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 Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 673 tokens (~336/item across 2 items; 2 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 Management3
- Stability observed for 1 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 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

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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 →
check_pdf_accessibility Check a PDF's accessibility against PDF/UA ~350
Check whether a PDF is accessible by PDF/UA, the ISO standard for accessible PDF. veraPDF checks the machine-checkable rules of PDF/UA: tags, structure, alt text present, fonts, metadata. Whether alt text or reading order make sense still needs a person. Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the file as a download link in `file`. `profile` is "ua1" or "ua2". Returns `compliant` (true or false), `profile_name`, `statement`, `passed_rules`, `failed_rules` and `top_failed_rules`: up to 10 failed rules with their `id` (clause and test number), `specification`, `description` and `failed_checks`. A file that is not a PDF fails with `not_a_pdf`; an unavailable veraPDF with `engine_unavailable`. For the full report, use the REST API (`POST /v1/verapdf/api/validate/ua1`). Credits: 10 per call.
| Name | Type | Req | Description |
|---|---|---|---|
| file | object | – | The file as a download link, instead of `pdf_base64`. In ChatGPT, pass the user's uploaded file here. Other clients can set `download_url` to a public https URL. |
| pdf_base64 | – | – | The PDF, base64-encoded. At most 4 MB decoded. |
| profile | string | – | "ua1" (the default) checks against PDF/UA-1 (ISO 14289-1), "ua2" against PDF/UA-2 (ISO 14289-2). |
Structured output declared, but exposes no named fields.
No examples provided.
validate_pdfa Validate a PDF against PDF/A ~323
Check whether a PDF conforms to PDF/A, the ISO archiving standard, with veraPDF. Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the file as a download link in `file`. `profile` picks the PDF/A part and level. Returns `compliant` (true or false), `profile_name` (the profile veraPDF used), `statement`, `passed_rules`, `failed_rules` and `top_failed_rules`: up to 10 failed rules with their `id` (clause and test number), `specification`, `description` and `failed_checks`. A file that is not a PDF fails with `not_a_pdf`; an unavailable veraPDF with `engine_unavailable`. For the full report in JSON, XML or HTML, use the REST API (`POST /v1/verapdf/api/validate/{profile}`). Credits: 2 per call.
| Name | Type | Req | Description |
|---|---|---|---|
| file | object | – | The file as a download link, instead of `pdf_base64`. In ChatGPT, pass the user's uploaded file here. Other clients can set `download_url` to a public https URL. |
| pdf_base64 | – | – | The PDF, base64-encoded. At most 4 MB decoded. |
| profile | string | – | The PDF/A part and level, such as "2b" or "3a". "auto" (the default) checks against the part the file declares, and against PDF/A-1b when it declares none. |
Structured output declared, but exposes no named fields.
