WHAT IT DOES

What acp_add_cluster does on Ambient Code Platform MCP Server

AI agents use acp_add_cluster to create or update resources in Ambient Code Platform MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ambient Code Platform MCP Server environment.

WHY IT NEEDS A POLICY

Why acp_add_cluster needs a policy

This tool creates or modifies configuration by adding a new cluster. It is a Write operation because it makes persistent changes to system configuration that can be undone (e.g., by removing the cluster). Severity is high because misconfiguration of clusters in a Kubernetes/OpenShift environment could affect authentication, access control, and resource isolation for hosted agent sessions.

From the tool's definition Tool name 'acp_add_cluster' and description 'Add a new cluster to configuration' indicate creation/modification of infrastructure configuration. The action is reversible (cluster can be removed) and affects system configuration state.

Verdict

acp_add_cluster Rate-limited

acp_add_cluster 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.

FAQ

Questions about acp_add_cluster

What does the acp_add_cluster tool do? +

Add a new cluster to configuration. It is categorised as a Write tool in the Ambient Code Platform MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on acp_add_cluster? +

Register the Ambient Code Platform MCP Server MCP server in PolicyLayer and add a rule for acp_add_cluster: 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 Ambient Code Platform MCP Server. Nothing to install.

What risk level is acp_add_cluster? +

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

Can I rate-limit acp_add_cluster? +

Yes. Add a rate_limit block to the acp_add_cluster 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 acp_add_cluster completely? +

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

acp_add_cluster is provided by the Ambient Code Platform MCP Server MCP server (jeremyeder/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
