Description
Source-graded registry of organizational measurement: constructs, priors, instruments, citations.
What our measurements say
com.peopleprincipia/principia is a remote MCP server published at peopleprincipia.com. It has been probed 12 times since 9/12/2026. It answered in 12 of them (100.0%), a near-uninterrupted record. Median response time is 575 ms, a delay an agent will notice. Its tool list could not be read; the server is closed to direct calls. 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
- Tool names explicitly indicate their purpose (e.g., 'principia.constructs.list')
- Descriptions often include usage context (e.g., 'keyword search over construct name + definition')
- Consistent use of 'found:false' for soft validation in lookup tools
Weaknesses
- Some parameter types are ambiguous (e.g., 'min_informativeness' as string in canonical_priors.search)
- Potential overlap between 'principia.constructs.measures' and 'principia.instruments.list'
- Limited error handling documentation for non-lookup tools
principia.canonical_priors.search— Parameter 'min_informativeness' uses string type for numerical valueprincipia.effects.search— Phase 2 status note may confuse agents about functionalityprincipia.evidence.trace— Optional parameters not clearly marked in description

tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- Tool list unreadable — the server responds, but its tools/list call does not return a valid result. Schema checks and AI evaluation cannot run.
- inputSchema invalid: —
- Smoke test not run this round
- Cold-start: cold 154ms → warm 151ms (penalty 3ms)
