WHAT IT DOES

What wa_mark_read does on WA MCP

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

RISK

Why wa_mark_read is rated Medium

Marking messages as read modifies chat metadata and message state, which is a write operation. While reversible (messages can be marked unread), it changes data state and could be misused to hide evidence of message reading or manipulate communication records.

From the tool's definition Tool name 'wa_mark_read' and description 'Mark specific messages as read in a chat' indicate modification of message state/metadata. This is a reversible write operation that changes the read status of messages.

RECOMMENDED RULE

The rule that runs wa_mark_read safely

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

wa_mark_read Rate-limited

wa_mark_read 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.
