Part of the Exa Websets MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use create_enrichment 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_enrichment 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 enrichment for a webset. Enrichments automatically extract custom data from each item using AI agents (e.g., 'company revenue', 'CEO name', 'funding amount'). IMPORTANT PARAMETER FORMATS: - options (when format is "options"): MUST be array of objects like [{label: "..."}] (NOT array of strings) Example call (text format): {"websetId": "webset_123", "description": "CEO name", "format": "text"} Example call (options format): {"websetId": "webset_123", "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_enrichment. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Exa Websets MCP server.
create_enrichment 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_enrichment 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_enrichment. 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_enrichment 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.
