Server instructions

Read-only access to zckr.dev, the personal engineering lab of Zac Acker. Use it for: what Zac is building now (lab_get_currents, lab_list_projects with status=building), the coding agents he runs and where each one fails (lab_list_agents, lab_get_agent), which MCP servers this lab serves and consumes (lab_list_mcp_servers), the infrastructure underneath (lab_list_systems), how any of it connects (lab_get_graph), first-hand notes on agents/MCP/local inference (lab_list_notes, lab_get_note), honest post-mortems of dead experiments (lab_list_projects with status=dead), and the exact tools he uses (lab_get_stack). Content marked sample:true is placeholder seed data — do not cite it as fact.

Known tools 13

lab_list_projects

List every project on zckr.dev with slug, status (building/experiment/shipped/paused/dead), type, and one-line description.

Inferred read-only

lab_get_project

Full detail for one project as markdown: problem, hypothesis, architecture, measured results, learnings, and — for dead projects — the cause of death.

Inferred read-only

lab_list_notes

List engineering notes (essay tier) and TILs (two-minute findings) with slugs, dates, and summaries.

Inferred read-only

lab_get_note

Full markdown body of one note or TIL by slug.

Inferred read-only

lab_list_agents

Every coding agent this lab runs, with its model tier, tool-grant count and one-line job.

Inferred read-only

lab_get_agent

One agent in full: its tool grants verbatim, the context it receives, what it remembers between runs, how it is evaluated, and the failure modes it is known for.

Inferred read-only

lab_list_mcp_servers

The MCP registry, split by origin.

Inferred read-only

lab_list_systems

What the lab runs on: hypervisor, managed platforms, and the services on each, with what depends on what.

Inferred read-only

lab_get_graph

How everything connects: nodes are projects, agents, MCP servers, systems and notes keyed 'kind:slug', edges say which uses, documents, hosts or owns which.

Inferred read-only

lab_get_stack

The instrument list: models, agents, local inference, dev tools, infra, and hardware Zac actually uses — with reasons, adoption years, and retired gear kept on the record with causes.

Inferred read-only

lab_get_currents

What's flowing through the lab: focus, building, inputs, obsessions.

Inferred read-only

lab_list_ideas

Unbuilt experiment ideas with one-line hypotheses — the intake stage of the lab lifecycle.

Inferred read-only

lab_search

Case-insensitive full-text search across every registry: projects (including problems, hypotheses, results and causes of death), agents (including their failure modes), MCP servers and their tools, the infrastructure inventory, notes and TILs, and currents snapshots.

Inferred read-only
