geoaeo for GitHub Copilot

What you get

• CLI bins: geoaeo and geoaeo-mcp
• CLI commands: audit, init, gen, humanize, mcp. No other commands exist.
• MCP server command: npx geoaeo-mcp over stdio
• MCP tools: audit, gen, humanize

Prerequisites

• Node.js 20 or later
• VS Code with GitHub Copilot and Copilot Chat
• MCP support enabled in VS Code (Copilot agent mode)
• A site directory or URL to audit

Install geoaeo

# one-off
npx geoaeo audit ./ --json

# or add to the project
npm install -D geoaeo
npx geoaeo --help

# verify the MCP binary
npx geoaeo-mcp --help

VS Code starts geoaeo-mcp for you. You do not run it by hand.

Configure the MCP server

VS Code reads MCP servers from .vscode/mcp.json (workspace scope) or from your user settings. Use servers (VS Code format) or mcpServers where supported. Both shapes are shown.

Workspace scope (recommended)

Create .vscode/mcp.json in the repo root:

{
  "servers": {
    "geoaeo": {
      "command": "npx",
      "args": ["-y", "geoaeo-mcp"],
      "type": "stdio"
    }
  }
}

Some VS Code builds use mcpServers as the top-level key instead of servers. If the block above does not load, use this equivalent:

{
  "mcpServers": {
    "geoaeo": {
      "command": "npx",
      "args": ["-y", "geoaeo-mcp"]
    }
  }
}

Steps:

1. Create .vscode/mcp.json.
2. Paste one block above. Validate JSON.
3. Reload VS Code (Developer: Reload Window).
4. Open Copilot Chat, switch to Agent mode, and check the tools/MCP panel. Confirm geoaeo shows with audit, gen, humanize.

Global scope: add the same server entry to your VS Code settings.json under chat.mcp.servers or mcp.servers depending on your VS Code version.

Verify the connection

1. Open Copilot Chat in Agent mode.
2. Ask: "What MCP tools does geoaeo provide?"
3. Confirm audit, gen, and humanize appear under geoaeo.

If no tools appear, see Troubleshooting.

Walkthrough 1 — audit a site

Prompt Copilot:

Use geoaeo audit on ./ and summarize the score and the top 3 fixes. If ./ has no pages, try https://example.com.

What the agent does:

1. Calls audit with {"target": "./"} or {"target": "https://example.com"}.
2. Receives JSON: score, checks[], topFixes[].
3. Reports the score and next steps.

Equivalent CLI:

npx geoaeo audit ./ --json
npx geoaeo audit https://example.com --json

Use topFixes to choose the next artifact to generate.

Walkthrough 2 — generate an artifact with gen

This uses gen, which reads geoaeo.config.ts from the current directory.

1. Scaffold config if missing:

   npx geoaeo init ./
   cat geoaeo.config.ts

2. Prompt Copilot:

   Use geoaeo gen to create the WebMCP manifest for this site. Show the JSON and write it to public/webmcp.json.

What the agent does:

1. Calls gen with {"artifact": "webmcp"}.
2. Returns the JSON manifest.
3. Writes it to public/webmcp.json on confirmation.

Other artifacts:

• {"artifact": "llms"}
• {"artifact": "llms-full"}
• {"artifact": "sitemap"}
• {"artifact": "robots"}
• {"artifact": "jsonld", "type": "software"} — type may be software, product, faq, or breadcrumb

Equivalent CLI:

npx geoaeo gen webmcp
npx geoaeo gen webmcp -o ./public/webmcp.json
npx geoaeo gen llms -o ./public/llms.txt

The humanize tool is also available: {"glob": "content/**/*.md", "write": false}.

Troubleshooting

MCP server not shown in Copilot. Confirm the file is .vscode/mcp.json (not mcp.json at root). Validate JSON with cat .vscode/mcp.json | jq .. Ensure VS Code and Copilot Chat are up to date. Reload the window.

servers vs mcpServers confusion. VS Code has shipped both keys. If one key does not load, try the other. Keep type: "stdio" for the servers shape.

npx ENOENT or Node not found. Check node --version in VS Code's integrated terminal. On macOS, launch VS Code from a shell that has Node on PATH, or set an absolute command path such as "/opt/homebrew/bin/npx".

audit returns low score. Audit the workspace root. Ensure Copilot's cwd is the repo root so {"target": "./"} resolves there.

gen fails with Cannot find config. Run npx geoaeo init ./ in the workspace root, then retry gen.

Reference

• Package: geoaeo. Bins: geoaeo, geoaeo-mcp.
• Transport: stdio only.
• Tools: audit takes target (string). gen takes artifact enum and optional type. humanize takes glob and optional write (boolean).
