Datanika Core MCP Server

Datanika

Open-source data pipeline platform — Extract, Load, Transform, and Orchestrate from a single UI.

Datanika combines dlt (extract + load) with dbt-core (transform) and adds visual pipeline management, scheduling, and monitoring — all in one Python-native platform.

Think Airbyte + dbt Cloud + Airflow — in one tool, self-hostable with Docker Compose.

Quick Start

Docker (recommended)

git clone https://github.com/datanika-io/datanika-core.git
cd datanika-core
cp .env.example .env
# Edit .env with your settings
docker compose up -d

App available at http://localhost:3000

Development

uv venv && source .venv/bin/activate
uv pip install -e ".[dev]"
docker compose up -d postgres redis  # infrastructure only
uv run reflex run                     # starts on :3000 + :8000

Releases & versioning

Datanika uses 0.x SemVer with tagged releases (v0.1.0, …). While pre-1.0, breaking changes bump the minor. There is no 1.0 yet — that will mean a committed, stable public API contract.

Self-hosting? Pin a release instead of tracking master. master is continuously deployed to our hosted app and moves several times a day.

git checkout v0.1.0                                    # source
docker pull ghcr.io/datanika-io/datanika-core:v0.1.0   # image (:latest follows master)

Every version's notes are on the Releases page. Security advisories cite the first patched release (e.g. Patched: v0.1.0), so a pinned tag tells you immediately whether you're affected.

The datanika-mcp sub-package is versioned and released independently (mcp-v* tags, published to PyPI).

Tech Stack

Roadmap

• 36 connectors (databases, SaaS APIs, files, streaming)
• dbt transformations, tests, snapshots, packages
• REST API v1 with OpenAPI/Swagger and typed per-connector inline schemas
• AI-agent compatibility (/llms.txt, agent-guide, 5-tier API, golden-path loop, ?wait=true, Idempotency-Key, run cancel, MCP server)
• Pipeline templates (one-click setup)
• In-app notification center with Slack, Telegram, Email, Webhook channels
• SSO (SAML/OIDC) for Enterprise
• Usage-based billing (cloud plugin)
• 2,300+ tests across unit, security, and E2E (SQLite in-memory for speed)
• Kubernetes Helm chart — in-tree at deploy/helm/datanika/; installs the same image as the Compose path. Bundled Postgres/Redis are single-replica and not production-grade — point it at managed databases (see the chart README)
• Data lineage visualization

AI Agent Integration

Datanika speaks MCP, so AI agents (Claude Desktop, Claude Code, Cursor, …) can browse connections, preview data, compile transformations, and monitor runs natively. 25 tools — 17 read-only, 8 write. There are two ways in.

Hosted — nothing to install. Paste this wherever your client accepts a remote MCP server and authorize in the browser:

https://app.datanika.io/mcp

OAuth 2.1, no API key to handle. Read-only unless you grant write at consent — a client that asks for nothing gets read-only, and a pasted API key stays read-only here even if its own scopes allow writes.

Local — stdio. Published on PyPI as datanika-mcp and listed on the official MCP registry as io.datanika/datanika-mcp:

# read-only by default; add --allow-write to enable the 8 write tools
uvx datanika-mcp --url https://app.datanika.io --api-key YOUR_KEY

See datanika-mcp/README.md for per-client config snippets and the full tool list, or datanika.io/docs/mcp-server for the hosted walkthrough.

Additional agent resources:

• /llms.txt — discovery document
• /api/v1/openapi.json — OpenAPI spec with typed inline schemas
• /api/v1/meta/agent-tiers — 5-tier capability stack (JSON)
• docs/api_versioning.md — stability tiers and deprecation policy

Open-Core Strategy

Core platform is open-source (AGPL-3.0). Cloud version adds billing, quotas, and usage metering via the datanika-cloud plugin.

Footnotes

1. Competitor connector counts as published by each vendor's own connector directory, checked 2026-08-30. Ours is derived from ConnectionType in code, not written by hand. We do not track other vendors' catalogues continuously — if this footnote's date looks old, check the source rather than trusting the number. ↩ ↩²
