Install & config
- Copy the command above
- Paste it as one entry under
mcpServersinclaude_desktop_config.json— local servers take command + args (example: clients) - Restart your client
Client config (built from the install command this repo gives)
{
"mcpServers": {
"arif-js-agentsensor": {
"command": "npx",
"args": ["-y", "agentsensor-mcp"]
}
}
}Parsed from the README we fetched on 2026-10-26; we have not executed it.
command/args come from the install command the repository states. When it is ambiguous, the project README wins.
VS Code (.vscode/mcp.json - the key is servers)
{
"servers": {
"arif-js-agentsensor": {
"command": "npx",
"args": ["-y", "agentsensor-mcp"]
}
}
}Same server, but VS Code keeps it under <code>servers</code>.
Claude Code (command line)
claude mcp add --transport stdio arif-js-agentsensor -- npx -y agentsensor-mcp
Claude Code does not read a config file; add the server with this command.

FAQ (answers come from our records)
How do I install it?
The repository provides this install command:
npx -y agentsensor-mcp. It comes from the repository itself; we cannot guarantee it runs as-is in your client.Who is it for?
We filed it under these tags: MCP 服务. The tags come from the entry itself, not a taxonomy we imposed.

Zero-config runtime & browser error sensor for AI coding agents.
Wrap your dev server with one command, then let Claude Code, Codex, Cursor, Antigravity, or any MCP client see the real crashes from your terminal and browser — mapped to the exact file and line, with zero copy-paste.

> Status: pre-release (0.1). Expect rapid improvements before 1.0.
## What it does
⚡ Zero code changes: wrap your existing dev script (agentsensor run -- npm run dev). No SDK imports, no middleware, no config files.
🌐 Captures both server and browser crashes: intercepts backend runtime exceptions, bundler compilation errors, and in-browser exceptions (window.onerror, unhandledrejection, React component errors).
🎯 Source-mapped to your real code: automatically enables --enable-source-maps, strips monorepo runner prefixes, collapses nodemodules noise, and maps browser URLs back to exact workspace files.
📋 Live open vs resolved status board: maintains .agentsensor/status.json so fixed errors from earlier sessions never confuse the agent — while automatically reopening an error if it ever happens again.
🤖 Automatic agent triggering: sends MCP server instructions so connected agents check getruntimeerrors first whenever you report a bug or crash.
🔒 100% local: no accounts, no cloud, no telemetry, no background daemons.
AgentSensor doesn't guess fixes — it gives your coding agent the exact runtime reality (error type, message, source-mapped file:line:column, and the 30 log lines leading up to the crash) so the agent fixes the real bug on the first try.
## Supported stack
AgentSensor currently supports the Node.js, JavaScript, and TypeScript ecosystem:
| Layer | Supported | Details |
| Runtimes | Node.js (>=18.17) | JavaScript & TypeScript |
| Frontend & SSR | Next.js, Vite, Remix, Storybook | Dev server builds & browser crashes (window.onerror, unhandledrejection, React console.error) |
| Backend | Express, Fastify, NestJS, Koa, Node CLI scripts | V8 exceptions, unhandled promise rejections, source-mapped stack traces |
| Compilers & Bundlers | tsc, Turbopack, Webpack, esbuild, Babel | Build-time errors, type errors, syntax crashes |
| Monorepos | pnpm, Turborepo, Nx | Strips runner prefixes, maps local package paths |
> [!NOTE]
> Non-Node runtimes (Python, Go, Rust): Not supported yet. Dedicated runtime hooks and stack trace parsers for these languages are planned for upcoming releases.
## Demo
Run your dev server through agentsensor:
sh
npx -y agentsensor-mcp run -- npm run dev
When your app or browser throws an error, just talk to your assistant naturally:
> You: The checkout page just crashed — fix it.
> Claude: (calls getruntimeerrors → geterrordetail)
> Found OPEN error [9e84385bb1]: TypeError: Cannot read properties of undefined (reading 'code') at src/checkout/total.ts:17:38.
> I added a guard for optional coupon in calculateTotalCents and called checkfix — error [9e84385bb1] is now marked resolved in .agentsensor/status.json.
## Who it's for
Developers using AI coding agents: stop acting as the manual copy-paste bridge between terminal errors, Chrome DevTools, and chat windows (Claude Code, Codex, Antigravity, Cursor, Windsurf, Copilot).
