What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • av_hash_lookup

    CrushAV file reputation, no key needed: look up up to 100 SHA-256 file hashes. For each hash something is known about, returns `knownMalicious` (the source listing it as malware), `malwareName`, `trust` (0-100: how sure CIRCL hashlookup is that this is a published, known-good fil

  • reputation_lookup

    Look up an IP address or a domain against the ThreatCrush community threat database (what every linked ThreatCrush daemon blocked). Returns `listed` (the corroboration bar: independent reporters agree), a 0-100 `score`, severity, reports, reporters, rules and country; a domain is

  • reputation_bulk

    Look up many IPs or domains at once (up to 100 with a free key, 1,000 with Reputation Pro). Results come back in request order; each counts against the daily allowance.

  • redeem_credit_code

    Redeem a ThreatCrush credit code (CR-XXXX-XXXX-XXXX-XXXX) into the signed-in account's credit balance (1 credit = $1.00). Needs the account's session token (`threatcrush login`), not a tc_agent_ key: agent keys belong to a team, not a person.

  • list_invites

    The signed-in account's invites: how many are left of 3, who joined, and whether the bonus credits were paid. Session token only.

  • create_invite

    Create one invite link (each account has 3, single use, 30 days). When a new account joins on it and confirms its email, both get bonus credits. Session token only.

  • findings_list

    Your org's tracked findings from threatcrush scan, pentest and ai-scan (deduped across runs, with a triage status). Default: open + acknowledged. Session token or tc_agent_ key.

  • findings_get

    One tracked finding with its details (code snippet, remediation, evidence), property and history.

  • findings_triage

    Set the status and/or note of up to 500 findings: acknowledged, fixed, false_positive, ignored or open. fixed is reopened by a later run that still sees it; false_positive and ignored never are. Needs write.

  • incidents_list

    Your org's incidents: what `threatcrush investigate --raise`, the daemon (critical detections) and people raised to humans. Filter by host and explicit since timestamp; only teams you can see. Session token or tc_agent_ key.

  • incidents_get

    One incident: linked forensic evidence, recent events from the same observed source IP on its server, block history for that IP, saved AI assessment, multi-person assignees, fix and test progress, work history, recorded resolution/operator, findings, timeline, notes and who was p

  • incidents_update

    Update fix work performed by your assigned agent or human: set multiple assignees, fix status, PR URL, test status and evidence, verification or blocker, and/or add a note. ThreatCrush catalogs the incident and does not execute remediation. Closing requires status fixed with pass

  • incidents_raise

    Raise an incident report (report_version 1: title, severity, source, dedupe_key, summary, verdict, findings, timeline, recommendations, optional team_id/server_id). The same dedupe_key while open updates it; a new incident pages the team by SMS and email once. Reports that contai

  • webhooks_list

    Your org's webhook endpoints (signed Standard Webhooks deliveries, retried for about three days) and the events ThreatCrush emits: detection.created, findings.raised, reputation.changed. Endpoints behind a Webhook alert destination follow your alert rules; the others get every ev

  • webhooks_create

    Add a webhook endpoint (public https URL). Returns the endpoint and its signing secret (whsec_…), shown once.

  • webhooks_update

    Change a webhook endpoint's url, events, description, or switch it on/off (on again clears its failure count).

  • webhooks_delete

    Remove a webhook endpoint and its delivery log.

  • webhooks_test

    Send a signed webhook.test event to one endpoint now and say how it went.

  • webhooks_rotate_secret

    Replace an endpoint's signing secret; the old one stops working at once. Returns the new secret.

  • webhooks_deliveries

    Recent webhook deliveries (status, attempts, last HTTP status/error, payload), for one endpoint or all.

Common questions

Is threatcrush safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?
