Building MCP Servers

Mon, 01 Jan 0001 00:00:00 +0000

Authorization

Mon, 01 Jan 0001 00:00:00 +0000

The MCP authorization specification defines the OAuth 2.0-based flow that remote MCP servers use to authenticate clients, and it is the formal basis for everything the higher-level registry authentication guide simplifies. Focus on the required OAuth grant types, token scoping rules, and the metadata discovery mechanism that clients use to find a server’s authorization endpoint. A key gotcha is that the spec mandates specific OAuth metadata fields that many generic OAuth libraries do not populate by default, so you may need custom configuration even when using well-known auth frameworks. This is dense specification text best read alongside a working implementation for reference.

How to Authenticate When Publishing to the Official MCP Registry

Mon, 01 Jan 0001 00:00:00 +0000

Authentication is the first barrier you will hit when trying to publish an MCP server to the official registry, and getting it wrong means silent failures with unhelpful error messages.
