MCP.so is one of several directories that emerged to help developers find MCP (Model Context Protocol) servers for their AI assistants. With MCP adoption growing rapidly across Claude Desktop, Cursor, and other AI coding tools, having a reliable place to discover and evaluate servers matters. We tested MCP.so's search, categorization, and server listings to see how it stacks up against alternatives like MCP Hub and Smithery.
What We Like
- Clean, searchable interface for finding MCP servers
- Good coverage across server categories
- Direct links to GitHub repos for transparency and code review
- Regular updates as new servers are published
What Could Be Better
- Directory only — no hosting, management, or monitoring features
- Less curation than MCP Hub — quantity over quality filtering
- No built-in installation tooling
- Community is still growing
Features Deep Dive
MCP.so's feature set is intentionally narrow: search, browse by category, and view server details. The search is keyword-based and works well for finding specific server types (e.g., 'postgres', 'slack', 'filesystem'). Server listings include descriptions, GitHub links, download/star counts, and compatible clients. Category filtering covers database, API, file system, communication, and more. What's missing is hosting, installation tooling, quality scoring, or any managed service — MCP.so is purely a discovery layer.
Pricing Breakdown
MCP.so is completely free. There are no paid plans, premium features, or gated content. The business model appears to be community-driven, similar to other open-source directories. This makes it a zero-risk option to check when searching for MCP servers.
Content Quality Assessment
MCP.so's directory coverage is broad — it lists a large number of servers across many categories. The trade-off is less curation than MCP Hub or Smithery. Some listed servers are experimental, unmaintained, or poorly documented, and MCP.so doesn't filter these out as aggressively. The popularity metrics (stars, downloads) help surface actively maintained projects, but users should still evaluate server quality independently before integrating.
Interface and Discovery
The interface is clean and fast. Search results load quickly, category pages are well-organized, and server detail pages give you what you need — description, GitHub link, compatibility info — without clutter. Navigation is intuitive and the overall design prioritizes function over form. For a free directory, the UX quality is solid.
Who Is MCP.so Best For?
MCP.so is best for developers who want a quick, no-frills way to search for MCP servers. If you know roughly what you're looking for — a database connector, a file system server, an API integration — MCP.so's search and filtering will get you there fast. It's less useful if you need hosting, installation tooling, or deep quality curation. For those needs, Smithery or Glama are better options.

MCP.so is purely a directory — it lists servers with descriptions and GitHub links. Smithery adds hosting, installation tooling, and a registry API. If you just need to find servers, MCP.so works fine. If you want managed hosting or one-click installs, Smithery offers more.
Can I submit my own MCP server to MCP.so?
Yes. MCP.so accepts community submissions. You can submit your server's GitHub repo for inclusion in the directory.
