AGENTS.md

mcp-server-manager AGENTS.md is an instructions file for Codex, OpenCode from sardine-ai/mcp-server-manager. It costs 2,952 tokens per session, scanned B, original, MIT.

Project instructions for MCP Server Manager, a command-line and interactive tool for managing Model Context Protocol servers across AI clients.

In plain words
What is it for?
They help develop, run, type-check, lint, and reload the TypeScript project, while managing MCP server connections for tools such as Codex, Cursor, Windsurf, and VS Code.
Why use it?
They explain how the project connects clients through one local gateway and how contributors should build and check changes.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads ~/.codex paths; mentions AGENTS.md; mentions Codex.

This is sardine-ai/mcp-server-manager's own configuration. It tells Codex and OpenCode how to work on mcp-server-manager itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server-manager configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

mcp-server-manager AGENTS.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Project Overview

MCP Server Manager (mcpsm) is a CLI tool for managing MCP (Model Context Protocol) servers across multiple AI clients (Codex Desktop, Cursor, Windsurf, VS Code, etc.). It provides both an interactive TUI and CLI commands for server management, testing, client syncing, and daemon control.

Client Connection Model

The system uses a gateway pattern for client connections:

  • A single mcpsm server is added to each connected client's configuration
  • This server uses supergateway to proxy all MCP requests to the daemon on localhost:{port}/mcp
  • When the port setting is changed, all connected clients are automatically updated
  • Supports real-time config loading for clients without restart (Cursor, Windsurf, VS Code)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
