Aelios: MCP server, setup and security
Aelios is an open-source MCP server published on GitHub that lets an AI agent capture conversations and recall consolidated memories across multiple AI clients. Its repository has 138 stars and its last commit is from October 23, 2026 and it is licensed under AGPL-3.0.
What Aelios does
According to its repository: “Self-hosted long-term memory gateway for AI clients: runs on your own Cloudflare account (Workers + D1 + Vectorize), captures conversations, consolidates them overnight, and recalls them across Chatbox, Claude Code, and Codex via API or MCP tools.”
The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Aelios is listed under Memory and knowledge, a category of 250 servers in the directory, where it ranks #65 by stars.
Topics declared by the repository: ai-memory, cloudflare-workers, d1, long-term-memory, vectorize.
Installing and connecting Aelios
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.
Security: what to check
Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Aelios. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on March 7, 2026, the wusaki0723/Aelios repository has 138 stars and 90 forks, with 0 open issues. It has more stars than 72% of the servers in the directory. It received changes this month.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
