RiskState — Crypto Risk Engine

RiskState MCP Server

MCP server for RiskState — pre-trade risk permissions for BTC/USD and ETH/USD. Spot, perpetual futures (perps), and DeFi borrowing aware.

Your system asks: "How much can I risk right now?" RiskState answers with: policy level, max exposure, leverage limits, blocked actions — computed from 30+ real-time signals.

Two ways to use RiskState over MCP

1. Remote connector — no install, no API key. RiskState runs a hosted MCP server (Streamable HTTP) with a free public tier:

https://api.riskstate.ai/mcp

Add it as a custom connector in Claude or ChatGPT, then just ask what the risk state of BTC is. It exposes three read-only tools — get_risk_state, get_market_structure, get_playbook_status — covering all three engines, and is listed on the official MCP registry as ai.riskstate/mcp.

Responses are the free public summary: the same altitude as the public visualizer. policy_hash, composite subscores, positioning and macro detail need a key.

2. This package — stdio, keyed, full response. Use it when you want the complete audited payload in a local agent, or to pin a version in your own toolchain. It needs a RISKSTATE_API_KEY and returns everything your key is entitled to. That is what the rest of this README covers.

Tools

Four read-only tools, one per question you might ask before a trade:

get_risk_policy returns:

check_trade evaluates a hypothetical book — send the position you are considering plus anything you already hold, since the caps are portfolio-aware. It returns per position whether it is allowed, the size cap in percent and dollars, and reason_codes when it is not. Those are blocking; advisories are informational and do not affect allowed. It places no orders.

get_playbook_status reports a setup as actionable only when its conditions match, no engine vetoed it, and it is not in alert cooldown. Setups that match but already alerted are counted separately, so an agent polling this tool does not act on the same signal twice.

Why there are no write tools

There is no update_policy, no set_limit, no exception management — and there will not be. The premise of RiskState is that the system being governed cannot move its own limits. Every decision is hashed (policy_hash) so it can be audited afterwards against the inputs that produced it; a tool that let the caller rewrite the policy would make that hash meaningless and the audit trail decorative.

So the lifecycle here deliberately lives on one side: the engine computes, the agent reads and complies. check_trade is the closest thing to a dynamic per-trade operation, and it is still read-only — it answers "would this be allowed", never "allow this".

The API aggregates 9+ real-time data sources server-side. See API docs for details.

What this wrapper does (and doesn't)

This is a thin wrapper — it translates MCP tool calls into REST API requests and returns the response. All computation (scoring, policy engine, data ingestion) happens server-side.

This wrapper adds:

• MCP protocol compliance (stdio transport for Claude Desktop/Code)
• Input validation via Zod schemas
• Human-readable policy summary prepended to responses
• Specific error messages (auth, rate limit, timeout) for agent recovery

This wrapper does NOT:

• Cache responses (the API has 60s server-side cache)
• Perform any scoring or computation locally
• Guarantee response schema stability (follows API versioning)

Installation

npm install @riskstate/mcp-server

Configuration

Environment Variables

Claude Desktop

Add to ~/.config/Claude/claude_desktop_config.json:

{  "mcpServers": {    "riskstate": {      "command": "npx",      "args": ["-p", "@riskstate/mcp-server", "riskstate-mcp"],      "env": {        "RISKSTATE_API_KEY": "your-api-key"      }    }  }}

Claude Code

claude mcp add riskstate -- npx -p @riskstate/mcp-server riskstate-mcp

Set the API key in your environment:

export RISKSTATE_API_KEY=your-api-key

Global install (alternative)

npm install -g @riskstate/mcp-serverriskstate-mcp  # starts MCP server on stdio

Usage

The four tools are listed above. get_risk_policy takes:

Parameters

Example Response

{  "exposure_policy": {    "policy_level": "CAUTIOUS",    "max_size_pct": 35,    "leverage_max": 1.5,    "allowed_actions": ["DCA", "WAIT", "SPOT_LONG_CONFIRMED"],    "blocked_actions": ["LEVERAGE_GT_2X", "NEW_POSITIONS_UNCONFIRMED"]  },  "classification": {    "cycle_phase": "MID",    "market_regime": "RANGE",    "macro_regime": "NEUTRAL",    "direction": "SIDEWAYS"  },  "auditability": {    "composite_score": 52,    "confidence_score": 0.72,    "policy_hash": "a3f8c2...",    "ttl_seconds": 60  }}

How Agents Should Use This

Call get_risk_policy before every trade:

1. If policy_level starts with BLOCK → do not open new positions
2. Use max_size_pct to cap position sizing
3. Check blocked_actions before executing
4. Re-query after ttl_seconds (60s cache)

For a sized position, check_trade collapses steps 2-3 into one call: send the position you intend to open along with what you already hold, and read allowed plus reason_codes. Prefer it over re-deriving the cap yourself, since the caps are portfolio-aware and a position that passes in isolation can still breach concentration once aggregated.

get_market_structure and get_playbook_status are context, not permission. Neither one authorises a trade — only the risk policy does. Use them to decide whether a trade is worth proposing, then get_risk_policy / check_trade to learn how much of it you are allowed.

Limitations

• v1 scope: BTC/USD and ETH/USD only (USD-denominated assessment). More assets planned.
• Markets: Spot, perpetual futures, and DeFi borrowing. Same response — interpretation differs by market (see API docs).
• Protocols: Spark and Aave V3 only for DeFi position data.
• Rate limit: 60 requests/minute per API key.
• Latency: ~1-3s per request (9+ upstream data source aggregation).
• Tested with: Claude Desktop, Claude Code. Should work with any MCP-compatible client.
