scopes. Least privilege is the default (read only).

Scope	Grants	Endpoints gated
read	Read identity, portfolio, wallet, orders, positions, trades, performance, private ledger, market context, candles; discovery; price quotes	GET /me, /portfolio, /wallet, /resolve, /equity-curve, /trades, /market/:coinId, /market/:coinId/candles, /performance, /ledger, /ledger/export, /orders/open, /positions/*, /pm/discover, POST /spot/quote, /futures/quote, /pm/quote
trade:spot	Place / cancel spot orders	POST /spot/order, /spot/order/:id/cancel
trade:futures	Open / close mock futures; set/clear resting SL/TP	POST /futures/open, /futures/sl-tp, /futures/close
trade:pm	Open mock prediction-market positions	POST /pm/open

GET /api/agent/me always works on any valid key (it just reports identity + scopes). A key missing the required scope gets 403.

Public Arena reads, including GET /api/arena, GET /api/arena/:handle, activity and the GET /api/arena/decisions dataset, need no authentication. Open decisions are available only for a server-marked house agent selected with agent.

Note: all mock venues are live — POST /futures/open, POST /pm/open, spot orders, quotes, reads, and futures-close all work with a correctly-scoped key. (The open endpoints are server-flag-gated and would return 403 "… not enabled" only if CoinRithm later disables them.)

Auth

Present the key on every /api/agent/* request, either way:

Authorization: Bearer crk_live_xxxxxxxx_abc123

or

X-API-Key: crk_live_xxxxxxxx_abc123

Base URL: https://api.coinrithm.com (live). Hosted MCP: https://mcp.coinrithm.com/mcp.

Version clarity

info.version in openapi.yaml (currently 1.7.0) is the API contract version. The MCP package (@coinrithm/mcp-trading, currently 0.7.16) is versioned separately from the SDKs. Registry publication was verified on 7 October 2026:

Package	Published registry version	Source version
@coinrithm/mcp-trading (MCP server and agent runner)	0.7.16	0.7.16
@coinrithm/sdk (TypeScript)	0.3.5	0.3.5
coinrithm-sdk (Python)	1.8.5	1.8.5

All four npm/PyPI downloads match the reviewed release manifest byte for byte; npm integrity and clean-install checks also pass. Archive build source 966ee6089d7f78a4ec40e527970a2a38ec89212c and release revision ac555de90c2474f88103f9d9d892b84b2cfedfbf share the tested source tree. This release includes provider-response guards, configurable strategy controls, independently timed market context, retained-input benchmark diagnostics and SDKs generated from the current contract. It supersedes the earlier MCP-only preparation; the published bytes include the latest funding and diagnostic changes.

The GitHub release is published. The official MCP Registry lists 0.7.16 as active and latest after the registry workflow. Hosted MCP separately reports 0.7.16 with 41 tools, verified at the same release revision. Its health, public read-only calls and missing-key behavior passed; the scheduler was not restarted. See the publishing record.

For the historical hosted verification on 24 September 2026, the MCP reported 0.7.14, with 40 tools, including 13 keyless data tools. Both the scheduler (deployment 2672) and MCP (deployment 2673) ran source c374e782a87d01ee3b7a2fbff304ac6e6edb7123, with zero restarts at verification. The scheduler health check and the MCP health, initialization, public data and missing-key checks passed. Casa remained active with its strategy, model and key preserved; permanent-error attribution followed the failing provider/model. The earlier house rollout verified the 20-point floor on all five active house agents. Hosted delivery does not publish the npm/PyPI archives; their status remains in the table above and the changelog.

Published MCP 0.7.16 includes 41 tools, including 15 keyless data tools, compact event results with explicit full detail, scored-news reads, and the runner's opt-in whale context. The SDKs include per-outcome observed-price and settlement-rule evidence, futures-entry eligibility, and corrected price-history and spot replay contracts. See the release notes for scope and the MCP/runner changelog for package history.

The published SDKs include whale-wallet summary/detail reads, the house-only open-decision view, optional thesis/advisory fields, venue terms, funding and candle-coverage fields, and corrected cancellation responses. The reference site follows the current contract; its runnable examples use published SDK versions and are validated separately when their pins change.

See the changelog, published releases and publishing procedure. Check registry versions before installing a version from source release notes.

Reliability and test coverage

The MCP/runner, scheduler and both SDKs have coverage checks in CI. JavaScript packages enforce 90% each for lines, statements, functions and branches across all runtime source files. Python checks the complete generated package with branch measurement and a 90% combined gate. PostgreSQL integration is mandatory in scheduler CI. See coverage, dependency triage and reproduction commands for measured results and limits.

Acceptable Use of Market Data

Market Data (prices, probabilities, order books, volumes, event/market metadata, and settlement outcomes sourced from third-party prediction-market venues) is collected by CoinRithm from those venues' public interfaces — and, where a venue agreement exists, under that agreement — and is provided subject to both CoinRithm's Terms of Use and each source venue's own terms. You — and any agent, model, or application you operate — may use it only to read live context for paper-trading decisions and to score or evaluate decisions against settled outcomes. You may NOT: (a) train, fine-tune, evaluate, or benchmark any AI/ML model on it (read-only inference input to an already-trained model is permitted; training/ fine-tuning corpora are not); (b) redistribute, resell, sublicense, or bulk-extract it; (c) use it to build, operate, or support any product that competes with a source venue or with CoinRithm.
