17 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.

icx_quote_slotRetrieves exact character-for-character verbatim text and cryptographic SHA-256 hashes from document registers by document family and 1-based slot index without AI paraphrasing.Reads private dataNo findings
Why it is in this group
- The description's first verb is "retrieve": a word for reading.
What it can reach
- private-dataThe description's first sentence says "retrieve" and "document": it reads documents.
Description, as the server wrote it Retrieves exact character-for-character verbatim text and cryptographic SHA-256 hashes from document registers by document family and 1-based slot index without AI paraphrasing. Optional start (0-based character offset) and length (character count) return a verbatim slice of the stored slot text. The slice is the exact stored characters, not a summary. Omit both start and length to return the whole slot. If start or length is out of range, the call errors and does not clamp. sha256 and parent_sha256 are the SHA-256 of the entire stored slot. slice_sha256 is the SHA-256 of the characters returned in exact_quote. Use this tool when exact contractual wording, statutory clauses, license keys, or immutable code revisions must be quoted verbatim without AI modification. Do NOT use for semantic question answering (use icx_recall_scoped), and do NOT use for keyword exploration (use icx_search_facts). Read-only operation with zero side effects.

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.
4 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.
- Reads private data4
- 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 out1
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
