List the caller's active subscriptions. Returns id, type, params, created_at, last_fired_at, fire_count for each. Use this to review what you're monitoring before adding more or to find an id to cancel.
AI agents call list_subscriptions to retrieve information from Mcp Gsa Perdiem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
include_inactive | boolean | — | Include cancelled subscriptions in the response (default false). |
Parameters from the server's own tool schema.
This is a Read operation as it queries subscription state and returns informational data. However, the severity is elevated to 'medium' because the params field may expose sensitive configuration details about monitoring or automation workflows, which could be exploited for reconnaissance.
From the tool's definition The tool 'list_subscriptions' returns metadata about active subscriptions including 'id, type, params, created_at, last_fired_at, fire_count' — it retrieves and queries subscription data without modifying or deleting anything.

Register the Mcp Gsa Perdiem MCP server in PolicyLayer and add a rule for list_subscriptions: 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 Mcp Gsa Perdiem. Nothing to install.
list_subscriptions 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_subscriptions 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_subscriptions. 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_subscriptions is provided by the Mcp Gsa Perdiem MCP server (https://gateway.pipeworx.io/gsa-perdiem/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
