# 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. Agent View of the PolicyLayer registry record for `set_active_token`. HTML page: https://policylayer.com/tools/1600822305-js-reverse-mcp/set-active-token ## Facts - Tool: `set_active_token` - Server: Js Reverse (`1600822305/js-reverse-mcp`) — https://policylayer.com/tools/1600822305-js-reverse-mcp.md - Homepage: https://github.com/1600822305/js-reverse-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "set_active_token", "arguments": {} } } ``` ## 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 own definition: "Set a saved token as the active token. The active token is automatically used by api_request when no explicit token is provided." ## Use case 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
