Deasil operates the endpoint. The engine is txn2/mcp-data-platform, Apache-2.0. I wrote the harness this replaced.

Trino, S3, DataHub, and vendor APIs do not share an identity model. They all have a credential.

Pre-registered clients and PKCE. Login stays in the IdP.

Index the OpenAPI document. Search across catalogs. Then call one operation.

platform_info mints dps_…; the model threads it. Go SDK v1.7.0, MCP 2026-07-28.

Hive still maps a table name to a directory of files

starlark-go in a Go server: FileOptions, host bindings, and a cancel watchdog

Structural ratchets for AI-assisted Go, six months into make verify

The agent found every page certified unreachable. Links cut search cost and keep working when search is off; they do not change what it reaches

A wrong note that passed review spread only where the agent could have checked it, and only on Haiku 4.5: 16 of 24, against 0 of 24 on Sonnet 5 and Opus 5

Adding your own GPUs to the platform with the NVIDIA GPU Operator

A single Kubernetes cluster spanning cloud regions and your own hardware, encrypted over the public internet

Why the chapter is cut from this rebuild, and where tamper-evidence lives in 2026

Scale-to-zero functions you own, after OpenFaaS moved the good parts behind a paywall

Running Cassandra and Scylla on K8ssandra and the Scylla Operator after Rook dropped its own

Object storage that triggers work, a self-hosted answer to S3 plus Lambda on your own cluster

The harness behind two DOI-archived benchmark reports, and why a study premise can be killed in one working day

Self-hosted notebooks for the whole team, on Keycloak SSO, wired to the lakehouse and every data source you own

Lightweight device messaging into the platform, bridged to Kafka, with the Mosquitto 2.0 change the old guides miss

Self-hosted observability for everything you built, on the open standard instead of a per-host APM bill

A benchmark that killed its own hypothesis: strong models re-derive what they can check, and a weak model trusts a stale note over the evidence in front of it

The CNI that replaced Weave Net, kube-proxy, and a hand-rolled WireGuard overlay with a single component

The container runtime the kubelet actually uses, and how to configure and debug it now that the Docker shim is gone

A reproducible benchmark: 42.7% to 98.7% on knowledge-trap questions, and a platform that learns from empty

Argo CD and Flux, the deployment half the 2020 book left out, with manifests reconciled from a repo you own

Rootless container builds in CI with BuildKit, and where supply-chain guardrails belong

Self-hosted source, CI/CD, and a registry, on the lightweight fork that left its for-profit parent

An Apache-2.0 MCP server that gives frontier models access and grounded context to everything you built

Metadata, lineage, and a business glossary over the whole platform

Dashboards and SQL exploration over the lakehouse and Postgres, a Tableau replacement on the platform's SSO
