What is my_mcp_rss CLAUDE.md?

Project instructions for an RSS-feed management server built with the Model Context Protocol. RSS is a format that lets applications collect updates from websites, while MCP standardises how AI clients use tools.

Working on the server’s TypeScript build, development watch mode, MCP inspection, Docker-based PostgreSQL setup, and environment configuration.

They give developers the commands and setup details needed to build, test, debug, and run the server with a PostgreSQL database.

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	$0.01167	$0.01167
Opus 5.5	$0.00467	$0.00467
Sonnet 5.5	$0.00233	$0.00233

Security

Grade A, and why

my_mcp_rss 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.

Project Overview

MCP RSS is a Model Context Protocol (MCP) server that provides RSS feed management capabilities through a standardized API. The server runs as a stdio-based MCP server that can be integrated with Claude Desktop and other MCP-compatible clients.

Development Commands

Build and Development

npm run build          # Compile TypeScript to JavaScript (outputs to dist/)
npm run watch          # Watch mode for development
npm run prepare        # Pre-publish build step (runs automatically)

Testing and Debugging

npx @modelcontextprotocol/inspector node dist/index.js    # Debug MCP server with inspector

Database Setup

Using Docker Compose (Recommended):

docker-compose up -d             # Start PostgreSQL in background
docker-compose down              # Stop PostgreSQL
docker-compose logs -f postgres  # View PostgreSQL logs

Using Docker CLI:

docker run -itd --name postgres-test -p 5433:5432 -e POSTGRES_USER=mcp_user -e POSTGRES_PASSWORD=123456 -e POSTGRES_DB=mcp_rss postgres:16-alpine

Configuration:

Copy .env.example to .env and customize settings
Docker Compose reads environment variables from .env file
Default credentials: mcp_user/123456 on port 5433 (change for production)

Architecture

Core Service Layer Pattern

The application follows a three-tier service architecture:

OpmlService (src/services/OpmlService.ts): Handles OPML file parsing and initial feed import
- Recursively processes OPML outline elements to handle nested categories
- Creates Feed entities from RSS subscriptions found in OPML
RssService (src/services/RssService.ts): Manages RSS feed fetching and article storage
- Uses rss-parser to fetch and parse RSS feeds
- Deduplicates articles by link before saving
- Runs on a cron schedule (configurable via RSS_UPDATE_INTERVAL)

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.
