Gumroad — Printing Press CLI skill

Gumroad — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the gumroad-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install gumroad --cli-only
   

2. Verify: gumroad-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

go install github.com/mvanhorn/printing-press-library/library/commerce/gumroad/cmd/gumroad-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Use this skill when the user asks to inspect or operate a Gumroad seller account, especially products, sales, subscribers, payouts, licenses, offer codes, or tax data. Prefer sync/search/analytics for broad questions and direct endpoint commands for a specific object or mutation.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local seller intelligence

• sync --resources products,sales,subscribers,payouts --latest-only --json — Refresh a local SQLite snapshot of the seller-facing Gumroad resources that agents inspect most often.

  Use this before research or reporting tasks so later searches and analytics are grounded in one consistent seller snapshot.

  gumroad-pp-cli sync --resources products,sales,subscribers,payouts --latest-only --json
  

• search — Search locally synced products, sales, subscribers, payouts, and tax records through one command.

  Use this when the user remembers a buyer, product, license, or payout clue but not the exact Gumroad object ID.

  gumroad-pp-cli search "annual plan" --data-source local --json --limit 20
  

• analytics — Group and count synced Gumroad records locally for fast summaries without additional API traffic.

  Use this for lightweight revenue, subscriber, product, and payout triage after a sync.

  gumroad-pp-cli analytics --type sales --group-by product_id --limit 10 --json
  

Operational monitoring

• tail — Poll selected Gumroad resources and emit NDJSON changes for scripts or agent monitors.

  Use this for one-off checks after a launch, refund, payout, or product update.

  gumroad-pp-cli tail --resource sales --interval 30s --json

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

gumroad-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

List live products

gumroad-pp-cli products list --agent

Returns compact JSON for the authenticated seller's products.

Find a buyer or license locally

gumroad-pp-cli search "customer query" --data-source local --json

Searches previously synced seller data without making additional API calls.

Review payout history

gumroad-pp-cli payouts list --after 2026-01-01 --agent

Reads payout records with pagination metadata when the token has view_payouts scope.

Auth Setup

Create a Gumroad OAuth application, authorize it with the scopes needed for your workflow, and provide the resulting access token as GUMROAD_ACCESS_TOKEN. The MCP bundle exposes this as a sensitive user configuration value.

Run gumroad-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  gumroad-pp-cli earnings --year 42 --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Explicit retries — use --idempotent only when an already-existing create should count as success, and --ignore-missing only when a missing delete target should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

gumroad-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
gumroad-pp-cli feedback --stdin < notes.txt
gumroad-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.gumroad-pp-cli/feedback.jsonl. They are never POSTed unless GUMROAD_FEEDBACK_ENDPOINT is set AND either --send is passed or GUMROAD_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Sink	Effect
stdout	Default; write to stdout only
file:<path>	Atomically write output to <path> (tmp + rename)
webhook:<url>	POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

gumroad-pp-cli profile save briefing --json
gumroad-pp-cli --profile briefing earnings --year 42
gumroad-pp-cli profile list --json
gumroad-pp-cli profile show briefing
gumroad-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Code	Meaning
0	Success
2	Usage error (wrong arguments)
3	Resource not found
4	Authentication required
5	API error (upstream issue)
7	Rate limited (wait and retry)
10	Config error

Argument Parsing

Parse $ARGUMENTS:

1. Empty, help, or --help → show gumroad-pp-cli --help output
2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

claude mcp add gumroad-pp-mcp -- gumroad-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which gumroad-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
3. Execute with the --agent flag:

   gumroad-pp-cli <command> [subcommand] [args] --agent
   

4. If ambiguous, drill into subcommand help: gumroad-pp-cli <command> --help.
