What you can do with it
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
- Connection: Runs on your computer
- Transport: stdio
- Category: Search & AI memory
Install
Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- The registry lists no key to fill in.
You need
- PyPIPython’s uv installed (for the uvx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"thealgorithms": {
"command": "uvx",
"args": [
"thealgorithms-mcp"
]
}
}
}Run this in your terminal
claude mcp add thealgorithms -- uvx thealgorithms-mcpOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"thealgorithms": {
"command": "uvx",
"args": [
"thealgorithms-mcp"
]
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.
Or copy the settings yourself
Paste into .vscode/mcp.json in your project

Common questions
Is Thealgorithms MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.3.1) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.
What can I use instead?

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 syncuv 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 stdiouv 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().
