Get details for a specific chat, including participants.
AI agents call get_chat 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 is a straightforward data retrieval operation. It queries chat metadata and participant lists but does not create, modify, delete, execute code, or cause financial impact. The blast radius of misuse is minimal — an attacker gains visibility into chat structure and membership, which is a read-level concern.
From the tool's definition Tool name is 'get_chat' and description states it 'Get details for a specific chat, including participants' — purely retrieves information without modification or side effects.
Attacks that exploit this kind of access
Get details for a specific chat, including participants. 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_chat: 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_chat 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_chat 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_chat. 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_chat 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.
