MCPifex vs. Smithery: Hosted MCP and Connection Control

Smithery MCP is a platform for finding MCP servers, connecting to them with managed authentication, and publishing your own. MCPifex is a hosted gateway: it runs a set of MCP servers for you behind one URL. Pick Smithery for the widest catalog. Pick MCPifex when you want tight control over which tools an AI can call.

The short version

What Smithery does

Smithery started as a CLI for installing MCP servers into a client, and older tutorials still show @smithery/cli install. As of September 2026 its site describes something broader: a connection platform where Smithery handles auth, credentials and sessions so an agent can reach thousands of tools.

The current CLI is published on npm as smithery and needs Node 20 or newer. You log in with smithery auth login, add servers with smithery mcp add, and call tools directly with smithery tool call. The CLI code is public on GitHub.

Smithery also serves people who build servers. You can publish to its catalog as a hosted release, an external endpoint or a stdio bundle, and get distribution and observability in return. Its connection guide covers OAuth, automatic token refresh and encrypted, write-only credential storage.

What MCPifex does

You create an instance of a hosted server in the portal, save that server's credentials, and choose which tools are on. Then you generate an API key and point any MCP client at the gateway. We run the real server package. You never install it.

Every call is logged per instance, so you can see what an agent did. A "Test connection" step makes a real health-check call before you finish setup. For the background, see what an MCP gateway is and what an MCP server is.

Catalog breadth or tool control?

This is the real difference. Smithery's large directory is useful for finding a specialized integration and connecting it through one auth flow. A big catalog doesn't tell you how a given server is deployed, though, so check each listing's release type and credentials.

MCPifex is smaller on purpose. Its hosted servers, such as PostgreSQL, come with per-instance tool controls. Write and delete tools start off. The tool list is filtered to what you enabled, and a call to anything else is refused.

A concrete case: the PostgreSQL package has a connect_db tool that could point the server at a different database. It isn't in our catalog, so it is always refused. A client can never redirect the connection.

How each handles access control

Smithery's token-scoping docs describe server-enforced policies on connections. You can filter by metadata, restrict operations, set an expiry, and issue narrower child tokens. That's a strong way to separate users and limit what one token can do.

MCPifex works one level down. You switch individual tools on or off per instance. The two ideas overlap but aren't identical, so ask which one you need: separating users' connections, limiting tools inside a connection, or both.

Clients that can't send headers

Some clients, like ChatGPT connectors and claude.ai custom connectors, can't attach an Authorization header. An MCPifex key works either as a Bearer header or as the first path segment of the URL: https://mcpifex.com/mcp/mcpx_.... Treat that whole URL as a password.

Revoking a key stops new calls within about a minute. An open session is cut off on its next tool call. Smithery has its own managed connection flows, so test your exact client against its instructions.

Is Smithery the official MCP Registry?

No. The official MCP Registry stores metadata so people can discover servers. It doesn't run them. Smithery and MCPifex are separate products with their own catalogs and connection workflows.

Which should you choose?

• Choose Smithery if you want to search a very large catalog, you're happy with each listing's own install and auth path, or you plan to publish a server of your own.
• Choose MCPifex if one of its hosted servers covers your need and you want one endpoint, per-tool switches, call logs, and a key that works in any client.

Not sure? Try one small task on each with test data only. Run an allowed call, then a call to something that should be blocked, and note which layer refuses it.
