datanika-mcp MCP Server

Read-only-by-default MCP for Datanika: browse data, run dbt transforms, manage ELT pipelines.

Publisher claimed. No tool list reported, and Pod has not connected to this server.

Status

Pod has not dialled datanika-mcp yet, so everything on this page is what its publisher reported rather than what we observed. Registries describe servers; they do not connect to them. Until a check runs, treat the tool list below as a claim.

Connect

Published as datanika-mcp on pypi. Runs locally.

Known issues

31 problems reported by people outside the maintainer team. Issues filed by the project's own owners, members and collaborators are excluded — those are release checklists and internal refactors, not things that will go wrong for you. Showing 12.

Most discussed

[Engineering] P0: mcp 2.x breaks the image — datanika-mcp's unpinned dep clobbers core's mcp<2, /mcp unmounted, all deploys blocked

This blocks every production deploy. Found when a monitoring-only promotion (#601) failed on the box. Nothing about that change was related; any deploy today would have hit this.

Symptom

deploy-pointer.yml → Deploy the app via blue/green swap fails its post-swap assertion:

15:59:08   public /mcp unauth -> 404 (expect 401; 200 means it fell through to the SPA)
15:59:08 FATAL: /mcp returned 404

The app itself is healthy — /healthz, /readyz, / all 200 on the new colou

[QA] S1: prod runs 4 Reflex workers with per-process state — 48% of reconnects are served a stale session (root cause of #472/#529)

S1 — reproduced on production, 2026-08-30, without a browser.

Production runs the Reflex backend as 4 independent worker processes with a per-process state store. A client that reconnects lands on a different process roughly half the time and is served a state that has lost earlier writes. Since AuthState.access_token is a plain server-side state var and check_auth does if not self.access_token: return rx.redirect("/login"), a stale read is a logout.

This is the cause of

[Growth] List datanika-mcp in the MCP registries (discoverability)

Part of the AI-first agent-surface wave (coordinator-routed 2026-07-18). Quick win — free discoverability where agents/users browse for tools.

Gap: we have a working MCP server but it's unlisted, so nobody browsing MCP directories finds Datanika.

Scope (registry landscape verified 2026-07-18)

Publish to the official MCP registry first — registry.modelcontextprotocol.io (Anthropic/GitHub/Microsoft/PulseMCP metaregistry). It feeds the directories + clients, so do it first

[Infra P0] Post-deploy smoke gate — app.datanika.io after ci.yml

Summary

Add a post-deploy smoke gate as a new job in .github/workflows/ci.yml that runs after the Deploy step on push to master, curls a curated list of URLs on https://app.datanika.io, asserts 200 + non-empty body (plus per-URL content-type and body-substring checks), and fails the workflow on any miss. Same task in parallel on the landing side: datanika-landing (separate tracking issue, same source-of-truth).

Paired issue: datanika-landing#<TBD, see cross-ref> adds the

datanika-mcp: the transport's stateless mode and its private-attribute reach-through both need guards

Filed by Infra while deciding the mcp 2.x question left open by #602. Nothing is broken and nothing is exploitable today — this is about two invariants that currently hold by accident.

1. `stateless=True` is load-bearing, and nothing says so

datanika-mcp/src/datanika_mcp/server.py:492-496:

manager = StreamableHTTPSessionManager(
