Description
63 deterministic quant computation tools for AI agents. Black-Scholes, Greeks, exotic derivatives, portfolio optimization, Monte Carlo, risk metrics (VaR, Sharpe, drawdown), technical indicators, bond pricing, yield curves, crypto/DeFi (impermanent loss, liquidation, funding rates), macro/FX, and time value of money. Pure math — same inputs always produce same outputs. 1,000 free calls/day, no API key required.
What our measurements say
quantoracle is a remote MCP server published at mcp.quantoracle.dev. It has been probed 6 times since 9/10/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 375 ms, placing it among the faster endpoints. It exposes a broad tool surface of 80 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Excellent 'Use when...' documentation pattern for all tools
- Clear and logical hierarchical naming convention (e.g., crypto_, fx_, stats_)
- Explicit operational constraints provided (e.g., Monte Carlo limits)
- High domain specificity with no significant tool overlap
Weaknesses
- Use of single-letter mathematical notation for parameters in some tools
- Minor text truncation in long descriptions
options_price— Uses cryptic single-letter parameters (K, S, T, q, r) which may increase reasoning errors compared to descriptive names.simulate_montecarlo— The description text is truncated at the end of the string.
Verdict
Event narrative
Risk: medium
- 2026-09-10T21:16:35.016Z — era changed from 'auth-gated' to 'legacy' · may indicate access control policy shift
- 2026-09-11T07:35:54.413Z — complianceScore changed from null to 100 · now shows full compliance with operational standards
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 138ms → warm 141ms (penalty 0ms)
