What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 4 of 74 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.
- list_endpoints
- mcp_servers_sample
- llm_pricing_sample
- api_directory_sample
Tools
Passed: 74 tools listed.
Passed: Every tool describes its inputs with a valid schema.
Protocol
Note: Protocol version 2025-06-18.
Passed: The MCP handshake works (Streamable HTTP).
Passed: Unknown requests are refused.
Connection
Passed: The server responds.
Tools (74)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
