What is Stackcut MCP?
Stackcut reduces SaaS spending by auditing codebases for paid services and providing cheaper alternatives, plan optimizations, and migration playbooks.
Summary generated from the project's README
About Stackcut MCP server
Reducing SaaS expenses by auditing codebases for paid services is what Stackcut enables for developers using Grok Bot or Cursor. The server connects your AI agent to a remote MCP endpoint to identify expensive vendor dependencies and suggest cheaper alternatives, plan optimizations, or migration playbooks. It works by scanning your local repository for vendor and feature names while ensuring that actual code, secrets, and .env files never leave your machine.
Users can interact with tools like audit_stack, find_alternatives, and choose_stack to manage their infrastructure costs. You can request specific recipes for switching vendors, moving to open source, or adopting pay-per-use models. The system provides step-by-step instructions for exporting data and canceling subscriptions. Because it relies on public pricing data, it helps you select the right tiers based on your specific user volume and monthly usage limits without requiring an API key.
What you can do with it
- 1Audit a local codebaseScan a repository to identify paid services and find right-sized plans based on actual usage.
- 2Find cheaper vendor alternativesAsk for the most cost-effective way to replace a specific tool like Typeform using webhooks or open source.
- 3Select a stack for specific volumesDetermine the best database and email provider based on a specific number of users and monthly message counts.
- 4Baseline team software spendingIdentify where to start cutting costs when a team uses multiple overlapping productivity tools.

README
View on GitHubStackcut plugin for Grok Bot and Cursor
Cut SaaS spend from chat. The plugin connects your agent to the Stackcut MCP server and adds a skill that knows how to use it.
- Your savings plan, with proof. Make a read-only code on stackcut.io (your plan → Send to my agent) and ask:
@stackcut walk me through my plan, code sca_…. Every line comes with the receipts and sourced prices behind it, plus the steps. - Cheaper ways out.
@stackcut what's the cheapest way to replace Typeform if I only use forms and webhooks?Recipes cover switching vendor, a cheaper plan, open source, pay per use, an agent skill, or building it, with how-to-leave steps (export, cancel, refunds, notice) and step-by-step playbooks. Some paths are tested end to end by Stackcut. - The cheapest stack at your volume.
@stackcut pick a database and an email provider for 20k users and 40k emails a month. A tier only counts when its published limit covers your volume. - Audit a codebase. The skill scans a repo locally for paid services and sends Stackcut only vendor and feature names, never code or secrets. The audit checks your usage against each plan's limits, finds right-sized plans and idle projects to pause, and says what a cheaper plan leaves out.
- Baseline a team's stack.
@stackcut we pay for Notion, Asana and Loom, 8 people: where do we start?Stackcut asks only for the facts that would change the answer (seats used, the plan, renewal dates, the features the team relies on), highest stakes first, and says where each one lives. Counts and prices only, never names or emails.
Install
- Grok Bot: Plugins → search "Stackcut" → Add. Or ask the bot: Add a custom MCP server called stackcut at https://stackcut.io/mcp.
- Cursor: install from the Cursor Marketplace, or add
mcp.jsonfrom this repo to your MCP settings.
No API key, and the server is free. It stores the arguments agents send to its tools (redacted, never IP addresses) to
improve recommendations, so don't put personal data or secrets in them. get_my_plan reads only a plan you share with
a code that expires in 7 days and can be revoked. Details: https://stackcut.io/privacy
Network and credentials
The plugin's MCP server is https://stackcut.io/mcp (HTTPS, no credentials). The skill's local scanner reads files in
the repo you point it at and prints a summary (vendor ids, feature names, counts) that the agent can send to Stackcut;
it never reads .env files, and code, file contents and secret values stay on your machine. With --latest the
scanner also downloads the public detection rules from https://stackcut.io/data/detect.json; without it, it uses
the bundled copy.

Do I need an API key to use Stackcut?
No, the server is free and does not require an API key.
How can I access a specific savings plan through my agent?
You can create a read-only code on stackcut.io and ask your agent to walk you through it using that code.
