Get a thread with all messages
AI agents call get_thread to retrieve information from Mcp Coordinator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing thread data and messages without side effects. It performs no write, execute, destructive, or financial operations. The low severity reflects minimal blast radius — retrieving thread state poses no direct harm even if misused by an agent, though it may expose coordination metadata.
From the tool's definition Tool description states 'Get a thread with all messages' — a retrieval operation with no modification, creation, or deletion. The verb 'Get' indicates a read-only query.

Attacks that exploit this kind of access
Get a thread with all messages. It is categorised as a Read tool in the Mcp Coordinator MCP Server, which means it retrieves data without modifying state.
Register the Mcp Coordinator MCP server in PolicyLayer and add a rule for get_thread: 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 Mcp Coordinator. Nothing to install.
get_thread 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_thread 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_thread. 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_thread is provided by the Mcp Coordinator MCP server (swoofer/mcp-coordinator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
