    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.

    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.

    Umami Analytics has an MCP now

    Umami Analytics now supports the Model Context Protocol (MCP), allowing AI agents to query website analytics through natural language instead of accessing dashboards directly. The read-only connection uses Umami Cloud API and requires an API key for authentication, compatible with MCP-enabled AI clients like Claude Desktop and Cursor.

    Certify the Conversation, Not Just the AI Agent

    Multisynapse released features to improve agent certification by making decisions more traceable and expanding evaluation beyond single turns. Runs now carry diagnoses explaining policy decisions and refusals, conversations are certified as complete units rather than individual turns, and coding agents are subject to governance controls when operating through the platform.

    Should you read the code, is RAG dead, and did Skills kill MCP?

    The article examines four popular AI hot takes in software development, arguing that nuance matters more than confidence. It explains that developers should review AI-generated code based on risk level, that AI competence is becoming a job skill rather than a requirement, that Skills and MCP serve complementary purposes, and that RAG remains valuable despite reduced hype.
