SchemaPin 🧷

What is SchemaPin?

SchemaPin is a cryptographic protocol designed to ensure the integrity and authenticity of tool schemas used by AI agents, preventing supply-chain attacks by allowing developers to cryptographically sign their schemas and enabling clients to verify their authenticity.

How to use SchemaPin?

Tool developers can sign their schemas using the provided Python or JavaScript libraries, while AI clients can verify these schemas by fetching the signature and public key, ensuring that the schemas have not been altered since publication.

Key features of SchemaPin?

• Strong security with ECDSA P-256 signatures and SHA-256 hashing.
• Cross-language support with implementations in Python and JavaScript.
• Simple integration with high-level APIs for developers and clients.
• Trust-On-First-Use (TOFU) key pinning to prevent key substitution attacks.
• Compliance with RFC 8615 for public key discovery.

Use cases of SchemaPin?

1. Signing and verifying AI tool schemas to prevent unauthorized modifications.
2. Ensuring the integrity of schemas in AI applications to mitigate supply-chain risks.
3. Facilitating secure communication between AI agents and their tools.

FAQ from SchemaPin?

• Can SchemaPin be used with any AI tool?

Yes! SchemaPin is designed to work with any AI tool that requires schema verification.

• Is SchemaPin open-source?

Yes! SchemaPin is available on GitHub under the MIT License.

• How does SchemaPin enhance security?

By using cryptographic signatures and key pinning, SchemaPin ensures that only verified schemas are used, reducing the risk of supply-chain attacks.
