HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · README.md
A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.
- Decode the base64 string and confirm it is not an instruction directed at the agent.
- Move any legitimate binary or signature data into a dedicated file (
*.sig,SIGNATURES) outside the documentation.

RIPE Atlas MCP Server
A Model Context Protocol (MCP) server for the RIPE Atlas network measurement platform. Enables AI assistants to create network measurements, retrieve results, search probes, and manage credits.
Features
- All 6 measurement types: ping, traceroute, DNS, TLS/SSL, HTTP, NTP
- Flexible probe selection: by country, ASN, prefix, geographic area, specific probes, or tags
- Rich result retrieval: time-range filtering, probe filtering, latest-only mode
- Dual output format: JSON (structured) and Markdown (human-readable)
- Probe discovery: search 12,000+ probes worldwide by location, network, status
- Credit management: check balance and usage statistics
Quick Start
Using npx (recommended)
npx ripe-atlas-mcp-serverInstall globally
npm install -g ripe-atlas-mcp-serverConfiguration
Prerequisites
- Create a free account at atlas.ripe.net
- Create an API key at atlas.ripe.net/keys/ with "Create measurements" permission
- Set the environment variable:
export RIPE_ATLAS_API_KEY=your_key_here
Note: Read-only operations (listing measurements, searching probes) work without an API key. Creating measurements requires an API key.

Check DNS propagation:
"Do a DNS lookup for example.com AAAA records from 50 probes across the world"
Find probes in a country:

Trace a route:
"Run a traceroute to 8.8.8.8 from 5 probes in Germany using ICMP"
What is RIPE Atlas?
RIPE Atlas is a global Internet measurement network operated by RIPE NCC. It consists of thousands of hardware and software probes hosted by volunteers worldwide. Users can run network measurements (ping, traceroute, DNS, TLS, HTTP, NTP) from these distributed vantage points, providing visibility into Internet routing, performance, and DNS resolution globally.
