What set_active_token does on Js Reverse
AI agents use set_active_token to create or update resources in Js Reverse, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Js Reverse environment.
Why set_active_token is rated Medium
This tool modifies application state by changing which authentication token is active. It is reversible (another token can be set as active), and it creates/modifies a configuration state rather than executing code or deleting data. Misuse could lead to API requests being made with an unintended token, potentially accessing unauthorized resources.
From the tool's definition Set a saved token as the active token. The active token is automatically used by api_request when no explicit token is provided.
Attacks that exploit this kind of access
The rule that runs set_active_token safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Js Reverse, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_active_token, this is the rule to start with:
set_active_token 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 Js Reverse, apply this rule, and every set_active_token call is checked against it from then on.
Questions about set_active_token
Set a saved token as the active token. The active token is automatically used by api_request when no explicit token is provided. It is categorised as a Write tool in the Js Reverse MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Js Reverse MCP server in PolicyLayer and add a rule for set_active_token: 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 Js Reverse. Nothing to install.
set_active_token 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 set_active_token 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 set_active_token. 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.
set_active_token is provided by the Js Reverse MCP server (1600822305/js-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
