Claude Context is an MCP (Model Context Protocol) server built by Zilliz—the company behind the Milvus vector database—that solves one of the most annoying problems in AI-assisted development: context window fragmentation. Instead of manually feeding Claude Code snippets of your codebase, Claude Context indexes your entire repo as a vector database and makes it semantically searchable on demand. The tool hooks into Claude Code via MCP, so when you ask Claude to "fix the auth middleware bug," it can automatically retrieve the relevant files, function signatures, and related tests—rather than asking you to paste them in. Zilliz is leaning into their vector DB expertise here: the search is dense embedding-based, not keyword-based, which means it finds conceptually related code even when the variable names don't match. With 6,199 GitHub stars and TypeScript-first implementation, it's already picking up serious developer interest. The main caveat is dependency on Zilliz's infrastructure for the embedding layer, though the repo appears to support local embedding options too. For teams working on large codebases with Claude Code, this is potentially a workflow-changer.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.
Reviewer scorecard
“This is the missing piece for Claude Code on large repos. I've been pasting files manually like a caveman—having semantic vector search as an MCP server means the model always has the right context without me playing file manager.”
“The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.”
“Zilliz isn't doing this out of the goodness of their hearts—they want you on Milvus Cloud. The local embedding path works but requires running your own vector DB, which adds ops burden. Also, 'make the whole codebase context' can actually hurt model performance on tightly scoped tasks.”
“It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.”
“MCP is becoming the API layer of the agentic era, and tools like this prove it. When coding agents have persistent, semantic memory of your entire codebase, the concept of 'asking the model to understand your code' becomes irrelevant—it already does.”
“As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.”
“As someone who documents and demos developer tools, this removes so much friction from setup tutorials. Claude can now reference the actual project structure without me manually constructing context every time.”
“Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.”
