Services / Custom MCP Servers, Claude Plugins and ChatGPT Apps
Custom MCP servers and ChatGPT apps for your business.
A custom MCP server lets AI assistants like Claude and ChatGPT look things up and take actions in your own systems: your bookings, stock, customer records or product. Your team uses it from the AI tools they already have, or your customers find your product inside them.

In short
Red Center Studio builds custom MCP (Model Context Protocol) servers that connect AI assistants such as Claude and ChatGPT to a business's own tools and data, with sign-in, per-user permissions and an activity log, hosted on Cloudflare Workers in the client's own account. It covers internal connectors for a team, public servers and Claude plugins for a product, and ChatGPT apps built on MCP. Builds start from $3,500 USD and usually take 2 to 6 weeks.
Who it is for
- Businesses whose staff already use Claude or ChatGPT and keep copying data in and out of other systems.
- Software products and SaaS businesses that want their product usable from inside AI assistants.
- Teams with a database, booking system, CRM or internal API that an AI assistant should be able to read or update safely.
Sound familiar?
- Our team pastes data into ChatGPT all day, and none of it connects to our real systems.
- We want customers to use our product from Claude or ChatGPT, but we do not know where to start.
- We tried an off-the-shelf connector, but it sees too much or cannot do what we need.
- We need an AI assistant that can take real actions, with clear limits on what it can change.
What changes for you
- Your AI assistant answers from your live data, not from whatever someone pasted in.
- Clear limits: each person sees only what their own account allows, and actions that change data ask first.
- A server you own, in your own Cloudflare account, that works with Claude, ChatGPT and other AI tools that support MCP.
What is included
- A short review of the systems to connect, the questions people will ask and the actions the AI may take.
- A remote MCP server on Cloudflare Workers with the tools you need, each one described so the AI uses it correctly.
- Sign-in with OAuth or API keys, per-user permissions, and read-only tools kept separate from tools that change data.
- Rate limits, input checks and an activity log of every tool call.
- Testing with Claude and ChatGPT, plus written tests for every tool.
- Help preparing a listing for the Claude or ChatGPT directories where your server qualifies.
- Optional per-call pricing for AI agents, set up the same way as an AI Tollbooth.
What you receive
- The MCP server live in your own Cloudflare account, with the code in your repository.
- Connection instructions for Claude, ChatGPT and other MCP clients your team uses.
- A permissions summary: which tools exist, who can use them and what each one can change.
- Handover notes on adding tools, rotating keys and reading the activity log.
Stack
The Model Context Protocol (MCP) over Streamable HTTP, Cloudflare Workers, OAuth sign-in, TypeScript with written tests, and your existing APIs or databases.
What is not included
- Fees charged by AI platforms or app directories.
- Changes to your own systems' APIs, unless they are in the quote.
Price and timeline
From $3,500 USD.
Fixed quote after a short review of the systems to connect and what the AI should be allowed to do. Bigger builds start with a Project Blueprint. Timeline: usually 2 to 6 weeks. Prices are in USD.
How it works
Review, Build, Launch, Care.
- Review. Your systems, the jobs the AI should do and the limits it needs, with a fixed quote.
- Build. The server and its tools, tested against your staging data first.
- Launch. Connected to your team's AI tools, or published for customers, after you approve it end to end.
- Care. Optional Care and Growth Plan from $300 USD per month for updates, new tools and monitoring.

MCP servers and AI apps questions
What is an MCP server?
MCP, the Model Context Protocol, is an open standard that lets AI assistants use outside tools. An MCP server is a small service that gives Claude, ChatGPT or another AI app a set of tools, such as looking up an order or booking a job, that work on your own systems.
Which AI apps can use it?
Claude, ChatGPT and a growing list of AI tools and coding assistants that support MCP. Exactly which plans and apps can add a custom server is set by each provider and changes often, so the review confirms it for the tools your team uses.
Is our data safe?
The server runs in your own Cloudflare account. Each person signs in, sees only what their own account allows, and tools that change data are kept separate and can ask before acting. Every tool call is logged. The AI provider still sees what its user asks and the answers the tools return, so the review covers what should and should not be exposed.
Can you list it in the Claude or ChatGPT directories?
The build includes help preparing a directory listing where your server qualifies. Each directory runs its own review and rules, so a listing cannot be promised.
Can AI agents pay to use it?
Yes, if you want that. Tools can be given a per-call price that AI agents pay, set up the same way as an AI Tollbooth. For most businesses the value is in their own team or customers using it, not per-call fees.
Do you use this yourself?
Yes. WebDesk has a live MCP server that AI agents use to build small business websites, with API keys, prepaid credit packs and job status. It is described at redcenterstudio.com/webdesk/agents/.
