The context layer for analytics agents
---
KTX turns warehouse metadata, semantic definitions, and business knowledge into
reviewable project files that agents can use to plan, query, and update
analytics work.
Use KTX when you want agents to:
- Generate SQL from approved measures and joins
- Repair semantic definitions through reviewable diffs
- Explain metric provenance with warehouse evidence
- Work alongside dbt, MetricFlow, LookML, Looker, Metabase, and Notion
Supports PostgreSQL, Snowflake, BigQuery, ClickHouse, MySQL, SQL Server, and
SQLite.
## Quick Start
```bash
pnpm add --global @kaelio/ktx
ktx setup
ktx status
```
`ktx setup` creates or resumes a local KTX project, configures providers and
connections, builds context, and installs agent integration.
## Common Commands
| Command | Purpose |
|---------|---------|
| `ktx setup` | Create, resume, or update a KTX project |
| `ktx status` | Check project readiness |
| `ktx connection list` | List configured connections |
| `ktx connection test ` | Test one connection |
| `ktx ingest ` | Build context for one connection |
| `ktx ingest --all` | Build context for every configured connection |
| `ktx ingest text ` | Capture free-form notes into memory |
| `ktx sl list` | List semantic-layer sources |
| `ktx sl search "revenue"` | Search semantic-layer sources |
| `ktx sl validate --connection-id ` | Validate a semantic source |
| `ktx sl query --measure --format sql` | Compile semantic-layer SQL |
| `ktx wiki search "revenue definition"` | Search local wiki context |
| `ktx mcp start` | Start the local MCP server for agent clients |
Project resolution defaults to `KTX_PROJECT_DIR`, then the nearest `ktx.yaml`,
then the current directory. Pass `--project-dir ` when scripting.
## Project Layout
```text
my-project/
├── ktx.yaml # Project configuration
├── semantic-layer// # YAML semantic sources
├── wiki/global/ # Shared business context
├── wiki/user// # User-scoped notes
├── raw-sources// # Ingest artifacts and reports
└── .ktx/ # Local state and secrets, git-ignored
```
Commit `ktx.yaml`, `semantic-layer/`, and `wiki/`. Keep `.ktx/` local.
## Agent Usage
Setup can install KTX instructions for Claude Code, Codex, Cursor, OpenCode,
and universal `.agents` clients:
```bash
ktx setup --agents --target codex
```
Agent-facing workflows typically start with:
```bash
ktx sl search "revenue" --json
ktx wiki search "refund policy" --json
ktx sl query --connection-id warehouse --measure orders.revenue --format sql
```
## Development
```bash
git clone https://github.com/kaelio/ktx.git
cd ktx
pnpm install
uv sync --all-groups
pnpm run build
pnpm run check
```
Use the development CLI locally:
```bash
pnpm run setup:dev
pnpm run link:dev
ktx-dev --help
```
KTX is a pnpm + uv workspace:
- TypeScript packages live in `packages/*`
- CLI source lives in `packages/cli`
- Python runtime source lives in `python/ktx-sl` and `python/ktx-daemon`
- Public docs live in `docs-site/content/docs`
Useful checks:
```bash
pnpm run type-check
pnpm run test
pnpm run dead-code
uv run pytest -q
```
