  "markdown": "# @pipeworx/reverb\n\nLive listings from Reverb.com, the musical-instrument marketplace — guitars,\namps, pedals, synths, drums and pro audio, with make/model/year/finish/condition\nand the seller's **asking price**.\n\nPart of [Pipeworx](https://pipeworx.io) — an MCP gateway connecting AI agents to 1558+ live data sources.\n\n## Tools\n\n- `reverb_search(query, ...)` — listing search with the gear filters (make,\n  model, product_type/category, condition, price band, year range, region,\n  handmade, sort/order). Answers \"what is a 1960s Gibson electric going for\n  right now, and who is selling it\".\n- `reverb_listing(listing_id)` — one listing in full: seller description,\n  asking and buyer price, offer/inventory state, photos, shipping rates by\n  region.\n- `reverb_shop(shop_slug)` — seller profile: feedback count, rating,\n  preferred-seller status, location, shipping posture.\n- `reverb_categories(root_slug?)` — the category tree, so a caller can fill\n  `product_type` / `category` on `reverb_search` without guessing slugs.\n\n## Auth\n\nKeyless. Every endpoint this pack calls answers without a token — verified\n2026-09-05. Only account-scoped Reverb endpoints (`/api/my/*`, orders, selling)\nneed OAuth, and none of those are exposed here, so there is no\n`PLATFORM_REVERB_KEY` and no BYOK path.\n\n## Asking prices only — there is no sold data here\n\nReverb's public Price Guide is **retired**. Both `/api/priceguide` and\n`/api/priceguide/transactions` answer:\n\n```\nHTTP 403  { \"Error\": \"This endpoint is no longer publicly available.\" }\n```\n\nfor every query (verified 2026-09-05). Everything this pack returns is a live\nasking price, not a realized sale, and every response says so in its\n`price_basis` and `sold_data` fields. Do not use it as comps. For realized\ninstrument prices, Reverb is not the source.\n\n## Data sources\n\n- <https://api.reverb.com/api/listings/all> — listing search. Params used:\n  `query, make, model, product_type, category, condition, price_min, price_max,\n  currency, year_min, year_max, item_region, ships_to, handmade, sort, order,\n  page, per_page`.\n- <https://api.reverb.com/api/listings/{id}> — listing detail.\n- <https://api.reverb.com/api/shops/{slug}> — seller profile.\n- <https://api.reverb.com/api/categories/flat> — the full category tree (roots plus sub-categories, 320 entries). Plain `/api/categories` returns only the 14 roots.\n\nDocs live at <https://www.reverb-api.com> (`dev.reverb.com` redirects there).\n\nThings worth not rediscovering:\n\n- The `Accept-Version: 3.0` and `Accept: application/hal+json` headers are what\n  select the JSON API. Without them you can get HTML.\n- **`total_pages` is capped at 50** regardless of `total` — a 77,081-result\n  query still reports `total_pages: 50`. Requesting `page=51` nevertheless\n  returns results, so treat the cap as a display artifact, not a paging bound.\n  `reverb_search` returns a `total_pages_note` saying this.\n- `price` and `buyer_price` differ when tax is involved; `listing_currency` is\n  the seller's currency, while `price.currency` follows the `currency` param.\n- Listing detail carries the shop's `feedback_count` and `rating_percentage`,\n  which the search payload omits.\n- `reverb.com/llms.txt` is a 404 as of 2026-09-05, despite reports otherwise.\n\n## Quick Start\n\nAdd to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"reverb\": {\n      \"url\": \"https://gateway.pipeworx.io/reverb/mcp\"\n    }\n  }\n}\n```\n\n### What this endpoint actually serves\n\n`tools/list` at `https://gateway.pipeworx.io/reverb/mcp` returns the tools in the table\nabove **plus the shared Pipeworx meta-tools** — `ask_pipeworx`,\n`discover_tools`, `search_within`, `remember`/`recall` and the rest of the\ngateway-wide set. So the tool count you see is larger than this table: a\nsingle-pack endpoint currently lists roughly 30 shared tools alongside the\npack's own. The connection's `initialize` response states its exact scope, and\nis the authoritative answer for a given day.\n\nThis is deliberate, not multiplexing by accident. The meta-tools are what let a\nscoped connection answer a question this pack does not cover — via\n`ask_pipeworx`, which routes across the whole catalog — without you adding a\nsecond MCP server. There is currently no way to mount a pack endpoint without\nthem; if the extra schemas cost you more context than the routing is worth,\nconnect to the full gateway once rather than to several pack endpoints.\n\nOr connect to the full Pipeworx gateway to get every pack's tools listed\ndirectly, instead of just this one's:\n\n```json\n{\n  \"mcpServers\": {\n    \"pipeworx\": {\n      \"url\": \"https://gateway.pipeworx.io/mcp\"\n    }\n  }\n}\n```\n\nBoth URLs reach the same gateway and the same 1558+ data sources. The\nonly difference is which pack's tools are listed **directly**; `ask_pipeworx`\nreaches all of them from either one.\n\n## Standalone (no gateway account)\n\nThis package also runs as a local stdio MCP server — no Pipeworx account, no\ngateway round-trip:\n\n```json\n{\n  \"mcpServers\": {\n    \"reverb\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@pipeworx/mcp-reverb\"]\n    }\n  }\n}\n```\n\nOr run it directly to confirm it starts:\n\n```bash\nnpx -y @pipeworx/mcp-reverb\n```\n\nIt speaks MCP over stdin/stdout and answers `initialize`/`tools/list`/`tools/call`\nfor **only** this pack's tools — none of the shared meta-tools the gateway\nconnection above adds. Same source, same tools, no ask_pipeworx routing.\n\n## Using with ask_pipeworx\n\nInstead of calling tools directly, you can ask questions in plain English —\nthis works on the pack endpoint above as well as on the full gateway:\n\n```\nask_pipeworx({ question: \"your question about Reverb data\" })\n```\n\nThe gateway picks the right tool and fills the arguments automatically.\n\n## More\n\n- [Docs and guides](https://pipeworx.io/docs)\n- [pipeworx.io](https://pipeworx.io)\n\n## License\n\nMIT\n",
