Manage OpenBCI hardware connections via BrainFlow.

OPERATIONS:

• connect: Open session to Cyton, Ganglion, Galea, synthetic, or streaming board.

• disconnect: Release session and stop streams.

• status: Current connection and channel metadata.

• list_ports: Enumerate serial COM ports (Windows/macOS/Linux).

• list_boards: Supported board keys and BrainFlow IDs.

• probe: Quick synthetic-board smoke test.

Route live EEG to external consumers via BrainFlow streamers.

OPERATIONS:

• streamer_add: Pass raw BrainFlow streamer params (see BrainFlow docs).

• streamer_file: Record to CSV via file:// streamer.

• streamer_multicast: Forward to multicast for OpenBCI GUI / custom listeners.

Examples (BrainFlow streamer syntax):

• file://C:/recordings/session.csv

• streaming_board://225.1.1.1:6677

Discovery and usage guide for openbci-mcp.

OPERATIONS:

• overview: Tool catalog and board keys.

• quickstart: Typical Cyton USB workflow.

• ports: Fleet port assignments.

Real-time EEG signal analysis via BrainFlow DataFilter.

OPERATIONS:

• band_power: Delta/theta/alpha/beta/gamma per channel from latest buffer.

• filter: Apply bandpass, lowpass, highpass, or 60Hz notch to one channel.

Control EEG data streaming from a connected OpenBCI board.

OPERATIONS:

• start: Begin streaming samples into BrainFlow buffer.

• stop: Stop streaming (session stays connected).

• snapshot: Return latest EEG samples per channel (requires active stream).

• marker: Insert timestamped marker into stream (P300/speller experiments).

OSC triggers for BCI neurofeedback and osc-mcp downstream apps.

OPERATIONS:

• send_osc: Fire a one-shot OSC message (VRChat, Reaper, osc-mcp listener).

• list_rules: List persisted threshold rules.

• add_rule: Create band-power rule that emits OSC when matched.

• remove_rule: Delete rule by id.

• evaluate: Run rules against current stream band power.

• history: Recent trigger firings.

• fire_test: Test OSC path for a rule or custom address.

Default target: 127.0.0.1:9000 (configure osc-mcp or app listener).

Multi-step OpenBCI workflows via FastMCP sampling (SEP-1577).

Example: agentic_openbci_workflow( workflow_prompt="Connect synthetic board, start stream, compute band power", available_tools=["openbci_board", "openbci_stream", "openbci_signal"], )
