Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
openbci_boardB

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.

openbci_exportA

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

openbci_helpA

Discovery and usage guide for openbci-mcp.

OPERATIONS:

  • overview: Tool catalog and board keys.

  • quickstart: Typical Cyton USB workflow.

  • ports: Fleet port assignments.

openbci_signalA

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.

openbci_streamA

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).

openbci_triggerC

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).

agentic_openbci_workflowA

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"], )
