Get information about all tables and columns in the database.
AI agents call get_schema_info to retrieve information from NLP Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves database schema information (tables and columns) for informational purposes only. It has no side effects, cannot modify data, and poses minimal risk even if misused—worst case, an agent discovers schema structure but cannot alter or extract sensitive data without additional write/execute permissions. Classified as Read with low severity.
From the tool's definition Tool name 'get_schema_info' and description 'Get information about all tables and columns in the database' indicate retrieval of schema metadata without data modification. Server description emphasizes 'read-only bridge' and 'safe' access.
Attacks that exploit this kind of access
Get information about all tables and columns in the database. It is categorised as a Read tool in the NLP Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NLP Database MCP Server MCP server in PolicyLayer and add a rule for get_schema_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches NLP Database MCP Server. Nothing to install.
get_schema_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_schema_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_schema_info. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_schema_info is provided by the NLP Database MCP Server MCP server (lisito11/nlp-database-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
