Resolve an open thread by its stable thread_id. Preferred when the thread_id is known — avoids ambiguity when multiple threads share keywords.
AI agents use resolve_thread_by_id to create or update resources in Sovereign Stack — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sovereign Stack environment.
An AI agent can call resolve_thread_by_id faster than any human can review — one bad instruction and it creates or modifies resources in Sovereign Stack by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
Resolve an open thread by its stable thread_id. Preferred when the thread_id is known — avoids ambiguity when multiple threads share keywords. It is categorised as a Write tool in the Sovereign Stack MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sovereign Stack MCP server in PolicyLayer and add a rule for resolve_thread_by_id: 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.
resolve_thread_by_id 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 resolve_thread_by_id 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 resolve_thread_by_id. 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.
resolve_thread_by_id 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.
