Execute a read-only SQL query on the configured SQLite database. Only SELECT queries are allowed.
AI agents call query_sqlite to retrieve information from Multi-Tool MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a SQLite database with no side effects. The documented restriction to SELECT queries alone eliminates Write, Execute (in the destructive sense), and Destructive categories. While SQL execution generically could be Execute, the read-only constraint and explicit allowlist of SELECT operations place this firmly in the Read category with low severity.
From the tool's definition Tool description explicitly states "Execute a read-only SQL query" and "Only SELECT queries are allowed." The restriction to SELECT queries means no data modification, deletion, or creation is possible.
Attacks that exploit this kind of access
Execute a read-only SQL query on the configured SQLite database. Only SELECT queries are allowed. It is categorised as a Read tool in the Multi-Tool MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Tool MCP Server MCP server in PolicyLayer and add a rule for query_sqlite: 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 Multi-Tool MCP Server. Nothing to install.
query_sqlite 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 query_sqlite 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 query_sqlite. 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.
query_sqlite is provided by the Multi-Tool MCP Server MCP server (shawn-falconbury/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
