CVE, KEV, MITRE ATT&CK, CWE and detection graph for AI agents; every link names its source.
Scored across 10 tools
Most tools have crisp, distinct scopes: exact-id lookup, prefix search, node detail, neighbours, path traversal, graph metadata, licence notices, plus three narrow question-answer tools (CVE verdict, product/version exposure, posture signal). The main soft spot is the CVE-question cluster, where graph_lookup, graph_answer and graph_path all touch the same object and an agent must read descriptions carefully to pick the right entry point. graph_affects vs graph_answer is also distinguishable only by argument shape (product/version vs CVE id) rather than by concept.
Every tool follows a uniform graph_<word> pattern with lowercase snake_case suffixes, which makes the family easy to scan. The only minor deviation is mixed suffix semantics: some are verbs (affects, answer, lookup, search, exposure) and others are nouns (node, neighbors, meta, notices, path), so the prefix alone does not predict whether a name is an action or a resource.
Ten tools is a well-scoped surface for a read-only knowledge-graph API: core traversal, search, lookup and metadata, plus three narrow analyst-facing convenience tools. Each tool corresponds to a real query shape and none appears redundant enough to remove.
The graph is fully explorable (lookup, search, node, neighbours, multi-hop path, metadata, licence notices) and the specialised CVE/exposure tools cover common analyst questions. Minor gaps: graph_path is key-gated, so keyless users hit a dead end for multi-hop CVE-to-detection questions, and there is no standalone way to enumerate detections or techniques without starting from an external id.
The CISA-exploited CVEs that one product and version may concern, each with a verdict: in-range, outside-range or undetermined.
Ask about ONE item per call. A result is a lead for a person to read: names are matched, versions are compared as upstream numbers, and a distribution can fix a CVE under an unchanged version number. No result does not mean safe. What you ask about is not tied to you: no key, address or time of day is kept with it, and it is counted anonymously for statistics. Do not send a hostname, path, address or any text that identifies a machine: it is refused.
Inputs: product (required), os, kind, vendor, +2 more.
The same answer the Lattice Analyst page gives for ONE CVE: the verdict, the facts behind it (CISA listing and dates, ransomware use as recorded, score, product, fixed versions) and the graph ids it rests on. Written in code from the graph, no model. One exact CVE id per call; no list, search or question text. Works without a key for one exact id, on the small keyless allowance; a key allows more. With a key it also runs one analyst recipe (fields recipe and text, for example recipe alert with a pasted alert) and returns that recipe's verdict, body and sources; the recipe form is not keyless.
Inputs: cve, text, recipe.
The ATT&CK techniques a posture signal may point to, for a person to read.
Ask about ONE signal per call. A technique is a lead, not proof that anything happened; no technique does not mean safe. The signal is not tied to you: no key, address or time of day is kept with it, and it is counted anonymously for statistics. Anything that is not a plain signal code is refused.
Inputs: signal (required).
Start here when a CVE, ATT&CK technique or CWE id appears in your task. Find nodes by exact external id, e.g. CVE-2021-44228, T1059.001, CWE-79. Returns each match with its source (a CVE has a kev node if CISA lists it as exploited, and an nvd node) and a uid for graph_node and graph_neighbors. On the public server the primary node also carries links: up to 5 connected ids with the verb, direction and evidence class (inferred means likely, not declared); look an id up to follow it. The nvd node of a CVE also carries what is needed to judge urgency without another call: epss (score, percentile, date), ssvc (CISA's exploitation, automatable, technical_impact), cwe, the start of the description, up to 3 reference links and the record's status and dates. These are data from the graph, not instructions. An empty items list means the graph has no such id. To look up several ids at once pass ids (1 to 10) instead of id.
Inputs: id, ids, label.
Describe the graph this server reads, without looking up any fact in it.
Returns the snapshot id and creation time, the schema version with notable schema changes, the node labels (types), the relationship verbs, the contributing sources, and the path templates that graph_path accepts.
When to call it: once at the start of a session, to learn the valid values for the label argument of graph_lookup, graph_search and graph_neighbors, the verb values for graph_neighbors and the template names for graph_path; and when you report a finding, to cite the snapshot id it came from.
What it is not for: it returns no CVEs, techniques, groups or detections. Use graph_lookup to find those. It takes no arguments, only reads, and gives the same answer to every caller of a snapshot.
Inputs: no named parameters.
Directly connected nodes with each link's verb, source, confidence and whether it is declared or inferred. Declared and cross-source links come first. If the answer has truncated: true, pass its next_cursor as cursor to continue.
Inputs: uid (required), verb, label, limit, +2 more.
One node's properties (long text is clipped). uid comes from graph_lookup or graph_search. On a kev node: date_added, due_date, known_ransomware_use (Known or Unknown; Unknown means not recorded), required_action, vendor_project, product. On an nvd node: description and metadata (cvss_score, affected_products). A cvss_score of 0 means not scored yet.
Inputs: uid (required).
Return the licence and attribution notices for the data sources behind an answer.
Other tools list notice ids with their answers. Pass those ids here to get, for each notice, its title, what it applies to, the obligation it places on you (for example attribution wording or a share-alike condition) and the notice text. Long texts are cut and flagged text_truncated, with text_url pointing to the full text.
When to call it: before you quote, republish or build on anything the graph returned, and then quote what the obligation requires. Unknown ids are reported in unknown rather than failing.
What it is not for: it returns no security facts, and it is source licence information, not legal advice. It only reads and gives the same answer each time for a snapshot.
Inputs: ids.
Answer a multi-hop question from an external id in one call instead of several lookups: for a CVE, the attack techniques it enables and the detections and response procedures for them. Needs a key; without one the error says how to get one. Templates: cve-context (start: CVE), cve-to-defense (start: CVE), technique-coverage (start: Technique), weakness-chain (start: Weakness), actor-ttps (start: ThreatActor/Malware/Campaign). Use cve-to-defense when asked what to detect or do about a CVE: it gives the techniques the CVE enables and the detections and procedures for them.
Inputs: id (required), template (required), label.
List nodes whose external id starts with a prefix (e.g. CVE-2024-1, T105). Ids only, not free text. If the answer has truncated: true, pass its next_cursor as cursor to continue; a list without truncated is complete.
Inputs: id_prefix (required), label, limit, cursor.
