What is anlyon.dev?
anlyon.dev is an AI security tool that scans and classifies Model Context Protocol (MCP) servers so engineers can judge the safety of a third-party integration before they install it. It maintains a searchable database of 15,694+ scanned MCP servers and breaks each one down by tool, labelling every tool as read-only, write, irreversible, or destructive so you can see at a glance whether a server merely looks up data or can delete, send, or publish on your behalf. The platform tracks changes and verifies versions over time, and exposes API endpoints for searching, scanning, and comparing servers, which lets teams wire MCP safety checks into their own tooling. It also documents and checks Agent Skills. anlyon.dev is careful about what it claims: it states that a clean scan is a point-in-time check of a tool's definition, not a guarantee about the server's code or runtime behaviour, so it is a triage aid rather than a certification. For developers and AI agents building on Claude and other MCP hosts, it is a practical first stop for best AI for MCP server safety review before anything reaches production.
What is anlyon.dev used for?
Scanning and risk-classifying MCP server tools before installing them, and comparing MCP servers for safety.
How much does anlyon.dev cost?
Pros and cons
Pros
- Classifies every tool as read-only, write, irreversible, or destructive, so capability risk is visible per tool
- Database of 15,694+ scanned MCP servers you can search and compare
- Change tracking and version verification flag when a server's tools shift over time
- API endpoints for searching, scanning, and comparing servers let you automate checks
- Honest about scope: states scans check tool definitions, not code or runtime behaviour
Cons
- Scans are point-in-time checks of tool definitions, not of server code or actual behaviour
- Scope is limited to MCP servers and Agent Skills, not general software supply-chain security
- No pricing published, so cost of API or higher-tier access is unclear
Questions about anlyon.dev
What is anlyon.dev used for?
anlyon.dev scans Model Context Protocol (MCP) servers and classifies each tool they expose as read-only, write, irreversible, or destructive, helping developers assess an integration's risk before installing it.
How many MCP servers has anlyon.dev scanned?
The platform reports a database of 15,694+ scanned MCP servers, each with a per-tool breakdown you can search and compare.
Does a clean anlyon.dev scan guarantee an MCP server is safe?
No. anlyon.dev states that no finding is a point-in-time check of a tool's definitions, not of the server's code or runtime behaviour, so it should be treated as a triage aid rather than a safety guarantee.
Is anlyon.dev free?
The scanning database appears to be a free public resource, but anlyon.dev does not publish pricing for API access or any paid tier, so contact them to confirm.
What are the best alternatives to anlyon.dev?
MCP registries and security scanners such as MCP Inspector, Smithery, and Invariant Labs.
