Mellos mapping: MCP server, setup and security
Mellos mapping is an open-source MCP server published on GitHub that lets an AI agent draw live layered dependency maps in a terminal pane during development. Its repository has 115 stars and its last commit is from October 13, 2026 and it is licensed under MIT.
What Mellos mapping does
According to its repository: “Live layered dependency map for bottom-up development, drawn by the agent in a terminal pane.”
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. Mellos mapping is listed under Coding agents, a category of 151 servers in the directory, where it ranks #76 by stars.
Topics declared by the repository: bottom-up, claude-code, codex, dependency-graph, developer-tools, terminal.
Installing and connecting Mellos mapping
Distribution modes declared in the official MCP registry:
- npm package (Node.js, usually started with
npx)
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 Mellos mapping. 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 12, 2026, the GuangminJu/mellos-mapping repository has 115 stars and 9 forks, with 0 open issues. It has more stars than 69% of the servers in the directory. It received changes this month. Version published in the registry: 0.28.0 (October 13, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
