What is xiaozhi-mcphub copilot-instructions.md?

Project instructions for MCPHub, a TypeScript service that manages and provides unified access to multiple MCP servers. MCP servers are programs that expose tools or data to an AI agent.

Use them when changing MCPHub's backend, frontend, MCP connections, HTTP routes, configuration, or translations.

They explain the project's structure, development commands, module format, configuration, endpoints, and coding conventions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00402	$0.00402
Opus 5	$0.00201	$0.00201
Sonnet 5	$0.00080	$0.00080
Haiku 4.5	$0.00040	$0.00040

Security

Grade A, and why

xiaozhi-mcphub copilot-instructions.md scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to MCP-Server copilot-instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

MCPHub Coding Instructions

Project Overview

MCPHub is a TypeScript/Node.js MCP server management hub that provides unified access through HTTP endpoints.

Core Components:

Backend: Express.js + TypeScript + ESM (src/server.ts)
Frontend: React/Vite + Tailwind CSS (frontend/)
MCP Integration: Connects multiple MCP servers (src/services/mcpService.ts)

Development Environment

pnpm install
pnpm dev           # Start both backend and frontend
pnpm backend:dev   # Backend only
pnpm frontend:dev  # Frontend only

Project Conventions

File Structure

src/services/ - Core business logic
src/controllers/ - HTTP request handlers
src/types/index.ts - TypeScript type definitions
src/config/index.ts - Configuration management

Key Notes

Use ESM modules: Import with .js extensions, not .ts
Configuration file: mcp_settings.json
Endpoint formats: /mcp/{group|server} and /mcp/$smart
All code comments must be written in English
Frontend uses i18n with resource files in locales/ folder
Server-side code should use appropriate abstraction layers for extensibility and replaceability

Development Process

For complex features, implement step by step and wait for confirmation before proceeding to the next step
After implementing features, no separate summary documentation is needed - update README.md and README.zh.md as appropriate

Development Entry Points

MCP Servers: Modify src/services/mcpService.ts
API Endpoints: Add routes in src/routes/, controllers in src/controllers/
Frontend Features: Start from frontend/src/pages/
Testing: Follow existing patterns in tests/

Changes

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.
