io.github.cyanheads/cisa-cybersecurity-mcp-serverv0.1.1Security

CISA KEV with BOD 26-04 deadlines, SSVC prioritization, and the ICS advisory corpus (CSAF). Keyless.

The current version, v0.1.1, was published to the official MCP registry on 2026-09-20. It is distributed as @cyanheads/cisa-cybersecurity-mcp-server on npm, filed under Security by this index, and declares 12 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using io.github.cyanheads/cisa-cybersecurity-mcp-server in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Trust verdict · v1 advisory · method

NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-09-20).

Contracts can change after screening, with no version bump. The gate pins io.github.cyanheads/cisa-cybersecurity-mcp-server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

CISA_KEV_REFRESH_CRON

Cron expression for the KEV catalog conditional-refresh poll. HTTP transport only; an empty value disables the in-process schedule.

CISA_CSAF_MIRROR_PATH

Filesystem path to the local SQLite index of ICS advisories.

CISA_CSAF_MIRROR_AUTO_INIT

Seed the ICS advisory index in the background at startup when it has never completed a sync. Accepts true or false; set false where seeding runs out of band.

CISA_CSAF_REFRESH_CRON

Cron expression for the incremental ICS advisory refresh. HTTP transport only; an empty value disables it.

CISA_VULNRICHMENT_CACHE_TTL_SECONDS

Seconds a fetched SSVC record stays cached. Negative results use one sixth of this value.

CISA_FEED_CACHE_TTL_SECONDS

Seconds a parsed RSS feed window stays cached.

CISA_HTTP_TIMEOUT_MS

Per-request timeout in milliseconds for every upstream fetch.

MCP_HTTP_HOST

The hostname for the HTTP server.

MCP_HTTP_PORT

The port to run the HTTP server on.

MCP_HTTP_ENDPOINT_PATH

The endpoint path for the MCP server.

MCP_AUTH_MODE

Authentication mode to use: 'none', 'jwt', or 'oauth'.

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

CISA_KEV_REFRESH_CRON

Cron expression for the KEV catalog conditional-refresh poll. HTTP transport only; an empty value disables the in-process schedule.

CISA_CSAF_MIRROR_PATH

CISA_VULNRICHMENT_CACHE_TTL_SECONDS

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 967,794). Verify it yourself.
