Pad Core

For-agent markdown store — MCP-first. Agents create / read / update markdown docs (and threaded, anchored comments) over MCP; storage is Postgres. No human web UI — agents are the only consumers.

Layout (turborepo + bun)

• packages/domain — @workspace/domain: drizzle schema, authz (single source), ops, migrations
• apps/mcp — pad-core: Bun MCP server (/mcp, bearer-gated, owner-scoped)

Dev

bun install
bun run typecheck
# needs DATABASE_URL, MCP_WRITE_TOKEN (>=16 chars), OWNER_EMAIL
bun run apps/mcp/src/server.ts

MCP tools

doc_create · doc_read · doc_update (optimistic lock via base_version) · doc_list · comments_list · comment_reply · comment_resolve

Deploy

CI builds ghcr.io/zyx1121/pad-core (SHA-pinned) → deployed to k3s via the vivarium GitOps repo (namespace pad): pad-db (Postgres) + pad-core. MCP endpoint: pad-mcp.app.zyx.tw (external, token) · pad-mcp.internal (in-cluster).

A human read/comment web app (apps/web + packages/ui) was removed — it lives in git history if ever needed, but agents talk to pad over MCP, not a browser.
