What It Does

Details

MCP-identity provides cryptographic attestation for individual HTTP requests to MCP servers. It signs each request with a user's key over the exact payload, enabling server-side verification of request authorization. This ensures actions like data deletion or transactions can be proven to have user approval.

Who It's For

Best fit users

  • Developers integrating MCP servers
  • Security professionals
  • Auditors requiring request-level validation
Why It Matters

Why this one made the cut

OAuth alone cannot prove a user authorized the exact request. MCP-identity adds non-repudiation and per-request audit trails, helping prevent disputes over high-stakes operations like financial transactions or sensitive data modifications.

Differentiator

What makes it different

Works alongside OAuth instead of replacing it, using a single HTTP header for integration with minimal overhead.
