Overview

Description from the maker (original English)

Local read-only repository context retrieval for AI coding agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Download the maker’s .mcpb file

The link goes to the maker’s own file; we do not host or repackage it. Open the file and Claude Desktop installs it.

Run this in your terminal

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Sippion safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

Sippion

English | 日本語

Use less AI context. Make API tokens — and subscription usage allowances — last longer.

Sippion is a local, read-only MCP server that helps AI coding agents consume fewer tokens. Instead of letting an agent open large parts of a repository, Sippion's single tool, repo_context, returns a small set of relevant, bounded source excerpts first.

This reduces unnecessary context per task. It can lower usage for API-based workflows, but that is not the only benefit: Sippion can also help subscription-based AI coding plans last longer by reducing how much context the agent needs to consume.

How it works

AI coding agent

↓ ask for focused repository context Sippion repo_context ↓ return a few relevant excerpts AI reads only the files it actually needs

Example:

repo_context {"q":"authentication token validation"}

Sippion uses bounded lexical, structural, and semantic retrieval while staying local and read-only.

Install

macOS / Linux
curl -fsSL --proto '=https' --proto-redir '=https' --tlsv1.2 https://raw.githubusercontent.com/Sitten-Tokyo/Sippion/75d6b27e83b86bec00297cd5b5c05bb014e16904/scripts/bootstrap.sh | sh
Windows PowerShell
irm https://raw.githubusercontent.com/Sitten-Tokyo/Sippion/75d6b27e83b86bec00297cd5b5c05bb014e16904/scripts/bootstrap.ps1 | iex

Then restart your AI client. sippion setup registers Sippion for Codex, Claude Code, Antigravity, and OpenCode.

Useful commands:

sippion setup

sippion doctor sippion uninstall sippion mcp --root-auto

Why Sippion

  • Fewer tokens: gives the agent focused repository context instead of broad file reads.
  • Useful beyond API billing: can help subscription usage allowances last longer too.
  • Local and private: no network access while serving repository context.
  • Read-only: never modifies the repository or executes repository code.
  • No persistent index: retrieval state stays in RAM.
  • Small surface area: one MCP tool, repo_context.

Sippion is a repository-context tool, not a compiler or language server. Structural parsing currently covers Rust, Python, JavaScript/TypeScript, Go, Java, C#, C, and C++.

Safety

Sippion does not run repository code, build scripts, compilers, LSP servers, or shell commands during retrieval. Repository text is treated as untrusted data, and high-confidence secrets are redacted before model output.
