Every Discogs feature — plus a local price-history mirror the API doesn't keep, so you can watch your wantlist like a limit-order book, spot underpriced records, and track your collection's value over time.
A single Go binary over the full Discogs API — database, collection, wantlist, and marketplace — with an offline SQLite mirror and an MCP server. Because Discogs keeps no price history, this CLI snapshots prices locally, which unlocks fills (wantlist limit orders), undervalued detection, portfolio value over time, and condition-matched comps that no other Discogs tool offers.
Authentication
Database search and lookups are public. Everything tied to a user — collection, wantlist, marketplace, identity — needs a free personal access token from discogs.com/settings/developers, set as DISCOGS_TOKEN. The client sends it as Authorization: Discogs token=<token> and always sends a descriptive User-Agent (Discogs returns 403 without one).
Quick Start
# Confirm config and reachability before anything else.
discogs-pp-cli doctor --dry-run
# Public database search — works without a token.
discogs-pp-cli database search "nevermind" --artist Nirvana --format Vinyl
# Confirm your DISCOGS_TOKEN resolves to your account.
discogs-pp-cli identity whoami
# Populate the local mirror so offline and price features work.
discogs-pp-cli sync --resources wantlist,collection
# The flagship: wantlist items now selling at or below your limit.
discogs-pp-cli fills --agent
Unique Features
These capabilities aren't available in any other tool for this API.
Local price history (the moat)
-
fills — Treat each wantlist entry as a standing limit order and surface the ones now selling at or below the max price you set.
Reach for this to answer 'which of my wants are buyable right now' without checking hundreds of listings by hand under the 60/min limit.
discogs-pp-cli fills --agent
-
portfolio — Chart your collection's value over time with per-record contribution to the change and cost-basis P&L.
Use it when the question is 'is my collection up or down, and because of what' rather than 'what is it worth today'.
discogs-pp-cli portfolio --since 90d --agent
-
undervalued — Flag releases whose current asking price sits below their own trailing/suggested baseline.
Pick this for market-wide mispricing where no preset limit exists; use 'fills' when the trigger is a limit you set.
discogs-pp-cli undervalued --scope wantlist --agent
-
comps — The condition-by-condition price picture for one release, with local snapshot history the API can't provide.
Use it to price or value a single specific release; use 'pressings' to compare different versions of the same album.
discogs-pp-cli comps 249504 --agent
-
pressings — Rank all versions/pressings of a master release by value and liquidity so you know which pressing to buy, want, or sell.
Use it to choose among pressings of an album; use 'comps' for the condition breakdown of one specific pressing.
discogs-pp-cli pressings 96559 --agent
Collector decisioning
-
sell-plan — Rank your inventory or collection by net-after-fee proceeds and liquidity so you know what to sell now.
Reach for this to decide what to list this week; use 'comps' to price one release.
discogs-pp-cli sell-plan --source collection --agent
-
identify — Resolve a physical record's catalog number or barcode to the exact release and show if you own it, want it, and what it's worth.
Use it crate-digging in a shop to make a buy/skip call fast; use 'search' for open-ended text queries.
discogs-pp-cli identify --barcode 0720642442524 --agent
Recipes
Deals on your wantlist
discogs-pp-cli fills --agent
Lists wantlist items whose lowest marketplace asking has reached the max price you set, with the change since last check.
Narrow a verbose release payload
discogs-pp-cli database release 249504 --agent --select id,title,year,labels.name,formats.descriptions,lowest_price
A Discogs release is tens of KB; dotted --select paths return only the fields you need so an agent doesn't burn context.
What to sell this week
discogs-pp-cli sell-plan --source collection --agent
Ranks your records by net-after-fee proceeds and liquidity.
Identify a record in-hand
discogs-pp-cli identify --barcode 0720642442524 --agent
Resolves the barcode to a release and tells you if you own it, want it, and its current value.
Value trend over the last quarter
discogs-pp-cli portfolio --since 90d --agent
Charts collection value change and the records that drove it, against cost basis.
Usage
Run discogs-pp-cli --help for the full command reference and flag list.
Paths & environment variables
This CLI separates local files into four path kinds:
| Kind | Contents |
|---|
config | User-editable settings such as config.toml and saved profiles |
data | Durable local data: credentials.toml, data.db, cookies, browser-session proof files, and other auth sidecars |
state | Runtime state such as persisted queries, jobs, and teach.log |
cache | Regenerable HTTP/cache files |
Each kind resolves independently. The ladder is:
- Per-kind env var:
DISCOGS_CONFIG_DIR, DISCOGS_DATA_DIR, DISCOGS_STATE_DIR, or DISCOGS_CACHE_DIR
--home <dir> for this invocationDISCOGS_HOME for a flat relocated root- XDG env vars:
XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME
- Platform defaults matching existing installs
For containers and agent sandboxes, prefer a single relocated root:
export DISCOGS_HOME=/srv/discogs
discogs-pp-cli doctor
Under DISCOGS_HOME=/srv/discogs, the four dirs resolve to /srv/discogs/config, /srv/discogs/data, /srv/discogs/state, and /srv/discogs/cache.
MCP servers do not receive CLI flags from the host. Put relocation in the host env block:
{
"mcpServers": {
"discogs": {
"command": "discogs-pp-mcp",
"env": {
"DISCOGS_HOME": "/srv/discogs"
}
}
}
}
Precedence matters in fleets: an ambient per-kind variable such as DISCOGS_DATA_DIR overrides an explicit --home for that kind. Use DISCOGS_HOME or the per-kind variables for durable fleet relocation; treat --home as the weaker per-invocation lever.
Relocation is one-way. Unsetting DISCOGS_HOME does not move files back to platform defaults, and doctor cannot find credentials left under a former root. Move the files manually before unsetting relocation variables.
Existing installs keep working because the platform-default rung matches the legacy layout. On the first auth write, stored secrets leave config.toml and are consolidated into credentials.toml under the data directory. Run discogs-pp-cli doctor --fail-on warn to check path and credential-location warnings in automation.

Self-learning loop
This CLI caches per-question discovery so repeat queries skip the walk and structurally similar queries get answered via entity substitution. The loop also self-captures: every invocation is journaled locally, and failed-flag corrections plus fresh teaches surface as candidates on the next recall for confirm/reject judgment. Agents call recall before discovery and fire teach & after answering. See the ## Automatic learning section in SKILL.md for the full protocol.
discogs-pp-cli recall <query> - Look up cached resources for a query before running discoverydiscogs-pp-cli teach - Record a query -> resource mapping (silent on success, safe to background with &)discogs-pp-cli learnings list - Inspect taught rowsdiscogs-pp-cli learnings forget <query> - Undo a teachdiscogs-pp-cli learnings candidates - List auto-captured candidates awaiting confirm/rejectdiscogs-pp-cli learnings stats - Local loop metrics: recall hit rate, teach-to-reuse, playbook resolution, candidate countsdiscogs-pp-cli teach-pattern - Install a query/resource template up frontdiscogs-pp-cli teach-lookup - Add an entity mapping (e.g. country code, team alias) for pattern substitution
Pass --no-learn or set DISCOGS_NO_LEARN=true to disable the loop for deterministic flows.
The local store's schema version stamp is one-way: once this version of discogs-pp-cli opens the database, older binaries refuse it with a version error — upgrade the binary rather than downgrading.

Agent Usage
This CLI is designed for AI agent consumption:
- Non-interactive - never prompts, every input is a flag
- Pipeable -
--json output to stdout, errors to stderr
- Filterable -
--select id,name returns only fields you need
- Previewable -
--dry-run shows the request without sending
- Explicit retries - add
--idempotent to create retries and add --ignore-missing to delete retries when a no-op success is acceptable
- Confirmable -
--yes for explicit confirmation of destructive actions
- Piped input - write commands can accept structured input when their help lists
--stdin
- Offline-friendly - sync/search commands can use the local SQLite store when available
- Agent-safe by default - no colors or formatting unless
--human-friendly is set
Exit codes: 0 success, 2 usage error, 3 not found, 4 auth error, 5 API error, 7 rate limited, 10 config error.
Health Check
discogs-pp-cli doctor
Verifies configuration, credentials, and connectivity to the API.
Configuration
Run discogs-pp-cli doctor to see the resolved config, data, state, and cache directories. The platform-default config path is ~/.config/discogs-pp-cli/config.toml; --home, DISCOGS_HOME, and per-kind env vars can relocate it.
Static request headers can be configured under headers; per-command header overrides take precedence.
Environment variables:
| Name | Kind | Required | Description |
|---|
DISCOGS_TOKEN | per_call | Yes | Set to your API credential. |
agentcookie (optional)
If you use agentcookie to sync secrets across machines, this CLI auto-adopts agentcookie-managed credentials with no extra setup. When the daemon writes to this CLI's config, discogs-pp-cli doctor reports agentcookie: detected and auth-status labels the source as agentcookie. Skip this section if you don't use agentcookie - the CLI works the same as any other.
Troubleshooting
Authentication errors (exit code 4)
- Run
discogs-pp-cli doctor to check credentials
- Verify the environment variable is set:
echo $DISCOGS_TOKEN
Not found errors (exit code 3)
- Check the resource ID is correct
- Run the
list command to see available items
API-specific
- 403 Forbidden on every request — Discogs requires a descriptive User-Agent; the CLI sends one automatically — rebuild if you see this.
- 429 / rate limited — Discogs allows 60 req/min authenticated. Run
sync and use offline commands; the client backs off on the X-Discogs-Ratelimit-Remaining header.
- 401 Unauthorized on collection/wantlist/marketplace — Set DISCOGS_TOKEN (free token at discogs.com/settings/developers). Database search works without one.
- fills or undervalued returns nothing — Run
sync first and let a few price snapshots accumulate; these features read local price history.
