"OpenSSL" matching MCP servers:

Provides a unified tool for TLS certificate analysis with automatic OpenSSL integration, allowing users to fetch, analyze and assess security of TLS certificates without manual PEM handling.

Enables agents to cryptographically verify JWT HMAC-SHA256 signatures, validate claims and enforce expiration, and perform Merkle inclusion proofs, Schnorr zero-knowledge identification, and nonce replay protection. Runs as a zero-dependency stdio MCP server so clients like Claude Desktop, Cursor, and Windsurf can attest execution state without OpenSSL or external libraries.

Enables MCP clients to search documents stored in OpenSQL/PostgreSQL using vector similarity, with support for version history and changelog retrieval.
