### Description (declared)

# stubborn-mcp

**MCP server for [Stubborn](https://github.com/stubborn-ai/stubborn)** — exposes source-neutral code and contract graph tools to Cursor and other MCP clients.

[![PyPI](https://img.shields.io/pypi/v/stubborn-mcp)](https://pypi.org/project/stubborn-mcp/)

Thin adapter over [`stubborn.api`](https://github.com/stubborn-ai/stubborn/blob/main/src/stubborn/api.py). All compile and contract graph logic lives in **[`stubborn-stub`](https://pypi.org/project/stubborn-stub/)**.

Part of the [stubborn-ai](https://github.com/stubborn-ai) program — see [stubborn-hub](https://github.com/stubborn-ai/stubborn-hub).

## Install

```bash
pip install stubborn-stub stubborn-mcp
stubborn try   # bundled fixture smoke test (no Java)
```

For binary/NDJSON SCIP indexing, install Stubborn with its SCIP extra:

```bash
pip install "stubborn-stub[scip]" stubborn-mcp
stubborn index --scip index.scip --out metadata/symbols.db
export STUBBORN_DB=metadata/symbols.db
stubborn-mcp
```

Contract-only databases are also supported:

```bash
stubborn index-openapi \
  --openapi openapi.json \
  --service customers-service \
  --workspace petclinic \
  --out metadata/symbols.db
export STUBBORN_DB=metadata/symbols.db
stubborn-mcp
```

## Cursor configuration

`.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "stubborn": {
      "command": "stubborn-mcp",
      "env": {
        "STUBBORN_DB": "${workspaceFolder}/metadata/symbols.db"
      }
    }
  }
}
```

Module entry: `python -m stubborn_mcp`

## Tools
