Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1292 tokens (~117/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management47
- Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the app.performix/performix-site MCP server?
app.performix/performix-site is a hosted endpoint at https://performix.app/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_book Get one Performix book profile ~74
Get 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>.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Book slug, e.g. aguinis-performance-management. |
| Name | Type | Req | Description |
|---|---|---|---|
| book | object | yes | – |
No examples provided.
get_evidence_source Get one Performance Science Library evidence chain ~137
Get 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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Source id, e.g. source.corpus.aguinis_2019 (from list_evidence_sources). |
| Name | Type | Req | Description |
|---|---|---|---|

No examples provided.
get_guide Get one Performix capability guide ~134
Get 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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Guide slug, e.g. lead-high-performing-rd-team. |
| Name | Type | Req | Description |

get_guide_part Get one Team Performance Science Guide part ~112
Get 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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Guide part slug, e.g. part-2-capability (from list_guide_parts). |

No examples provided.
get_membership_offer Get the Bicycle Cooperative membership offer ~83
Get 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.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| api_version | string | yes | – |
| chapter | string | yes | – |

get_outcome_model Get one Performix outcome model ~177
Get 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.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Outcome id, e.g. quota_attainment (from list_outcome_models). |
| Name | Type | Req | Description |
|---|---|---|---|
| model | object | yes | – |
No examples provided.
list_books List Performix's performance-science book corpus ~96
List 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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | – | Case-insensitive substring filter against title/authors/tradition/blurb. |

list_evidence_sources List Performix's Performance Science Library sources ~191
List 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.
| Name | Type | Req | Description |
|---|---|---|---|
| camsDimension | string | – | Restrict to sources with at least one finding filed on this CAMS dimension. |
| query | string | – | Case-insensitive substring filter against authors/title/venue. |
| Name | Type | Req | Description |
|---|---|---|---|
| count | number | yes | – |
| sources | array | yes | – |
No examples provided.
list_guide_parts List the Team Performance Science Guide's parts ~93
List 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.
Input schema present but exposes no named parameters.

list_outcome_models List Performix's constructed outcome models ~138
List 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.
Input schema present but exposes no named parameters.
