Thealgorithms tools (7)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • compare

    Find the same algorithm across languages — returns only REAL matches.

  • get_algorithm

    Fetch one algorithm by language + repo-relative path (e.g. path='sorts/merge_sort.py').

  • get_category

    List every algorithm in one category (for a language) as {name, path}.

  • list_categories

    List the algorithm categories with entry counts for a language (default: python).

  • list_languages

    List indexed languages (auto-discovered from the TheAlgorithms org) and excluded repos.

  • search_algorithms

    Search one language's algorithms by name/topic. Returns ranked {name, category, path, score}.

  • suggest

    Autocomplete algorithm names by prefix (Trie-backed typeahead).

What the publisher says

From the Thealgorithms repository's README, as published. We do not edit it. Read it on GitHub

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

language accepts names or aliases (cpp/c++, js, ts, …). Typical flow: searchalgorithms("dijkstra", language="rust") → getalgorithm("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().

Nothing above is checked by us. What we check is on the safety report.

Thealgorithms: common questions

Is Thealgorithms MCP server safe?
Mostly: it is graded B (82/100). Read the Thealgorithms safety report
How do I install Thealgorithms?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does Thealgorithms need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Thealgorithms maintained?
The last commit was 157 days ago (2026-05-31). The latest release is v0.3.1.
What can I use instead of Thealgorithms?
Servers from other publishers that do the same job: Jshookmcp MCP server, GitHits MCP server and Bitbybit CAD MCP server.
How does Thealgorithms compare with other Web search MCP servers?
safety score 82/100 (higher than 68% of 3,470 Web search servers); tools 7 (the typical Web search server has 5); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
