Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project Overview

RivalSearchMCP is an MCP server providing 9 specialized tools for web research, content discovery, and analysis. Built on FastMCP, it offers multi-engine search (Yahoo/DuckDuckGo), website traversal, scientific research, and AI-enhanced research workflows. Ships with Claude Code Agent Skills for standalone CLI usage.

- **100% free**: No API keys required for core functionality
- **Dual deployment**: Hosted service at `https://RivalSearchMCP.fastmcp.app/mcp` or local development
- **Transport modes**: stdio (default, for CLI/IDE) or HTTP (production via `ENVIRONMENT=production`)

## Development Commands

The project uses [uv](https://docs.astral.sh/uv/) for dependency management and the [`fastmcp`](https://gofastmcp.com) CLI for running the server. Configuration lives in `fastmcp.json` (source / environment / deployment) and `pyproject.toml`.

### Setup & Running
```bash
# Install all dependencies (prod + dev) into a uv-managed venv
uv sync --extra dev

# Set up pre-commit hooks
uv run pre-commit install

# Run server (auto-detects fastmcp.json)
…

How to install

The exact contents, by fingerprint
mdr add damionrashford/rivalsearchmcp/CLAUDE.md@sha256:1f9b30f839fb79a0

The line at the top of this page pins the label git:20260527.df76525, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
