Performs multiple related searches simultaneously and returns combined results. Ideal for complex research questions that benefit from being broken down into simpler components. IMPORTANT: Each query should be a natural language question as a complete sentence, NOT keyword lists.
AI agents call sonar_multi_search to retrieve information from Claude TypeScript MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a search/query tool that retrieves information without side effects. It takes natural language questions as input and returns search results, consistent with Read category tools (search, fetch, query). The low severity reflects minimal blast radius—search misuse cannot damage systems or data, though it could return sensitive information if searching private/restricted sources.
From the tool's definition Tool performs searches and returns results. Description states it 'Performs multiple related searches simultaneously and returns combined results' with no mention of data modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access sonar_multi_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude TypeScript MCP Servers, and nothing reaches the server without passing your rules. This is the rule we recommend for sonar_multi_search:
{
"version": "1",
"default": "deny",
"tools": {
"sonar_multi_search": {}
}
}sonar_multi_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Performs multiple related searches simultaneously and returns combined results. Ideal for complex research questions that benefit from being broken down into simpler components. IMPORTANT: Each query should be a natural language question as a complete sentence, NOT keyword lists. It is categorised as a Read tool in the Claude TypeScript MCP Servers MCP Server, which means it retrieves data without modifying state.
Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for sonar_multi_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 Claude TypeScript MCP Servers. Nothing to install.
sonar_multi_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 sonar_multi_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 sonar_multi_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.
sonar_multi_search is provided by the Claude TypeScript MCP Servers MCP server (ukkz/claude-ts-mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude TypeScript MCP Servers, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
