mcp-httpserver-proxy copilot-instructions.md

Editor instructions for a Node.js and TypeScript proxy that connects an MCP server over HTTP with desktop clients over stdio. Server-Sent Events (SSE) are a way for an HTTP server to send updates to a client.

In plain words
What is it for?
Use them when editing the proxy, choosing the package manager, formatting or checking code, and writing Conventional Commit messages.
Why use it?
They explain the project’s purpose and prevent ordinary log messages from being written into the strict JSON message channel used by clients such as Claude Desktop and Cursor.

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 A, and why

mcp-httpserver-proxy 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 yesterday.

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.

What it actually says

GitHub Copilot & Cursor Instructions

  • Project Purpose: mcp-httpserver-proxy is a Node.js TypeScript proxy that converts Model Context Protocol (MCP) HTTP/SSE connections to stdio for desktop clients like Claude Desktop and Cursor.
  • Stdio Integrity Rule: Never use console.log() to standard output. All logs and diagnostic output must go to console.error() (stderr) to prevent corrupting the JSON-RPC stdio transport.
  • Package Manager: Use pnpm.
  • Formatting & Linting: Use trunk fmt (pnpm run format) and trunk check (pnpm run check).
  • Commit Messages: Follow Conventional Commits format (feat:, fix:, docs:, chore:, etc.).

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.
