WHAT IT DOES

What message does on OpenClaw

AI agents use message to create or update resources in OpenClaw, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OpenClaw environment.

RISK

Why message is rated Medium

The tool performs write operations (sending and managing messages), which is reversible and creates/modifies data in a channel. It also has read capability (reading messages), but the write operations dominate the classification.

From the tool's definition Tool description states it can 'send, read, and manage channel messages' — the send and manage operations constitute data creation and modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs message safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OpenClaw, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For message, this is the rule to start with:

message Rate-limited

message stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about message

What does the message tool do? +

Send, read, and manage channel messages. It is categorised as a Write tool in the OpenClaw MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on message? +

Register the OpenClaw MCP server in PolicyLayer and add a rule for 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 OpenClaw. Nothing to install.

What risk level is message? +

message is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit message? +

Yes. Add a rate_limit block to the 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.

How do I block message completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides message? +

message is provided by the OpenClaw MCP server (openclaw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
