AI Security Agents for Code Review

pi-hosts is an MCP-style utility that gives the Pi coding agent structured, safer access to servers through named SSH targets. Instead of forcing an agent to rediscover hostnames, SSH syntax, OS details, package managers, service managers, or Docker status each time, pi-hosts exposes typed host tools with target resolution, cached facts, command risk checks, connection reuse, and JSONL audit logs. It is built for developers and operators who already use Pi for coding or infrastructure assistance and want remote server workflows to be faster, more repeatable, and easier to inspect. The recent Show HN launch makes it relevant to the growing ecosystem of agent-specific infrastructure tools around SSH, operations, and guarded execution.

StateSpace is a search engine for the agentic web, focused on discovering llms.txt-enabled sites and resources that AI agents can understand and use. The homepage advertises a web search interface plus a CLI, SDK, and MCP server on GitHub, so it is aimed at developers, AI builders, and agent workflow designers who need structured discovery rather than another general web search box. It solves a growing problem: as more websites publish machine-readable context for LLMs, builders need a way to find, query, and integrate those sources into tools. The Show HN launch framed it specifically as a search engine for llms.txt sites, and the official page backs that with product links to GitHub, Discord, npm, and X.

OpenRouter is a unified API platform that gives developers access to many leading AI models through one endpoint, making it easier to compare providers, manage fallbacks, and route traffic without rebuilding integrations each time. Teams can use it to prototype faster, optimize model cost and quality, and keep application logic more portable across model vendors. It is especially useful for startups, AI product teams, developers, and experiment-heavy builders who want flexibility when working with multiple frontier and open models. What makes OpenRouter stand out is its model marketplace approach combined with practical routing and compatibility features, letting users treat model access as an interchangeable layer instead of getting locked into one provider from the start.
