Get detailed schema information for a specific table
AI agents call get_table_schema to retrieve information from MCP Document Converter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves structural metadata about a database table (column names, types, constraints, etc.) without modifying, deleting, or executing any code. It is a standard introspection operation. The presence of other tools like 'execute_postgresql_query' and 'execute_sql_query' on the same server indicates those handle mutations and execution; this tool is clearly confined to read-only inspection.
From the tool's definition Tool name and description indicate retrieval of schema metadata: 'Get detailed schema information for a specific table'. The verb 'Get' and the read-only nature of schema inspection confirm this is a data query operation with no side effects.
Attacks that exploit this kind of access
Get detailed schema information for a specific table. It is categorised as a Read tool in the MCP Document Converter MCP Server, which means it retrieves data without modifying state.
Register the MCP Document Converter 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 Document Converter. 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 Document Converter MCP server (kittolau/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
