AI agents invoke syncContactEnrichment_tool to trigger processes or run actions in Fiber. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
syncContactEnrichment_tool can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Synchronously fetch contact details. USE THIS WHEN: - Get email addresses from LinkedIn profiles - Get phone numbers for contacts DO NOT USE FOR: - Searching for people (use peopleSearch instead) - Company information (use companySearch or kitchenSinkCompany) EXAMPLE: Input: syncContactEnrichment_tool(apiKey="sk_live_...", linkedinUrl="example_string", enrichmentType={}) INPUT SCHEMA: Required parameters: - apiKey (string): Your Fiber API key. Must start with 'sk_live_' or 'sk_test_'. Example: 'sk_live_dR6DxD3HT7oJqTEV' - linkedinUrl (string): Person's LinkedIn URL, like 'https://www.linkedin.com/in/william-h-gates' Optional parameters: - enrichmentType (object): Enrichment types to be requested. Include the ones you want to look for, we will charge credits for the ones you request. For example, { getWorkEmails: true, getPersonalEmails: true, getPhoneNumbers: true } - getWorkEmails (boolean) - getPersonalEmails (boolean) - getPhoneNumbers (boolean) - exhaustive (boolean): If true, we exhaustively fetch all emails and phones for the person. This can be slower and charge more credits. 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 Execute tool in the Fiber MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Fiber MCP server in PolicyLayer and add a rule for syncContactEnrichment_tool: 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 Fiber. Nothing to install.
syncContactEnrichment_tool 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 syncContactEnrichment_tool 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 syncContactEnrichment_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.
syncContactEnrichment_tool is provided by the Fiber MCP server (fiberai/fiber-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
