"Projects that showcase advanced GitHub repository search techniques" matching MCP connectors:

Read-only breach intel, full history 2007-today: reports THAT an org was breached, never the data.

Discovery, OAuth, project operations, and exact project MCP handoff for Spala backend projects.

Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

Renamed to FactReason. Now published as io.github.factreason/factreason — please use that entry.

Search newly registered, expired, aged, active, deleted and for-sale domains, plus WHOIS and DNS.

Email OS for agents - real-inbox search, triage, commitments, and a verifiable BEC hard-stop.

Detect malicious or vulnerable npm packages: registry search, OSV.dev and GitHub advisory lookups

GitHub Private MCP Pack — access private repos, org data via OAuth.

urlscan.io URL scanner — search/result keyless, submit needs key

Independent static verification for exact immutable public GitHub commits.

Linux package, file, command, vulnerability, lifecycle, migration, and repository intelligence.

Breach intelligence API: email search, domain monitoring, passwords and stealer logs.

Pre-signature x402 payment-risk oracle. AI agents call forecast_payment before paying a counterparty and get a GO / HOLD / STOP verdict from settlement reputation, price-anomaly (quoted vs the payee's own median), and OFAC sanctions screening — plus a third-party-verifiable Ed25519 signed receipt. Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.

Search a directory of SOC 2 audit and compliance firms; read GRC migration guides. Read-only.

MCP enforcement layer that intercepts AI agent actions and blocks rule violations before execution.

Search vetted privacy tools, read guides & glossary, and run free privacy diagnostics.

Scan any public GitHub MCP-server repo for security issues. 37 MCP-specific L1 rules, 8 languages.

The MCP server that vets MCP servers: identity, risk grade and per-tool risk before you install.

PQC scanner for GitHub repos and smart contracts. Detects quantum-vulnerable ECDSA/RSA.

Deterministic safety, correctness & cost gate that vets Postgres SQL before your AI agent runs it.
