Hosted MCP server, 11 tools

Give OpenAI Codex CLI eyes on the web

Connect the hosted SnapRender MCP server to OpenAI Codex CLI with codex mcp add. Codex detects OAuth, opens the sign-in, and can then screenshot and read any web page.

200 renders a month free, no card. Sign-in happens inside OpenAI Codex CLI the first time it uses the server.

Server URL: https://app.snap-render.com/mcp

Set it up (recommended: sign in with OAuth)

Codex supports remote HTTP servers. When you add one, it checks for OAuth and starts the browser sign-in.

  1. 1Run the command below, or add the TOML block to ~/.codex/config.toml.
  2. 2Sign in to SnapRender in the browser window Codex opens. If it does not open, run codex mcp login snaprender.
  3. 3Ask Codex for a screenshot.
Terminal
codex mcp add snaprender --url https://app.snap-render.com/mcp
~/.codex/config.toml
[mcp_servers.snaprender]
url = "https://app.snap-render.com/mcp"

Check it worked: codex mcp list shows the server; in the Codex interface, /mcp lists it with its tools.

With an API key instead

Codex reads the key from an environment variable you name, so it never sits in the config file: Get a key from your SnapRender dashboard.

Terminal
export SNAPRENDER_API_KEY=YOUR_API_KEY
codex mcp add snaprender --url https://app.snap-render.com/mcp --bearer-token-env-var SNAPRENDER_API_KEY
~/.codex/config.toml
[mcp_servers.snaprender]
url = "https://app.snap-render.com/mcp"
bearer_token_env_var = "SNAPRENDER_API_KEY"

Or run the server locally

Runs the open-source server from npm locally. Replace YOUR_API_KEY with the key from your SnapRender dashboard. The package is snaprender-mcp on npm.

Terminal
codex mcp add snaprender --env SNAPRENDER_API_KEY=YOUR_API_KEY -- npx -y snaprender-mcp

Questions

Does Codex CLI support OAuth MCP servers?+

Yes. codex mcp login runs the browser sign-in, and adding a server with --url starts it automatically when the server supports OAuth.
