At a Glance & Executive Verdict
Leetcode MCP Server
Coding Agents · Local stdio
Quality: 68/100 (Great) | Auth: other
Stellify MCP
Coding Agents · Remote HTTP/SSE
Quality: 51/100 (Good) | Auth: No auth required
Verdict Summary: Choose Leetcode MCP Server if you need specialized Coding Agents tools running via a local process. Choose Stellify MCP if your workspace requires Coding Agents integration with remote web transport. 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).
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.
Build Laravel apps through conversation. Code stored as structured JSON for surgical AI edits.
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, Stellify MCP belongs to Coding Agents using remote streaming HTTP/SSE transport. Select Leetcode MCP Server when you need capabilities focused on coding agents and Stellify MCP 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.
Stellify MCP Tools (32)
get_project
Get the active Stellify project for the authenticated user. **Call this first before any other operations.**
get_directory
Get a directory by UUID to see its contents.
create_directory
Create a new directory for organizing files.
create_file
Create a new file in a Stellify project. This creates an empty file shell - no methods, statements, or template yet.
get_file
Get a file by UUID with all its metadata, methods, and statements.
save_file
Save/update a file with its full configuration. This finalizes the file after `create_file`.
search_files
Search for files in the project by name or type.
create_method
Create a method signature in a file (without implementation).
add_method_body
Parse and add code to a method body. Stellify parses the code into structured JSON statements.
search_methods
Search for methods in the project by name or within a specific file.
create_statement
Create an empty statement in a file. This is step 1 of 2 - you must call `add_statement_code` next.
add_statement_code
Add code to an existing statement. This is step 2 of 2 - call after `create_statement`.
