AISIX AI Gatewayofficial
AlicenseAqualityAmaintenanceSelf-hosted MCP gateway that registers upstream MCP servers and fronts them behind one governed Streamable HTTP endpoint: per-tool access control by caller API key, guardrails over tool arguments and results, rate limits, and usage logs. The same Rust gateway also proxies LLM and A2A agent traffic.21152Apache 2.0Why this server?
Provides an integration for OpenAI Agents, allowing AI agents to send and receive emails via Dead Simple Email.
AlicenseAqualityFmaintenanceProvides AI agents with real email infrastructure, enabling them to create inboxes, send/receive messages, and extract verification codes from incoming mail.14MITWhy this server?
Provides persistent, encrypted, local-first memory for OpenAI Codex agents, enabling them to retain context across sessions.
AlicenseAqualityBmaintenanceA tiny MCP server that wraps Perseus Vault to provide persistent, encrypted, local-first memory for OpenAI Codex agents, enabling them to remember project conventions, decisions, and context across sessions.5MITWhy this server?
Supports ChatGPT's Deep Research feature with a simplified interface for searching WordPress Trac data and fetching detailed information about tickets and changesets.
AlicenseAqualityAmaintenanceA Model Context Protocol server that provides AI assistants with comprehensive access to WordPress.org Trac data, enabling intelligent queries about WordPress development, ticket tracking, and code changes.515GPL 2.0Why this server?
