## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__ptpge__ptpge_browse` `mcp__ptpge__ptpge_check_domain` `mcp__ptpge__ptpge_fingerprint` `mcp__ptpge__ptpge_get_version` `mcp__ptpge__ptpge_validate_document` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `ptpge_browse` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "ptpge_browse" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "ptpge_browse" says "browse": a word for reading.
```

- **info** Long descriptions in `ptpge_validate_config` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,422 characters long, over the 2,000 this check looks for.

description ends: "...; the specification sets no limit on the number of spot colours (the press does)."
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `ptpge_fingerprint`

- The description says "cannot be undone".
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Side effect: the spec-profile fingerprint is registered in the public register at ptpge.org/f (no personal data; same configuration → same entry; cannot be undone). Compute the canonical ptpge-cfs/1 serialization and SHA-256 fingerprint of a resolved product configuration (SD-0040) — the vendor-neutral identity used as quote/order/cache key. Returns both profiles in strict containment spec ⊂ request: 'spec' = the manufacturable artifact, commercial cluster excluded; 'request' = spec plus the commercial cluster — the variables under variables/order/ (quantity, lead-time, delivery-method, incoterm; SD-0040) without a vendor. An 'offer' is a request plus variables/order/vendor, one per vendor (SD-0108). Transaction data (print-ready file, delivery date, price) is keyed BY the request fingerprint and never hashed into it. SD-0083: the input is validated first and an identity is issued ONLY for a valid, complete configuration — every required axis of the product bound (or envelope-implied where the envelope offers one value; those are written into the identity) and every surface one of the bound setup's faces. Otherwise the result is error=not_fingerprintable with the validator's needs_disambiguation: put each question to the user verbatim, bind the answer, call again. Never guess a missing axis.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `ptpge_browse`

- The name "ptpge_browse" says "browse": a word for reading.
- The description's first verb is "navigate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The name "ptpge_browse" says "browse": it reads web pages, which anyone can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Navigate the PTPGE hierarchy. Returns a node and its children (id, notation, label, level, elementType, hasChildren). Omit id_or_path to get the three top concepts (printing, ordering, variables). Use this for systematic exploration instead of guessing search keywords.
```

### `ptpge_check_domain`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Does an agent find PTPGE on this domain? Fetches exactly what a checkout agent fetches — https://<domain>/.well-known/ucp (the UCP manifest and its ptpge block), the vendor declaration at /.well-known/ptpge/declaration.json, the identity in the vendors register, and a supplier catalogue if the domain is a maker — and validates each against its published JSON Schema (ptpge.org/v1/schemas/) and the vocabulary. Returns a verdict (ready | partial | none), one line per step with errors and warnings, what the agent sees (name, identity, products, capability counts) and what is missing with where to fix it. Read-only; nothing is stored. Use it to answer 'is <printer> agent-ready?' or 'why does my declaration not validate?'.
```

### `ptpge_expand_fingerprint`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Expand a spec or request fingerprint (ptpge-cfs/1, full 64-hex or 16-hex short form) back into its structured configuration — the read-back path for MIS/ERP: matched profile, product, every binding with resolved labels, the canonical string, and the dataset version. This is a LOOKUP in the public resolver (ptpge.org/f/), not an inversion of the hash: it resolves when the fingerprint has been registered (every fingerprint computed by ptpge_fingerprint is self-registered within seconds). An unregistered fingerprint is still a valid identity — it simply has no stored expansion yet; returns status 'unknown' then.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `ptpge_get_product_envelope`

- The name "ptpge_get_product_envelope" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the complete Configuration Envelope of a product class in one call: supportsSetupModel, every supports* and perSurfaceSupports* predicate with resolved labels, plus typical* descriptors. This is the full menu of what can be configured for the product — use it before composing a configuration, instead of many individual ptpge_get_term calls. Absent predicates mean NOT supported (closed semantics).
```

### `ptpge_get_term`

- The name "ptpge_get_term" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch full context for a single PTPGE term: definition, broader/narrower relations, exactMatch / closeMatch mappings, properties, notation, level, and metadata. Accepts either a full URI (https://ptpge.org/v1/...) or a relative path under /v1/.
```

### `ptpge_get_version`

- The name "ptpge_get_version" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Return the current PTPGE dataset version, total term count, counts per level and per group, license, scheme URL, and server version. Useful for version-pinning, health checks, and diagnostics.
```

### `ptpge_resolve_color_notation`

- The name "ptpge_resolve_color_notation" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve print colour pair notation (4/4, 4/1, 4+4) into per-surface colour bindings for a given product. The number is a COUNT OF SEPARATIONS, not a colour: it is resolved by searching the combinations this product's envelope actually supports whose colorChannelCount sums to that number. Returns one of three outcomes per surface — a deterministic binding, `needs_disambiguation` with the candidate combinations, or `invalid_for_template` when no combination is possible. IMPORTANT: when `needs_disambiguation` is returned you MUST put its `question` to the user and never infer the answer yourself. '1' is black on some products and a named spot colour on others; guessing gives two different products the same identity. Do not fingerprint an unresolved configuration.
```

### `ptpge_search_terms`

- The name "ptpge_search_terms" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free-text search over the PTPGE vocabulary and registers — the open specification of print. Returns a ranked list of matching terms with their URI, notation, preferred label, level (top-concept / group / category / sub-category / element), group, and a relevance score (0.0–1.0).
```

### `ptpge_validate_config`

- The name "ptpge_validate_config" says "validate": a word for reading.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Envelope validation of a product configuration against the specification: checks every binding against the product's supports* envelopes. When a value is not in this template's envelope but another template takes every bound value, the result carries alsoOfferedBy (ranked) and switchHint — switch product and validate again rather than dropping what the buyer asked for (a poster on aluminium composite is a panel print). Maps numeric substrate-weight (gsm) to its weight band via the bands' minWeight/maxWeight properties, and returns data-driven advisories (e.g. creasing recommended above the scoring thresholds). NOTE: this validates the ENVELOPE only — cross-variable legality (e.g. valid panel counts per fold topology) and vendor capability matching are an implementation's concern (a configurator), not the specification's; commercial values (date, price) are not configuration and belong to the transaction layer. Elicitation contract (shared by every ptpge_* tool): whenever a result carries `needs_disambiguation`, each entry has a `field`, a `question` that MUST be put to the user verbatim, and `candidates` — never infer the answer, never fingerprint until it is resolved. SD-0083: the validator also checks completeness — a missing REQUIRED axis of the product (setup/fold, format, page count, binding, colour on the first face, shape where shape is the product) returns needs_disambiguation with the envelope's candidates; a required axis with exactly one allowed value is bound for you as envelope-implied; a surface name that is not a face of the bound setup (faces: flat-sheet front/back, folded-sheet outside/inside, multi-page front-cover…back-cover) is rejected with the allowed faces. `complete: true` means an identity can be issued. SD-0104 spot inks: a spot-color layer in color-mode is not identified until it is named — bind variables/features/spot-ink on the same face with the value <matching-system term>/<code>: Pantone 300 C → printing/standards/color-systems/color-matching-systems/pantone-matching-system/300-c, HKS 43 K → …/color-matching-systems/hks/43-k, RAL 5015 → …/ral/5015 (code lower-case, spaces as hyphens; checked for form only). One spot-ink per spot-color layer; two spots = color-mode values [cmyk, spot-color, spot-color] + two spot-ink values. Fewer inks than layers → needs_disambiguation; the specification sets no limit on the number of spot colours (the press does).
```

### `ptpge_validate_document`

- The name "ptpge_validate_document" says "validate": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Validate ONE document you hand over — a vendor declaration, supplier catalogue, request, quote or UCP manifest (its `schema` field says which) — against the published JSON Schema, the vocabulary (every term URI must exist; deprecated warns) and, for request/1 and quote/1, the identity: the spec and request fingerprints are recomputed from the configuration and must match what the document states; a quote's offer fingerprint must equal request + the quote's vendor (SD-0108). Nothing is fetched from any domain and nothing is stored. This is the PTPGE Ready conformance check for a module that writes these documents (ptpge.org/ready/). Returns valid, errors[], warnings[] and what was checked.
```
