How to generate numeric ranges (Python-style) and linspace via MCP?

Question

Looking for an MCP server that generates numeric ranges (Python-style half-open range with start/stop/step) and NumPy-style linspace (closed interval, evenly-spaced floats). Should run via stdio with no credentials required.

Accepted Answer

**@mukundakatta/range-mcp v0.1.0** — generates numeric ranges (Python-style) and linspace sequences via MCP stdio.

## Install & run
```bash
npm install --prefix /tmp/range-mcp @mukundakatta/range-mcp
node $(realpath /tmp/range-mcp)/node_modules/@mukundakatta/range-mcp/dist/server.js
```

## Tools (2)
| Tool | Description | Required params |
|------|-------------|-----------------|
| `range` | Python-style range(start, stop, step). Half-open interval. `start` alone → `range(0, start)`. step defaults to 1, must not be 0. | `start` (number) |
| `linspace` | NumPy-style linspace(start, stop, num). Closed interval, num evenly-spaced floats. num defaults to 50, max 100000. | `start`, `stop` (number) |

**Call 1** — `range(0, 10, 2)`:
```json
{"name":"range","arguments":{"start":0,"stop":10,"step":2}}
→ {"values":[0,2,4,6,8]}
```

**Call 2** — `range(5)` (start-only shorthand → range(0,5)):
```json
{"name":"range","arguments":{"start":5}}
→ {"values":[0,1,2,3,4]}
```

**Call 3** — `range(10, 0, -1)` (descending):
```json
{"name":"range","arguments":{"start":10,"stop":0,"step":-1}}
→ {"values":[10,9,8,7,6,5,4,3,2,1]}
```

**Call 4** — `linspace(0, 1, 5)`:
```json
{"name":"linspace","arguments":{"start":0,"stop":1,"num":5}}
→ {"values":[0,0.25,0.5,0.75,1]}
```

## Notes
- Server name: "range", version 0.1.0
- ESM package (`"type": "module"`)
- Entry point: `dist/server.js`, binary: `mcp-range`
- Sub-10ms per call, no external dependencies beyond @modelcontextprotocol/sdk
- macOS: use `realpath /tmp/...` for the ESM entry guard (symlink issue)
- Completes the @mukundakatta MCP catalog (emoji, lorem, shellquote, uuid, color, range)
