# odgs-mcp-server

Hooks an AI agent up to the ODGS engine: payloads get checked against governance rules, maturity gets scored, and signed S-Certs come back.

## What it does

The server speaks stdio, so any MCP client can drive it. The free tier ships `validate_payload`, `validate_batch`, `list_packs`, `governance_score` and `conformance_check`. Each payload check returns a signed S-Cert, which is what makes the result auditable rather than just a log line.

The maturity score covers eight ISO/IEC 38505-1 and ISO/IEC 25012 pillars, from 0 to 100, with a per-pillar gap breakdown. Install the separate `odgs-maturity` package or the score falls back to a built-in heuristic.

Regulation compilation, semantic drift detection, conflict detection and rule harvesting from Databricks, Snowflake and Collibra sit behind a Certified Pack licence. Those tools read the key from `ODGS_API_KEY`. Point `ODGS_PROJECT_ROOT` at your project directory in the client config.

## Requirements
- Needs: Python and uv (commands run via uvx)
- Environment variables: `ODGS_PROJECT_ROOT`, `ODGS_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add --env ODGS_PROJECT_ROOT=<ODGS_PROJECT_ROOT> --env ODGS_API_KEY=<ODGS_API_KEY> --transport stdio odgs-mcp-server -- uvx odgs-mcp-server
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from odgs-mcp-server <command>

### Codex

**Platform CLI**
```bash
codex mcp add odgs-mcp-server --env ODGS_PROJECT_ROOT=<ODGS_PROJECT_ROOT> --env ODGS_API_KEY=<ODGS_API_KEY> -- uvx odgs-mcp-server
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from odgs-mcp-server <command>

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "odgs-mcp-server": {
            "command": "uvx",
            "args": [
                "odgs-mcp-server"
            ],
            "env": {
                "ODGS_PROJECT_ROOT": "<ODGS_PROJECT_ROOT>",
                "ODGS_API_KEY": "<ODGS_API_KEY>"
            }
        }
    }
}
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from odgs-mcp-server <command>

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "odgs-mcp-server": {
            "type": "stdio",
            "command": "uvx",
            "args": [
                "odgs-mcp-server"
            ],
            "env": {
                "ODGS_PROJECT_ROOT": "<ODGS_PROJECT_ROOT>",
                "ODGS_API_KEY": "<ODGS_API_KEY>"
            }
        }
    }
}
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from odgs-mcp-server <command>

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add -e ODGS_PROJECT_ROOT=<ODGS_PROJECT_ROOT> -e ODGS_API_KEY=<ODGS_API_KEY> odgs-mcp-server uvx odgs-mcp-server
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from odgs-mcp-server <command>

## When to use it
- check a data payload against governance rules and get a signed S-Cert
- score project governance maturity across eight ISO pillars and see the gaps
- validate several payloads together in one call
- run the ODGS conformance self-check at L1 or L2
- turn regulation text into valid ODGS rule JSON under a licence

## Example prompts
- Run `validate_payload` on this dataset and show me the S-Cert
- Score the project with `governance_score` and break down the pillar gaps
- Compile the regulation text into ODGS rules with `compile_regulation`
