What activities-log does on Frontmcp
AI agents use activities-log to create or update resources in Frontmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frontmcp environment.
Why activities-log is rated Medium
This tool creates/writes a new activity log entry for a user. It's a write operation (creating new data) with no indication of irreversibility or financial impact. Misuse could result in false or misleading activity records being injected, hence medium severity.
From the tool's definition "Log a new activity for a user" — creates a new activity record
Attacks that exploit this kind of access
The rule that runs activities-log safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For activities-log, this is the rule to start with:
activities-log 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 Frontmcp, apply this rule, and every activities-log call is checked against it from then on.

activities-log 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 activities-log 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 activities-log. 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.
activities-log is provided by the Front MCP server (agentfront/frontmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
