Get the schema (column definitions) for a specific table. Use this to understand what columns are available before querying.
AI agents call get_schema to retrieve information from EdgeLake MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward schema inspection tool that queries metadata about table structure. It enables data exploration and understanding but does not modify, delete, execute code, or move data. It falls squarely in the Read category with low severity because schema information is typically non-sensitive and the tool has no destructive or operational impact.
From the tool's definition Tool description explicitly states it retrieves schema/column definitions for understanding table structure. Action is 'Get' with no modification, deletion, or execution capability. Pure metadata retrieval with no side effects.
Attacks that exploit this kind of access
Get the schema (column definitions) for a specific table. Use this to understand what columns are available before querying. It is categorised as a Read tool in the EdgeLake MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EdgeLake MCP Server MCP server in PolicyLayer and add a rule for get_schema: 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 EdgeLake MCP Server. Nothing to install.
get_schema 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 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. 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 is provided by the EdgeLake MCP Server MCP server (tom-viviano/edgelake-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
