Returns detailed column information for a single table or collection: data types,
AI agents call dlp_describe_table to retrieve information from Database Lookup Protocol (DLP) 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 table structures (column information, data types) without modifying data or executing arbitrary code. It is a read-only inspection operation with minimal blast radius. The server's read-only access guarantee and the tool's function of returning schema details classifies it as Read category with low severity.
From the tool's definition Tool is described as providing 'read-only access' and 'Returns detailed column information for a single table or collection: data types'.

PolicyLayer is an MCP gateway — it sits between your AI agents and Database Lookup Protocol (DLP), and nothing reaches the server without passing your rules. This is the rule we recommend for dlp_describe_table:
{
"version": "1",
"default": "deny",
"tools": {
"dlp_describe_table": {}
}
}dlp_describe_table is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns detailed column information for a single table or collection: data types,. It is categorised as a Read tool in the Database Lookup Protocol (DLP) MCP Server, which means it retrieves data without modifying state.
Register the Database Lookup Protocol (DLP) MCP server in PolicyLayer and add a rule for dlp_describe_table: 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 Database Lookup Protocol (DLP). Nothing to install.
dlp_describe_table 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 dlp_describe_table 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 dlp_describe_table. 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.
dlp_describe_table is provided by the Database Lookup Protocol (DLP) MCP server (kalyangupta12/database-lookup-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Database Lookup Protocol (DLP), add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
