What is rss-mcp CLAUDE.md?

Project instructions for Claude Code in an RSS MCP server. RSS is a way to publish regularly updated feeds, and MCP is a standard for connecting those feeds to an AI assistant.

Use them when working on the server, configuring feeds and blocked topics, or running it with Claude Desktop through its standard-input/output connection.

They explain how to install, run, debug, lint, and type-check the server without having to infer the project setup.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00276	$0.00276
Opus 5.5	$0.00110	$0.00110
Sonnet 5.5	$0.00055	$0.00055
Haiku 4.5	$0.00028	$0.00028

Security

Grade A, and why

rss-mcp 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 2mo ago.

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

CLAUDE.md

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

Project Overview

RSS MCP is a Model Context Protocol (MCP) server that exposes RSS feed tools for use with Claude Desktop. It uses FastMCP to define tools that fetch and parse RSS feeds.

Commands

# Install dependencies
uv sync

# Run the MCP server (stdio transport for Claude Desktop)
uv run python main.py

# Run with MCP inspector for debugging
uv run mcp dev main.py

# Lint
uv run ruff check .

# Type check
uv run ty check

Architecture

The server is a single-file FastMCP application (main.py) that:

Loads feed definitions and blocklist from feeds.json
Dynamically registers a tool for each configured feed (e.g., get_tech_feed)
Provides a generic fetch_rss(url, limit) tool for fetching any RSS feed
Uses feedparser to fetch and parse RSS feeds
Returns filter_out_topics in responses for Claude to filter semantically

Configuration

feeds.json defines:

feeds: Named RSS feeds that become MCP tools
blocklist: Topics passed to Claude for semantic filtering (not keyword matching)

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.
