- What it is: “Elicitation” is a fancy word for “asking for.” In the context of MCP, it’s a secure way for the system to pause and ask the user for information. “Native MCP Elicitation Auth” means that HasMCP has built-in support for using this “asking” mechanism to handle authentication, specifically with OAuth2.
- Why it’s important: You can’t just give an LLM your username and password. That would be a huge security risk. Instead, modern applications use protocols like OAuth2, where you are redirected to a trusted website (like Google or your corporate login page) to sign in. HasMCP’s Elicitation Auth manages this process.
- How it works:
- The LLM decides it needs to use a tool that requires you to be logged in.
- HasMCP, acting as the MCP server, detects this and initiates the OAuth2 flow.
- It then “elicits” your permission by providing a secure URL. You, the user, would then click this link, which takes you to the standard login page.
- After you successfully log in, the authentication service sends a secure token back to HasMCP.
- HasMCP can then use this token to make API calls on your behalf.
- Key benefits:
- Security: Your credentials are never exposed to the LLM or stored in an insecure way. The process follows industry-standard security protocols.
- User Experience: You get the familiar “Log in with…” experience you’re used to in other applications.
- Automation: The process is handled automatically by HasMCP, so developers don’t have to build this complex authentication logic themselves.
