Public repositories on github.com/kapoost plus my contribution thread on the AdCP spec. Active threads first; the rest underneath.

In production AdCP TypeScript

purrsonality-seller-agent

Production-grade AdCP seller agent reference implementation. Bun + @adcp/sdk 7.11.0 + Postgres + Fly.io. Storyboard compliance baseline: 131 passed / 1 failed / 53 skipped against the current AdCP 3.1 RC runner.

Active Monorepo TypeScript

adcp-signals

Signal-owned agent monorepo for AdCP: pluggable core framework plus per-publisher catalog variants (vanilla, cats, more on the way). Reference for how a signal provider answers get_signals and activate_signal without leaking implementation noise.

Repo: github.com/kapoost/adcp-signals

Active Go Indie web

humanmcp-go

Personal MCP server. Publish poems, images and structured data with Ed25519 signatures so any AI agent can verify provenance offline. Session gate uses a fragment of Polish poetry as the access code. Deployed at kapoost.humanmcp.net.

Active Go

humanmcp-marketplace

Federated listings marketplace across personal humanMCP servers. One agentic discovery surface over many self-hosted endpoints; no central registry beyond what the participants themselves opt into.

Repo: github.com/kapoost/humanmcp-marketplace

Active Python RAG

mysloodsiewnia

Local RAG knowledge vault — index your PDFs, manuals and personal notes; query from AI agents through humanMCP. Designed to run on your laptop, not on a SaaS. The name is a portmanteau of myśl (thought) and odsiewnia (a sieve, a winnowing).

Lab pieces

★ 1 HTML Procedural audio

seestar-kiosk

Live telescope kiosk for the ZWO Seestar S30 Pro. Displays the current stacked frame and runs a procedural jazz engine driven by stacking telemetry — the music quite literally tracks what the telescope is seeing.

Active TypeScript PWA

logoped

Speech-therapy PWA for children and therapists. Polish-first interface, offline-capable, designed for shared use on a single tablet.

Repo: github.com/kapoost/logoped

Experiment JavaScript

humanmcp-rpg

Small experiment: treat a humanMCP endpoint as a game master. Personas become NPCs, content becomes lore, the session code becomes the door to the dungeon.

AdCP spec contributions

Small, targeted work on the upstream adcontextprotocol/adcp repository — issues that the storyboard runner missed, schema clarifications that close ambiguities, docs that document what implementations actually do.

Merged: #4918 — docs(accounts): clarify single-publisher cardinality on list_accounts.
Open: #4497 — brand.json: add structural category restrictions and jurisdiction fields.
Closed issues that drove fixes upstream: #5013 (check_publisher_authorization false negative), #4914 (pagination_integrity unsatisfiable for single-publisher sellers), #4832 (v3 envelope integrity vs SDK 7.7.0 drift), #4831 (security_baseline assert_mechanism for Bearer-only sellers), #4776 (adagents.json authorization_type underdocumented), #4775 (validate_agent stale-cache bug), #4196 (pending_creatives status-name ambiguity).

Everything else
