AgentCloak Data Cloak Skill

AI agent skill for InCountry AgentCloak: runtime PII cloaking/uncloaking via MCP server and environment configuration via Portal API.

Two modes of operation

Mode 1 — On-demand cloaking

Ask the agent to cloak or uncloak a value right now. No code is written or modified. The agent issues a direct call to the MCP server and returns the result.

Cloak the name "Alice Johnson"

Uncloak  with id 

Mode 2 — Code integration

Ask the agent to add PII protection to an existing application. The agent reads the source file, adds a cloak call to the MCP server, and updates the output to display cloaked values instead of originals.

Add PII protection to acme-crm.ts using the AgentCloak MCP server.
Cloak the full names of all customers before printing them.

The application has no knowledge of AgentCloak before the agent touches it.

The agent adds one function and one call to your existing code — no SDK, no new dependencies, just a fetch to the MCP server.
