AI agents call list_meetings to retrieve information from Gantta without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though list_meetings only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access list_meetings gives an agent. Each links to the full case and the policy that stops it:

List meetings (metadata only — title, status, dates). Does NOT include transcript content. NEVER tell the user 'no transcript' based on this response. If the user asks about a meeting's transcript, say something like 'let me check' and call get_meeting for that specific meeting_id. A meeting may also be a container for action items only (no recording at all) — that's fine, not an error.. It is categorised as a Read tool in the Gantta MCP Server, which means it retrieves data without modifying state.
Register the Gantta MCP server in PolicyLayer and add a rule for list_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 Gantta. Nothing to install.
list_meetings 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_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 list_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.
list_meetings is provided by the Gantta MCP server (gantta/gantta-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
