pairing_status
AI agents call pairing_status to retrieve information from Mcp Signal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve pairing status information without modifying state. The empty description reduces confidence slightly, but the naming convention and context among sibling Read tools (get_status, list_chats, read_messages) strongly indicate this is an informational query. A pairing status check is a passive operation with no side effects.
From the tool's definition Tool named 'pairing_status' on a Signal MCP server with a pattern of Read tools (read_messages, list_chats, get_status, search_messages). The name suggests checking pairing state rather than modifying it.
Attacks that exploit this kind of access
pairing_status. It is categorised as a Read tool in the Mcp Signal MCP Server, which means it retrieves data without modifying state.
Register the Mcp Signal MCP server in PolicyLayer and add a rule for pairing_status: 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 Signal. Nothing to install.
pairing_status 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 pairing_status 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 pairing_status. 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.
pairing_status is provided by the Mcp Signal MCP server (sealjay/mcp-signal). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
