".NET" matching MCP servers:

Enables AI agents to perform passive security scans on domains, checking email spoofing (DMARC/SPF/DKIM), TLS weaknesses, security headers, exposed files, and subdomain-takeover risk without needing an API key.

Open-source .NET framework and server for Model Context Protocol (MCP) with enterprise OAuth 2.0/OIDC auth, per-tool MFA, OpenTelemetry, and health checks.

A pentesting toolkit that runs as an MCP server, providing AI assistants structured access to 22 security tools through a safety-hardened interface.

Protect against malicious open source packages 🤖

A proof-of-concept HTTP MCP server requiring OAuth 2.0 authentication before tool use. Demonstrates the full authentication flow with Claude Code, including discovery, client registration, PKCE authorization, and bearer token verification.

MCP server for NextDNS that enables managing profiles, blocklists, analytics, DNS logs, and parental controls through natural language.

MCP server that vets LLM-emitted shell commands BEFORE execution — detects rm -rf nested deep in chains, package-manager glob removal (apt remove 'nvidia'), dd/mkfs filesystem destruction, chmod 777 / chown -R privilege blast, network-exfil via curl | bash, chained shutdown/reboot, git destructive ops. 30 detection rules across 8 families. Sub-second, local, free, MCP-native.

Enables agentic coding clients to enforce portable policy guardrails by evaluating proposed shell, file write, git, and network actions and returning allow, deny, or ask decisions.

Trust-scan gate for MCP servers: evidence-backed verdicts before you install.

Enables connecting a single OAuth-capable MCP client, such as ChatGPT, to bearer-token upstream MCP servers while managing an encrypted pool of authorized provider credentials for session affinity, load distribution, and failover.
