description: "Engineering context and operational memory for your stack — connect once, investigate anywhere."
---
[Combie](https://github.com/BoringInfraCo/combie) is an open engineering context layer. It connects your providers once, builds evidence-backed relationships between resources, and makes that context available via CLI and read-only MCP for humans and coding agents.

**Core loop:** Connect → Sync → Understand → Investigate

## What it does

- Connect GitHub, Vercel, Cloudflare, Sentry, Neon, and PlanetScale
- Build deterministic relationships between resources (no guessing)
- Investigate resources with task-scoped profiles
- Record operational memory: investigations, resolutions, incidents
- Expose read-only context to Cursor, Claude Code, and Codex via MCP

## Supported providers

| Provider | Resources discovered |
|----------|---------------------|
| GitHub | Repositories |
| Vercel | Projects, deployments |
| Cloudflare | Workers, D1, KV, zones |
| Sentry | Projects, releases, issues |
| Neon | Databases |
| PlanetScale | Databases |

## Proven relationships

Combie only records relationships it can prove with evidence:

| Edge | Example |
|------|---------|
| `source_for` | GitHub repo → Vercel project |
| `uses_domain_in` | Vercel project → Cloudflare zone |
| `code_mapped_to` | GitHub repo → Sentry project |
