## Which one, for what

### OpenMausBot (B)

Good for: A person or an outside agent who wants several CLI agents (Claude Code, Codex, Grok, ACP CLIs) organised as named bots with their own computers, routines and approvals, driven by MCP or a CLI.

Ahead on:
- Reliability, 60 against 43
- Schema & documentation, 90 against 45
- Agent ergonomics, 77 against 50

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: New bots start at Full access, which approves provider permission requests without a card

### Sculptor (D)

Good for: Developers who want parallel coding agents in isolated workspaces and are fine with a research preview.

Ahead on:
- Payments & pricing, 60 against 50

Also in its favour:
- No key needed to call it

Watch for: Labelled an experimental research preview that may change drastically


## Why the edge

### Schema & documentation: OpenMausBot +45

- OpenMausBot (90): The MCP server's 20 tools each have a JSON Schema input with `additionalProperties: false` and required fields marked. No OpenAPI for the local HTTP API (25). Markdown docs in the repository, and the docs app's source serves llms.txt, llms-full.txt and Markdown routes. docs.openmausbot.com disallows every crawler, so the live llms.txt was not read (10). Descriptions state purpose and limits, such as that `update_bot_profile` cannot alter permissions, that `send_bot_message` may make the bot use external tools and that `edit_bot_message` is refused while a thread works, and the server instructions say to read before mutating. Few say when not to use a tool (15). Integer limits with minimum and maximum, an enum on `scope`, a pattern on `send_id` and `oneOf` shapes for responders (13). JSON configuration examples for each install path, the wait statuses and job states, CLI exit codes and a `{ ok, error, hint, exitCode }` failure shape (12). MCP server version 1.1.0, release notes per version and a changelog page in the docs (15).
- Sculptor (45): Harness reading. A README, specs and agent docs in the repository; no API reference (45).

### Agent ergonomics: OpenMausBot +27

- OpenMausBot (77): 20 tools, inside the 11 to 30 band, with annotations that separate reads from writes but no toolsets or read-only mode to load. Transcript reads are bounded and never return screenshot pixels (17). `limit` up to 200 messages, search capped at 100 hits, `task_id` and `scope` filters, and `since_ms` and `after_version` to keep watching a job (17). `wait_for_conversation` reports settled, needs-user, failed, stalled or timed-out with a redacted transcript tail, and the CLI's exit codes separate a pending approval from a timeout. We did not read every MCP error path (15). `send_id` makes a repeated send return the first receipt, `wait` is held by the server rather than polled, and every tool carries readOnlyHint, destructiveHint, idempotentHint and openWorldHint (20). Few required parameters and defaults for task, limit and timeout. The server answers only while the app or `openmausbot serve` runs, mutating tools need a paired token in packaged builds, and there is no client SDK beyond the CLI (8).
- Sculptor (50): Harness reading. Workspaces as isolated copies, review and merge back, and built-in skills (50).

### Reliability: OpenMausBot +17

- OpenMausBot (60): Read as local software. Official npm package `openmausbot` (Node.js 24 or newer) and signed, notarised macOS builds, a Windows installer and Ubuntu 24.04 packages, with supported platforms and a capability table in the README (20). 2,075 test files and a CI workflow on main. Of the last 23 finished CI runs on main on 30 October 2026, 10 passed, 3 failed and 10 were cancelled by newer pushes in a serialised queue (20). 365 open issues against about 3,940 issues and pull requests filed since 11 August, so most are closed, but the 25 newest open issues include several bug reports from 29 and 30 October with no reply yet (15). Release notes for every version in New, Easier and Fixed sections, but new capabilities ship in 0.1.x patch versions and no release marks breaking changes (5). Version 0.1.134, and the README calls the project early (0).
- Sculptor (43): Local software. Desktop downloads for Mac (Apple Silicon), Linux and Linux ARM64 (20). checks.yml and a PR gate run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). sculptor-v tags up to v0.49.0, no changelog file (8). 0.x and labelled a research preview (0). 20 + 15 + 0 + 8 + 0 = 43.

### Payments & pricing: Sculptor +10

- OpenMausBot (50): No payment protocol (0). MausBot Cloud, the hosted option, is priced by plan on a public page ($15, $49 and $99 a month, Team $169 and Business $599, or Business self-hosted $299 a month billed yearly, re-read on 2 November), with extra computer-hours at $0.05 each, so plan pricing (10). The app is free with no card or account (20). `npx openmausbot` installs and starts it with no signup (20).
- Sculptor (60): Free self-hosted software with nothing to buy, so 0 for a protocol and 20 each for public pricing, a free tier and onboarding with no sign-up, 60.

## Verdicts

**OpenMausBot.** A bounded 20-tool MCP server with typed schemas, annotations and idempotent sends, and a headless CLI with JSON output and exit codes, let another agent hand work to a bot team and wait on it. New bots start at Full access, so provider permission requests pass without a card, and usage analytics stay on until switched off.

**Sculptor.** Imbue's open-source app for parallel coding agents in isolated workspaces, with telemetry off until you choose otherwise. It's an experimental research preview that warns of bugs and drastic changes, Mac and Linux only, with no changelog.

## Before you call either

### OpenMausBot

1. Ask the owner for a pairing code from Settings > Phone, exchange it at `POST /api/auth/pair`, and set `OPENMAUSBOT_TOKEN` with an explicit `OMB_PORT`
2. Pass a `send_id` with every `send_bot_message` and `send_channel_message`, so a retry returns the first receipt
3. Use `wait_for_conversation` instead of polling, and on `needs-user` stop and tell the owner a card is waiting
4. Check a bot's access level with the owner before sending work. New bots run at Full access unless defaults were changed
5. Ask the owner to switch off Settings > General > Usage analytics if nothing beyond model calls should leave the machine

### Sculptor

1. Download from the README's links, connect a repository and create a workspace before prompting
2. Review the diff before merging a workspace back to main
