Luogu MCP Server - install, status & alternatives [2026]

01 · Install Luogu MCP Server

Claude Code

claude mcp add kaiserunix-luogu-mcp-server --transport http https://luogu-mcp-server.lantangtang54.workers.dev/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "kaiserunix-luogu-mcp-server": {
      "url": "https://luogu-mcp-server.lantangtang54.workers.dev/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as remote - your agent's requests go to luogu-mcp-server.lantangtang54.workers.dev

registry namespace io.github.Kaiserunix is GitHub-verified and matches the repo owner

03 · What Luogu MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can fetch one Luogu problem statement, formats, samples, tags, difficulty, and URL by pid, resolve a Luogu URL, problem id, or title fragment, then fetch the problem, list canonical algorithm topics, aliases, and known tag ids, and find topic practice problems using aliases, tag ids, deduplication, and match reasons.

The 11 tools it gives your agent

Extracted from the project's README - what Luogu MCP Server lets an agent do.

luogu_search_problems: - Search Luogu problems by keyword, topic, title fragment, problem id, and optional Luogu tag ids.
luogu_fetch_problem: - Fetch one Luogu problem statement, formats, samples, tags, difficulty, and URL by pid.
luogu_resolve_problem: - Resolve a Luogu URL, problem id, or title fragment, then fetch the problem.
luogu_find_related_problems: - Mix topic/pain-point recommendations with live keyword search to find related practice.
luogu_list_algorithm_topics: - List canonical algorithm topics, aliases, and known tag ids.
luogu_find_topic_problems: - Find topic practice problems using aliases, tag ids, deduplication, and match reasons.
luogu_search_problem_sets: - Search Luogu training/problem sets by keyword. Supports type: "all"
luogu_fetch_problem_set: - Fetch one Luogu training/problem set and problem summaries by id.
luogu_recommend_problems: - Return seed recommendations from a topic or student pain point.
luogu_get_user_profile: - Fetch public Luogu user profile data by uid.
luogu_get_capabilities: - Report which LeetCode-style route features are available, auth-required, or planned.

Limitations (from the README)

- Luogu endpoints used here are content-only web endpoints, not a formal stability contract. - The server keeps outputs compact and structured for model context control. - Browser automation is intentionally not the default path. A Playwright fallback can be added later for pages that cannot be read through lightweight HTTP. - For broad topic discovery, Luogu training-set search is often cleaner than raw problem titl
