@inariwatch/capture-mcp

Local MCP dev-mode server for @inariwatch/capture. Exposes the most recent errors captured by your app over JSON-RPC 2.0 / stdio so editors (Cursor, Claude Code, Continue, …) can read them directly while you're debugging — no cloud round-trip needed.

How it works

1. Your app runs @inariwatch/capture with INARIWATCH_DEV_LOG=1 (or sets INARIWATCH_DEV_LOG_PATH=…). Every captured event is appended to ${cwd}/.inariwatch/errors.jsonl.
2. Your editor's MCP client spawns npx @inariwatch/capture-mcp. The server reads the JSONL tail and serves it via three tools.
3. The editor's LLM calls those tools while you ask "what errors am I hitting right now?"

Tools exposed

| Tool | Purpose | |---|---| | get_recent_errors | Last N errors, filterable by severity | | diagnose_error_id | Full event by fingerprint (stack, locals, hypotheses, …) | | get_locals_at_frame | Forensic locals + async stack at a specific frame |

Editor setup

Cursor / Claude Code / Continue

Add to your MCP config (e.g. ~/.cursor/mcp.json):

{
  "mcpServers": {
    "inariwatch-capture": {
      "command": "npx",
      "args": ["-y", "@inariwatch/capture-mcp"],
      "env": {
        "INARIWATCH_DEV_LOG_PATH": "/absolute/path/to/your-project/.inariwatch/errors.jsonl"
      }
    }
  }
}

INARIWATCH_DEV_LOG_PATH is optional; defaults to ${cwd}/.inariwatch/errors.jsonl.

Status

v0.1.0-alpha.0 — dev-mode only, single-file JSONL store. The cloud-side production tools live in the hosted MCP server at mcp.inariwatch.com (not this package).
