## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: describe_metric (destructiveHint, idempotentHint, openWorldHint); compute_portfolio_var (destructiveHint, idempotentHint, openWorldHint); compute_spread_greeks (destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,153 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,153 tokens to load them all
- tool set hash: c837ce1985d8f732f290ca6461ac056e
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.dripmetrics/mcp.svg)](https://protogrid.dev/servers/ai.dripmetrics/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `compute_portfolio_var`: 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.
- `compute_spread_greeks`: 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_metric`: Free. Returns full details for one metric id from list_metrics: parameters, request/response schemas, price, and how to fetch it.
- `get_metric`: 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.
- `get_payment_requirements`: 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.
- `list_metrics`: 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.
