Install & config
Client config (built from the install command this repo gives)
{
"mcpServers": {
"seasons-ai-osen": {
"command": "npx",
"args": ["council"]
}
}
}Parsed from the README we fetched on 2026-10-26; we have not executed it.
command/args come from the install command the repository states. When it is ambiguous, the project README wins.
VS Code (.vscode/mcp.json - the key is servers)
{
"servers": {
"seasons-ai-osen": {
"command": "npx",
"args": ["council"]
}
}
}Same server, but VS Code keeps it under <code>servers</code>.
Claude Code (command line)
claude mcp add --transport stdio seasons-ai-osen -- npx council
Claude Code does not read a config file; add the server with this command.

以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →
Claude, Codex and any OpenAI-compatible model take turns on your problem. Each turn amends one shared solution, accepts it or objects. The session ends when every participant accepts the same version — or tells you plainly that they did not.
> Early. Built for one owner on macOS. Every mechanism is tested on scripted participants with zero model calls; acceptance on real providers is in progress.
## How it works
The engine runs the discussion, not the models. Turn order, who agreed and when the session ends are decided by code. A model cannot declare consensus in prose.
Nothing is lost. A session is a journal of events; its state is rebuilt from the journal, so a killed process is resumed where it stopped.
Participants are sealed. No tools, no MCP servers, no access to your disk. Your files reach them only as text, through the engine.
You stay in the loop. Add a remark mid-discussion, answer the models' questions, pause after each round, or pick a version yourself.
## Download
You need macOS on Apple Silicon and at least one participant: the claude or codex CLI signed in, or an OpenAI-compatible endpoint. Node is not needed for the app. From the first release after 0.10.0 the osen MCP server and the council command also run from the app bundle without Node; in 0.10.0 and earlier they need a clone of the repository. Running from a clone of the repository still needs Node 22.18+ (see "From source").
1. Download osen- -arm64.dmg from the latest release.
2. Open the image and drag Osen to "Applications".
3. Open Osen. The app has no Apple developer signature, so the first time macOS refuses to open it: press "Done", then open "System Settings" → "Privacy & Security", scroll down and press "Open Anyway". Later launches open normally.
If macOS says the app is damaged, run xattr -dr com.apple.quarantine /Applications/Osen.app in Terminal and open it again. Details and updates: docs/deploy.md.

bash
git clone https://github.com/seasons-ai/Osen.git
cd Osen
npm install
npm run desktop
The window opens on "History"; press "New" to start a discussion. To build the .dmg yourself: npm run dist, then docs/deploy.md.
Try it without spending anything — two scripted participants, 0 model calls:
bash
COUNCILDEV=1 COUNCILHOME=.council-data npx council --topic "Should the README lead with the product or with the install steps?" --participant scripted:packages/core/scenarios/readme/p1.json --participant scripted:packages/core/scenarios/readme/p2.json --max-rounds 3
console
── Turn 1 · round 1 · p1 «Participant 1» · amend → version 1
Arguments: A reader decides in the first screen. Say what the product is and show one real run; install comes next.
── Turn 2 · round 1 · p2 «Participant 2» · amend → version 2
Arguments: Agreed on the order, but the reference still makes the page a wall of text. Move it to docs/ and link it.
── Turn 3 · round 2 · p1 «Participant 1» · agree
Arguments: Moving the reference out keeps the first screen short. I agree.
