WHAT IT DOES

What warm_index does on ACE-MCP

AI agents invoke warm_index to trigger actions in ACE-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why warm_index is rated High

warm_index triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs warm_index safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ACE-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For warm_index, this is the rule to start with:

warm_index Rate-limited

warm_index stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect ACE-MCP, apply this rule, and every warm_index call is checked against it from then on.

FAQ

Questions about warm_index

What does the warm_index tool do? +

Pre-build vector embeddings for a project in the background. It is categorised as a Execute tool in the ACE-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on warm_index? +

Register the ACE MCP server in PolicyLayer and add a rule for warm_index: 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 ACE-MCP. Nothing to install.

What risk level is warm_index? +

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

Can I rate-limit warm_index? +

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

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

warm_index is provided by the ACE MCP server (0215andrewfeng/ace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
