Lune
MCP server that grounds AI agents in full-text computer science papers from top-tier conferences, for students and researchers.
What Lune does
Lune is an MCP server that lets an AI agent search computer science papers from top-tier academic conferences. The homepage says it draws on A / A* conference papers and leaves out workshop, findings, tutorial, short, abstract and demo papers. The agent searches that collection and cites what it finds, rather than answering from memory or the open web.
According to the docs, paper results carry abstracts, authors, venue and publication metadata, citation relationships and stable source links. Full text reaches the agent when Lune has permission to index a paper. Lune also returns curated guidance for literature reviews, evaluation design, ablation studies, research writing, peer review and venue selection.
You can use it in three places. Lune Miniapps runs on luneresearch.com without setup. ChatGPT, Claude, Grok and other web chatbots can add Lune as a connector or plugin. Local MCP clients such as Claude Code, Cursor, VS Code and Codex connect to the hosted server at https://mcp.luneresearch.com (opens in a new tab), and the optional @retrograde-labs/lune-cli package (Node.js 22.12 or later) can write that configuration for you.
Usage is metered in requests. Most tool calls cost one request, batch tools charge per item, and the daily allowance resets at midnight UTC. The tool suits computer science students and researchers who already work with an AI assistant and want answers tied to published papers. The official pages do not describe coverage of fields outside computer science.
- Finding foundational and recent papers on a computer science topic from inside an AI chat
- Following what a paper cites and which later work cites it
- Checking a specific claim against indexed papers
- Getting guidance on evaluation design, ablation studies and research writing
Who should use it
- Computer science students and researchers who already use an AI assistant
- Developers running MCP clients such as Claude Code or Cursor who want paper citations in answers
Who should look elsewhere
- Research outside computer science, since the official pages describe only computer science conference papers
- Heavy use on the Free plan, which allows 10 requests a day
Strengths
- Limits sources to A / A* conference papers and excludes workshop and short papers
- Works inside existing AI apps through a hosted MCP endpoint, connectors and a CLI
- Free plan has no feature gates, only a daily request limit
- Privacy policy says queries are not used to train machine-learning models
Limitations
- Full text is available only when Lune has permission to index a paper
- Daily request caps of 10, 300 or 600 depending on plan, with credits needed beyond that
- No REST API is documented; the MCP server is the only programmatic interface described
- The CLI needs Node.js 22.12 or later
Privacy notes
Lune's privacy policy, operated by Retrograde Labs, says it does not sell personal information and does not train machine-learning models on your queries.

Agent Reach is a Python command-line tool that prepares an AI agent to read and search sites that are awkward to reach from a script, including Twitter/X, Reddit, YouTube, Bilibili, XiaoHongShu and GitHub. It leaves the actual reading to other tools. For each platform it picks an upstream project (Jina Reader for web pages, yt-dlp for YouTube, gh for GitHub, feedparser for RSS, twitter-cli and OpenCLI for social sites), installs it, checks that it works and gives the agent a SKILL.md file describing what to call. Every platform has an ordered list of backends, and when one breaks the maintainers move the next one up. The README cites June 2026, when Bilibili blocked yt-dlp and the tool switched to bili-cli. Running agent-reach doctor shows which channels work and which backend each is using. Web pages, YouTube, RSS, public GitHub repositories, V2EX and basic Bilibili search need no setup. Twitter, Reddit, XiaoHongShu, Facebook and Instagram need a logged-in session, either from cookies you export by hand or through OpenCLI reusing your desktop Chrome login. The main README is in Chinese; English, Japanese and Korean versions sit in the docs folder.

VoiceStudio is a desktop app that runs speech AI on your own computer: it clones and designs voices, generates speech from text, dubs videos, transcribes audio and has a dictation widget. The app is built on Electron with a Python backend. Its default speech engine is k2-fsa's OmniVoice, and the feature catalog lists more than a dozen alternatives, among them CosyVoice 3, KittenTTS, MLX-Audio and IndexTTS 2.5. Transcription defaults to WhisperX, with Faster-Whisper, Parakeet, Moonshine and others available. Models are downloaded when a workspace first needs them. The project says its tools cover 646 languages, a figure that also appears in the transcription tool of its MCP docs. Beyond the desktop workspaces, VoiceStudio exposes a local API and an MCP server on port 3900, so coding agents can generate speech, clone a voice or transcribe a file. The README states that local workflows stay on your hardware, remote workers are optional and usage analytics only run with consent. Version 0.5.3 was the last release built on Tauri; current releases are Electron only, and Tauri users have to install the new app separately.

Graphify turns a software project and related material into a queryable knowledge graph. It parses code locally with tree-sitter, connects structures such as calls, imports and inheritance, and writes the result to graph.json. It can also produce an interactive graph.html viewer and a GRAPHREPORT.md report. Queries can search the graph, explain a concept or trace a path between concepts. Code analysis does not require an LLM or API key. Graphify distinguishes relationships extracted directly from source from relationships resolved by Graphify. It does not use embeddings or a vector store for its graph. Documents, PDFs and images can join the same graph, but their semantic processing uses an AI assistant or configured model backend rather than the code-only parser. The project also supplies a skill that can be registered with supported coding assistants including Claude Code, Cursor, Codex and Gemini CLI.

ECC is an open-source system that adds reusable engineering workflows, skills, agents, memory, rules, hooks and security checks to coding agents. Its main path is Claude Code, with guided installation also available for Codex and Kimi Code. The repository also contains adapters for other coding agents, but the project warns that support is not equal across them. The current repository includes 68 agents, 293 skills and 94 legacy command shims. The supplied workflows cover tasks such as planning, testing, implementation, review, build repair, security and architecture. ECC also includes AgentShield integration for scanning agent configuration, prompts, hooks, MCP settings, permissions, secrets and related files. Hooks and memory can enforce checks outside the prompt, store session information and support its continuous-learning system. The easiest starting point is the ecc-universal guided installer. Claude Code setup needs Node.js 18 or newer, Git and Claude Code 2.1 or newer on PATH. The multi-agent installer can configure Claude Code, Codex and Kimi Code in one reviewed flow. Kimi installation is more limited: ECC writes managed project files but does not configure Kimi hooks, model or provider settings, or authentication.
