render · DeckForge MCP: Risk & Policy

WHAT IT DOES

What render does on DeckForge

AI agents use render to create or update resources in DeckForge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DeckForge environment.

WHY IT NEEDS A POLICY

Why render needs a policy

An AI agent can call render faster than any human can review — one bad instruction and it creates or modifies resources in DeckForge by the hundred, each call as confident as the last.

Verdict

render Rate-limited

render stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches DeckForge, so you can run agents against it safely.

FAQ

Questions about render

What does the render tool do? +

render. It is categorised as a Write tool in the DeckForge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on render? +

Register the DeckForge MCP server in PolicyLayer and add a rule for render: 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 DeckForge. Nothing to install.

What risk level is render? +

render is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit render? +

Yes. Add a rate_limit block to the render 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.

How do I block render completely? +

Set action: deny in the PolicyLayer policy for render. 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 render? +

render is provided by the DeckForge MCP server (whatsonyourmind/deckforge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
