Model Context Protocol TypeScript SDK authorization discovery nested /.well-known/oauth-protected-resource/mcp oauth-authorization-server
💡 Result:
The Model Context Protocol (MCP) uses standardized well-known URIs to facilitate authorization discovery, enabling clients to securely locate and interact with authorization servers [1][2]. MCP servers acting as OAuth resource servers implement discovery by hosting metadata at specific paths [3][4]. /.well-known/oauth-protected-resource/mcp (Path-Aware) This endpoint serves the RFC 9728 Protected Resource Metadata [5][3]. When an MCP server is hosted at a path (e.g., /mcp), the specification requires that the path component be inserted into the well-known URI [6][4]. For a server at https://example.com/mcp, the discovery document is served at https://example.com/.well-known/oauth-protected-resource/mcp [1][7]. This ensures path-scoped resources are correctly identified [8][6]. /.well-known/oauth-authorization-server This endpoint serves the RFC 8414 Authorization Server Metadata [3][4]. It acts as a mirror, allowing legacy or directly probing clients to discover the authorization server metadata without first traversing the protected resource metadata document [3][4]. TypeScript SDK Support The MCP TypeScript SDK provides middleware and utility functions to automate this implementation [9][3]: - Server-side: The @modelcontextprotocol/server (and @modelcontextprotocol/express) package offers mcpAuthMetadataRouter and oauthMetadataResponse() to correctly serve these discovery endpoints [10][3][4]. - Client-side: The high-level client uses these well-known URIs to discover the authorization server [1][3]. If a server returns a 401 Unauthorized response, the client uses the information in the WWW-Authenticate header (pointing to the resource metadata) to discover the necessary authorization server and proceed with the OAuth flow [11][3]. For further implementation details, the official MCP TypeScript SDK documentation provides specific guides on authorization, including how to structure these endpoints for both Express and generic web-standard fetch handlers [9][3][4].

Cloudflare Access application path matching wildcard path policy bypass exact path /.well-known/*
💡 Result:
In Cloudflare Access, there is no direct mechanism to "exclude" or bypass a specific path within a broader protected application by simply adding a policy rule. When a user experiences issues with path-based resources—most commonly the /.well-known/acme-challenge/* path used for SSL certificate renewals—the standard and recommended solution is to create a separate, more specific Access application [1][2]. Because Cloudflare Access prioritizes the most specific hostname and path definition [3], creating a dedicated application for the specific path (e.g., example.com/.well-known/) allows you to define a bypass policy that takes precedence over the broader policy covering the rest of the site [1]. To implement this: 1. Create a new Access Application specifically for the path you need to bypass (e.g., example.com/.well-known/). 2. Configure the policy for this new application to use the Bypass action [4]. 3. Set the rule to include everyone or specific IP ranges, ensuring the required traffic (like the ACME challenge) is not intercepted by the authentication middleware [4][1]. Without this explicit separation, a broad policy (such as one covering example.com/*) will apply its authentication requirements to the entire path space, effectively blocking the traffic you intend to expose [5][1]. This approach essentially treats the bypass as a higher-priority "match" because it is more specific than the wildcard or apex-level policy [3]. Documentation confirms that for tunnels, it is also essential to ensure these public hostnames are correctly configured and, if necessary, ordered correctly within the tunnel settings to ensure the bypass application intercepts the traffic before the restricted application [6].

💡 Result:
I couldn’t find an indexed result for kody-bot/home-mcp-starter/cloudflare-access.md. The closest relevant guidance indicates that Cloudflare Access MCP setups should allow unauthenticated access to OAuth discovery endpoints under /.well-known/; otherwise clients cannot complete discovery. (developers.cloudflare.com)
Likely Access bypass paths include:
/.well-known/*/authorize/token/register
These should be bypassed only when required by the MCP OAuth flow; the actual MCP endpoint should remain protected. (github.com)

Cloudflare Access self-hosted application path "/.well-known" matches nested paths wildcard
💡 Result:
In Cloudflare Access, application path matching uses wildcards (*) to extend coverage to nested paths [1]. When you define an application path, the * character acts as a wildcard for zero or more characters [1][2]. If you configure an application with a path like /.well-known/*, it will match the root /.well-known/ (if specified) and all nested paths under it, such as /.well-known/example or /.well-known/subdir/file [1]. Key considerations for this configuration include: 1. Matching Behavior: Using a wildcard in the path field follows standard Cloudflare Access rules: - example.com/.well-known/* covers paths like example.com/.well-known/foo and example.com/.well-known/bar/baz [1]. - It does not cover the parent directory if the wildcard is used to define a specific sub-path (e.g., example.com/alpha/* does not cover example.com/alpha) [1]. - There is a restriction of at most one wildcard between each slash in the path [1]. 2. Precedence: Cloudflare Access evaluates policies in a specific order (Bypass, Service Auth, then Allow/Block) [3]. If you need to allow public access to /.well-known/ while protecting the rest of your application, you should create a separate Access application or an explicit Bypass policy for the desired path [4][5]. Be aware that the most specific hostname and path definition takes precedence [2]. 3. Special Note on .well-known: While you can use wildcards to match these paths, keep in mind that Cloudflare Access reserves certain /.well-known/ paths for internal functionality, such as Managed OAuth or identity provider metadata [6][7][8]. If your application also serves content at these paths, ensure your policy definitions do not conflict with these reserved endpoints [9].

Use /.well-known/* for the Access bypass.
The starter serves /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource/mcp. An exact /.well-known path does not cover these nested routes, which blocks OAuth discovery.
