Initiates LeetCode authentication flow. Opens browser to LeetCode login (if possible) and provides instructions for the AI agent to guide the user through manual credential extraction from browser DevTools.
Part of the Interactive Leetcode MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke start_leetcode_auth to trigger processes or run actions in Interactive Leetcode. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
start_leetcode_auth can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

start_leetcode_auth is one of the high-risk operations in Interactive Leetcode. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Initiates LeetCode authentication flow. Opens browser to LeetCode login (if possible) and provides instructions for the AI agent to guide the user through manual credential extraction from browser DevTools.. It is categorised as a Execute tool in the Interactive Leetcode MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for start_leetcode_auth. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Interactive Leetcode MCP server.
start_leetcode_auth is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the start_leetcode_auth rule in your Intercept 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 Intercept policy for start_leetcode_auth. 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.
start_leetcode_auth is provided by the Interactive Leetcode MCP server (@sperekrestova/interactive-leetcode-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
