Inspect tables, columns, and indexes for the current or specified database.
AI agents call inspect_schema to retrieve information from MCP Server MySQL without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays schema information (tables, columns, indexes) from a database. It performs no modifications, deletions, or code execution—purely informational inspection. The action is read-only with no side effects, making it a Read category risk with low severity.
From the tool's definition Tool name 'inspect_schema' and description 'Inspect tables, columns, and indexes' indicate query/retrieval of database metadata with no modification capability.
Attacks that exploit this kind of access
Inspect tables, columns, and indexes for the current or specified database. It is categorised as a Read tool in the MCP Server MySQL MCP Server, which means it retrieves data without modifying state.
Register the MCP Server MySQL MCP server in PolicyLayer and add a rule for inspect_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 Server MySQL. Nothing to install.
inspect_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 inspect_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 inspect_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.
inspect_schema is provided by the MCP Server MySQL MCP server (nilsir/mcp-server-mysql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
