# fibo-mcp

Give your financial agent access to the Financial Industry Business Ontology (FIBO).

Paste into Claude Code:
```
Install fibo-mcp from https://github.com/NeuroFusionAI/fibo-mcp
```

## Installation

If already in fibo-mcp directory, skip clone and cd. Run all commands from the fibo-mcp directory:
```bash
git clone https://github.com/NeuroFusionAI/fibo-mcp.git && cd fibo-mcp
uv sync
claude mcp add --scope user fibo-mcp -- uv run --directory "$(pwd)" main.py
# Restart Claude Code to load the MCP
```

### With OWL-RL Materialization (Recommended for symbolic reasoning)

Materialization applies the OWL-RL profile and caches the inferred graph. Triple
counts depend on the pinned FIBO revision. OWL-RL is a scalable subset of OWL,
not unrestricted or complete OWL reasoning.

```bash
# Step 1: Build cache first (Ctrl+C after "Ready to serve")
uv run main.py --materialize

# Step 2: Add MCP (instant startup from cache)
claude mcp add --scope user fibo-mcp -- uv run --directory "$(pwd)" main.py --materialize
```

### Diagramming Skill

The repo includes a diagramming skill (`.claude/skills/diagramming_expert/`) for ASCII visualizations.

When installing via Claude Code, ask user:

> **Diagramming skill scope:**
> - [ ] Project scope only (default - already in .claude/skills/)
> - [ ] User scope (all projects) - copy to ~/.claude/skills/

```bash
# User scope skill (optional)
cp -r .claude/skills/diagramming_expert ~/.claude/skills/
```

### Other MCP Clients (Cursor, Claude Desktop, etc.)

Add to your MCP config file:

```json
{
  "mcpServers": {
    "fibo-mcp": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/fibo-mcp", "main.py"]
    }
  }
}
```

With materialization:
```json
{
  "mcpServers": {
    "fibo-mcp": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/fibo-mcp", "main.py", "--materialize"]
    }
  }
}
```

> Build cache first: `uv run main.py --materialize` (Ctrl+C after "Ready to serve")

### Uninstall

```bash
# Claude Code
claude mcp remove fibo-mcp

# Remove user-scope skill (if installed)
rm -rf ~/.claude/skills/diagramming-expert
```

### "What is money?"

Money is a medium of exchange, a store of value, and a unit of account that facilitates economic transactions.

**Forms of Money:**
- Commodity money - Physical items with intrinsic value (gold, silver)
- Fiat money - Government-issued currency not backed by commodity (USD, EUR)
- Digital/Electronic money - Bank deposits, digital payments
- Cryptocurrencies - Decentralized digital assets like Bitcoin

Money's value ultimately rests on collective trust and acceptance.

According to FIBO:

**Currency**: *"medium of exchange value, defined by reference to the geographical location of the monetary authorities responsible for it"*

FIBO distinguishes:
- **Currency** - the medium of exchange itself
- **Monetary Amount** - a quantity denominated in a currency
- **Currency Identifier** - ISO 4217 codes (USD, EUR, etc.)

A country is a distinct territorial body or political entity with its own government, defined borders, and sovereignty.

**Key characteristics:**
- Defined territory
- Permanent population
- Government
- Sovereignty
- Recognition by other countries

There are approximately 195 recognized countries today.

**Sovereign State**: *"non-physical juridical entity that is represented by one centralized government that has sovereignty over a geographic area"*

Key characteristics from FIBO:
- Represented by one centralized government
- Has a permanent population
- Has defined territory
- Has capacity to enter into relations with other sovereign states

A corporation is a legal entity separate from its owners:

- **Limited liability** - Owners not personally responsible for debts
- **Perpetual existence** - Continues regardless of ownership changes
- **Legal personhood** - Can own property, enter contracts, sue and be sued

## Why FIBO?

Finance has a semantics problem—the same "trade," "counterparty," or "position" can mean different things across desks, systems, vendors, and jurisdictions. FIBO provides a formal, machine-readable ontology (OWL/RDF) so data from contracts, market feeds, and internal systems can be integrated and queried with shared meaning.

Contributors include Citigroup, Deutsche Bank, Goldman Sachs, State Street, Wells Fargo, CFTC, US Treasury OFR, and others. Standardized by EDM Council and OMG.

## HTTP MCP (local by default)

The HTTP listener binds to `127.0.0.1` by default. Do not expose it directly to
the internet: the server accepts read-only SPARQL and caps returned rows, but it
does not provide application authentication or rate limiting. Put an
authenticated, rate-limited gateway in front of it before any remote use.

```bash
# Start HTTP server
uv run main.py --http --port 8000

```

## Technical Details

| | |
|---|---|
| Data | 299 RDF/OWL source files at the pinned revision; loaded triple count is logged at startup |
| Base graph | 133,498 triples; 3,346 `owl:Class` subjects; 1,216 typed RDF/OWL properties; 16,665 URI subjects |
| Cache | `./data/fibo.ttl` (base), `./data/fibo_materialized.ttl` (with --materialize) |
| Source revision | `f59157fe156e3d91b1c045222d0a7dc06b7d78a2` by default; override with `FIBO_REVISION` |
| Refresh cache | `uv run main.py --force-download` |

### Server Flags

| Flag | Description |
|------|-------------|
| `--materialize` | Enable OWL-RL inference (adds startup time; the materialized graph is cached) |
| `--bm25-top-k N` | Number of BM25 search results (default: 10) |
| `--force-download` | Re-download the configured FIBO revision |
| `--http` | Run as HTTP server instead of stdio |
| `--port N` | HTTP server port (default: 8000) |
