AI agents call list_teams to retrieve information from Filevine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organisational team information without creating, modifying, deleting, or executing any actions. It is a straightforward data retrieval operation with no side effects, fitting the Read category. Severity is low because exposure of team roster information, while potentially sensitive, is typically a lower-risk information disclosure compared to financial, destructive, or execution capabilities.
From the tool's definition Tool name and description: 'list_teams' — 'List all teams in the organisation.' The verb 'list' and the read-only nature of querying team membership data without modification or side effects.

Register the Filevine 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 Filevine. 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 Filevine MCP server (rosenadvertising/filevine-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
