Open a Bear note by title or ID
AI agents call open_note to retrieve information from Bear MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Opening a note retrieves/displays it for viewing. The word 'open' could imply a UI action (Execute), but in the context of a read-focused server described as enabling AI to 'search, read, and browse Bear notes', this most likely displays/retrieves a note without side effects. Confidence is slightly reduced because 'open' can sometimes trigger external application actions.

Attacks that exploit this kind of access
Open a Bear note by title or ID. It is categorised as a Read tool in the Bear MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bear MCP Server MCP server in PolicyLayer and add a rule for open_note: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Bear MCP Server. Nothing to install.
open_note is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the open_note 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.
Set action: deny in the PolicyLayer policy for open_note. 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.
open_note is provided by the Bear MCP Server MCP server (quanticsoul4772/bear-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
