AI agents call get_table_stats to retrieve information from literateMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information (counts, sums, averages, etc.) from a database table. It performs a read-only operation with no side effects, no data modification, no code execution, and no irreversible actions.
From the tool's definition Tool name 'get_table_stats' and description 'Get simple statistics about a table' indicate a retrieval operation that queries and returns aggregate information without modifying data.
Documented attack patterns abuse exactly the kind of access get_table_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and literateMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_table_stats:
{
"version": "1",
"default": "deny",
"tools": {
"get_table_stats": {}
}
}get_table_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get simple statistics about a table. It is categorised as a Read tool in the literateMCP MCP Server, which means it retrieves data without modifying state.
Register the literate MCP server in PolicyLayer and add a rule for get_table_stats: 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 literateMCP. Nothing to install.
get_table_stats 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_stats 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_stats. 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_stats is provided by the literate MCP server (zongmin-yu/sqlite-literature-management-fastmcp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from literateMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
