Get the activity feed for a workspace showing recent comments, @mentions, and content changes. Includes user avatars and note references for each activity item. Useful for monitoring workspace activity and collaboration.
AI agents call get_activity_stream to retrieve information from Fusebase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns historical activity information from the workspace. It performs no data modification, deletion, execution, or financial operations. The blast radius of misuse is minimal—an attacker could only gain visibility into workspace collaboration history, not alter it or cause operational harm. This is a straightforward Read operation.
From the tool's definition get_activity_stream retrieves activity feed data including comments, @mentions, and content changes with user avatars and note references.
Attacks that exploit this kind of access
Get the activity feed for a workspace showing recent comments, @mentions, and content changes. Includes user avatars and note references for each activity item. Useful for monitoring workspace activity and collaboration. It is categorised as a Read tool in the Fusebase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fusebase MCP Server MCP server in PolicyLayer and add a rule for get_activity_stream: 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 Fusebase MCP Server. Nothing to install.
get_activity_stream 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_activity_stream 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_activity_stream. 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_activity_stream is provided by the Fusebase MCP Server MCP server (ryan-haver/fusebase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
