BrainFlow Biosensing Boards MCP Server

tec Unicorn, BrainBit and many more. It covers recording with event markers, EEG band powers and per-electrode signal-quality checks. Its 12 documented tools cover board, streaming.

People who work with board and streaming and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

One of 32 MCP servers published from k-dense-ai/lab-instrument-mcps. Stars and repository activity are shared across all of them. See all 32 →

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-h -- uvx labmcp-brainflow

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-h": {
      "command": "uvx",
      "args": [

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-09-25 - young repo, little track record yet

license Apache-2.0 - declared in the repository

pypi package labmcp-brainflow - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.K-Dense-AI is GitHub-verified and matches the repo owner

Limitations (from the README)

- How the band powers are computed. average_relative comes from BrainFlow's DataFilter.get_avg_band_powers(apply_filter=True): detrend, 48–52 and 58–62 Hz band-stop, 2–45 Hz band-pass, Welch PSD, then bands of 1–4, 4–8, 8–13, 13–30 and 30–50 Hz averaged over channels and normalised to sum to 1. Per-channel values use detrend, a 50/60 Hz notch and a 1–45 Hz 4th-order zero-phase Butterworth (BrainFlow DataFilter), foll

06 · BrainFlow Biosensing Boards FAQ

Is BrainFlow Biosensing Boards still maintained?

Yes - as of 2026-09-30, its last commit was 2026-09-26. We re-verify nightly.

What can BrainFlow Biosensing Boards do?

g. after it was power cycled or a cable was re-plugged), and start continuous acquisition into BrainFlow's ring buffer (the board's radio/LEDs switch on.

How do I install BrainFlow Biosensing Boards?

Run `uvx labmcp-brainflow`. You can also paste the ready-made client config above.

Does BrainFlow Biosensing Boards run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
