Get the list of participants/attendees for a meeting. Returns email addresses of people who were invited to the calendar event.
AI agents call get_meeting_participants to retrieve information from Fellow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves meeting participant information from Fellow.ai's system. It has no side effects, performs no data modifications, and does not execute code or trigger external operations. Exposure of participant email addresses poses minimal risk compared to other capability categories.
From the tool's definition Tool name and description explicitly state 'Get the list of participants/attendees' and 'Returns email addresses'. No modification, deletion, execution, or financial operations are performed. This is a pure data retrieval operation.
Attacks that exploit this kind of access
Get the list of participants/attendees for a meeting. Returns email addresses of people who were invited to the calendar event. It is categorised as a Read tool in the Fellow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fellow MCP Server MCP server in PolicyLayer and add a rule for get_meeting_participants: 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 Fellow MCP Server. Nothing to install.
get_meeting_participants 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_meeting_participants 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_meeting_participants. 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_meeting_participants is provided by the Fellow MCP Server MCP server (liba2k/unofficial-fellow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
