Connect your AI app

One URL connects Speed to every AI app: https://app.tryspeed.ai/mcp. Add it, click Connect, and click Allow.

View as Markdown

Speed's connector is a hosted MCP server. Every AI app uses the same URL:

Connector URL
https://app.tryspeed.ai/mcp

You never need an API key, a client ID, a client secret, a plugin or Node. If an app asks for any of those, leave the field blank.

What happens when you connect#

  1. You add the URL to your AI app and click Connect (or the app's sign-in button).
  2. A Connect Speed page opens on app.tryspeed.ai. Sign in if it asks: Continue with Apple, a work email link, or an access code.
  3. Click Allow. Your AI app now has Speed's tools.
  4. When the chat first uses Speed, it sends you a link to your Speed tab, https://app.tryspeed.ai/?agent=connect. Open it in any browser: the link carries the connection, so the tab connects by itself.

Technical detail, for IT teams: remote MCP over Streamable HTTP, with OAuth 2.1, dynamic client registration and PKCE.

Which apps are tested#

Tested means we have run a full build through that app end to end (claude.ai, 6 November 2026). Not tested yet means the steps follow the app maker's current docs, but we have not run a build through it yet.

Claude (claude.ai and Claude Desktop)#

TestedAdd Speed once as a custom connector. Tested end to end on claude.ai on 6 November 2026. Claude Desktop uses the same connector.

  1. Open claude.ai (or the Claude Desktop app) and go to Customize → Connectors. Older versions have it under Settings → Connectors.
  2. Click + Add, then Add custom connector.
  3. Type the name Speed and the URL https://app.tryspeed.ai/mcp. Click Continue.
  4. Claude detects the sign-in settings by itself: Sign in now, and OAuth client Register automatically. Leave them as detected and click Add. Do not enter an API key, a client ID, a secret or a header.
  5. Click Connect. A Connect Speed page opens on app.tryspeed.ai. Sign in if it asks, then click Allow. Claude shows Connected to Speed.
  6. Under Tool permissions, every tool starts as Needs approval. For a smooth run, set both groups, Read-only tools and Write/delete tools, to Always allow. Otherwise Claude stops to ask before every step.
  7. In a chat, click + (bottom left of the message box) → Connectors and check Speed is switched on.
Connector URL
https://app.tryspeed.ai/mcp
  • Team and Enterprise plans: only an Owner can add a custom connector. The Owner goes to Organization settings → Connectors → Add, hovers Custom, picks Web, and enters the same name and URL. Each member then finds Speed in Customize → Connectors and clicks Connect.
  • The Free plan allows one custom connector.
  • Claude Desktop uses the connectors on your Claude account. You do not edit any config file.

Claude Code#

Not tested yetOne command adds Speed. Then you sign in once from inside Claude Code.

  1. Open a terminal and run the command below. It adds Speed to Claude Code for the folder you are in.
  2. Start Claude Code in that folder: type claude and press Enter.
  3. Type /mcp and press Enter. Choose speed, then Authenticate.
  4. Your browser opens a Connect Speed page. Sign in if it asks, then click Allow. Claude Code now lists speed as connected.
Terminal
claude mcp add --transport http speed https://app.tryspeed.ai/mcp
  • To use Speed from every folder, add --scope user: claude mcp add --transport http --scope user speed https://app.tryspeed.ai/mcp.
  • If Claude Code was already running when you added Speed, quit it (type /exit) and start it again so it sees the new server.

ChatGPT#

Not tested yetChatGPT adds remote MCP servers as plugins. Your workspace policy decides whether you can add one.

  1. Go to chatgpt.com/plugins.
  2. Click +, then Add custom MCP server.
  3. Name: Speed. Under Connection, enter the server URL https://app.tryspeed.ai/mcp. Set authentication to OAuth.
  4. Read the risk warning, confirm it, and click Create as a plugin. Install the plugin.
  5. When ChatGPT asks you to sign in, a Connect Speed page opens. Sign in if it asks, then click Allow.
  6. Start a new chat, type @ and pick Speed.
Server URL
https://app.tryspeed.ai/mcp
  • On Business, Enterprise and Edu workspaces, an admin may have to allow custom MCP servers first.
  • Older guides describe this as Settings → Apps → Advanced settings → Developer mode → Create app. Use that path if your account still shows it.

Codex CLI#

Not tested yetAdd Speed with one command, then log in with a second.

  1. In a terminal, run the two commands below. The second one opens your browser.
  2. On the Connect Speed page, sign in if it asks, then click Allow.
  3. Start Codex (codex) and paste the Speed prompt.
Terminal
codex mcp add speed --url https://app.tryspeed.ai/mcp
codex mcp login speed
Or add it to ~/.codex/config.toml
[mcp_servers.speed]
url = "https://app.tryspeed.ai/mcp"
  • codex mcp add does not log in by itself. Run codex mcp login speed after it, and again if the login expires.

Cursor#

Not tested yetAdd Speed to Cursor's MCP config file, then sign in from Cursor's MCP settings.

  1. Open (or create) ~/.cursor/mcp.json for every project, or .cursor/mcp.json in one project.
  2. Paste the config below. If the file already has an mcpServers block, add only the speed entry inside it.
  3. Save the file. In Cursor's MCP settings, Speed shows a sign-in prompt: click it.
  4. On the Connect Speed page, sign in if it asks, then click Allow.
~/.cursor/mcp.json
{
  "mcpServers": {
    "speed": {
      "url": "https://app.tryspeed.ai/mcp"
    }
  }
}
  • Team admins can restrict Cursor to an allowlist of MCP servers. If Speed does not appear, ask them to allow the URL.

VS Code (GitHub Copilot)#

Not tested yetAdd Speed as an HTTP server for Copilot's agent mode.

  1. Open the Command Palette and run MCP: Add Server. Choose HTTP, paste the URL below and name it speed. Or paste the config below into .vscode/mcp.json in your project.
  2. Start the server (VS Code shows a Start link above it in mcp.json). Your browser opens a Connect Speed page: sign in if it asks, then click Allow.
  3. Open Copilot Chat in Agent mode and paste the Speed prompt.
.vscode/mcp.json
{
  "servers": {
    "speed": {
      "type": "http",
      "url": "https://app.tryspeed.ai/mcp"
    }
  }
}
  • Your organisation's Copilot policy can turn MCP servers off. If the Add Server command is missing, ask your admin.

Gemini CLI#

Not tested yetAdd Speed with one command, then authenticate from inside Gemini CLI.

  1. In a terminal, run the command below.
  2. Start Gemini CLI (gemini), type /mcp auth speed and press Enter.
  3. On the Connect Speed page, sign in if it asks, then click Allow.
Terminal
gemini mcp add --transport http speed https://app.tryspeed.ai/mcp
Or add it to ~/.gemini/settings.json
{
  "mcpServers": {
    "speed": {
      "httpUrl": "https://app.tryspeed.ai/mcp"
    }
  }
}
  • Use httpUrl, not url. In Gemini CLI, url means an SSE server.
  • Google replaced Gemini CLI with Antigravity CLI for unpaid and Google One users on 18 June 2026. Antigravity CLI reads ~/.gemini/config/mcp_config.json and uses serverUrl for the URL.

Windsurf (Devin Desktop)#

Not tested yetWindsurf is now Devin Desktop. Add Speed to Cascade's MCP config.

  1. In Cascade, open the MCP menu and choose to open the raw MCP config file (mcp_config.json). Open it from the menu rather than typing a path, because the location changed when Windsurf became Devin Desktop.
  2. Paste the config below. If the file already has an mcpServers block, add only the speed entry inside it.
  3. Save and refresh the MCP servers. If Speed shows Authenticate, click it, then sign in and click Allow on the Connect Speed page.
mcp_config.json
{
  "mcpServers": {
    "speed": {
      "serverUrl": "https://app.tryspeed.ai/mcp"
    }
  }
}
  • On Teams and Enterprise, admins can turn MCP off or allow only listed servers.

Check that it worked#

In a new chat with Speed switched on, send this:

Type this
Call Speed's status tool and tell me what it says.

If the chat says no Speed tab is connected and gives you a link, the connector works: open the link, sign in, and ask again. If the chat says it has no Speed tools, see Troubleshooting.

Then paste the Speed prompt to start designing.
