fff.nvim (Freakin Fast Fuzzy File Finder) is a high-performance fuzzy search plugin for Neovim that takes the standard file-search experience and rebuilds it for the era of AI coding agents. Beyond fast fuzzy matching, it ships with a built-in MCP server that lets Claude Code, Codex, and other agents call it directly — reducing token waste from repeated file glob patterns and directory listings. The token-efficiency angle is the differentiator. Every time an AI agent needs to find a file, it typically burns tokens on recursive directory listings or blind glob patterns. fff.nvim's frecency scoring (blending frequency + recency) and git-status awareness mean the agent gets the most relevant files in the first response, not after three rounds of narrowing. Prebuilt binaries in Rust make cold-start negligible even on large repos. The plugin supports three grep modes — plain, regex, and fuzzy — plus multi-select, configurable thread counts, and telescope-compatible keybindings. It's currently trending on GitHub with 3,700+ stars after a weekend Show HN that focused heavily on the agent-aware angle. The MCP integration is the hook that makes this more than a Telescope/fzf replacement.

FoxGuard is a Rust-based security scanner designed to run at linter speed — sub-second full-project scans with zero cold-start overhead. Built on tree-sitter for real AST parsing (not regex heuristics), it covers 100+ security rules across 10 languages including Python, JavaScript, TypeScript, Go, Java, and Rust. Rules cover SQL injection, XSS, command injection, path traversal, hardcoded credentials, insecure deserialization, and more. Ships as a single native binary with no JVM or Python runtime dependency. FoxGuard is explicitly designed for the pre-commit and CI hook workflow that AI-generated code has made more important. With agents writing hundreds of lines per session, manual code review is increasingly the bottleneck — FoxGuard runs in the background on every save or commit and surfaces security anti-patterns before they hit a PR. The rule set is MIT-licensed and community-extensible via YAML definitions. For teams using AI coding agents, the "AI writes fast, security doesn't keep up" gap is real. FoxGuard positions itself as the fast-path answer: not a full SAST platform, but a zero-friction first-pass filter that catches the obvious issues before they accumulate into an audit finding.
Reviewer scorecard
“The MCP integration and frecency scoring for agents is genuinely useful — I've measurably reduced token burn in Claude Code sessions by pointing it at fff.nvim instead of raw glob calls. The Rust prebuilts mean zero configuration pain. Strong ship.”
“Sub-second scans in a single binary are exactly what's needed for AI-assisted coding workflows. I don't want to wait 20 seconds for SonarQube on every commit — I want instant feedback. FoxGuard as a pre-commit hook gives me a practical security floor without slowing down my agent loop.”
“Telescope and fzf-lua have years of plugin ecosystem maturity. The agent-aware MCP angle is clever marketing but how many Neovim users are also running Claude Code via MCP? The overlap feels narrow. Wait until the agent integrations mature.”
“Fast and incomplete beats slow and comprehensive only if you're disciplined about what fast tools catch. FoxGuard's 100 rules cover the obvious stuff, but sophisticated injection patterns, logic bugs, and auth flaws require semantic analysis. Don't let this become a false security ceiling that lets the real issues slide.”
“Agent-aware developer tools are a new category. Once your IDE and file search are MCP-native, the agent can navigate your codebase as efficiently as an experienced human dev — without wasting 40% of its context window just finding the right files.”
“Security tooling that keeps pace with AI code generation velocity is a genuine gap. The Rust ecosystem building fast-path analyzers is the right architectural response to the agent coding era. FoxGuard is early but directionally correct — expect this category to consolidate quickly as the attack surface from AI-generated code becomes undeniable.”
“This is deeply Neovim-specific and developer-focused. If you're not living in a terminal editor with AI agents piped into your workflow, nothing here is for you. Pass.”
“As someone who builds with AI-generated code but doesn't have a security background, having a tool that catches hardcoded secrets and basic injection patterns before I deploy is genuinely reassuring. A single binary with no setup cost means I'll actually use it, which is the only security tool that matters.”
