Relayer MCP: MCP server, setup and security
Relayer MCP is an open-source MCP server that lets an AI agent install and manage self-hosted decentralized S3-compatible object storage infrastructure. Its repository has 3 stars and its last commit is from October 8, 2026 and it is licensed under Apache-2.0.
What Relayer MCP does
According to its repository: “Install and manage a self-hosted XNS Relayer, S3-compatible object storage on a decentralized provider network: setup, health, configuration and backups.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Relayer MCP is listed under Cloud platforms, a category of 116 servers in the directory, where it ranks #102 by stars.
Topics declared by the repository: agentic-workflows, ai-agents, claude, cloud-storage, docker, object-storage.
Installing and connecting Relayer MCP
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript. Listed systems: macOS, Windows, Linux.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Relayer MCP. 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 August 8, 2026, the xns-cloud/relayer-mcp repository has 3 stars and 0 forks, with 0 open issues. It has more stars than 8% 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.
