### Description (declared)

# willow-mcp

[![PyPI](https://img.shields.io/pypi/v/willow-mcp)](https://pypi.org/project/willow-mcp/)
[![License: Apache 2.0](https://img.shields.io/badge/License-Apache_2.0-blue.svg)](LICENSE)

Agent-neutral MCP server with persistent memory and task execution. Works with any MCP client: Claude Code, Claude Desktop, Cursor, or any custom agent that speaks stdio MCP.

> **Corpus memory:** the whole Willow constellation — the code, human, and collaboration corpora assembled and queryable — lives in the sovereign [`willow-compose`](https://github.com/rudi193-cmd/willow-compose) repo. The hub *calls* it; it doesn't live here (keeping the hub lean).

**Three storage backends in one server:**
- **SOIL store** — SQLite-backed local key/value store with full-text search and soft delete
- **Postgres knowledge base** — multi-keyword searchable knowledge graph
- **Kart task queue** — sandboxed task executor for shell commands and scripts

Every tool call is authorized via a filesystem-based manifest ACL — no ACL database, no external auth service. See [Authorization](#authorization).

## Install

```bash
pip install willow-mcp
```

Requires Python 3.11+. Postgres is optional — SOIL store works standalone.

```bash
willow-mcp-init    # scaffold $WILLOW_HOME (idempotent)
willow-mcp-compile --force   # compile manifests (use product venv — see below)
willow-mcp-sign-seed hanuman # ratify home seed + detach-sign (operator terminal only)
willow-mcp-compile-persona hanuman # seed → personas/hanuman.md (AS-7)
```

### Local sandbox (one command)

To take a fresh clone to a working stdio server — venv, editable install,
scaffolded `$WILLOW_HOME`, compiled manifests, and (best-effort) a local
Postgres with every table created — run:

```bash
bash scripts/sandbox-bootstrap.sh   # idempotent; ends with a live diagnostic_summary
```

On a bootstrapped sandbox the schema mappings for the tables the scr…
