mcp-httpserver-proxy: Instructions file for Codex

AGENTS.md

mcp-httpserver-proxy AGENTS.md is an instructions file for Codex, OpenCode from shailesh17/mcp-httpserver-proxy. It costs 861 tokens per session, scanned A, original, MIT.

Repository instructions for a Node.js and TypeScript bridge between an MCP client and an MCP server. It converts HTTP connections using Server-Sent Events into stdio messages, which desktop clients can read.

In plain words
What is it for?
Use them when changing the proxy’s entry point, transport lifecycle, logging, or client compatibility, and when verifying that the compiled command-line program works.
Why use it?
They protect the JSON message stream from accidental log output and specify the required order for starting and managing both connections.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is shailesh17/mcp-httpserver-proxy's own configuration. It tells Codex and OpenCode how to work on mcp-httpserver-proxy 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-httpserver-proxy 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 A, and why

mcp-httpserver-proxy AGENTS.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 2mo 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.

Agent Guidelines for mcp-httpserver-proxy

Welcome, AI agent! This document details the technical architecture, development workflows, strict constraints, coding standards, and Pull Request procedures for this repository.

🎯 Repository Overview

mcp-httpserver-proxy is a transparent bridge between:

  1. An MCP Client communicating over stdio (StdioServerTransport from @modelcontextprotocol/sdk).
  2. An MCP HTTP Server communicating over Server-Sent Events (SSEClientTransport from @modelcontextprotocol/sdk).

The primary entry point is src/index.ts, which compiles to dist/index.js as an executable Node.js CLI.

⚠️ Critical Constraints & Rules

1. Standard Output (stdout) is Sacred

[!IMPORTANT] NEVER use console.log() or write arbitrary text to process.stdout! The client (Claude Desktop, Cursor, etc.) parses stdout strictly as JSON-RPC Model Context Protocol messages. Any non-protocol output on stdout will corrupt the transport and crash the client session.

All logging, informational messages, and diagnostics MUST be routed to process.stderr via console.error().

2. Transport Lifecycle Order

  • The proxy must establish and confirm the SSE backend connection (sseTransport.start()) before starting stdioTransport.start().
  • If the SSE backend fails or closes, the proxy must gracefully exit or signal failure without leaving orphaned stdio loops.
  • Handle process termination signals (SIGINT, SIGTERM) to clean up open transport connections.

3. Package Management & Tooling

  • Always use pnpm as the package manager (pnpm install, pnpm run build, pnpm run format, pnpm run check).
  • Never introduce npm or yarn lockfiles.
  • Standard formatting and linting is managed by Trunk:
    • Format: pnpm run format (trunk fmt)
    • Lint/Check: pnpm run check (trunk check)

4. Git & Commit Standards

  • All commit messages and PR titles must follow Conventional Commits:
    • Format: <type>(<scope>): <description>
    • Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert.
  • Commits are verified locally via Trunk git hooks (commitlint).
  • PR titles are verified in CI via GitHub Actions (semantic-pr.yml).

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.
