# Validation Doctor
## Diagnostics
1. **Chrome DevTools MCP**
- Probe by calling `list_pages` (may appear as `mcp6_list_pages` depending on the client).
2. **Brave Search MCP**
- Probe by calling `brave_web_search` with a trivial query and `count=1`.
## Status Report
| Component | Status | Action Required |
|-----------|--------|-----------------|
| Market Validator (Brave) | ✅ / ❌ | [Config Snippet / None] |
| Technical Validator (Chrome) | ✅ / ❌ | [Config Snippet / None] |
## Setup Snippets
+ Never just say "install them" — output the exact JSON to paste.
+
### Chrome DevTools (NPX)
+
+ Requirements: Node.js v20.19+ and current stable Chrome.
```json
{
"mcpServers": {
"chrome-devtools": {
"command": "npx",
"args": ["-y", "chrome-devtools-mcp@latest"]
}
}
}
```
### Brave Search (NPX)
```json
{
"mcpServers": {
"brave-search": {
"command": "npx",
"args": ["-y", "@brave/brave-search-mcp-server", "--transport", "stdio"],
"env": {
"BRAVE_API_KEY": "YOUR_API_KEY_HERE"
}
}
}
}
```
## Runtime Policy
- If `chrome-devtools` is unavailable, allow `fetch` fallback but mark results as **Low Confidence**.
- If `brave-search` is unavailable, do not claim competitor positioning; only score the page itself.
