What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 7 of 7 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.
- get_idescat_stats
- get_idescat_stat
- get_idescat_stat_tables
- get_table_metadata
- get_table_data
- get_table_geo
- render_table
