dsa-tracker-mcp 1.0.0

MCP server for tracking DSA/LeetCode practice with spaced repetition. Ships with NeetCode 150, supports any custom problem list.

dsa-tracker-mcp

This is an MCP server for tracking your progress through your DSA questions and comes loaded with a default list of Neetcode 150 (any custom DSA problem list can be switched per user) with built-in spaced repetition. Built with FastMCP and SQLite.

Talk to it naturally from Claude: "what should I work on next", "log that I solved Two Sum, confidence 4, took 12 minutes", "how's my progress", "show me my history on Contains Duplicate".

Features

• Spaced repetition — problems you struggle with come back sooner, problems you nail come back later. Schedule is based on how you rated each attempt (gave up / struggled / solved) and your confidence (1-5).
• List-agnostic — ships with the full NeetCode 150 (150 problems, 18 categories) but can load any custom problem list via a JSON file.
• Fuzzy matching — log an attempt with a loosely-typed problem name ("two sum", "contains dupe") and it'll match the right problem.
• Stats & streaks — solved counts, per-category breakdown, daily streak, total time spent.

Tools

Tool	Description
log_attempt	Log an attempt at a problem (status, confidence 1-5, time spent). Schedules the next review.
get_next_problem	Get what to work on next: an overdue review, or the next new problem in order. Optional category filter.
get_stats	Overall progress summary — solved counts, per-category breakdown, streak, total time.
search_problems	Search/filter problems by name, category, difficulty, or status.
get_problem_history	All logged attempts for a given problem, chronological.

Resources

• dsa://progress — current progress snapshot
• dsa://problem-list — full list of tracked problems

Prompts

• daily_review — generates a daily review session based on what's due
• explain_pattern(category) — explains the core pattern/approach for a given category

Environment variables (optional)

Variable	Default	Description
DSA_TRACKER_DB	~/.dsa_tracker_mcp/progress.db	Path to the SQLite database
DSA_TRACKER_PROBLEMS_FILE	(none, uses built-in NeetCode 150)	Path to a JSON file with a custom problem list

Custom problem list format

[
  {
    "name": "Two Sum",
    "category": "Arrays & Hashing",
    "difficulty": "Easy",
    "url": "https://leetcode.com/problems/two-sum/"
  }
]

url and difficulty are optional and will be auto-filled where possible. order_index is assigned automatically based on list order.

Spaced repetition logic

Outcome	Next review
Gave up	1 day
Struggled, confidence ≤ 2	2 days
Struggled, confidence ≥ 3	4 days
Solved, confidence ≤ 3	7 days
Solved, confidence ≥ 4	21 days

get_next_problem prioritizes overdue reviews before suggesting new problems.

Example prompts

• "What should I work on next?"
• "I just solved Valid Anagram, confidence 5, took 6 minutes, log it"
• "How's my progress on Trees?"
• "Show me my history on Two Sum"
• "Give me a daily review"
