Use this page when you want a Claude Code-specific manual setup.
Need setup for Codex, Gemini, Cursor, VS Code, or Windsurf? Use the canonical multi-client guide: MCP Setup.
If you install the Char plugin, setup is one command flow and all servers are added automatically. 
/plugin marketplace add WebMCP-org/char-plugin
/plugin install char@webmcp
/char:setup
This auto-configures chrome-devtools, char-docs, webmcp-docs, and char-saas.

​
Install all servers

claude mcp add --transport http char-docs https://docs.usechar.ai/mcp
claude mcp add --transport http webmcp-docs https://docs.mcp-b.ai/mcp
claude mcp add --transport http char-saas https://app.usechar.ai/mcp
claude mcp add chrome-devtools npx -y @mcp-b/chrome-devtools-mcp@latest
Chrome DevTools MCP uses our maintained fork package: @mcp-b/chrome-devtools-mcp. Source: WebMCP-org/npm-packages/packages/chrome-devtools-mcp.

​
Verify installation

/mcp
Confirm you see all four servers listed.

​
First-time authentication (char-saas)

The first time you use a Char SaaS tool, a browser window opens:
  1. Sign in — Use your identity provider or create a new account
  2. Name your organization — Char suggests a name based on your email domain
  3. Authorize — Click “Authorize” and return to Claude Code
This only happens once. Claude Code remembers your session.

​
Troubleshooting (Manual Setup)

​
MCP not appearing

Restart Claude Code and run /mcp again.

​
Permission errors

Install Chrome DevTools MCP globally: 
npm install -g @mcp-b/chrome-devtools-mcp
claude mcp add chrome-devtools chrome-devtools-mcp

​
OAuth flow not completing

  1. Check that you completed the sign-in flow
  2. Verify the browser didn’t block the redirect
  3. Restart Claude Code and try the tool again
