# neuron_cancel_subscription Cancel the current active subscription. Access continues until the end of the current billing period. Agent View of the PolicyLayer registry record for `neuron_cancel_subscription`. HTML page: https://policylayer.com/tools/io-github-conquext-neuron/neuron-cancel-subscription ## Facts - Tool: `neuron_cancel_subscription` - Server: Neuron (`neuron-mcp-server`) — https://policylayer.com/tools/io-github-conquext-neuron.md - Install: `npx -y neuron-mcp-server` - Homepage: https://github.com/conquext/neuron - Risk category: Financial (Critical risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Approval-gated ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "neuron_cancel_subscription", "arguments": {} } } ``` ## Why neuron_cancel_subscription is rated Critical Cancelling a subscription is a financial action that ends a recurring payment obligation. While access continues until the billing period ends, the cancellation itself is a committed financial decision that cannot be undone (the subscription is terminated). This falls squarely in the Financial category due to its impact on billing and service agreements. From the tool's own definition: "'Cancel the current active subscription' — directly terminates a financial subscription agreement" ## Use case AI agents use neuron_cancel_subscription to commit financial operations through Neuron, usually the final step of a payment, billing, or trading workflow. A call moves real money. ## Recommended policy (PolicyLayer) Verdict: **Approval-gated**.
