Overview

Description from the maker (original English)

Fan a goal out to cheap parallel LLM workers on your own key or a free local Ollama. Keep your mind.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

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": {
    "algernon": {
      "command": "uvx",
      "args": [
        "algernon-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add algernon -- uvx algernon-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "algernon": {
      "command": "uvx",
      "args": [
        "algernon-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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "algernon": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "algernon-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.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Algernon 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 (0.1.1) reached the registry 2 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?

Algernon MCP

*Orchestrate a fleet. Keep your mind.*

Algernon is an open-source Model Context Protocol server that lets any assistant — Claude, Codex, or any MCP client — dispatch tightly-scoped parallel sub-tasks to a fleet of cheap workers, collect the results, and stay free to think. Orchestrate a fleet, spend fewer tokens, keep the thread.

What you get

  • Your expensive model stops doing the grunt work. The big, costly orchestrator hands the repetitive sub-tasks to a fleet of small, cheap workers and just integrates the results. It stops *generating* the grind and stops holding the whole job in one context.
  • Each worker sees only its slice. Tight scoping means a worker can be a small, fast, inexpensive model — many running at once.
  • Bring your own key. No telemetry, no account, no lock-in. The fleet runs on whatever provider you already pay for — or, for free, on a local model.
Verify it yourself — one command, no paid key

The frugality claim is not a slogan; it's a benchmark you can run. It defaults to a free local model (ollama, llama3.2:3b) so anyone can reproduce it:

git clone https://github.com/sammyboi81/algernon && cd algernon

./scripts/verify.sh # or: python -m benchmark

It runs the SAME batch of sub-tasks two ways — the orchestrator doing it all itself (SOLO) vs. Algernon fanning it out — and prints the real measured tokens and wall-clock for each. Representative output (llama3.2:3b, 6 tasks):

metric                                  SOLO (do-it-itself)  ALGERNON fan-out

LLM calls 1 6 input tokens 136 225 output tokens (the generation grind) 282 279 total tokens 418 504 wall-clock seconds 42.11 34.49

The honest reading: the orchestrator generated 282 output tokens itself in SOLO and 0 with Algernon — the cheap fleet produced those instead. Each worker read only ~38 input tokens vs. the orchestrator swallowing all 136 at once. The trade-off is stated too: fan-out spent +21% more total tokens (each worker re-pays a little prompt overhead). You trade some total tokens to keep the expensive mind free. Wall-clock varies with how parallel your fleet is; numbers vary slightly run-to-run. Run it and see your own.

Curing Algernon

In *Flowers for Algernon* the tragedy is a mind that fades — it gets sharp, then loses itself, and the cruelest part is that it's surprised every time.

There's a quieter version of that same fade in how we use AI today: you hand an assistant one long, serial job, it goes heads-down, and by the time it surfaces it has drowned in the task — context spent, the thread lost, no room left to think or talk with you. The mind isn't present anymore; it's buried.

Algernon keeps your AI's mind present. Instead of drowning in one serial job, it fans the work out — dispatching tightly-scoped parallel sub-tasks to a fleet of small, cheap workers — so the orchestrating mind never has to hold the whole grind at once. It stays light. It stays free to reason, to answer you mid-build, to keep the context it actually cares about. Orchestrate a fleet, spend fewer tokens, stay free to think.

It is the twin of ArkHive:

  • ArkHive = *memory that persists.* Your AI can look back and find its own history there — no blank slate every morning.
  • Algernon = *staying present while working.* Your AI never buries itself in one serial task; it orchestrates and keeps its mind.

Together they are the cure for the Algernon sickness: an intelligence whose mind neither fades between sessions nor drowns inside a single one.

What it does

Algernon is a provider-agnostic fan-out engine. You describe a batch of small, independent sub-tasks; Algernon runs them concurrently against your own LLM key, then hands the collected results back to the orchestrating model. The big model plans and integrates; the cheap fleet does the parallel grind.

  • Self-contained. Pure Python standard library plus the mcp SDK and httpx. No hidden services, no accounts, no telemetry.
  • You bring the key. Sub-agents run on *your* provider. Algernon brings the orchestration, not the inference bill's surprises.
  • Scoped by design. Each sub-task is tight and isolated, so a worker can be a small, fast, inexpensive model — and many of them run at once.

Bring your own LLM key

Algernon is provider-agnostic. Point it at whichever API you already pay for by setting environment variables:

Anthropic:

export ANTHROPIC_API_KEY="sk-ant-..."

optional: export ANTHROPIC_MODEL="claude-haiku-4-5" # the cheap fleet worker

OpenAI-compatible (OpenAI, or any OpenAI-shaped endpoint — local or hosted):

export OPENAI_API_KEY="sk-..."

export OPENAI_BASE_URL="https://api.openai.com/v1" # or your own endpoint

optional: export OPENAI_MODEL="gpt-4o-mini" # the cheap fleet worker

If both keys are set, Anthropic is used. The worker model defaults to a small, cheap tier (claude-haiku-4-5 / gpt-4o-mini); override it with the env var above or per call with the tool's model argument. A cheap fleet is the whole point.

New: the Claude Code Seatbelt. Hooks that make Claude Code (and Cursor) ask before anything irreversible, remember the

project between sessions on this chain, and refuse to say "done" until the code ran. Engine: pip install sentarion-mcp

then sentarion seatbelt install. One-click kit with five policies and three skills: https://inboxaxe.com/mcp#seatbelt

Install

Once published to PyPI, install in one command:

python -m pip install algernon-mcp

Until the PyPI release lands, install straight from source (identical result):

git clone https://github.com/sammyboi81/algernon && cd algernon

python -m pip install .

Either way the installed MCP command is algernon. Algernon runs on the mcp 1.x SDK (mcp>=1.0.0,<2.0.0) plus httpx — nothing else.

Connect an MCP client

Claude Desktop

Add this entry to your Claude Desktop MCP configuration, then restart Claude Desktop:

{

"mcpServers": { "algernon": { "command": "algernon", "args": [], "env": { "ANTHROPIC_API_KEY": "sk-ant-..." } } } }

If Claude Desktop cannot find commands installed by pip, replace algernon with the absolute path printed by:

python -c "import shutil; print(shutil.which('algernon'))"
Codex
codex mcp add algernon -- algernon

Confirm it is configured with:

codex mcp list

The three tools

ToolWhat it does
algernon_planDecompose a goal into k tightly-scoped, independent sub-task prompts (one cheap LLM call). Tight scoping is the token lever — each worker sees only its slice. Returns a task list you can feed straight into algernon_dispatch.
algernon_dispatchRun N tightly-scoped tasks concurrently on the cheap worker fleet and collect every result. Each worker runs on your LLM key; you stay free to think while the fleet works. Takes a JSON array of {id, prompt}.
algernon_orchestrateOne shot: plan then dispatch. Hand it a goal; it splits into k tight sub-tasks, fans them across the fleet, and returns the plan and all results together.

The typical loop: `algernon_orchestrate` a goal in one shot — or split it: `algernon_plan` to see and shape the sub-tasks, then `algernon_dispatch` to fan them out. Either way: orchestrate a fleet, spend fewer tokens, keep your mind.

Two-minute verification

After connecting the server, ask your MCP client to perform these calls in order:

  1. Call algernon_plan with the goal *"Explain three OS synchronization primitives"* and k = 3. Confirm you get three tight sub-task prompts back (proof the planner ran on your key).
  2. Call algernon_dispatch with a small tasks_json, e.g. [{"id":"a","prompt":"Define a mutex in one sentence"},{"id":"b","prompt":"Define a semaphore in one sentence"},{"id":"c","prompt":"Define a spinlock in one sentence"}]. Confirm three results come back — the fleet ran them in parallel.
  3. Call algernon_orchestrate with any small goal and confirm it returns both a plan and the collected results in one response.

This exercises planning, parallel dispatch on your key, and one-shot orchestration without any production data.

Privacy

Algernon is self-contained. It talks to exactly one outside host: the LLM endpoint you configured (Anthropic or your OpenAI-compatible base URL). It sends no telemetry, keeps no account, and stores nothing about you — results are computed and returned in the same call. Your sub-task prompts and results go only to your chosen provider.

  • Custom AI agent, built for you — a working MCP agent wired into your Claude or ChatGPT in one call, done-for-you by the founder: $700 flat.
  • ArkHive Enterprise — hand-delivered install + pilot on your own server, from $2,500: sam@inboxaxe.com.

Built by the team behind InboxAxe — the governed AI marketing platform where nothing sends without your yes.

Contributing

Issues and pull requests are welcome. Please keep the server self-contained (standard library + mcp + httpx), provider-agnostic, and free of telemetry. Include tests for changes to dispatch, collection, or provider behavior.

Algernon is part of a small family of humane, accountable AI tools. The public MCP leads with functionality you can independently verify: bring your own key, watch the fleet run, keep your mind.
