What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 3 of 3 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.
- search_patents
- get_company_patents
- get_patent_detail
Tools
Passed: 3 tools listed.
Passed: Every tool describes its inputs with a valid schema.
Protocol
Warning: The server only speaks the first MCP version (2024-11-05).
Newer versions (latest 2025-11-25) add tool safety labels, structured output and a safer authorization model.
Passed: The MCP handshake works (Streamable HTTP).
Passed: Unknown requests are refused.
Connection
Passed: The server responds.
Tools (3)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
