Diagnose runtime errors by connecting to dev server via MCP.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Debug Runtime

Diagnose runtime errors by connecting to the dev server via MCP.

## Steps

1. **Ensure dev server is running**
   ```bash
   veryfront dev
   ```
   MCP is available on the dev server port plus 2. The default URL is
   `http://localhost:3002/mcp`.

2. **Check for errors** (via MCP)
   Use `vf_get_errors` to get current runtime errors.

3. **Get debug context** (via MCP)
   Use `vf_get_debug_context` for stack traces and request context.

4. **Read server logs** (via MCP resource)
   Read `veryfront://logs` for recent server log entries.

5. **Trace the issue**
   - Identify the failing route or component from error context
   - Read the source file
   - Check for common runtime issues: missing env vars, API failures, data fetch errors

6. **Fix and verify**
   Apply the fix. HMR will auto-reload.
   Use `vf_get_errors` to confirm the error is resolved.

## Error Recovery

- **Dev server not running**: Start with `veryfront dev`
- **MCP not responding**: Check the printed MCP URL, restart dev server
- **Error persists after fix**: Clear cache with `veryfront clean`, restart dev

How to install

The exact contents, by fingerprint

mdr add veryfront/veryfront-code/debug-runtime@sha256:f441369dbcf75c50

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
