### Description (declared)

# shutup-mcp

> Experimental MCP tool-list filtering proxy for large tool catalogs.

`shutup-mcp` sits between an MCP client and one or more MCP servers. It aggregates tool definitions and exposes only the top-k tools that match the current intent.

This repository is an **alpha implementation seed**. It is useful for experimenting with tool-list compression, but it is not yet a full production MCP gateway.

---

## What It Does

- Reads a Claude Desktop-style MCP config.
- Discovers configured MCP servers.
- Fetches and prefixes upstream tools.
- Builds a hybrid retrieval index over tool names and descriptions.
- Filters `tools/list` results using:
  - explicit CLI intent;
  - a runtime `shutup__set_intent` tool;
  - fallback behavior when no intent is known.
- Routes `tools/call` to the correct upstream server.
- Supports local embedding backends:
  - `sentence-transformers`;
  - `ollama`.

---

## What It Does Not Yet Do

This alpha does not yet provide:

- full MCP request proxying for every capability;
- persistent upstream sessions for every server;
- guaranteed client-side dynamic intent detection across all MCP clients;
- production authentication or sandboxing;
- benchmark-backed token or latency claims.

Earlier README versions included strong reduction metrics. Those are removed until reproducible benchmarks are added.

## Install

```bash
pip install shutup-mcp
```

For local development:

```bash
pip install -e ".[dev]"
```

---

## CLI Usage

### One-shot tool filtering

```bash
shutup \
  --config ~/Library/Application\ Support/Claude/claude_desktop_config.json \
  --intent "read and write local files" \
  --top-k 5
```

This prints a JSON array of filtered tool definitions.

### Run as MCP proxy

```bash
shutup \
  --config ~/Library/Application\ Support/Claude/claude_desktop_config.json \
  --intent "work with GitHub issues" \
  --serve \
  --top-k 5
```

If `--intent` is supplied, `tools/list` returns only top-k tools matching that intent.
