Dials — a behavior control panel for Claude

Give Claude a set of 0–10 sliders — rigor, verification, verbosity, autonomy — that it reads over MCP and actually follows. Tune how Claude works from the outside, as data, instead of re-typing "be more thorough / just ship it / double-check everything" in every chat. The settings persist across sessions and work in Claude Code, Claude Desktop, and claude.ai.

Free. MIT. Zero dependencies.

Why

How Claude behaves is normally buried in prose — system prompts, CLAUDE.md, whatever you remember to say. Prose can't be dialed. Dials turns the tunable dimensions into numbered sliders exposed as MCP tools + a resource. Slide one, and every task after it changes. That's a control plane for the model, not a notes file.

The dials

Each value maps to a concrete instruction (see dials://schema), so Claude gets an unambiguous directive, not a vibe.

Presets

• default — balanced baseline

• fable — maximum rigor: read everything, verify with evidence, self-critique; terse replies, meticulous work

• ship — fast and autonomous, for low-stakes velocity

• careful — high-stakes: verify everything, ask before acting, max caution

• explore — research/prototyping: reach wide, try new things

Tools

get_dials · set_dial(dial, value) · apply_preset(preset) · list_presets · explain_dial(dial) · reset_dials

And a resource dials://current (the live settings as Markdown) + dials://schema (full JSON), plus a load-dials prompt.

Install

Drop CLAUDE.md into a repo to make Claude read your dials at the start of every task.

Use it

"get my dials" · "set rigor to 9" · "apply the careful preset" · "explain the autonomy dial"

Or just talk: "double-check everything from now on" → Claude bumps verification.

Design notes

• Zero dependencies. The MCP wire protocol (JSON-RPC 2.0 over stdio + Streamable HTTP) is implemented directly. No SDK, no supply-chain surface, instant npx.

• State lives at ~/.claude-dials/state.json (override with DIALS_STATE_FILE). Corrupt or missing state falls back to defaults — a config tool must never take down the client.

• Remote auth. The HTTP transport takes an optional DIALS_TOKEN bearer token; unset = open (local dev only).

Verify it yourself

npm test

Spawns the real server over stdio and drives a full JSON-RPC handshake — 30+ assertions across initialize, tools, resources, prompts, persistence, schema enforcement, and error paths. Also: npm run eval (mock obedience gate) / npm run eval:live (real Claude, costs tokens).
