About FastSpring MCP Server
Connect your FastSpring account to any AI agent and take full control of your digital commerce, global payments, and subscription management through natural conversation.
The OpenAI Agents SDK auto-discovers all 10 tools from FastSpring through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns — chain multiple agents where one queries FastSpring, another analyzes results, and a third generates reports, all orchestrated through the Vinkius.
What you can do
- Order & Transaction Auditing — Retrieve explicit cloud logs tracing order limits and resolve if customers successfully passed fraud filtering natively
- Subscription Orchestration — Inspect deep internal arrays for renewals, check currency applications, and handle ad-hoc charges or plan updates flawlessly
- Account Management — Identify and update bounded CRM records, managing customer emails and profile data across the headless FastSpring platform
- Churn Control — Irreversibly vaporize explicit validations to cancel managed subscriptions securely while extracting rich churn reason metadata
- Catalog & Product Navigation — Retrieve exact structural matching for configured packages and verify which digital products are active in your store
- Authentication Linkage — Dispatch automated validation checks generating ephemeral 24h JWT links for customer portal access securely
- Revenue Recovery — Execute bulk iterations to manually trigger subscription renewals and manage MoR revenue arrays synchronously
The FastSpring MCP Server exposes 10 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
