  • compute_portfolio_varPaid via x402 ($0.05 per request).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Paid via x402 ($0.05 per request). Computes empirical and/or normal parametric VaR for a crypto portfolio. Provide either weights + portfolioValueUsd, or quantities. Invalid portfolios fail before payment.

    Annotations the server declares

    • readOnlyHint: true
  • compute_spread_greeksPaid via x402 ($0.05 per request).No findings

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Paid via x402 ($0.05 per request). Nets Black-76 greeks across up to 6 Deribit BTC option legs and returns a spot×vol scenario P&L grid. Invalid legs or unknown instruments fail before payment.

  • describe_metricFree.No findings

    Why it is in this group

    • The name "describe_metric" says "describe": a word for reading.
    Description, as the server wrote it
    Free. Returns full details for one metric id from list_metrics: parameters, request/response schemas, price, and how to fetch it.

    Annotations the server declares

    • readOnlyHint: true
  • get_metricPaid via x402 (up to $0.25 per request; exact price per metric in list_metrics).No findings

    Why it is in this group

    • The name "get_metric" says "get": a word for reading.
    Description, as the server wrote it
    Paid via x402 (up to $0.25 per request; exact price per metric in list_metrics). Fetches any GET metric by id with query parameters. Without payment this returns the x402 challenge in _meta["x402/error"]; x402-capable clients (e.g. withX402Client) sign it and retry with _meta["x402/payment"] automatically. Invalid requests fail before payment.

    Annotations the server declares

    • readOnlyHint: true
  • get_payment_requirementsFree.No findings

    Why it is in this group

    • The name "get_payment_requirements" says "get": a word for reading.
    Description, as the server wrote it
    Free. Dry-runs a metric request without payment and returns the exact x402 challenge the API issues (accepted networks, asset, amount, payTo). Invalid parameters fail here before any payment.

    Annotations the server declares

    • readOnlyHint: true
  • list_metricsFree.No findings

    Why it is in this group

    • The name "list_metrics" says "list": a word for reading.
    Description, as the server wrote it
    Free. Lists every DripMetrics metric endpoint with its id, family, HTTP method, USD price, and summary. Use describe_metric for parameter details and get_metric (or the compute_* tools for POST endpoints) to fetch values. Paid fetches use x402 (USDC on Base); discovery is free.

    Annotations the server declares

    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__dripmetrics__list_metrics",
      "mcp__dripmetrics__describe_metric",
      "mcp__dripmetrics__get_payment_requirements",
      "mcp__dripmetrics__get_metric"
    ],

      "mcp__dripmetrics__compute_spread_greeks"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as dripmetrics. Review it before you use it.
