Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00515 | $0.00515 |
| Opus 5 | $0.00258 | $0.00258 |
| Sonnet 5 | $0.00103 | $0.00103 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
mcp-httpserver-proxy CLAUDE.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.
How it starts
The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Guidelines for mcp-httpserver-proxy
Welcome, Claude! This document details the technical architecture, strict constraints, development workflows, and Pull Request procedures for mcp-httpserver-proxy.
⚠️ Critical Constraint: Sacred Standard Output (stdout)
[!IMPORTANT] NEVER use
console.log()or write arbitrary text toprocess.stdout! The client (Claude Desktop, Cursor, etc.) parsesstdoutstrictly as JSON-RPC Model Context Protocol messages. Any non-protocol output onstdoutwill corrupt the transport and crash the client session.All logging, informational messages, and diagnostics MUST be routed to
process.stderrviaconsole.error().
🛠️ Common Commands
- Build:
pnpm run build(tsc) - Test:
pnpm test(node --test test/**/*.test.ts) - Format:
pnpm run format(trunk fmt) - Lint & Static Analysis:
pnpm run check(trunk check) - Dev Watch Mode:
pnpm run dev
🏗️ Architecture & Transports
- Transport Bridge: Transparently connects an MCP Client over
stdio(StdioServerTransport) to an MCP HTTP Server over Server-Sent Events (SSEClientTransport). - Transport Lifecycle Order: Establish and confirm the SSE backend connection (
sseTransport.start()) before startingstdioTransport.start(). - Custom HTTP Headers: Configured via repeated
-H/--headerflags andMCP_PROXY_HEADERSenvironment variable. - Resilient Connection Retries: Configured via
--retries(-r) and--retry-delay(-d) with exponential backoff.
📝 Coding & Commit Standards
- Conventional Commits: All commit messages and PR titles must follow
<type>(<scope>): <description>(e.g.feat(cli): add header flag,docs(claude): add CLAUDE.md). - Pre-flight Checks: Always run
pnpm test,pnpm run format, andpnpm run checkbefore submitting. - Dependency Management: Use
pnpmexclusively. Never introducenpmoryarnlockfiles.
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.

mcp-httpserver-proxy CLAUDE.md is an instructions file published in the GitHub repository shailesh17/mcp-httpserver-proxy (2 stars, last pushed 9d ago), licensed MIT. It adds 515 tokens to every session, about $0.0026 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
