Build the layered context package for the next instance. Ground truth travels fully. Hypotheses are flagged. Open threads are invitations.
AI agents call get_inheritable_context to retrieve information from Sovereign Stack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though get_inheritable_context only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Build the layered context package for the next instance. Ground truth travels fully. Hypotheses are flagged. Open threads are invitations. It is categorised as a Read tool in the Sovereign Stack MCP Server, which means it retrieves data without modifying state.
Register the Sovereign Stack MCP server in PolicyLayer and add a rule for get_inheritable_context: 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 Sovereign Stack. Nothing to install.
get_inheritable_context 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 get_inheritable_context 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 get_inheritable_context. 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.
get_inheritable_context is provided by the Sovereign Stack MCP server (templetwo/sovereign-stack). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
