Get the schema information for a specific table including column details
AI agents call get_table_schema to retrieve information from Mcp Sqlite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns schema metadata (column definitions, types, constraints) from a SQLite table. It has no side effects, does not execute arbitrary queries, and does not modify data. It is purely informational, matching the 'Read' category for data retrieval operations.
From the tool's definition Tool name 'get_table_schema' and description 'Get the schema information for a specific table including column details' indicate a read-only operation that retrieves metadata about database structure without modifying or executing arbitrary code.
Attacks that exploit this kind of access
Get the schema information for a specific table including column details. It is categorised as a Read tool in the Mcp Sqlite MCP Server, which means it retrieves data without modifying state.
Register the Mcp Sqlite MCP server in PolicyLayer and add a rule for get_table_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 Mcp Sqlite. Nothing to install.
get_table_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_table_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_table_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_table_schema is provided by the Mcp Sqlite MCP server (mcp-sqlite). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
