What Vulners (BYOK) is for

Vulners (BYOK) lets an AI assistant read your own Vulners data through the Vulners API with a key you supply (Vulners API key). Read-only: 7 tools (search_bulletins, get_bulletin, get_cve_affected_packages, get_cve_affected_cpe, search_cpe, list_collections, get_bulletin_history). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to vulners.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Vulners. Vulners and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which public exploits exist for CVE-2023-20198?"
• "Give me the Vulners record for CVE-2024-3400"
• "Which packages are affected by CVE-2021-44228?"
• "Which CPE configurations does CVE-2021-44228 apply to?"
• "What is the CPE for Google Chrome?"
• "Which collections does Vulners hold?"

What it does

• search_bulletins: Search Vulners bulletins (CVEs, vendor advisories, exploits, scanner plugins) with a Lucene query. Returns id, title, type, family, dates, CVSS, EPSS, CVE list and link per hit, plus the total hit count. Query examples: 'Fortinet AND RCE order:published', 'bulletinFamily:exploit AND "CVE-2023-20198"', 'type:cve AND cvss.score:[9 TO 10]'.
• get_bulletin: Get one bulletin by id (a CVE id such as CVE-2024-3400, or an advisory, exploit or plugin id) with title, description, type, family, dates, CVSS score and vector, EPSS and CVE list. The answer is a map keyed by the requested id.
• get_cve_affected_packages: List the packages affected by one CVE across distributions and ecosystems: source advisory id, package name, vulnerable version range, registry (deb, rpm, npm, maven ...) and distro scope.
• get_cve_affected_cpe: List the CPE applicability configurations of one CVE (vendor advisories and NVD), as nested AND/OR nodes with version bounds. The answer can be large for widely affected products.
• search_cpe: Find CPE identifiers for a vendor and product (only CPEs that are linked to CVEs). Returns the best match and further candidates.
• list_collections: List the datasets (collections) in Vulners, such as exploit databases and advisory feeds, with a description, record count and last update time. Sorted by size, largest first.
• get_bulletin_history: Get the edit history of one bulletin: each change with the field, its value at that edition, edition number and time. Long values can make the answer large.

BYOK key

You bring your own Vulners Vulners API key (https://docs.vulners.com/docs/quickstart/authentication/). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to vulners.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://docs.vulners.com/docs/assets/openapi.yaml (the API this connector calls, with a BYOK key)

Live from the Vulners API (vulners.com) with a BYOK key; documentation: https://docs.vulners.com/docs/assets/openapi.yaml. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Vulners. Vulners and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Vulners account.

Vulners (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Vulners (BYOK) is. Vulners (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Vulners data: Search the Vulners vulnerability database for CVEs, advisories and exploits, and read affected packages and CPE data per CVE, with your own API key. You bring your own Vulners Vulners API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Vulners call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to vulners.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Vulners rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Vulners receives. The request we make on your behalf, including the key and the arguments, under Vulners's own terms and privacy policy. Vulners acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Vulners gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Vulners data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Vulners (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Vulners at any time to end all access.

Children. Vulners (BYOK) is a general-audience service operated by the adult using the assistant, under Vulners's own age rules.

Changes. We will post changes here with a new effective date.
