Part of the Fiber MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call pollBatchContactEnrichment_tool to retrieve information from Fiber without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though pollBatchContactEnrichment_tool only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Poll batch contact enrichment. USE THIS WHEN: - Get email addresses from LinkedIn profiles DO NOT USE FOR: - Searching for people (use peopleSearch instead) - Company information (use companySearch or kitchenSinkCompany) EXAMPLE: Input: pollBatchContactEnrichment_tool(apiKey="sk_live_...", taskId="example_string", cursor="example") INPUT SCHEMA: Required parameters: - apiKey (string): Your Fiber API key. Must start with 'sk_live_' or 'sk_test_'. Example: 'sk_live_dR6DxD3HT7oJqTEV' - taskId (string): The task ID from the start endpoint response Optional parameters: - cursor (['string', 'null']): The cursor from the previous poll response. Omit this if you are polling for the first time. - take (integer): Number of people to take per batch. Default is 100 RETURNS: Response object with keys: output, chargeInfo, warnings COMMON MISTAKES: - Missing apiKey in function call (apiKey is required) - Invalid API key format (must be 18-50 characters) - API key not in request body (always pass as parameter). It is categorised as a Read tool in the Fiber MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for pollBatchContactEnrichment_tool. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Fiber MCP server.
pollBatchContactEnrichment_tool 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 pollBatchContactEnrichment_tool 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 pollBatchContactEnrichment_tool. 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.
pollBatchContactEnrichment_tool is provided by the Fiber MCP server (fiberai/fiber-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
