MCP in one sentence
MCP is a common plug that lets any AI assistant work with any app. That's all it is. The app describes its tools in a standard way, and the AI calls them.
Before MCP, every AI company built its own integrations, one app at a time. Now an app builds one MCP server and works with every assistant that speaks MCP. Anthropic introduced the protocol in late 2024, and OpenAI, Google and many developer tools added support during 2025.
How does MCP work?
There are three parts:
| Part | What it is | Example |
|---|---|---|
| Host | The AI app you chat in | Claude, ChatGPT, Gemini, Cursor |
| Server | The app's MCP endpoint | Takejam at https://api.takejam.com/mcp |
| Tools | The actions the server offers | "read the timeline", "edit the project", "look at frames" |
When you ask for something, the AI reads the list of tools, picks the right one, and fills in the details. The app does the work and reports back, and the AI keeps going until the job is done. You see each step in the chat, and in an app like Takejam you also watch the change happen live.
What does connecting an app look like?
For most people it's three clicks:
- Paste the app's MCP address into your AI app's connector settings.
- A sign-in page from the app opens. Sign in and choose what the AI may access.
- Click Allow.
That sign-in step uses OAuth, the same standard behind "Sign in with Google". The AI never sees your password. It gets a key it can use until you remove it.
Real example: editing video through MCP
Takejam's MCP server gives an AI eight tools: list projects, read a project, edit it, look up the editor's options, render frames to look at, read review notes, reply to notes, and undo its last edit. So when you ask Claude to "cut this to 30 seconds and add a bold title", it:
- reads your timeline,
- makes the edit as one undoable change,
- renders a few frames to check the result, and
- tells you what it changed.
Your team sees it happen live, and anything it did can be adjusted by hand. That's the difference between an AI that talks about your video and one that works in your editor.
Is MCP safe?
MCP is as safe as the server you connect and the access you grant. Good habits:
- Connect only apps you trust, ideally from the company's own website.
- Read what you're allowing. Takejam's page, for example, lists exactly what the AI can and can't do: it can edit projects in the chosen workspace, and it can't see files on your computer, your password or your billing.
- Remove access you don't use. Every connected AI should be removable from the app's settings. In Takejam that's Workspace settings → AI connector keys.
- Keep a human in charge. Prefer apps that show the AI's work and make it easy to undo.
Which AI apps support MCP?
| AI app | How to add an MCP server |
|---|---|
| Claude (web and desktop) | Customize → Connectors → Add custom connector. The Free plan allows one. |
| Claude Code | claude mcp add --transport http <name> <address> |
| ChatGPT | Developer mode, then create a connector (depends on plan) |
| Gemini | Custom apps in the Gemini web app (rolling out) |
| Cursor, VS Code and others | Add a remote MCP server in settings |
Menus change often, so check each app's help pages if something looks different.
Questions, answered
What does MCP stand for?
Model Context Protocol. It's an open standard for connecting AI assistants to apps, data and tools.
Is MCP only for developers?
No. Developers build MCP servers, but using one is usually a copy-paste and a sign-in. Claude, ChatGPT and Gemini all let regular users add them.
Is MCP the same as a plugin?
It's similar in spirit, but it's an open standard. One MCP server works with many AI apps instead of being built for a single one.
Can an MCP app see everything on my computer?
No. A remote MCP server only sees what its own app has, and only what you allowed when you connected it. Takejam, for example, never sees the media files on your computer.
How do I disconnect an MCP app?
Remove it in your AI app's connector settings and, if the app offers it, revoke its key on the app's side too.
