What counter_increment does on Frontmcp
AI agents use counter_increment 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 counter_increment is rated Medium
The tool modifies a counter value by incrementing it, which is a write/update operation. It is reversible (the counter could be decremented) and has a limited blast radius — it only affects an internal counter state. No destructive, financial, or execution behavior is described.

Attacks that exploit this kind of access
The rule that runs counter_increment 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 counter_increment, this is the rule to start with:
counter_increment 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 counter_increment call is checked against it from then on.
Questions about counter_increment
Increment the counter using plugin context extension (this.counter). It is categorised as a Write tool in the Frontmcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Front MCP server in PolicyLayer and add a rule for counter_increment: 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 Frontmcp. Nothing to install.
counter_increment 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 counter_increment 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 counter_increment. 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.
counter_increment 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.
