Secfeed

Security Intelligence MCP server — aggregates authoritative vulnerability, news, and threat-intel feeds into a local SQLite database and serves them to AI agents via MCP tools.

Every ingested item is auto-classified against the agent-security-manual threat taxonomy (TH-01..TH-10), so agents can pull an AI-agent-security focused feed and trace each threat to its mitigating controls (CT), requirements (REQ), and manual chapters.

Data sources

Category	Sources
Vulnerabilities	CISA KEV, NVD CVE API 2.0, EPSS, GitHub Security Advisories, GitHub PoC search
Threat intel	Abuse.ch ThreatFox, CISA Cybersecurity Advisories, arXiv cs.CR
News	The Hacker News, BleepingComputer, Krebs on Security, The Record, SANS ISC
Agent security	Simon Willison's blog, Embrace The Red

MCP tools

Tool	Purpose
get_latest_cves	Recent CVEs sorted by EPSS exploit probability
get_cisa_kev	Known Exploited Vulnerabilities (confirmed in-the-wild)
get_security_news	Aggregated security news
search_security	FTS5 full-text search across all data
get_cve_detail	On-demand NVD + EPSS lookup for one CVE
get_threat_summary	24h threat landscape briefing + feed health
get_agent_threat_feed	Items tagged with agent threat classes TH-01..TH-10
lookup_taxonomy	Resolve TH/CT ids to controls, REQs, and manual chapters
get_agent_security_digest	Per-threat-class activity digest for posture review

Agent threat taxonomy

Classification is a deterministic two-tier keyword classifier (taxonomy.py): strong agent-specific patterns always tag; generic security terms tag only when AI/agent context is present in the same text. No LLM calls — results are reproducible and auditable.

ID	Threat class
TH-01	Prompt injection (direct / indirect)
TH-02	Tool abuse / privilege escalation
TH-03	RAG / knowledge-base poisoning
TH-04	Memory / context contamination
TH-05	Agent identity / authority abuse
TH-06	Delegation / multi-agent abuse
TH-07	Supply-chain / MCP / plugin compromise
TH-08	Data exfiltration / secret exposure
TH-09	Audit / evaluation evasion
TH-10	Model / service abuse

Deployment

docker compose up -d --build
docker logs --tail 80 secfeed

• Streamable HTTP: http://<host>:8888/mcp (put a reverse proxy with auth in front for public exposure)
• stdio mode: python3 server.py --stdio
• Data volume: secfeed-data mounted at /data (SQLite + FTS5)

Environment variables

Variable	Purpose
NVD_API_KEY	Optional — higher NVD API rate limits
GITHUB_TOKEN	Optional — higher GitHub API rate limits
SECFEED_DB_PATH	DB path override (default /data/secfeed.db)

Secrets are injected via the compose environment block from the host environment — never commit them.

Development

python3 -m venv venv && venv/bin/pip install -r requirements.txt
SECFEED_DB_PATH=/tmp/secfeed-dev.db venv/bin/python3 server.py --stdio
