List all teams.
AI agents call list_teams to retrieve information from Fathom AI MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves team data for enumeration or discovery purposes. It has no side effects, does not modify data, and does not execute external operations. It is consistent with sibling tools like 'list_meetings' and 'list_team_members', which are also read operations. The blast radius is low since it only exposes existing team information.
From the tool's definition Tool name is 'list_teams' and description states 'List all teams.' The verb 'list' is a read-only operation that retrieves data without modification.
Attacks that exploit this kind of access
List all teams. It is categorised as a Read tool in the Fathom AI MCP MCP Server, which means it retrieves data without modifying state.
Register the Fathom AI MCP server in PolicyLayer and add a rule for list_teams: 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 AI MCP. Nothing to install.
list_teams 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 list_teams 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 list_teams. 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.
list_teams is provided by the Fathom AI MCP server (jerichosequitin/fathom-ai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
