Anlyon alternative
Run the operations that matter 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.

find_by_manufacturerList models of one manufacturer, best-documented first, at most 8 per call and no paging (total_matches shows the size).No findings
Why it is in this group
- The name "find_by_manufacturer" says "find": a word for reading.
Description, as the server wrote it List models of one manufacturer, best-documented first, at most 8 per call and no paging (total_matches shows the size). Narrow with category or ship_area, or use search_equipment_models with a designation to reach a specific model.

Why it is in this group
- The name "get_equipment_model" says "get": a word for reading.
What it can reach
- untrusted-inputThe description's first sentence says "get" and "url": it reads web pages, which anyone can write.
Description, as the server wrote it Get one library model (model_ref from a search, or manufacturer + exact designation): category, ship area, page URL, manufacturer datasheet link if any, and the stored technical characteristics. Each value has source_document (label of the catalogue/datasheet it was extracted from; may cover a model series) and source_page. Values were extracted automatically and are not individually reviewed. If there are no stored values the response says so explicitly; never guess specifications in that case. OceanSphere does not hold stock.

list_categoriesList the equipment categories with model counts, optionally for one ship_area.No findings
Why it is in this group
- The name "list_categories" says "list": a word for reading.
Description, as the server wrote it List the equipment categories with model counts, optionally for one ship_area. Use the names as category filter.

list_ship_areasList the ship areas of the library (engine room, deck, electrical, navigation, safety, cargo, HVAC) with model counts.No findings
Why it is in this group
- The name "list_ship_areas" says "list": a word for reading.
Description, as the server wrote it List the ship areas of the library (engine room, deck, electrical, navigation, safety, cargo, HVAC) with model counts.

Why it is in this group
- The name "search_equipment_models" says "search": a word for reading.
Description, as the server wrote it Search the OceanSphere equipment library (marine engines, auxiliaries, pumps, deck machinery, navigation and electrical equipment) by model designation, equipment type or keywords; optionally filter by manufacturer, ship_area or category. Returns at most 8 models (no paging) with manufacturer, designation, category, ship area, the number of source-referenced characteristics, a model_ref and the library page URL. Models without stored values are flagged 'no stored values'. Results with stored values come first. The library identifies equipment; it is not a parts shop - OceanSphere does not list stock. Use model_ref with get_equipment_model.

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 private-data or outbound.
- Reads private data0
- 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.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

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

"permissions": {
"allow": [
"mcp__equipment-library__search_equipment_models",

"mcp__equipment-library__list_categories"
],
"ask": [],
"deny": []
}
}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 equipment-library. Review it before you use it.

Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
