Execute a SELECT query on the SQLite database.
AI agents call read_query to retrieve information from Mcp Sqlite Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool is explicitly limited to SELECT operations, which are read-only and have no side effects. It cannot modify, delete, or destroy data. The low severity reflects that data retrieval poses minimal risk unless the database contains highly sensitive information, but the tool itself imposes no structural danger.
From the tool's definition Tool name is 'read_query' and description states 'Execute a SELECT query on the SQLite database.' SELECT queries retrieve data without modification.
Attacks that exploit this kind of access
Execute a SELECT query on the SQLite database. It is categorised as a Read tool in the Mcp Sqlite Manager MCP Server, which means it retrieves data without modifying state.
Register the Mcp Sqlite Manager MCP server in PolicyLayer and add a rule for read_query: 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 Mcp Sqlite Manager. Nothing to install.
read_query 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 read_query 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 read_query. 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.
read_query is provided by the Mcp Sqlite Manager MCP server (jonnyhoff/mcp-sqlite-manager). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
