xerj

xerj-org/xerj · ★ 10.5K

XERJ is a local-first search engine that automatically indexes any folder - code, docs, logs, PDFs - so an AI coding agent can pull the exact passage it needs instead of grepping or reading whole files into context, and it speaks the Elasticsearch API so existing clients work against it unchanged.

context-mode

mksglu/context-mode · ★ 31.2K

Context Mode is an MCP server plus hooks that keeps bulky tool output out of your AI coding agent's context window (98% reduction), persists session memory, and enforces tool routing across 17 platforms.

+39

Seep-Reverse-Lab

angusdevgo/Seep-Reverse-Lab · ★ 1.7K

Seep Reverse Lab is an agent-native reverse engineering and security-audit workbench that lets an AI coding agent autonomously run Radare2, JADX, Apktool and Frida to triage binaries, decompile APKs, and determine whether an app's feature gates are enforced locally or verified by a server (a CWE-602 authorization audit).

0x4m4/hexstrike-ai · ★ 12.9K

HexStrike AI MCP Agents is an MCP server that lets AI agents like Claude, GPT, or Copilot autonomously run 150+ real cybersecurity tools for automated pentesting, bug bounty hunting, CTF challenges, and vulnerability discovery.

    mintocode

    477Spearmintai/mintocode · Python

    mic compiles your codebase once into agent-facing 'cards' (what each function does, its gotchas, its callers, its tests), so that Claude Code, Codex or any MCP agent only reads the few paragraphs relevant to a question instead of exploring the whole repo.

    Benzi

    169oooscoos/Benzi · HTML

    Benzi is a compiler-backed coding agent: it parses your whole codebase with tree-sitter into a queryable index of symbols, calls, and data/control flow, then uses that map to explain, edit, and verify code changes, including a runtime tracer that settles what static analysis alone can't.
