What is MyMCP?

The Model Context Protocol (MCP) is the open standard that lets AI assistants such as Claude securely call external tools and APIs. Building an MCP server normally means writing TypeScript or Python, defining JSON schemas, and wiring up a runtime.

MyMCP removes the code. It is a local web app where you:

1. Describe a tool in plain language.
2. Add the input fields your tool needs.
3. Point it at an API, an integration, or a script.
4. Click Connect — and your AI assistant can use it.

It is built for people who know what they want their AI to do, but would rather not become backend engineers to make it happen: manual testers, product and project managers, business analysts, team leads, and AI power users.

Everything runs locally. No accounts, no cloud, no SaaS — your tools and secrets never leave your machine.

Features

• No-code Tool Wizard. Create AI tools step by step: name, AI-facing description, input fields, action. The JSON Schema is generated for you.
• Three ways to power a tool. Call any REST API, reuse a saved integration, or run a JavaScript / Python script for advanced cases.
• Built-in integrations. Jira, GitHub, Slack, Notion, and generic REST, with stored credentials and connection testing.
• One-click connect. MyMCP detects installed clients (Claude Desktop, Cursor, VS Code / Copilot) and writes the config for you. Existing servers are preserved and the previous config is backed up first.
• Manual export. Copy ready-to-paste config snippets for any MCP client.
• Git-friendly projects. Your entire setup is a single project.json file you can version, share, and import.
• Local and private by design. No sign-up, no telemetry, no cloud. Secrets stay on your machine.
• One command to launch. start.bat / start.sh installs everything, boots the server and UI, and opens your browser.

Quick Start

Prerequisite: Node.js 18+ (tested on Node 22).

1. Clone the repository

git clone https://github.com/damiankaniewski/MyMCP.git
cd MyMCP

2. Run the launcher

Windows

start.bat

macOS / Linux

./start.sh

On first run the launcher will:

1. Install all dependencies (root, backend, frontend).
2. Start the backend on http://localhost:3001.
3. Start the web UI on http://localhost:5173.
4. Open your browser automatically.

How it works

MyMCP provides a small set of focused screens:

Screen	Purpose
Dashboard	See your project, tools, and MCP status. Import / export project.json.
New tool	A step-by-step wizard: name, AI description, input fields, action.
Integrations	Connect Jira, GitHub, Slack, Notion, or any REST API (with secrets).
Connect to AI	Copy ready-made config, or auto-connect to Claude Desktop, Cursor, VS Code.

Tool actions

When you create a tool, you choose what it does:

• Call an API — make an HTTP request. Insert field values with {{fieldName}} and secrets with {{secrets.KEY}}.
• Use an integration — reuse a saved connection; auth headers are added for you.
• Run a script — JavaScript or Python (advanced). Your code receives a params object and returns the result.

Example tool

A "Get Public Holidays" tool, built entirely in the UI, compiles down to this in your project.json:

{
  "name": "get_public_holidays",
  "description": "Returns public holidays for a given country and year.",
  "inputSchema": [
    { "name": "country", "type": "text",   "required": true, "description": "Two-letter code, e.g. PL" },
    { "name": "year",    "type": "number", "required": true, "description": "Year, e.g. 2026" }
  ],
  "executionType": "http",
  "executionConfig": {
    "method": "GET",
    "url": "https://date.nager.at/api/v3/PublicHolidays/{{year}}/{{country}}"
  }
}

Your AI assistant now has a get_public_holidays tool it can call on its own.

Connect your AI assistant

Open the Connect to AI screen. There are two ways to connect.

Automatic (recommended)

MyMCP detects which apps are installed and shows a Connect button. One click writes the server straight into that app's MCP config — your existing servers are kept and the previous file is backed up first. Then restart the app (for VS Code, open Copilot Chat in Agent mode).

Manual

Pick the app's tab, click Copy, and paste the snippet into its MCP config file:

{
  "mcpServers": {
    "my-mcp": {
      "command": "node",
      "args": ["generated/server.mjs"]
    }
  }
}

Supported clients: Claude Desktop, Cursor, VS Code / Copilot, and any client that speaks MCP over stdio.

Tech stack

Layer	Technologies
Frontend	React 18 · TypeScript · Vite · TailwindCSS · React Router · lucide-react
Backend	Node.js · TypeScript · Express · @modelcontextprotocol/sdk · Zod
Generator	Compiles project.json into a self-contained server.mjs (stdio)

Data storage

Everything lives in a single, Git-friendly file:

projects/example-project/project.json

Export it from the Dashboard to back it up or share it. Local secrets are kept in a separate secrets.json that is git-ignored by default.

Developer commands

npm run install:all   # install everything (root + backend + frontend)
npm run dev           # run backend + frontend together with live reload
npm run build         # type-check and build both

• Backend — backend/ (Node + TypeScript + Express + official MCP SDK).
• Frontend — frontend/ (React + TypeScript + Vite + TailwindCSS).
• Generator — turns project.json into a self-contained MCP server at generated/server.mjs.

The generated server links to the installed dependencies, so a connected client can launch it directly. To run it on another machine, run npm install inside generated/ first.

Roadmap

Shipped

• [x] No-code Tool Wizard (HTTP, integration, JavaScript / Python script)
• [x] One-click connect for Claude Desktop, Cursor, VS Code (Copilot)
• [x] Project import / export (project.json)
• [x] Connection presets with built-in auth (Jira, GitHub, Slack, Notion, REST)
• [x] Single-command launcher (backend + web app in one window)

Next — three pillars

1. Integration presets with ready-made tools Turn presets from connection-only into one-click packs that drop in working tools, so a new user gets value without building anything by hand.

• [ ] Bundle starter tools per service (e.g. Jira: search / create / comment on issues; GitHub: list / create issues, search repos)
• [ ] Add Google (Sheets, Calendar, Gmail) and broaden existing packs
• [ ] "Add pack" UX: pick a service, get its tools pre-wired to your credentials
• [ ] Friendly per-field guidance (where to get the token, scopes needed)

2. HTTP transport with auth (self-hosting) Run the generated server on a shared/corporate host instead of only locally over stdio.

• [ ] Streamable-HTTP / SSE transport option in the generator (alongside stdio)
• [ ] Auth on the HTTP endpoint (bearer / API key), configurable per server
• [ ] Remote-URL connect snippets for Claude, Cursor, VS Code
• [ ] Deploy notes (port, reverse proxy, secrets) for a corp server

3. Python scripting out of the box Make Python tools reliable on any machine — no "install Python first".

• [ ] Managed / detected Python runtime so scripts run with zero setup
• [ ] Per-tool dependencies (pip) resolved automatically
• [ ] Hardened execution wrapper (clean params in, structured result out)

Not planned: a public marketplace of community templates. The focus is curated, first-party presets that work out of the box.

Contributing

Contributions, bug reports, and feature requests are welcome.

1. Fork the repository and create your branch: git checkout -b feature/my-feature
2. Make your changes and run npm run build to type-check.
3. Commit, push, and open a pull request.

The codebase favors modular, well-typed, feature-based code and a plugin-style architecture, so new integrations require minimal changes elsewhere.
