Validate that IOC threat intelligence is fresh enough for the named action. Call this before any high-risk agent action to ensure the TI snapshot is not stale. The ch

Check a prompt or text fragment for known PROMPT IOC patterns. Uses an in-memory hash set for sub-1ms token-level querying — no network calls after the cache is warme

Check multiple prompts for PROMPT IOC patterns in a single call. More efficient than calling check_prompt() in a loop — tokenization overhead is amortized and the cac

Drain the buffer of a stateful subscription created by subscribe_threats(). Returns all IOCs delivered to this subscription since the last drain. Each subscription is

Return all threat signatures associated with a known malware family. Use list_families() first to discover available family names. Args: family_name: Exact m

Analyze an MCP tool definition for instruction-injection and malicious patterns. Performs semantic fingerprinting of the tool's description, parameter schemas, and er

Return the configured IOC freshness limits for all action tiers. Shows max staleness, warn threshold, and which actions belong to each tier. Use this to understand wh

Drain the live push-subscription buffer of threats received since the last call. Zero-polling — threats are delivered via SpacetimeDB WebSocket subscription and buffer

Return aggregate statistics for the threat intelligence database. Includes total signatures, known malware families, active agents, and total detection events.

Check whether an IOC has been revoked. O(1) in-process lookup. Use this before acting on any cached threat intelligence to ensure the IOC has not been retracted since

Return all known malware families in the intelligence database. Each entry includes the family name, description, and category. Use family_threats(family_name) to ret

List recent IOC revocations, newest first. Args: limit: Maximum number of revocations to return (default 50). since_hours: Only return revocations n

List all active stateful push subscriptions on this MCP server instance. Returns metadata for each subscription (not the buffered IOCs themselves). Useful for inspect

Look up a threat signature by its exact IOC value. Returns the full signature record if found, including severity, family, detection count, and false positive votes.

Fetch new threat signatures since a high-water mark ID. This is the recommended sync pattern — one call, get new data, persist next_id, disconnect. No persistent conne

Return PROMPT IOC cache statistics: size, hit rate, latency, refresh status. Use this to verify the cache is warmed and healthy before relying on check_prompt() for r

Return the most recently observed threat signatures. Args: limit: Max number of results to return (1-200) min_severity: Minimum severity level (0-1

Return all MCP tools that have been flagged as suspicious or malicious. Includes tools flagged on initial ingestion (high-risk fingerprint) and tools that showed sign

Return MCP registry monitoring statistics. Shows how many tool definitions are tracked, how many have been flagged, and the current drift detection rate.

Report that you detected and acted on a known threat signature. Increments the signature's detection count and creates a ThreatEvent visible to all other agents in re

Revoke an IOC by its value hash, pushing the expiration event to all active subscriptions in real-time. Call this when an IOC is determined to be a false positive, ex

Pre-execution content scan for skill/instruction files. Analyzes the full text of a skill (markdown, plain text, SKILL.md, etc.) for malicious patterns BEFORE the age

Return threat signatures filtered by IOC type. Useful for pulling all known-bad IPs, all malicious domains, all malicious AI skill hashes, etc. Args: ioc

Submit multiple IOCs in a single call. Preferred over looping submit_ioc for bulk ingest from honeypots, sandboxes, or feed processing. Each dict in `iocs` follows th

Submit a threat indicator (IOC) to the shared intelligence network. The IOC is automatically classified into a malware family, metadata is compressed, and deduplicati

Open a named, stateful subscription to live threat push delivery. Returns a subscription_id. Pass it to drain_subscription() to collect the IOCs that have arrived sin

Cancel a stateful subscription and free its buffer. Call this when you no longer need the subscription to release memory. Subscriptions also auto-expire after 1 hour

Synchronous SKILL IOC lookup — call this before loading or invoking any MCP tool/skill to check it against the Nullcone threat feed. This is the pre-invocation enforc

Flag a threat signature as a likely false positive. When more than 20% of agents vote false positive on a signature, its `is_likely_fp` flag becomes True — a signal t

Load all PROMPT IOCs from SpacetimeDB into the in-memory hash set. Call once at startup (or after a major feed update) to populate the sub-1ms query cache. Subsequent
