Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server lanternkb for Claude on this computer, in this order: 1) Check uv with uv --version. If it is missing, tell me to install it from https://docs.astral.sh/uv/getting-started/installation/; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "lanternkb": { "command": "uvx", "args": [ "lanternkb", "serve", "--tier", "open" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the lanternkb tools really show up.

Common questions

Is lanternkb safe?

It passed 3 of 3 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 33 days ago, and the latest version (0.1.3) reached the registry 33 days 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?

lanternkb

Private, local search over your own files, for you and the AI tools you choose.

lanternkb indexes the folders you pick and searches them by meaning and by exact words. It runs as a local MCP server for Claude Code and other assistants, with no daemon, no open port and no telemetry. Secrets it detects are redacted before anything is stored, and you decide which folders an assistant that sends results to the cloud may see.

Install

macOS 14 or later on Apple silicon, or Linux, with uv:

uv tool install --managed-python --python 3.12 "lanternkb[embed,ui]"

lanternkb setup # asks for folders and whether an assistant may see them, offers the models, indexes

--python 3.12 matters: without it uv may pick an older Python already on the machine, and the install fails. The install takes about 0.9 GB on macOS, plus about 1.2 GB for the embedding model. uv tool upgrade lanternkb updates it.

Search

lanternkb search "what did the plumber say about the boiler"

lanternkb search "boiler quote" --type pdf,docx --since 30d lanternkb recent # files changed lately lanternkb ui # the settings page, with a search box lanternkb doctor # checks the setup and says what to fix

Run lanternkb setup before connecting an assistant: the server searches the folders you chose there.

Use it from your AI tools

Claude Code:

lanternkb mcp-setup prints a claude mcp add command. Run it.
The server it registers returns files from folders you marked open, and nothing else.
Claude Code can also read files with its own tools, so mcp-setup prints deny rules too. Add them to ~/.claude/settings.json to keep its tools away from your local-only folders and the index.

Codex, Cursor, VS Code, Gemini CLI and any other MCP client: run lanternkb serve --tier open as a stdio server. For Codex, in ~/.codex/config.toml:

[mcp_servers.lanternkb]

command = "lanternkb" args = ["serve", "--tier", "open"]

The user guide has the JSON form the other clients take, and what to watch for.

What it reads

Notes, code, PDFs, Word and OpenDocument files, rich text, saved web pages and subtitles; scanned pages and audio optionally. Plugins can add file types, embedding models and rules for which folder is open (plugins).

Privacy and safety

Every folder is open or local-only, and new folders are local-only.
Credential folders and secret-shaped files are skipped, and a secret scanner redacts what it finds before anything is split up or embedded. A file in which it finds a secret becomes local-only, even in an open folder.
Files are read in sandboxed worker processes that deny by default: sandbox-exec on macOS, Landlock and seccomp on Linux.
Nothing goes over the network except the model downloads you agree to.

The threat model says what is protected and what is not.

How well it works

Tested on a synthetic set of files (three open-source code bases and 654 generated notes) with 330 held-out questions: nDCG@10 0.831, against 0.777 for grooveseek with its reranker and 0.760 for QMD, at about 30 ms a search (about 120 ms with reranking, on an M5 Max). On the hardest held-out test of planted fake secrets, the scanner kept 71.9% out of the index, so treat it as a second line of defence: keep credential folders out of indexed folders, or local-only.

Limits

The secret scanner misses some secrets, and values that read as examples (example, changeme, a , a ${VARIABLE}) are left alone.
On Linux, reranking runs on the CPU at 0.4 to 1 s a search, so it is off until you enable it.
Email, browser history, calendars and contact cards are not indexed.
Scanned PDFs and images need OCR, which is off by default.
