For Agents

Pull Cisco security advisories in CVRF or OVAL format by CVE, severity, year, or product, so an agent can triage Cisco vulnerabilities and feed them into a SIEM or ticketing system.

Quickstart

Get started with Cisco PSIRT openVuln API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"find a Cisco security advisory by CVE"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

Jentic publishes the only available OpenAPI document for Cisco PSIRT openVuln API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Cisco PSIRT openVuln API, keeping it validated and agent-ready. The Cisco PSIRT openVuln API delivers Cisco Security Vulnerability information in machine-consumable formats (CVRF and OVAL), so security teams and AI agents can monitor advisories without scraping the Cisco website. It exposes 19 GET endpoints that retrieve advisories by CVE ID, advisory ID, severity, year, product, and IOS/IOS XE platform. Access is OAuth 2.0 client-credentials, with tokens issued by cloudsso.cisco.com after registering an application at apiconsole.cisco.com.

Use Cases

Patterns agents use Cisco PSIRT openVuln API API for, with concrete tasks.

★ Daily Cisco vulnerability ingest into a SIEM

A security operations team polls /security/advisories/cvrf/latest/{number} every morning to pull the latest Cisco advisories, parses the CVRF XML, and forwards critical and high-severity items into the SIEM as detection rules. The OAuth client-credentials flow makes this safe to run unattended on a scheduler.

Call GET /security/advisories/cvrf/latest/10, filter the response to advisories with severity 'Critical' or 'High', and forward each one to the SIEM ingestion endpoint.

CVE-to-Cisco-advisory lookup during incident response

When a public CVE is reported, an analyst or agent calls /security/advisories/cvrf/cve/{cve_id} to find Cisco's advisory for that CVE, including affected products, fixed releases, and workarounds. This shortens the time from CVE disclosure to a remediation plan from hours to seconds.

Call GET /security/advisories/cvrf/cve/CVE-2024-20399 and return the advisory ID, affected products, and fixed releases.

IOS and IOS XE platform-specific vulnerability scan

Network teams use /security/advisories/ios and /security/advisories/iosxe to retrieve advisories that specifically affect IOS or IOS XE, then cross-reference the affected releases against their inventory of running images. This drives prioritised firmware upgrades on routers and switches.

Call GET /security/advisories/iosxe, extract the list of affected IOS XE releases, and produce an upgrade priority list for the network team.

AI agent vulnerability triage via Jentic

An AI agent connected to Jentic searches for 'find Cisco advisory by CVE', loads the schema for /security/advisories/cvrf/cve/{cve_id}, and executes the call as part of a larger triage workflow that also queries NVD and the customer's asset inventory. Jentic resolves the OAuth token transparently — the agent never sees the client_secret.

Through Jentic, search 'find Cisco advisory by CVE', load the schema for the CVE lookup endpoint, and execute it with CVE-2024-20399 to retrieve the matching advisory.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

The Cisco PSIRT client_id and client_secret are stored encrypted in the Jentic vault (MAXsystem). Jentic performs the OAuth token exchange and injects the bearer token at execution time — neither secret enters the agent's context.

Intent-based discovery

Agents search by intent (e.g. 'find Cisco advisory by CVE') and Jentic returns the matching PSIRT operation with its input schema, so the agent calls the right endpoint without parsing the developer portal.

Time to first call

Direct Cisco PSIRT integration: 1-2 days for app registration, OAuth client-credentials handling, and CVRF parsing. Through Jentic: under an hour — search, load schema, execute.

FAQs

Specific to using Cisco PSIRT openVuln API API through Jentic.

Why is there no official OpenAPI spec for Cisco PSIRT openVuln API?

Cisco does not publish an OpenAPI specification for the PSIRT openVuln API. Jentic generates and maintains this spec so that AI agents and developers can call Cisco PSIRT openVuln API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Cisco PSIRT openVuln API use?

It uses OAuth 2.0 client-credentials. You register an application at apiconsole.cisco.com to obtain a client_id and client_secret, exchange them for a bearer token at https://cloudsso.cisco.com/as/token.oauth2, and send the token as Authorization: Bearer <token>. Through Jentic, the client_id and client_secret stay in the MAXsystem vault.

Can I look up Cisco advisories by a public CVE ID?

Yes. GET /security/advisories/cvrf/cve/{cve_id} returns the CVRF advisory matching that CVE, including affected Cisco products, severity, and fixed releases. There is also an OVAL equivalent at /security/advisories/oval/cve/{cve_id} for scanner-friendly output.

What are the rate limits for the Cisco PSIRT openVuln API?

The OpenAPI spec does not declare explicit rate limits. Cisco's documented guidance is to respect 429 responses and back off; for production polling, schedule the /latest/{number} endpoint at most once every few minutes rather than continuous polling.

Can I retrieve advisories that only affect IOS or IOS XE?

Yes. The dedicated GET /security/advisories/ios and GET /security/advisories/iosxe endpoints return advisories affecting those network operating systems specifically, which is more efficient than filtering the full advisory feed.

How do I monitor new Cisco advisories from an AI agent through Jentic?

Run pip install jentic, have the agent search 'list latest Cisco security advisories', load the schema for GET /security/advisories/cvrf/latest/{number}, and execute it on a schedule. Jentic refreshes the OAuth token automatically — the agent only sees the JSON response.
