About Censys MCP Server
Connect to Censys and explore the world's largest internet scanning platform through natural conversation.
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use Censys tools. Connect 9 tools through the Vinkius and assign role-based access — a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.
What you can do
- Host Search — Search internet-facing hosts by service, port, OS, location and more
- Host Details — Get comprehensive info on any IP including all services and certificates

Why Use AutoGen with the Censys MCP Server
AutoGen provides unique advantages when paired with Censys through the Model Context Protocol.
Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use Censys tools to solve complex tasks
Role-based architecture lets you assign Censys tool access to specific agents — a data analyst queries while a reviewer validates
Human-in-the-loop support: agents can pause for human approval before executing sensitive Censys tool calls
Code execution sandbox: AutoGen agents can write and run code that processes Censys tool responses in an isolated environment
Censys + AutoGen Use Cases
Practical scenarios where AutoGen combined with the Censys MCP Server delivers measurable value.
Collaborative analysis: one agent queries Censys while another validates results and a third generates the final report
Automated review pipelines: a researcher agent fetches data from Censys, a critic agent evaluates quality, and a writer produces the output
Interactive planning: agents negotiate task allocation using Censys data to make informed decisions about resource distribution
Code generation with live data: an AutoGen coder agent writes scripts that process Censys responses in a sandboxed execution environment
Censys MCP Tools for AutoGen (9)
These 9 tools become available when you connect Censys to AutoGen via MCP:
aggregate_hosts
Groups results by a specified field (e.g. "services.port", "location.country", "autonomous_system.name") and returns bucket counts. Useful for understanding the distribution of services, countries or ASNs matching a query. Aggregate host search results by a specific field
get_account_info
Useful for checking remaining API quota and account limits. Get your Censys account information
get_certificate
Returns the full parsed certificate including subject, issuer, validity, key info, extensions, CT logs and raw PEM data. Get detailed info for a specific certificate by fingerprint
get_certificate_hosts
Useful for finding all domains sharing a certificate (SANs). Returns IP addresses, ports and timestamps. Pagination via cursor. Get hosts using a specific certificate
get_host
Returns all open ports, service banners, TLS certificates, operating system detection, geolocation, autonomous system info and last updated timestamps. Get detailed info for a specific IP address
get_host_history
Shows how the host's services, ports and certificates have changed over time. Returns timestamps, services observed and changes detected. Pagination via cursor. Get historical scan data for a specific IP
search_certificates
Supports query syntax: issuer names, subject fields, serial numbers, validity dates, key algorithms, certificate transparency logs and more. Returns fingerprints, subjects, issuers, validity periods and key info. Search for SSL/TLS certificates
search_hosts
Supports powerful query syntax: service names (e.g. "nginx"), ports (e.g. "services.port:443"), protocols, operating systems, autonomous systems, geographic locations and more. Returns IP addresses, open ports, services, banners and locations. Pagination via cursor. Search for internet-connected hosts
view_host_diff
Useful for identifying changes between hosts or finding similar infrastructure. Compare two hosts to see differences
