What is the Censys MCP Server?
Connect to Censys and explore the world's largest internet scanning platform through natural conversation.
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
- Host History — View how a host's services and ports have changed over time
- Certificate Search — Find SSL/TLS certificates by issuer, subject, validity and more
- Certificate Details — Get full parsed certificate data by fingerprint
- Certificate Hosts — Find all hosts using a specific certificate
- Aggregation — Analyze distributions of services, countries and ASNs
- Host Diff — Compare two hosts to identify infrastructure differences
How it works
- Subscribe to this server
- Enter your Censys API ID and Secret
- Start exploring internet exposure data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Security Researchers — discover exposed services, track vulnerabilities and analyze attack surfaces
- Sysadmins — monitor their organization's external exposure and identify misconfigurations
- Threat Hunters — track certificate usage, find related infrastructure and identify suspicious hosts
Built-in capabilities (9)
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
Useful for checking remaining API quota and account limits. Get your Censys account information
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
Useful for finding all domains sharing a certificate (SANs). Returns IP addresses, ports and timestamps. Pagination via cursor. Get hosts using a specific certificate
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
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
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
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
Useful for identifying changes between hosts or finding similar infrastructure. Compare two hosts to see differences

Frequently asked questions
How do I get Censys API credentials?
Sign up for a free account at censys.io, go to your account page and generate API credentials. Free tier includes limited queries per day.
What kind of hosts can I find?
Censys scans the entire IPv4 space regularly. You can find web servers, databases, SSH servers, mail servers, IoT devices, industrial control systems and any internet-facing service.
What query syntax is supported?
Censys supports powerful query syntax: service name (services.service_name: HTTP), port (services.port:443), certificate fields (parsed.subject.country: US), OS detection (metadata.os: Linux), ASN, geographic location and boolean operators (AND, OR, NOT).
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
