Trace decision history backwards through time to see how contexts influenced each other
AI agents call build_causal_chain to retrieve information from Semantic Context MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and traces historical context/decision data without modifying or creating any records. It is a retrospective query that follows causal links between existing contexts, similar to a graph traversal read operation. No side effects are indicated.

Attacks that exploit this kind of access
Trace decision history backwards through time to see how contexts influenced each other. It is categorised as a Read tool in the Semantic Context MCP MCP Server, which means it retrieves data without modifying state.
Register the Semantic Context MCP server in PolicyLayer and add a rule for build_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 Semantic Context MCP. Nothing to install.
build_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 build_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 build_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.
build_causal_chain is provided by the Semantic Context MCP server (semanticintent/semantic-wake-intelligence-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
