arifOS — Claude Code MCP server: verdicts before action
arifOS checks an AI agent’s consequential proposals against constitutional rules before execution and records the verdict. A human keeps the veto.
claude mcp add --transport http arifos https://mcp.arif-fazil.com/mcpWhat arifOS — Constitutional AI Kernel does
arifOS evaluates proposals against thirteen floors and returns a governed verdict before an action runs. It separates judgment from execution: another component carries out actions, while a human retains veto authority. Agents access the service through MCP tools, with verdicts recorded as receipts.
The project describes a hash-chained VAULT999 audit trail. arifOS does not replace authentication, sandboxing, or legal review. That boundary matters when an agent can take real actions; a verdict alone does not provide those safeguards.
The server can connect to Claude Code, Codex, Cursor, and the other listed platforms. In Claude Code, add it with claude mcp add --transport http arifos https://mcp.arif-fazil.com/mcp.
What it helps with
- review an agent proposal before it runs
- record a governed verdict for later auditing
- keep a human veto over agent actions
- separate proposal review from execution
Example prompts for the agent
- Check this proposal before execution and record the verdict.
- Review the proposed action under arifOS, then wait for my approval.
- Save the outcome of this check as an audit receipt.
