vector_search
Perform vector similarity search using SQLite vector extensions
Part of the Turso MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call vector_search 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 VECTOR_SEARCH
Even though vector_search 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.

FREQUENTLY ASKED QUESTIONS
What does the vector_search tool do?
Perform vector similarity search using SQLite vector extensions. 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 vector_search?
Add a rule in your Intercept YAML policy under the tools section for vector_search. 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 vector_search?
vector_search is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit vector_search?
Yes. Add a rate_limit block to the vector_search 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 vector_search completely?
Set action: deny in the Intercept policy for vector_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.
What MCP server provides vector_search?
vector_search 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.
