Returns table or column metadata for the selected LocalWP site
AI agents call mysql_schema to retrieve information from LocalWP MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about database structure (tables and columns) without creating, modifying, or deleting data. It is a read-only operation that queries schema information. The sibling tools include destructive operations (delete_backup, delete_site_file) and write operations (db_import, backup_site), but mysql_schema itself only returns metadata.
From the tool's definition Tool name 'mysql_schema' and description 'Returns table or column metadata' indicate retrieval of schema information with no modification or side effects.
Attacks that exploit this kind of access
Returns table or column metadata for the selected LocalWP site. It is categorised as a Read tool in the LocalWP MCP MCP Server, which means it retrieves data without modifying state.
Register the LocalWP MCP server in PolicyLayer and add a rule for mysql_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 LocalWP MCP. Nothing to install.
mysql_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 mysql_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 mysql_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.
mysql_schema is provided by the LocalWP MCP server (kazimshah39/localwp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
