WHAT IT DOES

What search_web does on Jina AI Remote MCP Server

AI agents call search_web to retrieve information from Jina AI Remote MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why search_web needs a policy

search_web retrieves information from the web without side effects—it does not create, modify, delete, or execute code. It is a straightforward information retrieval tool analogous to a search engine query. The low severity reflects minimal blast radius: misuse would result in retrieving potentially irrelevant or sensitive public information, but cannot alter systems or commitments.

From the tool's definition Tool performs web search to retrieve and query information ("Search the entire web for current information", "answering questions", "finding resources"). No modification, deletion, execution, or financial transaction capability.

POLICY

How to control search_web

PolicyLayer is an MCP gateway — it sits between your AI agents and Jina AI Remote MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_web:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_web": {}
  }
}

search_web is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Jina AI Remote MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about search_web

What does the search_web tool do? +

Search the entire web for current information, news, articles, and websites. Use this when you need up-to-date information, want to find specific websites, research topics, or get the latest news. Ideal for answering questions about recent events, finding resources, or discovering relevant content. It is categorised as a Read tool in the Jina AI Remote MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_web? +

Register the Jina AI Remote MCP Server MCP server in PolicyLayer and add a rule for search_web: 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 Jina AI Remote MCP Server. Nothing to install.

What risk level is search_web? +

search_web is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_web? +

Yes. Add a rate_limit block to the search_web 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.

How do I block search_web completely? +

Set action: deny in the PolicyLayer policy for search_web. 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 search_web? +

search_web is provided by the Jina AI Remote MCP Server MCP server (jina-ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
