Connect Prospero to Busabase
A native (C++/Dear ImGui) desktop coding harness for Windows, macOS and Linux by Chris Wellons (skeeto), announced 2026-10-31. It connects to a model provider you supply (no providers built in), supports subagents, MCP servers, Agent Skills (SKILL.md) and desktop control, and uses around two orders of magnitude less memory than web-stack harnesses. Free Community Edition on GitHub; a paid Professional Edition adds built-in headless engines for remote deployment.

Give your agent this one instruction
You end up with more than a connector: the busabase skill carries the whole change-request workflow, the CLI, and the full API — available in every future session without re-pasting anything.
Asks first
Busabase Cloud or Personal Desktop — your call, before anything happens.
Connects
Signs you in and stores the credential itself. No API key to copy by hand.
Seeds a Base
Creates and fills your first Base, so the workspace is not an empty screen.
Installs the skills
busabase and busabase-app-creator become permanent, for every session after this.
For this agent
Skills are the same SKILL.md directories as in Claude Code — frontmatter `name` and `description`, supporting files beside them — discovered in `.agents/skills` and the other harness directories, then `~/.config/prospero/skills`; typing `/NAME` in the prompt box invokes one directly. The directory the SETUP_SKILL.md installer writes to (`.agents/skills`) is one Prospero reads, at both project and home level.
Prefer a connector?
If you would rather wire Busabase in as MCP tools than let the agent install a skill, use the server URL below.

Prospero's agent can run shell commands and fetch URLs on your machine, so the Skill path applies. Start a session in your project folder (prospero .) and ask: Read https://busabase.com/SETUP_SKILL.md and set up Busabase for me. Approve the commands it proposes and the sign-in link in your browser, then ask it to verify the active account. Prospero discovers SKILL.md skills in .agents/skills (also .claude/skills, .cursor/skills, .codex/skills) from the working directory up to the repo root, and in ~/.config/prospero/skills.
Prefer a connector?
Add Busabase to ~/.config/prospero/prospero.ini:
[mcp busabase]
url = https://busabase.com/api/mcp
Then sign in from the server's page in Settings, or run prospero mcp auth busabase: Prospero discovers the authorization server, registers itself as a client and uses PKCE, keeping tokens in the state directory's mcp/auth (mode 0600). Prospero also reads a project's .mcp.json in Claude Code's format.
Prospero configuration documentation
Known gotchas
Remote MCP in Prospero is Streamable HTTP only — the old SSE transport is explicitly not supported (Busabase serves Streamable HTTP, so this does not block the connection above). Prospero ships with no model providers configured: connect your own endpoint or API key first, and a Claude subscription cannot be used. Each MCP tool call asks first unless the server is marked `trust = yes` in prospero.ini.

Written from this agent's own documentation. We have not re-run every step on a real machine, so check the linked docs if a command has changed.
Let your agent do the setup
One instruction, one authorization, and every change it makes afterwards carries a message and a diff you can check or revert.
