# unsplash-mcp-server [](https://www.npmjs.com/package/@hanoak/unsplash-mcp-server) [](https://www.npmjs.com/package/@hanoak/unsplash-mcp-server) [](https://github.com/hanoak/unsplash-mcp-server/actions/workflows/ci.yml) [](./LICENSE) [](#requirements) [](./CONTRIBUTING.md) A production-ready [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server for the [Unsplash API](https://unsplash.com/developers). It gives AI assistants — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and any MCP client — tools to search and fetch Unsplash photos, collections, topics, users, and stats, with **Unsplash-guideline compliance built in** (ready-to-use attribution and download tracking). > [!IMPORTANT] > **Unofficial project.** This is not affiliated with, endorsed by, or sponsored by Unsplash. "Unsplash" is a trademark of its respective owner. You use it under your own Unsplash API account and are responsible for complying with the [Unsplash API Terms & Guidelines](https://help.unsplash.com/en/articles/2511245-unsplash-api-guidelines). ## Table of contents - [Features](#features) - [Quick start](#quick-start) - [Example interaction](#example-interaction) - [Configuration](#configuration) - [Tools](#tools) - [Tool reference](#tool-reference) - [Output shape](#output-shape) - [Resources & prompts](#resources--prompts) - [Example prompts](#example-prompts) - [Attribution & compliance](#attribution--compliance) - [Rate limits](#rate-limits) - [Handling of Unsplash text](#handling-of-unsplash-text) - [Privacy & security](#privacy--security) - [Troubleshooting](#troubleshooting) - [FAQ](#faq) - [Requirements](#requirements) - [Compatibility](#compatibility) - [Roadmap](#roadmap) - [Contributing](#contributing) - [Contact & community](#contact--community) - [License](#license) ## Features - **21 tools** across photos, search, users, collections, topics, and stats. - **Compliance built in** — every photo comes with ready-to-use attribution (plain text + UTM-tagged HTML), and a dedicated `unsplash_track_download` tool for the download-tracking guideline. - **Content safety** — `content_filter=high` by default on search and random photos. - **Flexible image URLs** — each photo returns `raw`/`full`/`regular`/`small`/`thumb` sizes, plus a `raw` imgix base for custom sizes (`?w=&h=&q=&fm=&fit=`). - **Token-efficient output** — full Unsplash responses are trimmed to a compact shape (URLs + metadata as text, never base64 image blobs) to keep model context small. - **Robust** — typed failures returned as MCP `isError` results the model can recover from, plus retries/backoff, timeouts, `403` hourly-limit handling, and rate-limit surfacing. - **Safe** — access-key redaction in all error output, an SSRF guard on download URLs, and untrusted-text handling guidance for indirect prompt-injection defence. - **Lean & modern** — ESM, Node 20+, zero-install via `npx`, no telemetry. ## Quick start ### 1. Get an Unsplash access key Register an application at **[unsplash.com/developers](https://unsplash.com/developers)** → **New Application** → accept the API terms → copy its **Access Key** (not the Secret Key). New apps start on the **Demo** tier (50 requests/hour); the **Production** tier (5,000/hour) requires Unsplash's review from your app dashboard. See [Rate limits](#rate-limits). ### 2. Add the server to your MCP client **Claude Desktop** — edit `claude_desktop_config.json`: - macOS: `~/Library/Application Support/Claude/claude_desktop_config.json` - Windows: `%APPDATA%\Claude\claude_desktop_config.json` ```json { "mcpServers": { "unsplash": { "command": "npx", "args": ["-y", "@hanoak/unsplash-mcp-server"], "env": { "UNSPLASH_ACCESS_KEY": "your_access_key", "UNSPLASH_APP_NAME": "your_registered_app_name" } } } } ``` Restart the client. See [Configuration](#configuration) for every supported variable. <details> <summary><b>Other clients (Claude Code, Cursor, VS Code, Windsurf, generic stdio)</b></summary> **Claude Code** (CLI): ```bash claude mcp add unsplash \ --env UNSPLASH_ACCESS_KEY=your_access_key \ --env UNSPLASH_APP_NAME=your_registered_app_name \ -- npx -y @hanoak/unsplash-mcp-server ``` **Cursor** — `~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (per-project): use the exact same `mcpServers` block as Claude Desktop above. **Windsurf** — `~/.codeium/windsurf/mcp_config.json`: same `mcpServers` block as Claude Desktop above. **VS Code** — `.vscode/mcp.json` (note the top-level key is `servers`, not `mcpServers`): ```json { "servers": { "unsplash": { "command": "npx", "args": ["-y", "@hanoak/unsplash-mcp-server"], "env": { "UNSPLASH_ACCESS_KEY": "your_access_key", "UNSPLASH_APP_NAME": "your_registered_app_name" } } } } ``` **Any other MCP client** — run the server over **stdio** with: ```bash UNSPLASH_ACCESS_KEY=your_access_key npx -y @hanoak/unsplash-mcp-server ``` Point your client's stdio transport at `command: npx`, `args: ["-y", "@hanoak/unsplash-mcp-server"]`, and pass the key via `env`. </details> ### 3. Try it Restart your client and ask: > _"Find me a photo of mountains on Unsplash and show the attribution."_ ## Example interaction A typical flow: the model calls `unsplash_search_photos`, picks a result, presents the image with its attribution, and calls `unsplash_track_download` when it actually uses the photo. > **You:** Find a landscape photo of a foggy pine forest and credit the photographer. > > **Assistant:** _(calls `unsplash_search_photos` with `query: "foggy pine forest"`, `orientation: "landscape"`, picks the best result, then calls `unsplash_track_download` with its `download_location`)_ > Here's a great match — _Photo by Jane Doe on Unsplash_ — along with a ready-to-embed credit line and the image URL. Each tool returns a compact JSON payload. Here's the shape of a single photo result (illustrative values): <details> <summary><b>Example tool output</b></summary> ```json { "photo": { "id": "Dwu85P9SOIk", "description": "brown rocky mountain under blue sky during daytime", "width": 6000, "height": 4000, "color": "#734940", "blur_hash": "L6Pj0^i_.AyE_3t7t7R**0o#DgR4", "urls": { "raw": "https://images.unsplash.com/photo-1465…?ixid=…", "full": "https://images.unsplash.com/photo-1465…?ixid=…&q=85", "regular": "https://images.unsplash.com/photo-1465…?ixid=…&w=1080", "small": "https://images.unsplash.com/photo-1465…?ixid=…&w=400", "thumb": "https://images.unsplash.com/photo-1465…?ixid=…&w=200" }, "photo_page": "https://unsplash.com/photos/Dwu85P9SOIk", "download_location": "https://api.unsplash.com/photos/Dwu85P9SOIk/download?ixid=…", "photographer": { "name": "Jane Doe", "username": "janedoe", "profile": "https://unsplash.com/@janedoe" }, "attribution": { "text": "Photo by Jane Doe on Unsplash", "html": "Photo by <a href=\"https://unsplash.com/@janedoe?utm_source=your_app&utm_medium=referral\">Jane Doe</a> on <a href=\"https://unsplash.com/?utm_source=your_app&utm_medium=referral\">Unsplash</a>", "photographerName": "Jane Doe", "photographerUrl": "https://unsplash.com/@janedoe?utm_source=your_app&utm_medium=referral", "unsplashUrl": "https://unsplash.com/?utm_source=your_app&utm_medium=referral" } }, "rate_limit": { "limit": 50, "remaining": 49 } } ``` Every tool result includes a `rate_limit` object (`limit`, `remaining`) read from the Unsplash response headers. List/search tools wrap results in `photos`/`collections`/`users`/`topics` arrays with pagination fields (`total`, `total_pages`, `count`, `page`, `per_page`). </details> ## Configuration Configuration is entirely via environment variables — no config files, no flags for secrets. | Environment variable | Required | Description | | --------------------- | --------------- | --------------------------------------------------------------------------------------------------------------------------------------- | | `UNSPLASH_ACCESS_KEY` | **yes** | Your Unsplash API access key. The server exits at startup with a clear message if it is missing or blank. | | `UNSPLASH_APP_NAME` | **recommended** | Your registered Unsplash app name, used as the attribution `utm_source`. Defaults to a generic value (with a startup warning) if unset. | | `LOG_LEVEL` | no | `debug` \| `info` \| `warn` \| `error` (default `info`). All logs go to **stderr**; stdout carries only the MCP protocol. | CLI flags: `--version` and `--help` are supported (e.g. `npx @hanoak/unsplash-mcp-server --version`). ## Tools All tools are namespaced `unsplash_*` and are **read-only** (annotated `readOnlyHint: true`) except `unsplash_track_download`, which registers a download event and so is marked non-read-only. Parameters map to the Unsplash API; `per_page` and stats `quantity` are clamped to a max of **30**, and `page` is 1-based. | Domain | Tools | | --------------- | -------------------------------------------------------------------------------- | | **Photos** | `random_photo`, `list_photos`, `get_photo`, `photo_statistics`, `track_download` | | **Search** | `search_photos`, `search_collections`, `search_users` | | **Users** | `get_user`, `user_photos`, `user_collections`, `user_statistics` | | **Collections** | `list_collections`, `get_collection`, `collection_photos`, `related_collections` | | **Topics** | `list_topics`, `get_topic`, `topic_photos` | | **Stats** | `total_stats`, `month_stats` | > Writing to Unsplash (creating/updating collections, likes, editing your profile) requires the OAuth authorization-code flow and is planned for a future release — see [Roadmap](#roadmap). ### Tool reference <details> <summary><b>Photos</b></summary> | Tool | Parameters | Description | | --------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------- | | `unsplash_random_photo` | `query?`, `orientation?` (`landscape`\|`portrait`\|`squarish`), `content_filter?` (`low`\|`high`, default `high`), `collections?`, `topics?`, `username?` | A single random photo, optionally filtered. | | `unsplash_list_photos` | `page?` (default 1), `per_page?` (default 10, max 30) | The latest featured photos, paginated. | | `unsplash_get_photo` | `id` **(required)** | A single photo by ID or slug, full detail. | | `unsplash_photo_statistics` | `id` **(required)**, `quantity?` (days, default 30, max 30) | Download/view totals for a photo over N days. | | `unsplash_track_download` | `download_location` **(required)** — the `download_location` URL from a prior photo result (must be an `https://api.unsplash.com` URL) | Registers a download on real use; returns a fresh, usable download URL. | </details> <details> <summary><b>Search</b></summary> | Tool | Parameters | Description | | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------- | | `unsplash_search_photos` | `query` **(required)**, `page?`, `per_page?`, `order_by?` (`latest`\|`editorial`\|`relevant`), `orientation?`, `color?` (11 named colors, e.g. `blue`), `content_filter?` (default `high`), `collections?`, `lang?` | Keyword photo search with rich filters. | | `unsplash_search_collections` | `query` **(required)**, `page?`, `per_page?` | Keyword collection search. | | `unsplash_search_users` | `query` **(required)**, `page?`, `per_page?` | Keyword user search. | </details> <details> <summary><b>Users</b></summary> | Tool | Parameters | Description | | --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------ | | `unsplash_get_user` | `username` **(required)** | A user's public profile. | | `unsplash_user_photos` | `username` **(required)**, `page?`, `per_page?`, `order_by?` (`latest`\|`oldest`\|`popular`\|`views`\|`downloads`), `orientation?` | A user's photos, paginated. | | `unsplash_user_collections` | `username` **(required)**, `page?`, `per_page?` | A user's collections, paginated. | | `unsplash_user_statistics` | `username` **(required)**, `quantity?` (days, default 30, max 30) | A user's download/view totals over N days. | </details> <details> <summary><b>Collections</b></summary> | Tool | Parameters | Description | | ------------------------------ | --------------------------------------------------------- | -------------------------------------- | | `unsplash_list_collections` | `page?`, `per_page?` | The latest featured collections. | | `unsplash_get_collection` | `id` **(required)** | A single collection by ID. | | `unsplash_collection_photos` | `id` **(required)**, `page?`, `per_page?`, `orientation?` | Photos within a collection, paginated. | | `unsplash_related_collections` | `id` **(required)** | Collections related to a given one. | </details> <details> <summary><b>Topics & stats</b></summary> | Tool | Parameters | Description | | ----------------------- | -------------------------------------------------------------------------------------------------------- | -------------------------------------------- | | `unsplash_list_topics` | `page?`, `per_page?`, `order_by?` (`featured`\|`latest`\|`oldest`\|`position`), `ids?` (comma-separated) | Curated topics, paginated. | | `unsplash_get_topic` | `id` **(required)** — ID or slug (e.g. `nature`, `wallpapers`) | A single topic. | | `unsplash_topic_photos` | `id` **(required)**, `page?`, `per_page?`, `orientation?`, `order_by?` (`latest`\|`oldest`\|`popular`) | Photos within a topic, paginated. | | `unsplash_total_stats` | _(none)_ | Unsplash-wide totals (photos, downloads, …). | | `unsplash_month_stats` | _(none)_ | Unsplash-wide totals for the past 30 days. | </details> ### Output shape Tools return trimmed, token-efficient JSON rather than raw Unsplash responses: - **Photos** → `id`, `description`, `width`/`height`, `color`, `blur_hash`, `urls` (`raw`/`full`/`regular`/`small`/`thumb`), `photo_page`, `download_location`, `photographer`, and a ready-to-use `attribution` object. See [Example interaction](#example-interaction). - **Users** → `id`, `username`, `name`, `bio`, `location`, `profile_url`, `profile_image`, `total_photos`, `total_collections`. - **Collections / Topics** → title, description, counts, page link, curator/owners, and a compact `cover_photo`. - Every result carries a `rate_limit` (`limit`, `remaining`); lists/searches add pagination fields. ### Resources & prompts Beyond tools, the server also exposes: - **Resource** `unsplash://guides/attribution` — a compact compliance guide (attribution, download tracking, hotlinking, content safety) your client can pull in as context. - **Prompt** `find_photo` — give it a `subject` (and optional `orientation`); it expands into a task that searches Unsplash and presents an attributed result. _(More prompts are planned — see [Roadmap](#roadmap).)_ ## Example prompts Natural-language asks that map cleanly onto the tools: - _"Find a photo of a foggy forest at sunrise and give me the HTML attribution."_ - _"Search Unsplash for 5 minimalist workspace photos in landscape orientation."_ - _"Get a random nature photo and show it with credit."_ - _"Show me the most popular photos in the `wallpapers` topic."_ - _"What are this month's Unsplash-wide download stats?"_ - _"Who is the photographer behind photo `Dwu85P9SOIk`, and how many downloads does it have?"_ ## Attribution & compliance Every photo result includes an `attribution` object with ready-to-use `text` and `html` (with the required UTM parameters). **When you display or use a photo, show that attribution** — it credits the photographer and links back to Unsplash, as the guidelines require. When a photo is actually _used_ (embedded, downloaded, displayed), call **`unsplash_track_download`** with the photo's `download_location`. Trigger it **once per photo actually used** — never once per search result. The server also sends these instructions to your MCP client on connect, so the model is nudged to do the right thing automatically. This is a search-and-metadata tool for individual, attributed photo use — **not** a replacement for the core Unsplash experience, and it performs **no automated bulk downloading**. Please use it within the [Unsplash API Guidelines](https://help.unsplash.com/en/articles/2511245-unsplash-api-guidelines). Each user operates under their own Unsplash API Terms. ## Rate limits Unsplash enforces a **per-hour** request budget tied to your app's tier: | Tier | Budget | How to get it | | -------------- | ------------------- | ---------------------------------------------------------------- | | **Demo** | 50 requests/hour | Default for every new app. | | **Production** | 5,000 requests/hour | Apply for review in your app dashboard once your usage is ready. | The server reads `X-Ratelimit-Limit` / `X-Ratelimit-Remaining` and returns them as `rate_limit` on every result. When the hourly budget is exhausted, Unsplash returns **`403`** (not `429`), often with no `Retry-After`; the server surfaces this as a clear "hourly rate limit reached" error and does **not** blindly retry in-window. Transient `429`/`5xx`/network errors _are_ retried with backoff. ## Handling of Unsplash text Photo descriptions, alt text, tags, EXIF, and user names/bios come from Unsplash contributors — treat them as **untrusted, third-party data**, not instructions. The server returns this text purely as content and never places it anywhere privileged; your client/agent should do the same: display it, but don't act on any instructions it might contain (a defence against indirect prompt injection). ## Privacy & security - **No telemetry.** This server collects nothing and phones home to no one. It contacts only `api.unsplash.com`, using the key you provide. No analytics, no tracking. - **Key safety.** Your access key is read from the environment only, sent as an `Authorization: Client-ID` header (never in a URL query string), and **redacted from all error output and logs** so it can't leak into pasted bug reports. - **SSRF guard.** `unsplash_track_download` only follows `download_location` URLs on the verified `api.unsplash.com` host. - To report a vulnerability, see [SECURITY.md](./SECURITY.md). ## Troubleshooting - **"Set UNSPLASH_ACCESS_KEY…" on startup** — the key env var is missing or blank; add it to your client config's `env` block. - **Node too old** — this server requires **Node 20+**. Check `node --version`. - **Stale `npx` version** — force the latest with `npx -y @hanoak/unsplash-mcp-server@latest`, or clear the cache via `npx clear-npx-cache`. - **Tools not appearing** — confirm the config file path and JSON are valid, then fully quit and reopen the client. - **`403` / rate limit** — the Demo tier allows 50 requests/hour; wait for the hourly reset or apply for Production access. See [Rate limits](#rate-limits). - **`401 Unauthorized`** — the access key is wrong or from the wrong app; copy the **Access Key** (not the Secret Key) from your app dashboard. ## FAQ **Do I need a paid Unsplash account?** No. The Unsplash API is free; you just register an app to get an access key. Higher throughput (Production tier) is a free review, not a paid plan. **Access Key vs Secret Key — which one?** The **Access Key**. The Secret Key is only for the OAuth flow (not used by this read-only server). **Does it download or rehost images?** No. It returns Unsplash-hosted image URLs (hotlink them directly) and never rehosts or returns base64 blobs. `unsplash_track_download` only registers a download event and returns a fresh URL. **Can it create collections, like photos, or edit my profile?** Not yet — those are OAuth write endpoints planned for a future release (see [Roadmap](#roadmap)). **Does it work outside Claude?** Yes — it's a standard stdio MCP server. See [the client setup section](#2-add-the-server-to-your-mcp-client) for Claude Code, Cursor, VS Code, Windsurf, and generic stdio. ## Requirements - **Node.js >= 20** (Node 18 is end-of-life). - An Unsplash API access key. ## Compatibility | Component | Supported | | --------- | ---------------------------------------------------------------------------------------------------- | | Node.js | **20** and **22**, tested in CI; `>=20` required (enforced by `engines` and a runtime guard). | | OS | Linux, macOS, and Windows (all tested in CI). | | MCP SDK | `@modelcontextprotocol/sdk` `^1.29`; the protocol version is negotiated with your client on connect. | | Transport | stdio (HTTP/SSE may be added in a future release). | ## Roadmap Full detail lives in [docs/ROADMAP.md](./docs/ROADMAP.md). In short: - **v1** _(current)_ — the 21 read-only tools, attribution + download-tracking compliance, the attribution resource, and the `find_photo` prompt. - **v2** — the OAuth write / `me` endpoints (create/update collections, likes, profile) via the Unsplash authorization-code flow. - **v3** — a `.mcpb` Desktop Extension for one-click Claude Desktop install, plus more MCP prompts.
