Search the indexed corpus.
AI agents call search 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 search tool retrieves or queries data from an indexed corpus without creating, modifying, deleting, or executing operations. It is a read-only operation that returns search results. The context confirms this is part of an FTS5 (Full-Text Search) backend, which is inherently a retrieval mechanism. No destructive, financial, or code execution capabilities are implied.
From the tool's definition Tool name is 'search' and description states 'Search the indexed corpus.' This is a query operation with no side effects.
Attacks that exploit this kind of access
Search the indexed corpus. 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 search: 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.
search 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 search 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 search. 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.
search 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.
