+# MCP Config Examples
+
+Sample MCP (Model Context Protocol) configurations across Claude Desktop, Cursor, Cline, Windsurf, and Zed — both VALID examples to copy-paste and INVALID ones for fixture-driven testing of MCP linters.
+
+```python
+from datasets import load_dataset
+ds = load_dataset("mukunda1729/mcp-config-examples", split="train")
+print([r["scenario"] for r in ds if not r["valid"]])
+```
+
+## Schema
+
+| Field | Type | Notes |
+|---|---|---|
+| `client` | `str` | `claude-desktop`, `cursor`, `cline`, `windsurf`, `zed` |
+| `scenario` | `str` | Short label describing this fixture |
+| `config` | `object` | The actual MCP config JSON |
+| `valid` | `bool` | Whether the config is well-formed and safe |
+| `issues` | `array<str>` | Lint findings when `valid: false` |
+
+## Use cases
+
+- Fixture-driven tests for MCP config linters: [`mcpcheck-py`](https://pypi.org/project/mcpcheck-py/), [`mcp-config-check`](https://pypi.org/project/mcp-config-check/), [`@mukundakatta/mcpcheck`](https://www.npmjs.com/package/@mukundakatta/mcpcheck).
+- Copy-paste templates when configuring an MCP client for the first time.
+- Negative-test corpus for tools that need to detect dangerous configs.
