## mcp.so

mcp.so organises the fast-growing Model Context Protocol ecosystem in one searchable place. You can browse servers by category (developer tools, AI and agents, cloud infrastructure, memory and knowledge, media and design), inspect remote endpoints, and read setup details before wiring a server into Claude, Cursor or another MCP-compatible client. Featured and trending sections surface popular or newly added servers, and rankings help you gauge what the community is adopting.

Beyond raw server listings, the site collects MCP clients (apps, IDEs and frameworks that speak the protocol), official CLI tools such as Bun, Cloudflare Wrangler, DuckDB and FFmpeg, reusable agent loops and skills, and curated collections. A feed tracks new arrivals, and submit/claim flows let maintainers add or take ownership of their own listings.

For anyone building with AI agents, mcp.so works as a discovery and reference layer: pick a capability, check how the server connects and authenticates, follow the setup guide, and keep an eye on what the community is installing each week. It is a directory, so it does not itself host or run the servers it lists.

**Pricing & Plans:** Free to browse and use the directory. Advertising, featured placement and claiming listings are handled through the site; no subscription is required for normal browsing.

- **Searchable MCP server directory:** Find servers by name, category, tag, runtime or integration, with featured, trending and newest sections that track community activity.
- **Remote endpoints and setup guides:** Review hosted MCP endpoints, authentication requirements and per-client setup instructions before you connect anything.
- **Clients, CLI tools and skills:** Discover MCP-compatible clients, official command-line tools, agent loops and reusable Claude/Codex skills in dedicated sections.
- **Submit and claim listings:** Maintainers can publish new servers and claim existing listings so entries stay accurate and attributable.
- **Categories, rankings and feed:** Browse top categories, compare curated selections and follow a live feed of newly added servers, tools and skills.

**Strengths:** Broad, regularly updated coverage of MCP servers and clients; Setup and authentication details gathered together in one place; Free to use with no account needed for browsing; Includes CLI tools, agent skills and curated collections beyond raw listings

**Limitations:** Listings are community-submitted, so quality and freshness can vary; It is a directory only, not a place to run or host MCP servers; Ad and featured placements can push less relevant results higher

## Museum of Models (Rival)

Museum of Models — the project formerly known as Rival — is a free, ad-free archive of how AI models actually answer. Since May 2024, the same 100 questions have been put to every model in the exact same way, once, and every answer has been kept exactly as it was given, including the odd ones and the empty ones. The result is 18,773 answers from 385 models, a record of how each one drew a pelican, built a landing page, told five jokes, or named a favourite city.

The premise is that leaderboards only remember scores. When a lab retires a model and switches it off, its weights often disappear and nobody can ask it anything again. The museum keeps the outputs themselves: 121 of the 385 models featured are no longer served on OpenRouter, yet their drawings, websites, writing and image answers are still here to browse.

Nothing on the site is ranked or scored, and supporting it changes nothing about what it shows. Answers are presented in their native form — drawings as SVG, websites running live in a sandbox, images as pictures, writing as readable pages and voices you can play. Visitors can spin an interactive globe of answers, compare two to four models side by side, sort by release date, lab or question, and step back through a monthly timeline of the museum since it opened. The full collection is downloadable and reusable under CC BY 4.0 with credit.

**Pricing & Plans:** The museum is completely free with no ads. Hosting costs are covered by voluntary donations, such as buying the creator a coffee, and all answer data can be downloaded and reused under CC BY 4.0 with credit.

- **18,773 answers from 385 models:** One hundred identical questions covering drawings, websites, writing, images, code and audio, each answered by every model and kept as given.
- **Retired models preserved:** 121 of the 385 models are no longer served on OpenRouter, yet their answers remain viewable, preserving outputs that would otherwise be lost.
- **Side-by-side comparison:** Add two to four models with a single click and view their answers to the same questions next to each other.
- **Interactive globe and index:** Explore a magnifiable globe of answers, an index sortable by release date, lab or question, a monthly timeline, and a fast command-K search.
- **Live, runnable exhibits:** Generated websites run live in a sandbox, drawings are the model's own SVG, images are shown at 640px, and voices can be played directly.

**Strengths:** Completely free and ad-free, with no login required; Preserves answers from models that have since been retired and switched off; Methodologically consistent: identical prompts, one attempt, documented settings; Open data downloadable under CC BY 4.0 and explorable through globe, index and side-by-side views
