openbci_export · Openbci MCP: Risk & Policy

WHAT IT DOES

What openbci_export does on Openbci

AI agents use openbci_export to create or update resources in Openbci — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Openbci environment.

WHY IT NEEDS A POLICY

Why openbci_export needs a policy

The tool performs a Write operation—it creates or outputs data (exporting EEG/biomedical signals), which is reversible. Without explicit description, confidence is moderate. The blast radius is medium: exporting data could leak sensitive biometric information or create unintended data artifacts, but the operation itself is not destructive, financial, or code-execution in nature.

From the tool's definition Tool name 'openbci_export' indicates data export functionality. In the context of OpenBCI hardware that streams brain signals and processes them, export typically involves writing/saving collected biomedical data to files or external storage.

Verdict

openbci_export Rate-limited

openbci_export stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Questions about openbci_export

What does the openbci_export tool do? +

openbci_export. It is categorised as a Write tool in the Openbci MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What risk level is openbci_export? +

openbci_export is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit openbci_export? +

Yes. Add a rate_limit block to the openbci_export rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block openbci_export completely? +

Set action: deny in the PolicyLayer policy for openbci_export. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides openbci_export? +
