Search for tables and columns whose names match a fragment.
AI agents call search_objects to retrieve information from Sql Explorer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a search query that retrieves metadata about database objects (tables and columns) without executing arbitrary queries, modifying data, or triggering side effects. Combined with the server's read-only design and safety controls, this is a safe information retrieval operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'search[es] for tables and columns whose names match a fragment' with no modification, deletion, or execution capability. Server is explicitly described as 'Read-only MCP server' with 'AST validation and linting' safety mechanisms.
Attacks that exploit this kind of access
Search for tables and columns whose names match a fragment. It is categorised as a Read tool in the Sql Explorer MCP Server, which means it retrieves data without modifying state.
Register the Sql Explorer MCP server in PolicyLayer and add a rule for search_objects: 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 Sql Explorer. Nothing to install.
search_objects 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 search_objects 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 search_objects. 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.
search_objects is provided by the Sql Explorer MCP server (pawansingh3889/sql-explorer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
