    Show HN: Which of your secrets did your coding agent send?

    Stroq is a security tool that monitors coding agents to detect when credentials or secrets are leaked to model providers and when untrusted content (like GitHub issues or dependency files) triggers dangerous commands. It analyzes session logs to identify which files or tool outputs originated injected instructions, blocking risky actions before they execute.

    MCP was always a bad idea?

    An article defends MCP (Model Context Protocol) as valuable for controlled agent deployments, arguing it remains essential for managing API access, authentication, and audit logging even as full-featured coding agents emerge. The author contends that dismissing MCP as obsolete overlooks its utility for building secure, user-friendly AI applications beyond unrestricted terminal agents.

    Belay – See what keeps going wrong in your Claude Code and Codex sessions

    Belay is a tool that analyzes Claude Code and Codex sessions saved on your machine, identifying repeated errors and failed patterns across coding runs. It groups problems like typecheck failures and infinite loops, then proposes fixes and rules for agents to review before implementation. The tool stores all data locally in an encrypted database without uploading anywhere, working offline with no account required.

    Giving My AI Agents Access to My RSS Reader

    A developer built Cove, a native Mac RSS reader that archives articles instead of maintaining an inbox, and added an MCP server to give AI agents access to its feeds and articles. The setup uses Tailscale to securely connect a remote agent running on a VM to Cove's local server, enabling automated daily digests of unread articles posted to Discord.

    Replacing Linear MCP with linear-CLI

    A developer replaced Linear's Model Context Protocol server with an unofficial CLI tool, reducing token usage by an estimated 5k-25k tokens per session. The CLI is more efficient because it returns only necessary fields by default, whereas the MCP server returns thirty-one fields including often-null SLA fields, and provides verbose responses for updates.

    Google Home MCP Server

    Google Home MCP Server enables AI-powered tools and virtual assistants to interact with smart home environments through standard MCP interfaces, allowing LLMs to inspect structures, monitor devices, and execute control actions. The service requires a Google Home Premium Advanced subscription, Google Cloud project setup, and OAuth configuration, with built-in safety protections like rate limits and restrictions on sensitive actions such as door unlocking.

    Show HN: I wrote the code and let an LLM review it

    A developer describes using an LLM as a mentor to learn MCP architecture by writing code themselves while the LLM reviews, plans, and guides—rather than generating code. The author emphasizes that hands-on coding builds deeper understanding than passive consumption of AI-generated output, and shares their approach of having Claude Opus create a structured learning plan for building an MCP server that downloads YouTube transcripts.

    Recursive Cognitive Optimization (RCO)

    Recursive Cognitive Optimization (RCO) is MCP-based middleware that coordinates multiple AI desktop applications like Claude Code and Codex to work together as a reasoning team, with one model proposing and another challenging while tools verify, all controlled by the user. The Windows application provides a visual dashboard for connecting desktop sessions and managing a shared queue, checkpoints, and evidence record without requiring additional API costs beyond existing subscriptions.

    Why MCP Was Always a Bad Idea

    An author argues that MCP, a protocol released by Anthropic in November 2024 to connect LLMs to external services, has become obsolete as language models have grown more capable and can now execute code, call APIs directly, and discover tools without needing MCP servers. The author suggests that most MCP servers should be replaced with direct terminal or HTTP API access, which are now more efficient for modern AI agents.
