Connects Claude to TheAlgorithms' 24-language repository collection through their published DIRECTORY.md indexes. You get seven tools: search algorithms by name across languages, list categories and entries per repo, fetch source code with extracted examples (doctests for Python, doc-tests for Rust), compare implementations across languages to spot gaps, and autocomplete algorithm names with a trie-backed suggest. The server auto-discovers languages from the GitHub org and caches indexes locally with ETag validation, fetching file contents on demand. Reach for this when you need working reference implementations during architecture discussions, want to compare algorithmic approaches across ecosystems, or need to pull concrete code examples into context without leaving your editor.

Readme

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.
