Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Semgrep
MCP server for using Semgrep to scan code for security vulnerabilities.
contract-decoder
Decode and reverse-engineer smart contract binaries for security research. Solana: extract instructions, discriminators, PDAs, and error codes from .so files. EVM: decompile bytecode to recover function selectors and storage layout. Use for bug bounty recon, verifying deployed code, or analyzing closed-source contracts.
