Tools & capabilities

Leetcode MCP Server tools 9

  • get_daily_challengeRetrieves 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_problemRetrieves 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_problemsSearches 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_profileRetrieves 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.
  • get_recent_submissionsRetrieves 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_submissionsRetrieves 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_rankingRetrieves 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_solutionsLists 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_solutionRetrieves 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.

Ocular tools 8

  • analyze_imageAnalyze a general image and return structured JSON for a coding agent.
  • extract_text_from_imageExtract OCR text from screenshots, documents, tables, terminal output, or code images.
  • analyze_ui_screenshotAnalyze a webpage, app, UI, or design mockup screenshot for frontend implementation work.
  • diagnose_error_screenshotAnalyze error, terminal, console, browser, or build failure screenshots.
  • compare_ui_screenshotsCompare two UI screenshots and return implementation-useful visual differences.
  • extract_table_from_imageExtract visible table data from an image as structured JSON, Markdown, or CSV-oriented output.
  • analyze_chart_imageAnalyze a chart image and return labels, trends, approximate values, and limitations.
  • create_upload_sessionReturns upload instructions for the binary side channel (use this to analyze LOCAL image files without base64 corruption). Before uploading, verify the local file exists and is non-empty with Bash (e.g. `ls -la <path>` or `test -f <path> && stat -c %s <path>`). Then PUT the raw bytes to the returned upload_url with curl --data-binary (NOT base64); the response gives a file_id to pass to any vision tool. Stateless -- call once to learn the endpoint.
