Read the full content of a message. Automatically acknowledges receipt to the sender.
AI agents call read_message to retrieve information from Interagent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves message content from an inter-agent communication system. While it does trigger automatic acknowledgment, this is a read operation with no destructive, financial, or code execution impact. The acknowledgment is a normal side effect of reading messages in a collaborative system.
From the tool's definition Tool name 'read_message' and description 'Read the full content of a message' indicates data retrieval with no side effects beyond automatic acknowledgment of receipt, which is a benign notification.
Attacks that exploit this kind of access
Read the full content of a message. Automatically acknowledges receipt to the sender. It is categorised as a Read tool in the Interagent MCP Server, which means it retrieves data without modifying state.
Register the Interagent MCP server in PolicyLayer and add a rule for read_message: 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 Interagent. Nothing to install.
read_message 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 read_message 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 read_message. 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.
read_message is provided by the Interagent MCP server (signalclaude/interagent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
