# mcp-gateway — MCP Gateway

## Package scope and prerequisites

This catalog ships instructions, not the executable runtime. Python modules, scripts, local services and optional tools named below must be installed separately from the upstream project. Check their availability before running commands; if they are missing, explain the prerequisite instead of claiming execution or results. The host agent may use model tokens while following these instructions.

Expose l'ensemble des skills the toolkit comme outils MCP (Model Context Protocol).
Un seul point d'entrée pour que n'importe quel agent (Claude Code, Codex, Cursor, etc.)
découvre et utilise toutes les capacités de Botte.

## Concept

```
Client MCP (Claude Code / Codex / Cursor)

mcp_gateway (stdio JSON-RPC)

    ├── security_scanner    → scan . --format json
    ├── fast_context        → explore . "find imports"
    ├── meta_harness        → run plan agents
    ├── botte_nn            → predict model input
    ├── solvers             → assign / pack / schedule
    ├── context_budget      → optimal context budget
    ├── nlp_deterministic   → classify / extract
    └── … (auto-discover)
```

## Usage

```bash
# Test en local
python -m skills.mcp_gateway.server

# Avec un client
python -m skills.mcp_gateway.cli call security_scanner '{"root": ".", "fail_on": "critical"}'
python -m skills.mcp_gateway.cli call fast_context '{"root": ".", "query": "find imports"}'
python -m skills.mcp_gateway.cli list
```

## Configuration

Fichier `.botte-cache/mcp_gateway.json` :

```json
{
  "enabled_skills": ["security_scanner", "fast_context", "solvers"],
  "excluded_skills": []
}
```

Si non configuré, toutes les skills disponibles sont exposées.
