Get the schema of a table.
AI agents call get_table_schema to retrieve information from MySQL Managing MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves schema metadata (column names, types, constraints) from a table without creating, modifying, or deleting any data. It is a read-only operation with no side effects. The low severity reflects minimal blast radius—an AI agent misusing this tool could only gain information about table structure, not access sensitive data values or modify the database.
From the tool's definition Tool name 'get_table_schema' and description 'Get the schema of a table' indicate retrieval of metadata without modification. The action is querying/retrieving structural information about a database table.
Attacks that exploit this kind of access
Get the schema of a table. It is categorised as a Read tool in the MySQL Managing MCP MCP Server, which means it retrieves data without modifying state.
Register the MySQL Managing 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 MySQL Managing MCP. 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 MySQL Managing MCP server (lclpedro/mcp-mysql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
