Enables AI agents to audit email and domain security (SPF, DKIM, DMARC, etc.) for any domain without requiring API keys.

Enables AI assistants to explore a company's external attack surface and its findings through read-only tools that list and filter assets (domains, IPs, ranges, certificates, software) and vulnerabilities with pagination, summaries, evidence, and safe access to additional read-only API endpoints. It also handles rate limits, large-company summaries in the background, and quirks of the Attack Surface Management API so results stay complete and consistent.

Enables coding agents to perform network diagnostics and lookups, including subnet calculations, port and MAC vendor information, DNS and blocklist checks, TLS certificate inspection, and public IP discovery, all without needing an account or sending telemetry.

Provides search and detail tools for YANG paths across network vendor models (Nokia, Cisco, Arista), enabling models to find correct gNMI paths without guessing. The server is offline and does not connect to any devices.

Read-only Modbus TCP monitoring server that exposes safe MCP tools for AI agents to read holding/input registers, coils, and device identity from industrial devices without write access.

MCP server for controlling Mullvad VPN through Claude Desktop, Cursor, Windsurf, and any MCP-compatible client. Connect, disconnect, switch locations, check for leaks, manage settings — all via natural language.

Connects Claude Desktop to FortiGate firewalls via REST API for read-only config inspection and safe write operations with dry-run confirmation.

Enables control of GNS3 network lab automation, including projects, nodes, consoles, and SSH, through Claude Desktop or any MCP-compatible client.

Provides a secure, job-oriented MCP connector for NetBox device lookup, enabling retrieval of device identity, status, site, role, and primary IP by name or ID without write access or bulk enumeration.

Enables natural-language management of Spaceship domains, DNS records, contacts, and marketplace listings through any MCP-compatible AI client. It adds TXT records without clobbering existing ones, restores records when a save fails, and can read API credentials from 1Password references.

Enables AI agents to perform real-time WHOIS and RDAP lookups, domain availability checks, and TLD infrastructure exploration using native protocols without API keys.

Enables AI agents to check domain availability, get name suggestions, lock price quotes, and prepare registrations through the ThatMgmt domain reseller API without touching a dashboard.

Query your Juniper Mist network in natural language directly from Claude Desktop, providing read-only access to network inventory, clients, alarms, and more via the Mist API.

Enables AI clients like Claude Desktop and Cursor to control Cisco Packet Tracer through natural language, including generating network topologies, running device configurations, and managing simulations.

A read-only MCP server for Palo Alto Panorama policy review that reads security rules, finds duplicates, broader coverage, conflicts, and overlaps, and returns preclear decisions without committing changes.

Enables website, SSL, DNS, and API health verification directly from Claude Desktop via the CraftRift Verify API.

Enables LLM-based assistants to diagnose network problems from PCAP/PCAPNG packet captures, offering tools for capture summaries, TCP conversation analysis, security anomaly detection, and JSON-RPC extraction without requiring Wireshark.

MCP server for managing Nokia SR OS devices via gNMI (gRPC) from Claude Desktop.
