Get a single scheduled message by its ID.
AI agents call get_scheduled_message to retrieve information from Bluebubbles without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a scheduled message using its ID as a parameter. It performs a simple data lookup operation with no capability to modify, delete, execute code, or trigger financial transactions. The read-only nature and limited scope (single message by ID) result in minimal security impact if misused by an agent.
From the tool's definition Tool name is 'get_scheduled_message' and description states 'Get a single scheduled message by its ID' - the verb 'Get' indicates retrieval of data without modification or side effects.

Get a single scheduled message by its ID. It is categorised as a Read tool in the Bluebubbles MCP Server, which means it retrieves data without modifying state.
Register the Bluebubbles MCP server in PolicyLayer and add a rule for get_scheduled_message: 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 Bluebubbles. Nothing to install.
get_scheduled_message 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 get_scheduled_message 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 get_scheduled_message. 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.
get_scheduled_message is provided by the Bluebubbles MCP server (metaember/bluebubbles-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
