Facebook Marketplace — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the facebook-marketplace-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 facebook-marketplace --cli-only

2. Verify: facebook-marketplace-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 1.26.4 or newer):

go install github.com/mvanhorn/printing-press-library/library/commerce/facebook-marketplace/cmd/facebook-marketplace-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 CLI for local, human-paced Facebook Marketplace workflows: searching, watching, triaging matches, drafting listings, and replying to seller inbox threads after explicit approval. Avoid using it for bulk automation or cross-platform scraping.

Unique Capabilities

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

Seller workflow

• `draft` — Draft a Marketplace title, description, and price suggestion from photos and notes.

_Use this when preparing a seller listing before opening a write-gated post flow._

  facebook-marketplace-pp-cli draft --photos chair-front.jpg,chair-tag.jpg --notes "walnut dining chair, small scratch on back" --json

• `reply` — Prepare and send a seller inbox reply only when --write and doctor gating both pass.

_Use this only for human-approved sell-side messaging._

  facebook-marketplace-pp-cli reply --thread 1525836598898750 --message "Yes, it is still available." --write --json

Buy-side workflow

• `watch add` — Persist a Marketplace search watch with deterministic keyword, price, and distance filters.

_Use this when the agent needs to monitor Marketplace without deciding relevance on every raw result._

  facebook-marketplace-pp-cli watch add --name "eames" --query "eames lounge" --max-price 1500 --radius 60 --must-have-keywords "chair,lounge" --json

• `matches` — Show new watch matches after deterministic filtering.

_Use this when an agent needs the shortlist worth showing a human buyer._

  facebook-marketplace-pp-cli matches --new --json

Local mirror

• `stale` — Find local seller listings older than seven days with no engagement.

_Use this when deciding which seller listings need price changes or renewal._

  facebook-marketplace-pp-cli stale --days 7 --json

HTTP Transport

This CLI uses Chrome-compatible HTTP transport over HTTP/3 for browser-facing endpoints. It does not require a resident browser process for normal API calls.

Finding the right command

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

facebook-marketplace-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

Create a buy-side watch

facebook-marketplace-pp-cli watch add --name "eames" --query "eames lounge" --max-price 1500 --radius 60 --json

Stores deterministic filter criteria locally so future runs can compare new listings.

Draft a seller listing

facebook-marketplace-pp-cli draft --photos chair-front.jpg,chair-tag.jpg --notes "walnut dining chair, small scratch" --json

Produces listing copy before any write-gated Marketplace mutation.

To create with local photos, run facebook-marketplace-pp-cli doctor first, then pass --write and one or more --photo flags to listing create. The CLI uploads each local file, appends the returned photo_id values to variables.input.data.common.photo_ids, and then submits the create mutation.

Auth Setup

Run facebook-marketplace-pp-cli auth login --chrome while logged in to Facebook in Chrome. The captured browser session is the credential; do not store session material in the Dropbox project workspace.

Run facebook-marketplace-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:

  facebook-marketplace-pp-cli inbox list --fb-api-req-friendly-name example-resource --agent --select id,name,status

• Previewable — --dry-run shows the request without sending
• Non-interactive — never prompts, every input is a flag
• Explicit retries — use --idempotent only when an already-existing create should count as success

Agent Feedback

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

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

Entries are stored locally at ~/.facebook-marketplace-pp-cli/feedback.jsonl. They are never POSTed unless FACEBOOK_MARKET_FEEDBACK_ENDPOINT is set AND either --send is passed or FACEBOOK_MARKET_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:

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.

facebook-marketplace-pp-cli profile save briefing --json
facebook-marketplace-pp-cli --profile briefing inbox list --fb-api-req-friendly-name example-resource
facebook-marketplace-pp-cli profile list --json
facebook-marketplace-pp-cli profile show briefing
facebook-marketplace-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

Argument Parsing

Parse $ARGUMENTS:

1. Empty, `help`, or `--help` → show facebook-marketplace-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 facebook-marketplace-pp-mcp -- facebook-marketplace-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which facebook-marketplace-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:

   facebook-marketplace-pp-cli <command> [subcommand] [args] --agent

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