# Data Olympus

Data Olympus gives agents a Git-backed collection of engineering standards and decisions to consult while working on a project. Use it when existing team choices should guide new work.

## What it does

The knowledge base is made of Markdown files with YAML frontmatter and lives in Git. Its MCP server lets an agent look up a relevant standard or architectural decision; the CLI can create a bundle, lint its contents, and build an index. It targets decision lookup, not code search or finding where a symbol is used.

The format works with Open Knowledge Format v0.2 consumers and adds governed document fields and links between superseded decisions. Proposed edits pass through a queue before commit, while the MCP write pipeline uses a single writer. Python 3.13+ and `uv` are required; the quickstart commands depend on both.

## Requirements
- Needs: Python and uv (commands run via uvx)
- Environment variables: `KB_MAIN_PATH`, `KB_INDEX_PATH`, `KB_HTTP_PORT` — 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 KB_MAIN_PATH=<KB_MAIN_PATH> --env KB_INDEX_PATH=<KB_INDEX_PATH> --env KB_HTTP_PORT=<KB_HTTP_PORT> --transport stdio data-olympus -- uvx data-olympus
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from data-olympus <command>

### Codex

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

### Cursor

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

### GitHub Copilot

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

### Gemini CLI

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

## When to use it
- look up an accepted architectural decision
- check a library choice against team standards
- create a Markdown knowledge base
- lint and index knowledge-base documents

## Example prompts
- Check the knowledge base for an accepted decision about choosing a library for this project.
- Find the standard that should guide this database migration.
- Create a knowledge base in `my-kb` and lint its documents.
