AI agents invoke planner to trigger actions in Ultra 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.
This tool drives multi-step interactive planning sessions that invoke AI models (OpenAI/Gemini via this server) and can dynamically branch and adapt, triggering external AI operations whose effects depend on arguments. It goes beyond simple data retrieval — it executes a reasoning workflow through external AI providers.

Documented attack patterns abuse exactly the kind of access planner gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ultra MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for planner:
{
"version": "1",
"default": "deny",
"tools": {
"planner": {
"limits": [
{
"counter": "planner_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}planner 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.

Interactive step-by-step planner for breaking down complex tasks and projects. This tool guides you through sequential planning with the ability to revise, branch, and adapt as understanding deepens. Features include forced deep thinking pauses for complex plans (≥5 steps), branching for alternative approaches, and dynamic step adjustment. Perfect for complex project planning, system design, migration strategies, and architectural decisions. It is categorised as a Execute tool in the Ultra MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ultra MCP server in PolicyLayer and add a rule for planner: 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 Ultra MCP. Nothing to install.
planner is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the planner 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.
Set action: deny in the PolicyLayer policy for planner. 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.
planner is provided by the Ultra MCP server (realmikechong/ultra-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
