Search vendor advisories

search_vendor_advisories
Read-onlyIdempotent

Search vendor-published advisories newest first by keyword, vendor, severity, or CVE presence; withdrawn advisories are excluded.

Instructions

Search or list vendor-published advisories, newest first. A query of 3 or more characters is matched case-insensitively as a substring of each advisory's title, description, vendor name, IDs and affected_products (search_match substring). A query of 1 or 2 characters matches whole words only (search_match word). Filter by vendor (slug), severity band and whether the advisory names any CVE ID. Advisories their vendor withdrew are left out. Returns advisories, each with vendor, vendor_advisory_id, title, severity, cvss_v3_score, cve_ids, summary and affected_products where present, and total, total_capped, limit, offset, search_applied and search_match. A search counts at most 1,000 matches: past that, total is 1000 and total_capped is true, which means 1,000 or more (the note writes 1,000+), never exactly 1,000. Each advisory also carries rejected_cve_ids: the CVE IDs it names whose CVE record was rejected (withdrawn) by its numbering authority, which are not active vulnerabilities. The query is sent in a request header, never in the URL. coverage repeats those beside returned, and gives vendor_windows, each vendor's window in what EchelonGraph holds: vendor, advisories, earliest_vendor_published_at, latest_vendor_published_at, held_since (where that window begins) and history_backfill (in_progress or not_started: older advisories not all held yet). An advisory published before its vendor's held_since may not be held, so no advisory from a vendor is not a finding that it published none. 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. Cut, each row keeps vendor, vendor_advisory_id, title, severity and cve_ids at least, its strings and lists shortened, or rows are left out and the note gives the offset to call next.

Input Schema

TableJSON 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.
limitNopage size (default 20, max 50)
queryNofree text, at most 100 bytes: a product, an advisory ID, a CVE ID or a keyword, e.g. 'exchange server'; 1 or 2 characters match whole words only
offsetNorows to skip (default 0)
vendorNoa vendor slug, e.g. microsoft, redhat, github
has_cveNotrue: only advisories naming a CVE; false: only those naming none
severityNoone severity band

TDQS

A3.8/5.0
Behavior4/5

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

Adds significant context beyond annotations: withdrawn advisories are excluded, rejected_cve_ids semantics, 1,000-match cap with total_capped, coverage window and held_since meaning, 30k cut behavior. Annotations already give readOnly/openWorld/idempotent, so the description earns credit for the extra domain-specific behavior. It is weaker on permissions/rate limits, but this is a read tool.

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?

Front-loaded with search behavior, but very long and dense, stacking many edge cases (total_capped, rejected_cve_ids, coverage, truncation, DATA CUT/TEXT CUT) into one paragraph. Much earns its place but could be structured into bullets or shortened; some repetition around truncation.

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?

Given 7 params with full schema coverage and an output schema, the description covers all material behavior an agent needs: matching rules, filters, exclusions, pagination caps, return fields, coverage semantics, and truncation fallback. Nothing critical is missing for correct invocation.

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 coverage is 100%, so baseline is 3. The description still adds meaning: query length behavior (1-2 chars whole words, 3+ substring), case-insensitive fields matched, vendor slug filtering, severity band, has_cve semantics, and mentions query is sent in a request header not URL. These go beyond the schema text.

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?

States a specific verb and resource ('Search or list vendor-published advisories') and specifies ordering ('newest first'). The sibling get_vendor_advisory and vendor_advisories_for_cve are related but the description does not explicitly contrast with them, though it broadly distinguishes search/listing from retrieval.

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?

Implied usage as a search/list tool, but no explicit when-to-use vs alternatives. It does not say to use get_vendor_advisory for a single advisory or vendor_advisories_for_cve to pivot from a CVE, which would help route the agent among siblings.

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