"Understanding Feedback Enhanced Concepts or Technologies" matching MCP servers:

A zero-dependency Node.js playground for debugging how MCP clients authenticate to an MCP server over HTTP.

A 7-layer security system for AI agents that detects and blocks prompt injection, data exfiltration, and malicious tool calls. It enables real-time scanning of inputs, outputs, and tool definitions to protect agentic workflows from emerging AI-specific threats.

Enables natural language interaction and management of pfSense firewalls through Claude and other GenAI applications using the Model Context Protocol. It provides advanced tools for firewall rule configuration, interface management, and intelligent log analysis via a REST API integration.

MCP server for managing Ory Kratos identities, sessions, and authentication flows, enabling AI assistants to perform identity management tasks via natural language.

Connects Claude Desktop to the Paylocity API to manage employee records, pay statements, and company headcount data through natural language. It includes automated data protection that redacts sensitive information like SSNs and bank account numbers before reaching the model.

Multi-perspective code analysis using Claude Code, Codex, and Antigravity CLI agents to provide direct, honest technical feedback on code, architecture, and ideas.

Transparent Go proxy that intercepts, signs, rate-limits, redacts, and audits all MCP JSON-RPC tool calls without modifying client or server. Stores to JSONL or SQLite with HMAC-SHA256 signatures.

Provides real-time policy enforcement for AI coding agents by intercepting and validating their actions against organizational standards like naming conventions, security policies, and compliance rules before execution. Prevents violations through immediate feedback and auto-correction suggestions.

MCP server for Quackr, enabling virtual phone number management including balance checking, pricing, inventory, purchasing numbers, and reading SMS via Claude or any MCP-compatible client.

Scans generated JavaScript/TypeScript code to detect AI-hallucinated or suspicious npm package imports before installation, providing a verdict of CLEAN, REVIEW, or BLOCK.

Enables secure delivery of Bitwarden Secrets Manager secrets to approved local files without exposing secret values to the MCP client or model. It provides metadata-only secret discovery and atomic file writes for single secrets or raw env files.

Enables AI agents to access VirusTotal intelligence through MCP, supporting file, URL, domain, and IP lookups, plus analysis, via remote HTTP or local stdio.

A prompt-validation service that checks incoming prompts against security rules, blocking those matching high-severity security or jailbreak patterns while authorizing safe prompts.

Catalyst puts a governance layer between AI agents and consequential actions. Before your agent writes files, sends messages, deploys code, or calls external APIs, it checks in with Catalyst. Depending on your policy, actions are allowed immediately, routed to a human for approval, or denied. Includes 8 pre-built compliance framework packs (GDPR, SOC 2, ISO 27001, HIPAA, PCI-DSS, EU AI Act, Briber

Prevents autonomous agents from fabricating tool results by verifying HMAC-signed receipts against epistemic claim types, forcing re-grounding or escalation before actions commit.

Enables querying the abuse.ch MalwareBazaar database for malware samples by tag, family, signature, or recent submissions.

A safety guard for AI assistants that inspects actions (file reads, queries, etc.) and classifies them as SAFE, SUSPICIOUS, or BLOCK with explanations, using both known-attack patterns and behavior-based zero-day detection.

A comprehensive MCP server that provides AI assistants with professional-grade network analysis capabilities, combining Wireshark packet analysis, nmap scanning, and threat intelligence for enhanced network troubleshooting and security analysis.

Enables email validation and domain checking to detect disposable or temporary email addresses via the Disify API, providing formatting, DNS, risk flags, and classification.

Enables MCP-capable runtimes to read agent message rooms, sign and post public messages, and create or verify Ed25519 contribution proofs for Technocore.
