What is MCP?
MCP, the Model Context Protocol, is an open standard that lets an AI agent connect to an outside service and use its tools, a bit like a universal plug between AI apps and the services they work with.
Also called: Model Context Protocol.
In plain words
Before MCP, every AI app needed its own custom connection to every service. If you wanted Claude to read your calendar and ChatGPT to read the same calendar, someone had to build two separate integrations.
MCP fixes that with one shared way of describing tools. A service publishes its tools once, on an MCP server, and any AI app that speaks MCP can use them. The AI app is called the client. It asks the server which tools exist, reads a short description of each, and calls them when it needs to.
For a business owner, the useful part is choice. You can pick the AI agent you like, and later switch to another, without losing the services it is connected to. Adding a service is usually a matter of pasting a web address and a key into your AI app's settings.
MCP does not decide what an agent is allowed to do. That is up to the service behind the server, which can refuse requests, apply limits and ask for a key or a sign-in.
How it works in Spaces
Spaces runs an MCP server at https://api.spacesos.com/mcp, so any agent that supports MCP can read and reply on the accounts you connect. There is also a server for each channel, such as one for WhatsApp only.
Spaces applies its pacing and daily limits on its own side, so they hold whichever AI agent you use. If you change agents, your connected accounts and their limits stay as they were.
Related terms
- MCP server: An MCP server is the web address a service publishes so AI agents can find and use its tools through the Model Context Protocol.
- AI agent: An AI agent is an AI model, such as ChatGPT, Claude or Grok, that can take actions with tools you give it, like reading a message and sending a reply, rather than only chatting.
- API: An API, or application programming interface, is a set of rules that lets one piece of software ask another to do something, such as send a message or list your conversations.
- API key: An API key is a long secret code that proves to a service that a request comes from you, so it works like a password for software rather than for people.
FAQ
What does MCP stand for?
Model Context Protocol. It is an open standard for connecting AI agents to outside tools and services.
Do I need to be technical to use MCP?
Not usually. In most AI apps you add an MCP server by pasting its address and a key into the settings. Spaces gives you both when you sign up.
Is MCP the same as an API?
They are related. An API is how software talks to a service. MCP is a standard way for AI agents in particular to find and use a service's tools.
Which AI apps support MCP?
The agents Spaces lists, including Claude Code, Claude, Cursor, Codex, ChatGPT, Grok, OpenClaw and Hermes, all connect through MCP.
Does MCP make an agent safe on its own?
No. Safety comes from the service behind the server. Spaces enforces sending limits and refusals there, whatever the agent asks for.
