Add a thought to the cognitive graph using the current strategy. Supports sequential, dialectic, parallel, analogical, and abductive reasoning strategies. Each thought becomes a node in a DAG with confidence scoring, edges, and metadata.
AI agents use think to create or update resources in Deep Thinker — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Deep Thinker environment.
This tool creates and modifies data structures (nodes in a directed acyclic graph) representing thoughts during reasoning processes. It is reversible in nature—nodes can be removed or modified without permanent destruction. It does not execute external commands, delete data irreversibly, access financial systems, or retrieve data from external sources.
From the tool's definition The tool description states it "Add[s] a thought to the cognitive graph" and "Each thought becomes a node in a DAG with confidence scoring, edges, and metadata." The verb 'Add' and the phrase 'becomes a node' indicate creation and modification of internal…
Documented attack patterns abuse exactly the kind of access think 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 think:
{
"version": "1",
"default": "deny",
"tools": {
"think": {
"limits": [
{
"counter": "think_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}think 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.

Add a thought to the cognitive graph using the current strategy. Supports sequential, dialectic, parallel, analogical, and abductive reasoning strategies. Each thought becomes a node in a DAG with confidence scoring, edges, and metadata. It is categorised as a Write tool in the Deep Thinker MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Deep Thinker MCP server in PolicyLayer and add a rule for think: 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.
think is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the think 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 think. 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.
think 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.
Free to start. No card required.
