CWE and its CVEs

get_cwe
Read-onlyIdempotent

One CWE (weakness class) and the CVEs classified under it. Returns cwe_id, name and description (from the MITRE CWE catalog EchelonGraph embeds, version catalog_version), total (the active CVEs in EchelonGraph's feed that an NVD, GitHub or CVE.org record classifies under it, rejected and reserved records left out), and cves, one page of 50: each with cve_id, severity, cvss_v3_score, echelongraph_score, echelongraph_severity, score_assessed, kev_listed, published and a shortened description. order says how the rows are sorted (CISA-KEV-listed first, then EchelonGraph score); an answer without order does not state its order, and the note says so. page is the page served, page_size its size and max_page the last page the API serves: a later page is answered as max_page, so past max_page pages total counts CVEs no page lists. echelongraph_score is EchelonGraph's score only when score_assessed is true; the note labels each row that is NOT YET SCORED. A total of 0 says that no CVE in EchelonGraph's feed is classified under that CWE, not that none exists. Pass cwe_id like CWE-79 (or 79) and an optional page (1-200). Its structured result carries state (measured), measured_at (null), method, coverage (total, returned, page, page_requested, page_size, max_page), freshness (null) and notes, with data equal to the API's JSON; the result's last text block repeats it without data (the first text block) and without the note's sentences (the text block before it), with which notes ends. 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

NameRequiredDescriptionDefault
fullNotrue: 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.

TDQS

A3.8/5.0
Behavior5/5

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

Beyond the annotations, it discloses ordering behavior, max_page clamping, score_assessed caveats, truncation modes, and text-block duplication semantics. These are substantial behavioral details not captured by the structured annotations.

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

Conciseness2/5

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

The description is a dense run-on paragraph that repeats return-value details already available in the output schema and buries key caveats in nested clauses. It front-loads the purpose but is not appropriately sized or structured.

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 with complex pagination, truncation, and composite result shapes, the description covers the important edge cases an agent needs and the output schema exists. It is complete, even if overlong.

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

Parameters3/5

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

Schema description coverage is 100%, and the schema already documents full, page, and cwe_id in detail. The description largely restates the same parameter behavior, so the baseline 3 is appropriate.

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

Purpose4/5

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

Opens with a clear verb+resource: one CWE and the CVEs classified under it, then enumerates the returned fields. It does not name or distinguish sibling tools such as get_cve or search_cves, so it falls short of a 5.

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

Usage Guidelines3/5

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

Provides mechanics such as passing cwe_id like CWE-79 (or 79), an optional page 1-200, and the meaning of total 0. It never says when to choose this tool over get_cve or search_cves, so usage is only implied by the purpose.

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