authprobe vs rust-mcp-sdk
authprobe: `authprobe` is a diagnostic tool designed to pinpoint and troubleshoot failures in the Model Context Protocol (MCP) OAuth authentication flows. It scans the discovery process, identifies divergences from specifications, and provides detailed reports including RFC-based explanations and network traces to help resolve compliance issues.; rust-mcp-sdk: Rust MCP SDK is a high-performance, asynchronous Rust toolkit designed for building MCP (Model Context Protocol) servers and clients. It abstracts away protocol details and transport mechanisms, allowing developers to concentrate on their core application logic. The SDK provides comprehensive support for the latest MCP protocol, including various transports and powerful procedural macros for streamlined development.
01
TL;DR
Choose authprobe if…Validating OAuth discovery and protected-resource metadata behavior for MCP server authors.
Choose rust-mcp-sdk if…Building high-performance MCP servers that interact with various clients using different transport mechanisms (Stdio, HTTP).

Features
authprobe01Pinpoints MCP OAuth failures by walking the discovery flow and reporting divergences from spec.
02Provides a "funnel view" output to visualize where issues broke in the authentication chain.
03Offers RFC-based explanations and detailed network traces for failed probe steps.
04Supports LLM-powered explanations of RFC compliance gaps, with options for OpenAI or Anthropic.
05Generates comprehensive outputs like Markdown, JSON reports, and sanitized evidence bundles for troubleshooting.
rust-mcp-sdk01Supports the latest MCP protocol specification (2025-11-25) with backward compatibility.
02Provides multiple transport options: Stdio, Streamable HTTP, and backward-compatible SSE.
03Includes a lightweight Axum-based server for Streamable HTTP and SSE with multi-client concurrency.
04Offers powerful procedural macros (mcp_tool, mcp_elicit, etc.) for type-safe schema and user input elicitation.
05Supports OAuth Authentication for MCP Servers, including Remote Oauth Provider integration with Keycloak, WorkOS, and Scalekit.

Use Cases
authprobe↳Validating OAuth discovery and protected-resource metadata behavior for MCP server authors.
↳Debugging where auth flows diverge from RFC 9728 / RFC 8414 for MCP client implementers.
↳Triaging auth regressions in CI before rollout for platform, security, and infra teams.
↳Generating reproducible evidence bundles for handoff across organizational boundaries for API teams.
↳Setting up recurring protection and regression tripwires in CI/CD pipelines (e.g., GitHub Actions).
rust-mcp-sdk↳Building high-performance MCP servers that interact with various clients using different transport mechanisms (Stdio, HTTP).
↳Developing custom MCP clients to communicate with MCP servers, manage tools, and handle messages.
↳Integrating filesystem operations into MCP applications using the rust-mcp-filesystem project.
↳Creating AI-powered applications that leverage MCP for tool calls and structured interactions, as seen in projects like mistral.rs and text-to-cypher.
↳Developing command-line tools for discovering and documenting MCP Server capabilities (e.g., MCP Discovery).
