claude-context
Code search MCP for Claude Code. Make entire codebase the context for any coding agent.
Claude Code doesn't do anything with semantic search or embeddings out of the box. They use a simple grep tool instead.
Neither does OpenAI's Codex CLI - you can confirm that by looking at the source code https://github.com/openai/codex
Cursor and Windsurf both use semantic search via embeddings.
You can get semantic search in Claude Code using this unofficial plugin: https://github.com/zilliztech/claude-context

orama
🌌 A complete search engine and RAG pipeline in your browser, server or edge network with support for full-text, vector, and hybrid search in less than 2kb.
Project mention: Building KiroGraph: a 100% local semantic code knowledge graph for Kiro | dev.to | 2026-04-08Orama does something clever: hybrid search. One query combines full-text relevance and vector similarity, which produces better results than running them separately and merging. Pure JS, no native compilation. If you want the best result quality and no native dependencies, Orama is the choice.
-
genkit
Open-source framework for building AI-powered apps in JavaScript, Go, and Python, built and used in production by Google
Project mention: Genkit Middleware: Intercept, Extend and Harden your Gen AI Pipelines | dev.to | 2026-05-14For more inspiration, the source of the official middlewares is open in the Genkit GitHub repository, and reading them is genuinely educational.
-
OpenMemory
Local persistent memory store for LLM applications including claude desktop, github copilot, codex, antigravity, etc.
Project mention: Show HN: A local-first memory store for LLM agents (SQLite) | news.ycombinator.com | 2025-12-14edit:
from gpt5.2 with prompt:
<< 'adversarial review request. please look at the github link for signs of being written by llm ( extra points if you can point to the llm that generated it ) https://github.com/CaviraOSS/OpenMemory'
>> I can’t prove it’s LLM-written from the outside, but the README (at least) has a lot of “LLM smell.” I’d put it at high likelihood of AI-assisted marketing/docs copy, with some sections bordering on “generated then lightly edited.”
but then it adds a list of style reason why it could be generated by llm
<< “Extra points”: which LLM wrote it?
Most likely: Claude 3.5 Sonnet–style output
<< if i were to point to comments in readme and code, what would you say upon re-review
>> Comments that narrate the obvious (especially line-by-line)

vector-storage
Vector Storage is a vector database that enables semantic similarity searches on text documents in the browser's local storage. It uses OpenAI embeddings to convert documents into vectors and allows searching for similar documents based on cosine similarity.
