Part of the Salesforce Marketing MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use sf_update_contact to create or modify resources in Salesforce Marketing. 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 sf_update_contact 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 Salesforce Marketing.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
