Browse all Model Context Protocol servers with quality scores, stars, languages and maintenance activity.
Exposes the RSigma Sigma detection-engineering toolkit to AI agents over stdio or Streamable HTTP with `rsigma mcp serve`. Tools to author, lint, validate, and convert Sigma detection rules, evaluate and explain detections against log events, and inspect correlation state, all backed by a native Rust engine.
Policy-as-code gate for MCP. A fail-closed proxy that denies risky tool calls before they run, produces offline-verifiable evidence bundles of what executed, and enforces IPv4/TCP egress in-kernel via eBPF/LSM and Landlock on Linux. Deterministic and offline-first.
Policy enforcement for AI coding agents derived from existing instruction files (CLAUDE.md, .cursorrules, .windsurfrules, .github/copilot-instructions.md) — no separate YAML to maintain. Rules with prohibitive predicates (`never`, `forbids`, `must_not`) emit `permissionDecision: deny` to block tool calls in Claude Code; advisory rules inject context. PostToolUse is correlated with PreToolUse to pr
Local guardrail proxy for AI coding agents. Wraps any MCP server (stdio or Streamable HTTP) and blocks destructive tool calls — DROP TABLE, rm -rf, force-push — before they execute. MCP supply-chain protection: TOFU tool-catalog pinning against rug pulls, plus tool-description and tool-result scanning for tool poisoning and prompt injection. 51 starter rules, approval gates, audit logging. Single
A Rust-based MCP server bridging Wazuh SIEM with AI assistants, providing real-time security alerts and event data for enhanced contextual understanding.
Local-first MCP gateway for coding agents that redacts detected secrets from file reads and command output before they reach model context.
Rust infrastructure diagnostics MCP server for AI agents: DNS checks, TLS certificate chain inspection, email security, global DNS propagation, and DNS latency benchmarking.
A Rust-based MCP server to integrate Cortex, enabling observable analysis and automated security responses through AI.
A Rust-based MCP server to integrate TheHive, facilitating collaborative security incident response and case management via AI.
Solvitor MCP server provides tools to access reverse engineering tools that help developers extract IDL files from closed-source Solana smart contracts and decompile them.
