Quality: 64/100 (Good) | Auth: other
Verdict Summary: Choose Leetcode MCP Server if you need specialized Coding Agents tools running via a local process. Choose Claude MCP Bridge if your workspace requires Coding Agents integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Leetcode MCP Server when:
You need dedicated capabilities in the Coding Agents domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
Retrieves today's Daily Challenge problem with full description (read-only, no auth). Returns problem details for the current date as JSON. Use get_problem when you know a specific titleSlug; use search_problems to discover problems by filters.
get_problem
Retrieves a single LeetCode problem by titleSlug (read-only, no auth). Returns description, examples, constraints, and metadata as JSON. Use search_problems to find problems by keyword/tag/difficulty; use get_daily_challenge for today's featured problem.
search_problems
Searches LeetCode problems by category, tags, difficulty, and keywords (read-only, no auth). Supports pagination via limit/offset. Returns matching problem list as JSON. Use get_problem when you already know the titleSlug; use this to browse or discover problems.
get_user_profile
Retrieves any user's public profile by username (read-only, no auth). Returns ranking, avatar, bio, submission stats, and platform-specific progress. Use this to look up other users or public stats. Use get_user_status (requires auth) instead to verify the current session user's login state—not for looking up arbitrary users.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Leetcode MCP Server is categorized under Coding Agents and uses a local stdio subprocess. In contrast, Claude MCP Bridge belongs to Coding Agents using local stdio subprocess. Select Leetcode MCP Server when you need capabilities focused on coding agents and Claude MCP Bridge when you require tools for coding agents.
Retrieves a user's recent submission history on LeetCode Global (read-only, no auth). Includes both accepted and failed submissions. Global only—not available on CN. Use get_recent_ac_submissions for accepted-only results, or get_all_submissions (auth, current user) for paginated full history with filters.
get_recent_ac_submissions
Retrieves a user's recent accepted (AC) submissions (read-only, no auth). Available on both Global and CN. Use get_recent_submissions (Global only) to include failed attempts, or get_all_submissions (auth, current user) for full paginated history.
get_user_contest_ranking
Retrieves a user's contest ranking and participation history (read-only, no auth). Returns overall rating, ranking, and per-contest performance as JSON. Use get_user_profile for general stats and ranking; use this specifically for contest performance data.
list_problem_solutions
Lists community solution articles for a problem (read-only, no auth). Returns metadata only (topicId)—not full content. Use get_problem_solution with the returned topicId to read the full article. Do not call this when you already have a topicId and need the solution text.
get_problem_solution
Retrieves full content of a community solution article (read-only, no auth). Requires topicId from list_problem_solutions. Returns article text, author, and metadata as JSON. Use list_problem_solutions first to discover solutions and obtain topicId.
Claude MCP Bridge Tools (5)
query
Execute a prompt via Claude Code CLI with optional file context and session resume. Claude is an AI coding agent that can generate, analyze, refactor, and explain code.
Capabilities: code generation and refactoring, code analysis and explanation, file understanding (text and images), multi-turn conversations via sessionId.
Cost: Default model is Sonnet (~$0.01-0.10/call). Use effort="low" for simple tasks, effort="high" + model="opus" for complex analysis. Set maxBudgetUsd to cap per-call cost (recommended for effort="max" or model="opus").
Tips:
- Set workingDirectory to the target repo for project-aware responses.
- Break complex tasks into focused prompts rather than one large request.
- Resume multi-turn conversations with sessionId from a previous response's metadata.
- Include relevant files via the files parameter for targeted context (text files inlined in prompt, images trigger allowed-tools mode).
- Use noSessionPersistence=true for stateless one-shot calls.
structured
Generate JSON conforming to a provided JSON Schema. Uses Claude CLI's native --json-schema flag for validated output (not client-side validation).
Use for: data extraction from text/files, classification, entity parsing, or any task needing machine-parseable output.
Cost: Similar to query (~$0.01-0.10/call). Schema complexity doesn't significantly affect cost.
Tips:
- Pass the JSON Schema as a JSON string in the schema parameter.
- Schema max size: 20KB. Keep schemas focused for reliable output.
- For extraction tasks, include source text via the files parameter or inline in the prompt.
search
Web search via Claude Code CLI using WebSearch and WebFetch tools. Searches the web and synthesizes a comprehensive answer with source URLs.
Use for: current information, documentation lookups, API references, comparing libraries, and research questions.
Cost: Typically ~$0.02-0.05/search with Sonnet.
Tips:
- Ask specific, focused questions for best results.
- Results include source URLs for verification.
- Use maxResponseLength to control response verbosity.
- Increase timeout for complex research queries that may require multiple web fetches.
listSessions
List active Claude CLI sessions tracked by this server. Returns session metadata (IDs, models, timing, turn counts, cumulative cost) for orchestration. Use to check available sessions before resuming with sessionId. No cost (local lookup only).
ping
Health check: verifies Claude CLI is installed and authenticated, reports versions, capabilities, and configuration. No cost (local check only).
MCP server enabling automated access to LeetCode's programming problems, solutions, submissions and public data with optional authentication for user-specific features (e.g., notes), supporting both leetcode.com (global) and leetcode.cn (China) sites.
Wraps Claude Code CLI as MCP tools (query, search, structured, sessions) with subscription-first auth, cost metadata, budget caps, and granular tool sandboxing.
