WHEN AI AGENTS USE THIS TOOL

AI agents call list_tables to retrieve information from Turso without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.

WHY ENFORCE A POLICY ON LIST_TABLES

Even though list_tables only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

tools:
  list_tables:
    rules:
      - action: allow

What does the list_tables tool do?

List all tables in a database. It is categorised as a Read tool in the Turso MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_tables?

Add a rule in your Intercept YAML policy under the tools section for list_tables. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Turso MCP server.

What risk level is list_tables?

list_tables is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_tables?

Yes. Add a rate_limit block to the list_tables rule in your Intercept 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.

How do I block list_tables completely?

Set action: deny in the Intercept policy for list_tables. 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.

What MCP server provides list_tables?

list_tables is provided by the Turso MCP server (mcp-turso-cloud). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
