Class McpProtectedResourceMetadataServlet

java.lang.Object
jakarta.servlet.GenericServlet
jakarta.servlet.http.HttpServlet
com.xebialabs.xlrelease.mcp.oauth.McpProtectedResourceMetadataServlet
All Implemented Interfaces:
jakarta.servlet.Servlet, jakarta.servlet.ServletConfig, Serializable
public class McpProtectedResourceMetadataServlet extends jakarta.servlet.http.HttpServlet
Serves the OAuth 2.0 Protected Resource Metadata (RFC 9728) for the MCP endpoint, so MCP clients (Claude, etc.) can discover the OIDC authorization server protecting /s/mcp and run the OAuth 2.1 + PKCE flow on their own. Mounted at /.well-known/oauth-protected-resource and /.well-known/oauth-protected-resource/*; only the bare path and the MCP resource path suffix (e.g. /s/mcp) are answered, anything else is 404.

Answers 404 while the MCP server feature is disabled (mirroring McpServerEnabledFilter) or when no OIDC issuer is configured. Purely additive: it never affects which credentials the MCP endpoint accepts.

      public McpProtectedResourceMetadataServlet(Supplier<String> serverUrl, String mcpResourcePath, Supplier<String> issuer, BooleanSupplier mcpServerEnabled, List<String> scopesSupported)
      Parameters:
      serverUrl - supplier of the public server base URL (read per request so runtime changes to the configured server URL are reflected immediately)
      mcpResourcePath - the MCP endpoint path relative to the server root, e.g. /s/mcp
      issuer - supplier of the configured OIDC issuer URL (may return null/blank)
      mcpServerEnabled - runtime MCP server feature toggle
      scopesSupported - scopes to advertise as scopes_supported (xl.features.mcp.server.oauth.scopes-supported); MCP clients request exactly these when registering with the OIDC provider instead of guessing from the provider's full scope list. Empty list omits the field.
