thealgorithms-mcp
mcp-name: io.github.mcande21/thealgorithms-mcp
An MCP server for querying the TheAlgorithms org across every language repo — search algorithm implementations and fetch any one with its in-file examples.
Languages are auto-discovered from the org (not a hardcoded list): a repo is indexed when it
publishes a parseable DIRECTORY.md — currently 24 languages (Python, Java, C++, JavaScript,
Rust, C, TypeScript, PHP, Dart, Kotlin, Ruby, R, Scala, Swift, Julia, Haskell, MATLAB, Zig,
Fortran, Nim, Clojure, F#, Jule, aarch64-assembly). Repos without a DIRECTORY.md (Go, C#, Lua,
Solidity, …) are reported by list_languages with their exclusion reason — no silent gaps.
Hybrid design: each repo's DIRECTORY.md index is cached locally (ETag + TTL); file contents are
fetched on demand from raw.githubusercontent.com. The org/language manifest is auto-discovered via
the GitHub API and cached 7 days. No token required (set GITHUB_TOKEN to raise the rate limit).
See DESIGN.md.
Tools
| Tool | Purpose |
|---|---|
list_languages() | Indexed languages (+ counts, aliases) and excluded repos with reasons |
list_categories(language='python') | Categories with entry counts for a language |
search_algorithms(query, language='python', category?, limit=10) | Ranked {name, category, path, score} |
get_category(category, language='python') | Every algorithm in a category |
get_algorithm(path, language='python', include_source=True) | Source + extracted examples |
compare(name, languages?, min_score=90, limit_per_language=1) | Real matches across languages + missing_in |
suggest(prefix, language='python', limit=10) | Trie-backed name autocomplete (dij → Dijkstra) |
language accepts names or aliases (cpp/c++, js, ts, …). Typical flow:
search_algorithms("dijkstra", language="rust") → get_algorithm("src/graph/dijkstra.rs", language="rust").
Examples are extracted where the language has an in-file convention (Python doctests, Rust
doc-tests); other languages return source plus a note.
Install
From PyPI (recommended):
{ "thealgorithms": { "command": "uvx", "args": ["thealgorithms-mcp"] } }
From GitHub:
{ "thealgorithms": {
"command": "uvx",
"args": ["--from", "git+https://github.com/mcande21/thealgorithms-mcp", "thealgorithms-mcp"] } }
From a local checkout (development):
uv sync
uv run thealgorithms-mcp # serves over stdio
Add any of the above to ~/.normandy-generic/mcp.json (or your MCP client config).
Verify
uv run python scripts/verify_stdio.py # multi-language contract over stdio
uv run python scripts/verify_language.py rust # one language, end-to-end
The harness spawns the server over stdio and asserts every tool against the live org, including
binary-search fetch across ≥8 languages and cross-language compare().
