Occam
Description
Occam is an MCP server that discovers mathematical equations from numerical data. Give it measurements, get back governing equations — ranked by the tradeoff between simplicity and accuracy.
What our measurements say
Occam is a remote MCP server published at occam.fit. 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 427 ms, placing it among the faster endpoints. It offers a narrow, focused set of 4 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
- Clear differentiation between SINDy and PySR for differential vs. algebraic equations
- Rate limits and usage context explicitly documented for feature_request
- Pysr_uncertainty logically follows from pysr_run workflow
Weaknesses
- Truncated descriptions in sindy_run and pysr_run (ends with 'Pri' and 'For differential equation')
- Feature_request tool name is generic and lacks mathematical context
- No explicit error handling documentation beyond rate limits
sindy_run— Description truncated mid-sentence (ends with 'Pri')pysr_run— Description cut off mid-sentence (ends with 'For differential equation')feature_request— Tool name lacks mathematical context for an MCP server
Verdict
Event narrative
Risk: medium
- 2026-09-10T21:16:35.016Z — Era changed from 'auth-gated' to 'legacy' · Indicates a shift in operational framework requiring compliance validation
- 2026-09-11T05:44:28.819Z — ComplianceScore improved from null to 100 · Confirms full regulatory compliance in legacy environment
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 110ms → warm 110ms (penalty 0ms)
