What is this?

mcp-saas-toolkit is a Model Context Protocol (MCP) server that equips Claude with tools to call popular SaaS APIs on your behalf. Instead of copy-pasting API keys into chat, you configure the server once and then ask Claude things like:

"Onboard a new customer named Alice with email alice@example.com (customer, email, slack announcement)." "Create a payment link for price_1ABC, email it to them, and let me know on Slack when sent." "Open a GitHub issue for the memory leak and assign it to John."

Claude uses the right tools, calls the right APIs, handles failures via built-in retry backoffs, and gives you the result — all within the conversation.

💬 Example Prompts

Once the server is connected, try these multi-tool workflows:

"Look up the Stripe customer with email john@acme.com, check their subscription, and if it's past due, send them an SMS reminder at +15551234567." "We have a prod incident. Open a bug report on the frontend repo, email the on-call at ops@co.com, and drop a red alert in the Slack #engineering channel." "Read my Stripe balance resource, and summarize how we did this week to the #general channel."

🏗️ Architecture & Development

Built with robustness in mind:

Resiliency: All external API interactions are wrapped in an exponential backoff retry handler to safely absorb rate limits and 5xx errors.
Lazy Initialization: SDK clients are booted only when first invoked. Missing API keys will not crash the server but will cleanly surface actionably errors.
Strict Formatting: Input schemas strictly define all expectations. Output always maps to an { success: true, data } envelope.
