Description
Read-only MCP access to performix.app's public capability guides and book corpus.
What our measurements say
app.performix/performix-site is a remote MCP server published at performix.app. It has been probed 7 times since 9/12/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 482 ms, placing it among the faster endpoints. It offers a narrow, focused set of 11 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
- Tool names are descriptive and align with their functions (e.g., list_guides, get_book).
- Parameters are well-defined with required/optional flags and clear types.
- No tool overlap; each function serves a distinct purpose.
Weaknesses
- Some descriptions are excessively lengthy (e.g., list_evidence_sources) and could be more concise.
- Error handling is only explicitly mentioned in get_guide_part; other tools lack similar clarity.
- Parameter names like 'query' are generic and could be more context-specific (e.g., 'filterQuery').
list_evidence_sources— Description is overly verbose and lacks focus on usage scenarios.get_guide_part— Error handling is mentioned, but other tools lack similar documentation.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
list_guidesList the public, grounded capability guides published on performix.app/guide — each a cross-book model of the evidence for one hard executive capability (e.g. leading an R&D team). Free to read in full; no auth required.
get_guideGet the full free content of one capability guide by slug (from list_guides) — the five-movement Bicycle guide structure (Orient, Map, Master, Reflect, Measure): the pitch/overview, every load-bearing section (summary, why it matters, misconception/reality, how-to, watch-out-fors, grounding), the open tensions in the corpus, and the sources grounding it. This is the same content rendered publicly at performix.app/guide/<slug> — never the entitlement-gated 'depth' layer.
slugstringrequired
list_booksList the performance-science reading corpus behind Performix — book/cluster profiles, each with a stance toward the CAMS diagnostic thesis (ally, orthodoxy, mixed, leave-out) and a one-line argument summary. Optional `query` filters by a case-insensitive substring match against title, authors, tradition and blurb.
querystring
get_bookGet the full grounded profile for one book/cluster record by slug (from list_books): the record's own argument (contrast-not-summary) plus metadata and cross-links. Same content rendered publicly at performix.app/learn/books/<slug>.
slugstringrequired
list_evidence_sourcesList the 196 source records behind Performix's Performance Science Library — each a book, paper or corpus item with at least one derived finding, plus which CAMS dimensions (capability/alignment/motivation/support) its findings touch. Same source list rendered at performix.app/learn/evidence. NOTE: 132 of 196 sources carry an upstream placeholder citation title pending backfill (HO-2431) — check `citationPlaceholder` before treating `title`/`venue` as a real bibliographic record. Optional `query` filters by a case-insensitive substring over authors/title/venue; optional `camsDimension` filters to sources with at least one finding filed on that dimension.
querystringcamsDimensionstring
get_evidence_sourceGet the full source → finding → construct → survey-item evidence chain for one source by id (from list_evidence_sources): its citation, every finding extracted from it, the constructs derived from each finding, and the survey items derived from each construct. Same content rendered at performix.app/learn/evidence/<id>. HONESTY: the citation is exposed as-is, including the 132 sources still carrying a placeholder title (HO-2431) — `citationPlaceholder` says which.
idstringrequired
list_outcome_modelsList the constructed outcome-model register behind Performix diagnostics — 28 per-outcome factor models generated from principia's meta-analytic library, each with its driver count, grade-A driver count, CAMS filing counts, and persona reach. Same register rendered at performix.app/learn/models. Also returns `namedUnmodellable` — outcomes named in the catalog with no constructed model yet. MEASUREMENT-INTEGRITY (PFX-589): this list carries no effect sizes at all; call get_outcome_model for a driver table, which withholds `r` below evidence tier T3 exactly as the public page does.
get_outcome_modelGet one outcome's full driver table by id (from list_outcome_models): every driver's name, definition, CAMS dimension, lens role, evidence grade, study count (k), and evidence-reliability tier — plus drivers cited in the corpus with no meta-analytic effect size, and the personas that own this outcome. Same content rendered at performix.app/learn/models/<id>. MEASUREMENT-INTEGRITY (PFX-589, a portfolio standing rule): a driver's `r` is null unless its tier is T3 — this tool withholds exactly what the public page withholds and nothing less; VOI figures and overlap-corrected variance contributions are never exposed by this tool at any tier.
idstringrequired
list_guide_partsList all 12 parts (8 numbered parts + 4 appendices) of the Team Performance Science Guide, Performix's cited public reference on why team performance varies and the CAMS diagnostic frame — same table of contents rendered at performix.app/learn. Each row carries `status` (live | draft | stub) so a caller can see which parts are actually publishable before calling get_guide_part.
get_guide_partGet the full body of one Team Performance Science Guide part by slug (from list_guide_parts). Same content rendered at performix.app/learn/<slug>. A part whose `status` is `stub` has no publishable body yet and returns an error rather than a placeholder — check `list_guide_parts`' `status` field first if you want to skip those.
slugstringrequired
get_membership_offerGet performix.app's Bicycle Cooperative membership offer for the Performance Leadership chapter — five options (enterprise member, practitioner member, worker, practitioner rent, enterprise rent) with chapter-substituted copy, resolved action labels, and the join URL. Membership options collect interest only until counsel clears; rent options show proposed pricing until confirmed. No payment is taken through this tool.
