# Client QA matrix

MCP is **client-agnostic** — once Blekline MCP is connected, verify tools per surface.

## Repo checklist

See [`demo/qa/client-matrix.md`](https://github.com/Blekline/blekline-oss/blob/main/demo/qa/client-matrix.md) on blekline-oss.

## Minimum smoke (4 checks)

| Surface | Tool | Pass |
|---------|------|------|
| Cursor | `blekline_mask_prompt` | [ ] |
| Claude Code | `blekline_evaluate_tool_call` | [ ] |
| Claude Desktop | `blekline_mask_prompt` | [ ] |
| Codex | `blekline_mask_prompt` | [ ] |

## Proxy check

Any surface + `blekline-proxy` — block or mask a secret in tool arguments.

## Metadata verification

Events should include `clientSurface` matching `BLEKLINE_CLIENT_SURFACE`. See [Telemetry spec](/docs/reference/telemetry-spec).
