AI agents invoke deep_researcher_start to trigger actions in Exa MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool launches an autonomous AI agent that performs multiple external operations (web searches, crawling, analysis) in a coordinated multi-step workflow. It triggers external operations whose effects depend on arguments, fitting the Execute category. The high severity reflects the broad, autonomous nature of the agent which can crawl arbitrary web pages and conduct extensive research with limited oversight.

Attacks that exploit this kind of access
Start a comprehensive AI-powered deep research task for complex queries. This tool initiates an intelligent agent that performs extensive web searches, crawls relevant pages, analyzes information, and synthesizes findings into a detailed research report. The agent thinks critically about the research topic and provides thorough, well-sourced answers. Use this for complex research questions that require in-depth analysis rather than simple searches. After starting a research task, IMMEDIATELY use deep_researcher_check with the returned task ID to monitor progress and retrieve results. It is categorised as a Execute tool in the Exa MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Exa MCP Server MCP server in PolicyLayer and add a rule for deep_researcher_start: 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 Exa MCP Server. Nothing to install.
deep_researcher_start is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the deep_researcher_start 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 deep_researcher_start. 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.
deep_researcher_start is provided by the Exa MCP Server MCP server (jordyvandomselaar/exa-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
