"An MCP to access OpenAI's RAG system via API" matching MCP servers:

Self-hosted credential store and API proxy for AI agents. One Bearer token, all your services. Handles OAuth refresh, encrypted storage, audit logging, and per-agent permissioning.

This MCP server enables interaction with Google's Verified Access API, allowing users to verify the security posture of Chrome OS and Chrome Browser devices through natural language commands.

An MCP server that provides access to Google's Access Context Manager API, enabling management of service perimeters and access levels through natural language.

Enables AI agents to interact with Nextcloud files only through human-approved, time-limited grants, with mandatory audit logging and no standing content access.

Enables AI agents to interact with Home Assistant through tiered, human-gated access: free reads and reversible comfort controls, while sensitive actions like locks, alarm, covers, and climate changes require per-operation human approval via Matrix.

Enables AI agents to securely read from and interact with Matrix and Microsoft Teams chat under scoped, expiring, human-approved grants, with per-operation approval for sending and editing messages and no free access to room content.

Enables secure remote MCP server connections using Cloudflare Access OAuth, with user-authenticated tools on Cloudflare Workers.

A remote MCP server with built-in Access OAuth, enabling authenticated MCP connections via Cloudflare Access and conditional tool permissions.

Enables remote MCP server with OAuth authentication using Cloudflare Access, allowing users to connect via sign-in with an identity provider.

A remote MCP server with Cloudflare Access OAuth authentication, deployable to Cloudflare Workers, enabling secure connections from MCP clients with identity-based access control.

MCP server that integrates Apache Ranger authorization with RAG, enforcing Ranger policies to control access to knowledge bases before forwarding queries to RAG Studio.

Governance framework for LLM agents. Exposes seven mechanically-enforced rules plus tools for preflight file protection, audit-chain verification, session handoff and worklog templates, MCP config auditing, and an emergency kill switch.

A community MCP server for Cisco Secure Access that exposes the Secure Access REST API to AI clients as a curated catalog of tools for Admin, Deployments, Investigate, Policies, and Reports.

Enables analysis of normalized scan findings as immune signals to discover co-occurring fleet threat patterns, synthesize non-executing defensive recipes, recall successful outcomes, and plan adjacent-cohort targeting via MCP tools.

Enables AI agents to investigate threats, pull reports, manage security policies, and administer deployment infrastructure through the Cisco Secure Access REST API.

Enables remote MCP connections with Cloudflare Access OAuth, providing tools like add and generateImage with user-based access control.

An MCP server protected by Cloudflare Access as a self-hosted application, validating Access JWT and conditionally exposing tools based on user identity.

Enables remote MCP connections with Cloudflare Access OAuth authentication, providing tools like add and restricted image generation.

A Cloudflare Workers-based MCP server that enables secure remote connections using built-in OAuth authentication via Cloudflare Access. It provides identity-based access control for MCP tools and supports persistent state management through Durable Objects and SSE.

An MCP server providing risk-aware API governance tools for AI agents. Agents call preflight checks before tool calls or merges to verify API contracts are safe. Returns risk score, blast radius, agent impact, economic cost, and a deterministic ALLOW/WARN/REQUIRE_APPROVAL/BLOCK decision. MCP endpoint: https://app.coderifts.com/mcp
