mcp-server-outh2 by kamarthiparamesh - MCP Server

The MCP server is a pivotal component in the Model Context Protocol ecosystem, providing a secure and structured way to expose tools, resources, and prompts to authorized clients. By leveraging OAuth 2.0, the server ensures that only authenticated users can access its offerings, thereby maintaining the integrity and confidentiality of the data and services it provides. The integration with Affinidi Login as the external authorization provider exemplifies a real-world application of OAuth 2.0, showcasing how third-party authentication can be seamlessly incorporated into a server-client architecture. This setup not only enhances security but also simplifies the user experience by allowing users to authenticate using a trusted external provider. The MCP server is particularly useful for developers looking to implement secure resource access in their applications, providing a reference implementation that can be adapted to various use cases. Despite a known issue with the SDK's handling of the authorization code exchange flow, a local modification has been made to ensure compliance with the OAuth 2.0 specification, thereby ensuring the flow operates as intended.
