Chargebee

Exposes Chargebee subscription operations (create, update, cancel, pause) as MCP tools that AI agents can invoke through standardized tool-calling protocols. Implements a schema-based function registry that maps Chargebee API endpoints to agent-callable tools with parameter validation, enabling agents to manage subscription state without direct API knowledge.

Provides MCP tools to fetch customer profiles, subscription history, and billing data from Chargebee and inject this context into agent memory or conversation state. Uses Chargebee's query APIs to retrieve structured customer records and formats them for LLM consumption, enabling agents to make decisions based on current billing state.

Exposes invoice creation, payment processing, and refund operations as MCP tools, allowing agents to issue refunds, create manual invoices, or trigger payment retries through structured tool calls. Implements validation of refund amounts against invoice totals and payment method availability before executing operations.

Provides MCP tools to query Chargebee's plan catalog, pricing tiers, and add-ons, returning structured pricing data that agents can reference when recommending upgrades or explaining billing to customers. Caches plan metadata to reduce API calls and enables agents to reason about plan comparisons.

Exposes coupon creation, validation, and application as MCP tools, allowing agents to generate discount codes, apply coupons to subscriptions, or validate coupon eligibility based on customer attributes. Implements coupon validation logic to prevent invalid discount applications.

Implements MCP server-side event handling to receive Chargebee webhooks (subscription changes, payment failures, invoice generation) and trigger agent actions based on event types. Routes webhook events to agent-callable tools or context updates, enabling reactive automation workflows.

Provides MCP tools to handle multi-currency pricing, localized billing addresses, and regional tax calculations, enabling agents to interact with global customers. Translates pricing and billing data into customer-specific currencies and locales based on customer attributes.

Manages conversation state and customer context across multi-turn agent interactions, storing customer ID, subscription state, and billing context in MCP session memory. Enables agents to maintain context about customer billing history and previous interactions without re-fetching data.

Implements structured error handling for Chargebee API failures, rate limiting, and network issues, providing agents with fallback strategies and graceful degradation. Returns detailed error codes and recovery suggestions to enable agents to handle failures intelligently.
