What is the 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.
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
How it works

Frequently asked questions
Can my agent check if an order passed fraud filtering in FastSpring?
Yes. Use the 'get_order_details' tool. The agent retrieves explicit cloud logs resolving if customers successfully passed fraud checks, providing you with the exact status of any transaction UUID.
How do I generate a customer login link via chat?
Use the 'generate_auth_link' tool. Provide the account ID. Your agent will command the FastSpring API to generate an ephemeral 24h JWT link that grants the customer secure access to their portal without a password.
Can I manually trigger a renewal charge for a subscription through the agent?
Absolutely. Use the 'charge_managed_subscription' tool. Providing the sub ID allows the agent to execute a manual renewal charge via the MoR infrastructure, handling the ad-hoc billing event synchronously.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
