# Agent Clients

Blekline connects to **Layer 5** agent clients via `@blekline/mcp-server` and `@blekline/mcp-proxy`.

## Compatibility matrix

## Universal MCP env

```bash
export BLEKLINE_WORKSPACE_TOKEN="blw_..."
export BLEKLINE_API_URL="https://app.blekline.com"
export BLEKLINE_CLIENT_SURFACE=cursor  # or continue, github-copilot, openhands, sourcegraph-cody
```

## When to pick which

- **Cursor** — default for coding agents (P0).
- **Continue** — open-source IDE, VS Code / JetBrains.
- **GitHub Copilot** — VS Code enterprise standard.
- **OpenHands** — autonomous sandbox agents.
