Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Randomness from outside the model, so one prompt gives different answers that still fit the ask.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.
The GitHub repo last changed –, and the latest version (1.0.4) reached the registry yesterday.

Ask a language model for the same thing ten times and you get the same answer ten times. Model Salt is an MCP server that gives your model randomness from outside it, so one prompt gives ten different answers that still do exactly what you asked.

One command adds it to your client. Run it once.
| Client | Command |
|---|---|
| Claude Code | npx -y @modelsalt/model-salt setup claude |
| Codex | npx -y @modelsalt/model-salt setup codex |
| Gemini CLI | npx -y @modelsalt/model-salt setup gemini |
| Kimi Code | npx -y @modelsalt/model-salt setup kimi |
Start a new session in your client after it, and the model_salt tool is there.
model-salt server in your client's MCP list. For Codex and Kimi Code it also adds a short skill at ~/.agents/skills/model-salt/ that tells the model when to call the tool, and for Codex one setting on that server so the model sees the tool from the start.--dry-run to print what it would change and change nothing.npx -y @modelsalt/model-salt uninstall claude # or codex, gemini, kimi
It takes out everything setup added. The skill stays while another client of yours still uses it. --dry-run works here too.
Ask for anything with room for choices: a picture, an SVG, a page, a name, a story, a plan. The model calls model_salt with your request, gets back what to settle this time, and then does your request as you asked it.
Want more or less of it? Say so in your prompt ("make it really different", "keep it close to the usual"). The tool takes a setting from 0 to 2. Left out, it is 1.
| Setting | How often each choice keeps the model's usual pick (target) |
|---|---|
| 0 | always |
| 0.5 | 70% of the time |
| 1 (default) | 45% of the time |
| 1.5 | 25% of the time |
| 2 | no more often than any other fitting pick |
The model skips the tool for questions with one right answer (a sum, a fact, a bug fix).
Keep what you like. Like part of a result? Say what to keep in plain words ("keep the palette and layout, give me new illustrations"). Your model copies those decided answers from the earlier Model Salt reply into the tool's keep field and calls it again. Only the open choices are rolled again, and the reply starts with one line, e.g. Kept: palette = burnt orange on cream; layout = split screen, text left. That holds on later runs until you say start fresh, and "give me something new" leaves it out. In a new chat, paste the Kept: line or say it in your own words. A kept answer that no longer fits a new request is dropped, and the reply says so. Nothing is stored on our side.

Randomness from outside the model picks one answer per question. Your model then does the request with those answers settled. More, and why simpler ways failed: docs/how-it-works.md.
