RiskState MCP Server

MCP server for RiskState — deterministic risk governance API for autonomous crypto trading agents.

Your agent asks: "How much can I risk?" RiskState answers with: policy level, max position size, leverage limits, blocked actions.

What it does

Wraps the RiskState /v1/risk-state API as an MCP tool. One tool: get_risk_policy.

Field	Description
`policy_level`	5 levels: BLOCK_SURVIVAL, BLOCK_DEFENSIVE, CAUTIOUS, GREEN_SELECTIVE, GREEN_EXPANSION
`max_size_pct`	Maximum position size as % of portfolio (0-100)
`leverage_max`	Maximum allowed leverage multiplier
`allowed_actions`	What the agent CAN do at this policy level
`blocked_actions`	What the agent CANNOT do
`confidence_score`	Signal agreement x data quality (0-1)

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 to POST /v1/risk-state 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

Variable	Required	Description
`RISKSTATE_API_KEY`	Yes	API key from riskstate.ai (free during beta)
`RISKSTATE_API_URL`	No	Custom API base URL (default: `https://riskstate.netlify.app`)

Claude Desktop

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

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

Claude Code

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

Set the API key in your environment:

export RISKSTATE_API_KEY=your-api-key

Usage

The server exposes one tool: get_risk_policy

Parameters

Parameter	Type	Required	Description
`asset`	`"BTC"` \| `"ETH"`	Yes	Asset to analyze
`wallet_address`	string	No	DeFi wallet for on-chain position data
`protocol`	`"spark"` \| `"aave"`	No	Lending protocol (default: spark)
`include_details`	boolean	No	Include full breakdown (subscores, macro, risk flags)

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:

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

Limitations

v1 scope: BTC and ETH only. More assets planned.
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.
