mcp-httpserver-proxy: Skill for Claude Code

.agents/skills/mock-sse-server/SKILL.md

mock-sse-server is a skill for Claude Code, Codex from shailesh17/mcp-httpserver-proxy. It costs 29 tokens per session (200 once invoked), scanned A, original, MIT.

A local fake server that communicates with MCP clients over HTTP and SSE, a web connection that can send live events. It is designed to test the mcp-httpserver-proxy connection from end to end.

In plain words
What is it for?
Use it to start a test MCP endpoint, connect the proxy to it, and verify that the proxy connects and forwards messages correctly.
Why use it?
It lets you test the proxy without relying on a real remote MCP service. This makes connection and message-forwarding problems easier to reproduce locally.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is shailesh17/mcp-httpserver-proxy's own configuration. It tells Claude Code and Codex 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 →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node dist/index.js http://127.0.0.1:8123/sse.

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

mock-sse-server 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/mock-server.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Mock SSE MCP Server

Use this skill when you want to verify that mcp-httpserver-proxy connects properly to an HTTP/SSE MCP endpoint and forwards messages.

Quick Start

  1. Start the mock SSE server:

    node .agents/skills/mock-sse-server/scripts/mock-server.js

    This will listen on http://127.0.0.1:8123/sse.

  2. In another terminal, test the proxy against the mock server:

    node dist/index.js http://127.0.0.1:8123/sse

  3. The proxy should output Proxy running. Connected to http://127.0.0.1:8123/sse on stderr.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
