How to add an MCP server

MCP (Model Context Protocol) is the standard way to plug an outside capability into your AI tool. One address, and your ChatGPT, Claude or Codex can use a system someone else runs: live data, real skills, real actions. This page has the exact steps for every major tool.

What MCP is, in three sentences

MCP is an open standard that lets an AI tool call another system's abilities, called tools, over one https address. The AI reads what the server offers, decides when to use it, and shows you the result in the same chat you already use. Think of it as a power socket: any MCP server plugs into any MCP-capable AI.

An MCP address looks like this: https://example-server.com/mcp. That is all you need for every method below.

First, get an address

Every MCP server publishes its own address. If you are here for the two connectors on this site (Raza SOR, the record that counts your workflow with you, and raza-Developer, the spec-driven builder), their addresses arrive by email after a quick check: get the addresses here. The email also contains the exact ready-made command for your tool.

ChatGPT (web and desktop)

  1. In the left sidebar, click Plugins.
  2. Click the + button, top right beside the plugin search box.
  3. In the New Plugin form, give it a name, keep Connection on Server URL, and paste the MCP address.
  4. Set Authentication to No auth. That is correct for free connectors, including the two on this site; paid servers use OAuth instead.
  5. Tick I understand and want to continue, then press Create.
  6. In a new chat, ask your question; ChatGPT calls the plugin when it needs it.

Claude (claude.ai)

  1. Open Settings, then Connectors.
  2. Choose Add custom connector.
  3. Paste the MCP address, name it, and confirm.
  4. Start a chat; Claude lists the connector's tools and uses them when your question needs them.

Claude Code (terminal)

One command, with your own name and address filled in:

claude mcp add --transport http your-name https://the-address/mcp

Run it once from any folder. Every later session can use the connector; remove it any time with claude mcp remove your-name.

Codex (terminal)

codex mcp add your-name --url https://the-address/mcp

Same idea: one command, then the connector is available in every Codex session.

VS Code

  1. Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P).
  2. Run MCP: Add Server.
  3. Choose HTTP, paste the address, and name it.
  4. The server appears in your MCP list; agent mode can now call its tools.

Check it worked

  1. Look for the tools. Your AI tool lists the connector and the tools it offers (a search, a read, an action).
  2. Ask a question the server should answer. For example, ask Raza SOR: "how much of my workflow can be automated?" and it builds your step table with you.
  3. Expect one slow first reply. Servers sleep when unused; the first response can take 20 to 30 seconds, then it is fast.

FAQ

Is it safe to add an MCP server?+

Treat an MCP address like an app install: add servers only from people or companies you trust. A read-only connector can only answer questions from its own data. A connector with write tools can act, so your AI tool asks you before it runs those actions.

Which AI tools support MCP?+

ChatGPT (web and desktop), Claude on claude.ai, Claude Code, Codex, and VS Code all support MCP connectors over HTTP. Most other coding agents support it too, with a similar add command.

Where do I get an MCP address?+

Every MCP server has an https address ending in /mcp, published by whoever runs it. The two connectors on this site, Raza SOR and raza-Developer, hand out their addresses after a quick email check on the access page.

Does adding a connector cost anything?+

Adding a connector is free and takes about a minute. You pay only for your own AI tool subscription, as before. The connectors on this site are free to attach.

What is the difference between an MCP connector and a GPT or extension?+

A GPT or extension lives inside one product. An MCP server is one address that works across ChatGPT, Claude, Codex, VS Code and other tools at the same time, and it can carry live data and real actions rather than a frozen prompt.

What to attach first

Start with the record: attach Raza SOR and ask it to count your own workflow; it can send me the sketch when you are done. Builders should read the raza-Developer guide next. Both addresses are one email away: Get the MCP addresses
