3 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.

    Description, as the server wrote it
    Screens 1–50 subjects and returns a self-contained HTML report (result.html): timestamp, each list with its version / fetched-at / SHA-256, the inputs, every hit with its explanation, and an explicit no-match statement for clear subjects — suitable for the client's AML file (open in a browser, print to PDF). One charge per report. Example: subjects [{name:'Qusay Saddam Hussein', dob:'1966'}], case_reference 'KYC-2026-0412', prepared_by 'MLRO'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.

    • 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
    Each subject may carry dob, nationality, entity_type, id_number and your reference. Identical rows are screened once (charged once). Returns per-subject decision_hint, hit_count, top_score and the top 5 hits, plus summary counts (clear / review / likely_match). Charged per unique name. Example: subjects [{name:'Ali Kony', reference:'C-17'}, {name:'شركة الأمل للتجارة', entity_type:'entity'}], default_nationality 'AE'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.

    Why it is in this group

    • 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
    Screen a person, company, vessel or aircraft name against OFAC SDN + Consolidated, UN, EU, UK and the UAE Local Terrorist List. Returns up to 20 hits sorted by score with list, listed_name, aliases_matched, score, match_strength (exact / strong / possible / weak), matched_on (which alias, which normalisation, DOB / nationality / type agreement), programs, listed_on, DOBs, nationalities, id_numbers, reference and source_url, plus decision_hint. Example: name 'Mohamed Hussein Al-Tikriti', dob '1966', nationality 'IQ', entity_type 'individual'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.

    Why it is in this group

    • The name "explain_match" says "explain": a word for reading.
    Description, as the server wrote it
    Normalises both names step by step (Unicode, Arabic letter folding, honorifics/particles dropped, merged 'Abdul…' forms split, romanisation variants folded) and returns every score component (token_sort, token_set, Jaro-Winkler, subset, or the cross-script skeleton) and the resulting score / strength. Free. Example: name_a 'Abd al-Rahman Al Shaikh', name_b 'عبدالرحمن الشيخ'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.

    Why it is in this group

    • The name "list_status" says "list": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Per list: entries (individuals / entities / vessels / aircraft), aliases, fetched_at, days_since_fetch (stale flag when older than 7 days), official source URL and page, SHA-256 of the downloaded file, licence/terms, and any failures of the last refresh. Free. Call it before relying on a 'clear' result in a regulated process. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as sanctions-screener. Review it before you use it.
