get_index_access_optionsCall with {} after a free preview to compare paid saved retrieval, unsigned receipts and executable licences.1 finding
Why it is in this group
- The name "get_index_access_options" says "get": a word for reading.
- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  What this check looks for
Description, as the server wrote it
Call with {} after a free preview to compare paid saved retrieval, unsigned receipts and executable licences. Returns live availability, GBP prices excluding VAT, product requirements and hosted/agent payment contracts, including standalone Tool Admission (GBP49) and Audit Coverage (GBP79). Existing subscriptions exclude all four standalone licences. Use purchase_url for hosted checkout; compatible agents need owner spending authority for the exact quote and must follow agent_payments_contract for payment and recovery. Free evidence needs no payment. Never send keys here; this tool cannot charge or retrieve purchases.

find_evidence_questionsSearch existing reviewed evidence questions and fixed-pack topics when you do not know a route ID.No findings
Why it is in this group
- The name "find_evidence_questions" says "find": a word for reading.
Description, as the server wrote it
Search existing reviewed evidence questions and fixed-pack topics when you do not know a route ID. Use this for governance, tool permissions, audit/export and evidence-boundary questions. For a known software advisory ID or an exact ecosystem/package lookup, use find_package_advisories instead. Supply query as keywords (maximum 160 characters), or leave it blank to browse. offset is the zero-based pagination offset (default 0, maximum 10000; increase by 20). Returns up to 20 matches with route_id, matched wording and the scoped question; pass a route_id to preview_evidence_answer for the complete free answer and sources. Matching ignores case, punctuation and common question words; it does not validate arbitrary new claims. No match is not a negative verdict. Free and read-only.

- destructiveHint: false
- idempotentHint: true

find_package_advisoriesLook up a known advisory ID or alias, or an exact ecosystem and package name in the frozen OSV collection.No findings
Why it is in this group
- The name "find_package_advisories" says "find": a word for reading.
Description, as the server wrote it
Look up a known advisory ID or alias, or an exact ecosystem and package name in the frozen OSV collection. Supply advisory_id OR both ecosystem and package; cursor continues the same lookup. Returns at most 20 concise source matches and route IDs for preview_evidence_answer. Source capture dates and withdrawals are explicit. Full previews include separately dated EPSS/KEV matches and explicit fix boundaries; scores are not asset-risk assessments. No results never mean safe. No range solving, current scanning, independent verification or payment. Free and read-only.

preview_evidence_answerPreview a published answer or pack using route_id from find_evidence_questions or find_package_advisories.No findings
Why it is in this group
- The name "preview_evidence_answer" says "preview": a word for reading.
Description, as the server wrote it
Preview a published answer or pack using route_id from find_evidence_questions or find_package_advisories. Free; returns cited evidence, review dates, limitations and snapshot_sha256. Public packs include complete comparisons. Executable-product previews show scope, schemas and examples, not the licensed ZIP; the original integration kit also has a distinct preview_payload_sha256. Optional version checks exact advisory-listed versions only, not ranges or safety. For prices and licences, call get_index_access_options. No paid saving or live testing.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

1 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
