Project thoughts into future or past scenarios. Analyze how conclusions change over time.
AI agents call temporal_projection to retrieve information from Deep Thinker without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs cognitive/analytical reasoning by projecting thoughts across temporal scenarios and analyzing how conclusions evolve. It reads and processes existing thought graph data without creating, modifying, executing, or deleting anything. It is a pure analytical/reasoning operation with no external side effects, making it a Read category tool with low severity.
From the tool's definition Project thoughts into future or past scenarios. Analyze how conclusions change over time.
Documented attack patterns abuse exactly the kind of access temporal_projection gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Deep Thinker, and nothing reaches the server without passing your rules. This is the rule we recommend for temporal_projection:
{
"version": "1",
"default": "deny",
"tools": {
"temporal_projection": {}
}
}temporal_projection is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Project thoughts into future or past scenarios. Analyze how conclusions change over time. It is categorised as a Read tool in the Deep Thinker MCP Server, which means it retrieves data without modifying state.
Register the Deep Thinker MCP server in PolicyLayer and add a rule for temporal_projection: 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 Deep Thinker. Nothing to install.
temporal_projection is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the temporal_projection 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 temporal_projection. 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.
temporal_projection is provided by the Deep Thinker MCP server (nachosystems/deep-thinker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Deep Thinker, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
