# Command Center

Your company's purchased productivity tools, inventoried once — then usable as a
**second brain** by any AI assistant. One repo, one source of truth, zero per-seat AI tax.

## The idea

Every company pays for a sprawl of tools — email providers, campaign platforms, team
chat — and nobody holds the full picture. Command Center fixes that in two layers:

1. **Inventory** — `inventory.yaml` records every purchased tool: plan, seats, cost,
   owner, renewal date. `discovery/` scripts detect what's actually in use (MX/DNS
   checks, expense keyword lists) so the inventory stays honest.
2. **Second brain** — `brain/server.py` is an MCP server. Claude Desktop, ChatGPT,
   Cursor and friends connect to it and can answer *"which tools do we pay for that
   do the same thing?"* or *"what renews next quarter?"* straight from your inventory,
   as typed context packets. Read-only by design.

## Repo map

| Path | What it is |
|---|---|
| `catalog/tool-catalog.md` | Curated catalog: 19 email/campaign/comms tools with verified API auth, base URLs, and passive discovery signals |
| `discovery/mx_discover.py` | Passive email-provider detection via MX + SPF records (no credentials) |
| `inventory.example.yaml` | The inventory schema — copy to `inventory.yaml`, fill in your stack |
| `brain/server.py` | MCP server: `list_stack`, `get_tool_context`, `find_overlap`, `stack_summary` |
| `requirements.txt` | `fastmcp`, `dnspython`, `pyyaml` |

## Quickstart

```bash
python3 -m venv .venv && .venv/bin/pip install -r requirements.txt

# 1. Detect a company's email provider (passive, no credentials)
.venv/bin/python discovery/mx_discover.py zoho.com

# 2. Record your stack
cp inventory.example.yaml inventory.yaml   # then edit it

# 3. Start the second brain (stdio MCP server)
.venv/bin/python brain/server.py
```

Register `brain/server.py` as an MCP server in Claude Desktop
(Settings → Connectors → Add custom connector) or ChatGPT (Settings → Apps / MCP).
Both speak MCP natively — one server, both assistants.

## Why this, why now

SaaS inventory tools (Zylo, Torii, Vertice) are enterprise-quote-only with $50K+
floors. AI search tools (Glean) can't act; agent tools (Moveworks) cost six figures.
And cloud second brains can vanish overnight — Limitless was acquired by Meta and
shut down in Dec 2025. This is the MIT-licensed, self-hosted, MCP-native alternative:
your context layer, owned by you. Tokens are rented. Context is owned.

## Roadmap

- OAuth connector guides per catalog tool (least-privilege scopes)
- Expense CSV import → auto-suggest inventory entries
- Renewal reminders (scheduled brief)
- Tiny web dashboard over `inventory.yaml`
