AI agents use export_all_meetings to create or update resources in Fathom MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fathom MCP Server environment.
Exporting all meetings to markdown format is a Write operation—it creates new artifacts (markdown files) from existing meeting data. While non-destructive and read-centric in nature, export functions that generate bulk output are classified as Write due to their potential to create large volumes of data and associated side effects (file creation, storage usage).
From the tool's definition Tool name 'export_all_meetings' and context indicating 'Supports...exporting to markdown' suggest bulk data extraction/export operation. The sibling tool 'export_meeting' exists, and this appears to be its batch variant.
Documented attack patterns abuse exactly the kind of access export_all_meetings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fathom MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for export_all_meetings:
{
"version": "1",
"default": "deny",
"tools": {
"export_all_meetings": {
"limits": [
{
"counter": "export_all_meetings_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}export_all_meetings stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

export_all_meetings. It is categorised as a Write tool in the Fathom MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Fathom MCP Server MCP server in PolicyLayer and add a rule for export_all_meetings: 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 Fathom MCP Server. Nothing to install.
export_all_meetings is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the export_all_meetings 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 export_all_meetings. 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.
export_all_meetings is provided by the Fathom MCP Server MCP server (matthewbergvinson/fathom-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fathom MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
