    Why it is in this group

    • The description's first verb is "start": a word for a change.
    Description, as the server wrote it
    Start monitoring a company domain: Revnuvo scans it on your chosen interval (24h on the free plan, 6h on paid plans), records every observation, detects changes, and you retrieve new signals via revnuvo_search_signals or receive webhook/email deliveries configured in your Revnuvo dashboard. Use it to answer 'alert me when something changes at this company'. Counted against your plan's domain limit.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Verify what Revnuvo can substantiate about a company domain: whether it has observation history, how many observations, the latest observed state hash, and (when the Trust service is reachable) an independent infrastructure trust score. Use it for diligence flows that need evidence-backed company verification rather than assumptions.

    Why it is in this group

    • The name "revnuvo_get_company" says "get": a word for reading.
    Description, as the server wrote it
    Retrieve an overview of a company domain from Revnuvo's observation history: current technologies (with confidence), DNS records, first/last observation timestamps, total observation count and the hash of the latest observed state. Use it to answer 'what do we know about this company?'. Returns not_observed (404-equivalent) when Revnuvo has no history yet.

    Description, as the server wrote it
    Retrieve observed changes at a company domain: technology added/removed/changed, DNS/MX and nameserver changes, and website-state changes — each with before/after values, detection timestamp, confidence and evidence. Answers 'what changed at this company and when?'.

    What it can reach

    • untrusted-inputThe description's first sentence says "retrieve" and "http": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Retrieve the company's latest full observed state: HTTP status and server headers, detected technologies with per-technology evidence and confidence, detected scripts, and DNS (NS/MX/A) records. This is a point-in-time measurement, timestamped and hashed. Use it when you need the complete current picture rather than a summary.

    Why it is in this group

    • The name "revnuvo_get_company_technologies" says "get": a word for reading.
    Description, as the server wrote it
    Retrieve the technologies currently detected at a company domain — each with name, category, version when detectable, confidence (0-1), and the evidence string that produced the detection (e.g. a header value or a script URL). Answers 'what technologies does this company use?'. Absence of a technology means not-detected, never proven-absent.

    Why it is in this group

    • The name "revnuvo_get_company_timeline" says "get": a word for reading.
    Description, as the server wrote it
    Retrieve the chronological observation history for a company: each observation's timestamp, source, confidence and state hash, plus every detected change event with before/after values. Use it to answer 'how did this company's stack evolve?'. History depth depends on your plan (free: 7 days).
  • revnuvo_search_companySearch companies previously observed by Revnuvo.No findings

    Why it is in this group

    • The name "revnuvo_search_company" says "search": a word for reading.
    Description, as the server wrote it
    Search companies previously observed by Revnuvo. Returns the domain, when it was first seen, how many observations exist, its most recently detected technology stack, and the last scan time. Use this to check whether Revnuvo already has history for a company before querying deeper. Only observed companies are returned — nothing is invented.
  • revnuvo_search_signalsSearch Revnuvo's signal feed across all observed companies.No findings

    Why it is in this group

    • The name "revnuvo_search_signals" says "search": a word for reading.
    Description, as the server wrote it
    Search Revnuvo's signal feed across all observed companies. Filter by domain, technology (e.g. 'vue', 'hubspot'), event type (technology_added, technology_removed, technology_changed, mx_changed, nameserver_changed, website_changed) and minimum signal score (1-100). Answers 'which companies recently adopted technology X?' — every signal includes before/after state, evidence and confidence. Signals are observed changes, not purchase-intent claims.

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 write2
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.

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 revnuvo-company-intelligence. Review it before you use it.
