Part of the Exa Websets MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use create_webset to create or modify resources in Exa Websets. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call create_webset repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Exa Websets.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a new Webset collection. Websets are collections of web entities (companies, people, papers) that can be automatically searched, verified, and enriched with custom data. IMPORTANT PARAMETER FORMATS: - searchCriteria: MUST be array of objects like [{description: "..."}] (NOT array of strings) - enrichments: Each must have description field, optional format and options - enrichment options: MUST be array of objects like [{label: "..."}] (NOT array of strings) Example call: { "name": "AI Startups", "searchQuery": "AI startups in San Francisco", "searchCriteria": [{"description": "Founded after 2020"}], "enrichments": [ {"description": "CEO name", "format": "text"}, {"description": "Company stage", "format": "options", "options": [{"label": "Seed"}, {"label": "Series A"}]} ] }. It is categorised as a Write tool in the Exa Websets MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for create_webset. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Exa Websets MCP server.
create_webset is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_webset 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.
Set action: deny in the Intercept policy for create_webset. 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.
create_webset is provided by the Exa Websets MCP server (exa-labs/websets-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
