#approval

Marchward is an Apache-2.0 open-source runtime authority for AI agents. It routes an agent's tool calls through one control point: credential mediation (the agent holds a single Marchward key and never your real downstream credentials), an inference spend cap enforced before the call reaches the provider, human-in-the-loop approval gates on irreversible actions, and a tamper-evident hash-chained audit log. Public repo and packages are live (npm @marchward/*, PyPI marchward, official MCP registry ai.marchward/mcp-server), with a runnable governed-LangGraph example in the repo.

Shinobi gives every AI coding agent on your machine — and every cloud Claude session — one shared task spine, decision log, and searched dead-ends ledger. Every failed approach is logged and semantically checked before an agent proposes a similar one, so agents stop repeating mistakes across sessions. Adds mobile approvals (request_approval pushes to your phone) and an autonomous dispatch/swarm that drains the backlog with N parallel agents in isolated git worktrees, all sharing one brain. Local-first SQLite over stdio, or remote streamable-HTTP MCP you can self-host for $0/mo. 39 tools, plugin system, MIT. Works with Claude Code, Claude Desktop, Cursor, Cline, Continue.dev, Zed.
