What write_file_text does on Mapi Agent Memory
AI agents use write_file_text to create or update resources in Mapi Agent Memory, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mapi Agent Memory environment.
Why write_file_text is rated Medium
The tool name explicitly indicates writing to files, a reversible data modification operation. Assigned to Write rather than Execute or Destructive because the name does not suggest code execution or irreversible deletion, though the empty description prevents confirmation of argument constraints.
From the tool's definition Tool name 'write_file_text' indicates file creation or modification. Tool description is empty, limiting assessment precision.
Attacks that exploit this kind of access
The rule that runs write_file_text safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mapi Agent Memory, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For write_file_text, this is the rule to start with:
write_file_text 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Mapi Agent Memory, apply this rule, and every write_file_text call is checked against it from then on.

Register the Mapi Agent Memory MCP server in PolicyLayer and add a rule for write_file_text: 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 Mapi Agent Memory. Nothing to install.
write_file_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the write_file_text 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 write_file_text. 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.
