// MCP TOOL REFERENCE

transform_card

Transform an Adaptive Card: upgrade/downgrade version, apply host-specific constraints, or flatten nesting.

Part of the Adaptive Cards MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke transform_card to trigger processes or run actions in Adaptive Cards. 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.

// WHY ENFORCE A POLICY ON TRANSFORM_CARD

transform_card can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

// FAQ

What does the transform_card tool do? +

Transform an Adaptive Card: upgrade/downgrade version, apply host-specific constraints, or flatten nesting.. It is categorised as a Execute tool in the Adaptive Cards MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on transform_card? +

Add a rule in your Intercept YAML policy under the tools section for transform_card. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Adaptive Cards MCP server.

What risk level is transform_card? +

transform_card is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit transform_card? +

Yes. Add a rate_limit block to the transform_card 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.

How do I block transform_card completely? +

Set action: deny in the Intercept policy for transform_card. 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.

What MCP server provides transform_card? +

transform_card is provided by the Adaptive Cards MCP server (adaptive-cards-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
