Polarity tools (3)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • do_integration_lookup

    Performs a lookup against a specific Polarity integration. Parses entities (IP addresses, domains, hashes, URLs, etc.) from the query string, then queries the specified integration and returns enriched threat intelligence results.

  • list_available_integrations

    Lists all running Polarity integrations accessible to the user, including their name, ID, acronym, version, description, and supported entity types. Call this first to discover which integrations are available before performing lookups.

  • parse_entities

    Parses and extracts entities such as IP addresses, domains, URLs, file hashes, and email addresses from the provided text. Returns typed entity objects with their values and positions.
