- 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
- npmNode.js installed (for the npx 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": {
"microtoll": {
"command": "npx",
"args": [
"-y",
"@microtoll/mcp"
]
}
}
}Run this in your terminal
claude mcp add microtoll -- npx -y @microtoll/mcpOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{
"mcpServers": {
"microtoll": {
"command": "npx",
"args": [
"-y",
"@microtoll/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
{
"servers": {
"microtoll": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"@microtoll/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 Microtoll Engine 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 (0.1.3) reached the registry 31 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

@microtoll/mcp
Microtoll Engine inside your coding tool. A Model Context Protocol server (over standard input and output) that Claude Code, Cursor and any MCP host can call for the engine's documentation and for a project scaffold, so an agent can wire the engine in without leaving the editor — and without leaving the machine: the pages are inside the package, nothing is fetched, nothing runs but what is in src/.
Status: published as @microtoll/mcp on npm and listed in the MCP registry as io.github.microtoll/mcp. Apache-2.0. Zero dependencies. Node 24 or later.
Add it to a host
claude mcp add microtoll -- npx -y @microtoll/mcpAny other host takes the same command (npx -y @microtoll/mcp) as a stdio server.
The three tools
| Tool | What it does |
|---|---|
microtoll_search_docs({ query, limit? }) | Full-text search over the documentation — the same pages as microtoll.dev, shipped in generated/docs.json by the repository's docs build so they never drift. Returns page, section and excerpt. |
microtoll_read_doc({ path }) | One page as Markdown, by the path a search result gives (packages/access.html) or from llms.txt. |
microtoll_scaffold({ directory, namespace?, origin?, name? }) | Writes the notes starter into an empty directory: notes.js, page.js, index.html, docker-compose.yml, nginx.conf, package.json, README.md, with the namespace and origin filled in. Writes files and nothing else; refuses a directory that is not empty; never overwrites. The next steps (npm install, docker compose up) come back as text for the person to run. |
Each tool also carries a plain title and the specification's behaviour hints (annotations), which a host may use to decide when to ask the person first. The two documentation tools only read; the scaffold writes files but only adds them (it never deletes or overwrites), and a second call with the same arguments changes nothing; none of the three uses the network.
What it speaks
JSON-RPC 2.0, one message per line: initialize (protocol version 2025-06-18, tools capability), ping, tools/list, tools/call; notifications are acknowledged by silence; a tool's failure is a tool result with isError, a protocol failure a JSON-RPC error. About 120 lines in src/protocol.js, tested against a transcript of what a host sends.
Tests
npm test: the protocol over a real child process, the search and the page reader over the shipped snapshot, the scaffold into a temporary directory (placeholders filled, a non-empty directory refused), and each tool's title and behaviour hints against what the tool does.
