Chamber MCP Server

local only

Chamber runs on your own machine — the client starts it, so there is no endpoint to ping. 36 installs a week from npm. Last commit 25 Oct 2026.

Checks a claim's numbers, names and file names against your indexed notes. Local; no model.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add chamber -- npx -y @bu7umaid/chamber
~/Library/Application Support/Claude/claude_desktop_config.json

  "mcpServers": {
    "chamber": {

Optional settings from the registry entry, left out of the block above: CHAMBER_PYTHON (Path to a Python interpreter with onnxruntime, used by the local embedder. Optional: defaults to python3 on PATH; without onnxruntime, semantic search degrades and Chamber says so), CHAMBER_API_KEY (API key for the configured model endpoint. Only read when model.base is not a loopback address; a local endpoint needs no key).

Chamber — questions

Answers built from our own checks of this server.

Why is there no uptime for Chamber?
Chamber runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @bu7umaid/chamber was installed 36 times last week.
How do I connect Chamber?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @bu7umaid/chamber straight from npm; nothing to host, nothing to sign up for.
How many people use Chamber?
The npm package @bu7umaid/chamber was installed 36 times in the last week. Week over week that is -45%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Chamber open source?
Yes — it is published under the MIT licence, written in TypeScript and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
