### Description (declared)

## tcpping MCP Server (stdio) 
 
Minimal TCP latency probe server for MCP clients (e.g. GitHub Copilot Agents) using Playwright + FastMCP. 
 
> 0.1.4: Added resilient fallback parsing (summary pattern search + heuristic row scan) and debug artifacts when structure changes on pingloc.com. 
 
### 1. Add to your MCP client config 
Example (`mcp.json` / Copilot Agents user settings): 
```jsonc 
"tcpping-mcp-server": { 
 "type": "stdio", 
 "command": "uvx", 
 "args": [ 
 "tcpping-mcp-server" 
 ] 
} 
``` 
`uvx` will fetch & run the published script (or local cache) by name. You can also swap for `python -m tcpping_mcp_stdio.modern_server` if installed in a venv. 
 
### 2. Available tool 
Tool name: `tcpping_run` 
 
Parameters (all optional unless noted): 
- target (str, required) – domain or URL (scheme optional) 
- port (int, default 443) 
- timeout (float, default 120) 
- retries (int, default 1) 
- headless (bool, default true) 
- browser_channel (str, default "msedge") 
- debug (bool, default false) – dump HTML/screenshot if no rows 
- summary_only (bool, default false) – return compact summary 
 
### 3. Example call (conceptual JSON-RPC) 
```json 
{ 
 "jsonrpc": "2.0", 
 "id": "1", 
 "method": "tools/call", 
 "params": { 
 "name": "tcpping_run", 
 "arguments": { "target": "example.com", "summary_only": true } 
 } 
} 
``` 
 
### 4. Local install (optional) 
```bash 
pip install tcpping-mcp-server 
tcpping-mcp-server  # or: python -m tcpping_mcp_stdio.modern_server 
``` 
 
### 5. Playwright browser dependency 
First run will auto-download browsers when using `uvx` or after pip install. If needed manually: 
```bash 
playwright install chromium 
``` 
 
### 6. Output 
Returns a JSON string (you may need to parse once): 
``` 
{ 
 "host": "example.com:443", 
 "summary": { ... }, 
 "probes": [ ... ], 
 "probe_count": 25, 
 "timeouts": 0, 
 "duration_sec": 12.34 
} 
``` 
 
### 7. Debugging 
Set `debug=true` to dump HTML + screenshot into `tcpping/debug/` when no probe rows c…
