ofurkanuygur/tcmb_mcp Write Risk 2/5

AI agents use tcmb_convert_currency to create or modify resources in Tcmb. 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 tcmb_convert_currency 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 Tcmb.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
