Internet exposure for one CVE

cve_exposure

Read-onlyIdempotent

Count internet-facing services running versions mapped to a given CVE, with country/product breakdown, ransomware flag, and exposure state. Free, keyless, aggregate, host-redacted.

Instructions

Internet-exposure footprint for one CVE from EchelonGraph's KEV-exposure radar: how many internet-facing services (distinct ip:port, returned as exposed_hosts; a machine answering on two ports counts twice) the radar has on record running a version its CVE matcher maps to this CVE, with a country/product breakdown and a ransomware flag. Aggregate and host-redacted; free and keyless. Method: exposure counts are derived from Shodan data. Shodan data is owned by Shodan, which holds its copyright (© Shodan). Every 12 h, when Shodan query credits allow, the radar runs one Shodan query per tracked product, reads up to 100 ip:port services per query, and keeps a service when its banner version matches a CISA-KEV or high-EPSS CVE; a service whose row has not been written or refreshed for 21 days is dropped. The radar only looks for its tracked set of CVEs: for a CVE outside that set the note says NOT ASSESSED (exposure_state not_assessed), and its 0 is not a measurement. last_seen is when EchelonGraph last wrote or refreshed a service's row, not when the service was observed: a port still listed by Shodan InternetDB refreshes it without re-reading the banner, so a patched service can stay counted while its port stays open. A count is therefore a banner-version inference over a sample, not an exploit test and not an internet-wide census. Its structured result's state is not_assessed with measured_at null, since the answer dates no observation; the count is still relayed, labelled, as what the radar holds on record. exposure_state says what the count is: exposed, measured_zero, not_assessed or tracking_unknown; coverage.in_scope is the API's tracked verdict; freshness is null; data is the API's JSON. Past 30,000 characters of JSON, the first text block holds data cut to fit, and the note says what the cut leaves out and where to read it (TEXT CUT); so is structured data (DATA CUT), unless full: true.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`full`	No	true: data in the structured result is the answer whole, however long. Without it, a structured result past 30,000 characters of JSON has its data cut (DATA CUT): in an order the note states, the entries of its longest lists keep only some of their fields, and then the lists only some of their entries; data_truncated is true, and truncated gives each list cut with its total, the number returned and whether its entries are thinned. Whole data is for a program; a client that sizes structured results, as Claude Code does against MAX_MCP_OUTPUT_TOKENS, can refuse an answer past its cap.
`cve_id`	Yes	a CVE ID, e.g. CVE-2023-44487

A4.5/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations cover the safety profile (readOnly, idempotent, non-destructive), but the description goes far beyond them: Shodan-derived sampling methodology, 12h refresh / 21-day drop cadence, 100-service-per-query cap, the meaning of last_seen (write time, not observation time), and the caveat that counts are banner-version inference, not exploit tests or a census. This is exactly the extra behavioral context an agent needs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded in the first clause and most sentences carry genuine information, but the body is a very dense ~2k-character wall mixing methodology, caveats, and truncation semantics that would be better split or trimmed for an agent context budget. It is informative but overloaded rather than economically sized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool that has an output schema, the description still resolves every ambiguity an agent would hit: state values, coverage, freshness null, the not_assessed paradox, and truncation. Nothing needed to interpret or call the tool correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3, but the description adds operational meaning beyond the schema: it explains what the TEXT CUT / DATA CUT labels mean in the response and how full:true interacts with them, plus the MAX_MCP_OUTPUT_TOKENS sizing concern. Marginal but real added value over the schema's own field docs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource+scope: 'internet-exposure footprint for one CVE' returning a count of internet-facing services (distinct ip:port). It also implicitly differentiates itself from the aggregate sibling exposure_radar by scoping to a single CVE and flagging NOT ASSESSED for CVEs outside the tracked set.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear context for when the answer is meaningful – only for the radar's tracked CVE set, otherwise exposure_state is not_assessed and the 0 is explicitly 'not a measurement'. However, it never names a sibling alternative (e.g. exposure_radar) or states an explicit when-not-to-use condition, so it falls short of full routing guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
