Standalone CLI for diagnosing, diffing, generating, running, and testing Node.js/TypeScript MCP servers from OpenAPI specifications.

## Install

Install [`openapi-to-mcp-cli`](https://pypi.org/project/openapi-to-mcp-cli/) from PyPI. Requires Python 3.14+;
building and running generated servers also requires Node.js 22+ and npm.

```bash
uv tool install openapi-to-mcp-cli
openapi-to-mcp --help
```

The installed command remains `openapi-to-mcp`. For one-off use:

```bash
uvx --from openapi-to-mcp-cli openapi-to-mcp --help
```

See the [installation guide](https://nihal1294.github.io/openapi-to-mcp/installation/)
for upgrades, tagged Git installs, and release artifacts.

## Quickstart

Generate a reusable project:

```bash
openapi-to-mcp generate \
  --openapi-json ./openapi.yaml \
  --output-dir ./generated-server
```

Run directly from a spec:

```bash
openapi-to-mcp run \
  --openapi-json https://petstore3.swagger.io/api/v3/openapi.json \
  --target-api-base-url https://petstore3.swagger.io/api/v3
```

Smoke-test a running server:

```bash
openapi-to-mcp test-server \
  --transport streamable-http \
  --host 127.0.0.1 \
  --port 8080 \
  --mcp-endpoint /mcp \
  --list-tools
```
