pycti
Python API client for OpenCTI.
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, permissively licensed, has no known vulnerabilities, and is widely used (top 5000 PyPI). Install it if you need to integrate with OpenCTI; the main consideration is ensuring your OpenCTI instance is accessible and that the 18 runtime dependencies align with your environment's constraints.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- An accessible OpenCTI API instance (URL and valid authentication token) is required; the client cannot function without a running OpenCTI server to connect to.
- Low friction installation with a pure-Python wheel distribution.
- The package is actively maintained with a recent release and 9810 repository stars, indicating stable community adoption.

What it is and what it does
Pycti is the official Python client for OpenCTI, a threat intelligence platform developed by Filigran. It abstracts the OpenCTI REST API into Python methods and utilities, allowing developers to query, create, and manage threat intelligence objects (indicators, malware, campaigns, etc.) programmatically. The client is used both by external integrations and by OpenCTI's own internal components.
The package brings together a substantial dependency graph—including boto3 for cloud storage, pika for message queuing, fastapi and uvicorn for async web operations, stix2 for standards-based threat data, and observability tools like prometheus-client and opentelemetry—suggesting it is designed for production environments where threat data flows through multiple systems. It requires Python 3.7 or later and is actively maintained, with its last release 3 days old.
Use it for
- Automate threat intelligence ingestion by querying OpenCTI for indicators, malware profiles, or campaigns and feeding them into your security tools.
- Build custom connectors or enrichment workflows that read from OpenCTI and write results back, leveraging the client's standardized API methods.
- Integrate OpenCTI threat data into SOAR platforms or incident response systems via programmatic API calls rather than manual exports.
- Develop monitoring dashboards or reporting scripts that pull live threat statistics and entity relationships from an OpenCTI instance.
