특정 노드와 관련된 모든 인과 관계를 조회한다.
AI agents call causal_chain to retrieve information from Brainforge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes existing causal relationships within a knowledge graph. It performs no writes, deletions, or external actions—only queries data. The operation is a standard graph traversal/analysis query with no side effects. Severity is low because misuse would only surface information already stored in the knowledge graph.
From the tool's definition Tool description states '특정 노드와 관련된 모든 인과 관계를 조회한다' (queries all causal relationships related to a specific node). The verb '조회' (to query/retrieve) indicates data retrieval with no modification.
Attacks that exploit this kind of access
특정 노드와 관련된 모든 인과 관계를 조회한다. It is categorised as a Read tool in the Brainforge MCP Server, which means it retrieves data without modifying state.
Register the Brainforge MCP server in PolicyLayer and add a rule for causal_chain: 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 Brainforge. Nothing to install.
causal_chain 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 causal_chain 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 causal_chain. 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.
causal_chain is provided by the Brainforge MCP server (mengro1102/brainforge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
