"Open Collective" matching MCP servers:

Open-source permission control plane for AI agents — scan, enforce, and audit every tool call with code-level policies that prompt injection can't bypass.

CyberSecurity MCP Server extends Claude with real-time cybersecurity reconnaissance capabilities that Claude doesn't have by default. Instead of manually running 5 different tools across different terminals, just tell Claude "analyze google.com" and get a complete security breakdown instantly. Tools included: * WHOIS Lookup — registrar, ownership, creation/expiry dates * DNS Enumeration — A,

Enables AI-driven open-source intelligence investigations by exposing 30 tools for scanning emails, usernames, domains, IPs, and more, with real subprocess execution.

Open-source guardrails between AI agents and FHIR clinical data — PHI redaction, immutable audit, step-up auth, tenant isolation. MCP server + OpenAI/Gemini adapters. A healthclaw.io project.

Security-focused MCP server for TP-Link Omada Open API workflows, enabling network management via natural language.

Deterministic agentic data firewall that secures, monitors, and controls AI agent interactions with data and software via MCP, preventing data leaks.

Open-source MCP proxy that enforces security policies, content scanning, and audit logging between AI agents and tool servers

MCP server that verifies proof-bound consequential execution at the edge, acting as the open trust anchor for the Actenon ecosystem. It validates PCCB proofs without issuing grants or making policy decisions.

Open-source MCP servers that give AI agents structured access to networking standards, device databases, and security data.

Local, open-source multi-account MCP broker — one endpoint, every account. Add credentials once and switch identity without reconnecting, from any LLM client.

Enables agents to open production change dossiers, attach proof certificates, and request human approval through a secure, unforgeable gate—ensuring no irreversible change can proceed until it has been verified against a sandboxed shadow copy.

Connects your Bradescard account to AI assistants via Open Finance Brasil, enabling natural language queries about balances, statements, credit card bills, and investments in read-only mode.

An open-source MCP server that protects AI agents at runtime by evaluating every tool call against YAML policies and generating audit trails.

IntentFence is an open spend and action policy gate for autonomous AI that evaluates tool call constraints like scope, cost, data-retention, and approval, returning decisions such as safe_to_proceed, needs_review, or denied, and provides an MCP server endpoint at /mcp.

An open-source implementation of the Model Context Protocol (MCP) that bridges AI agents with enterprise systems, enabling secure access to real-world data and capabilities.

Real security scanners for AI coding agents — SAST (441 rules), secret detection (419+ patterns), dependency CVEs (OSV.dev), MCP/skill vetting, MITRE ATT&CK. Open-source, Rust, free

MCP server for querying Google's Open Source Vulnerabilities (OSV) database. Enables vulnerability lookups by package, version, commit, or ID using natural language via Pipeworx gateway.

Warden provides a trusted skill brain for open agents, enabling secure execution of curated, cryptographically-signed skills with sandboxing, trust scoring, and transparency logging, all with zero third-party dependencies.

Open-source AI governance toolkit — MCP servers & CLIs for scanning, auditing, and managing your AI environment

BrowseWeave enables MCP-compatible AI clients to control and read web pages already open in a real browser, providing semantic views and screenshots as needed.
