Read the raw content of a single indexed document.
AI agents call read to retrieve information from Mcp Fts5 Starter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and returns the content of an already-indexed document. It performs a query operation without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an agent could read unintended documents but cannot alter data or trigger external actions.
From the tool's definition Tool name is 'read' and description explicitly states 'Read the raw content of a single indexed document.' This is a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Read the raw content of a single indexed document. It is categorised as a Read tool in the Mcp Fts5 Starter MCP Server, which means it retrieves data without modifying state.
Register the Mcp Fts5 Starter MCP server in PolicyLayer and add a rule for read: 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 Fts5 Starter. Nothing to install.
read 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 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. 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 is provided by the Mcp Fts5 Starter MCP server (zx22413/mcp-fts5-starter). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
