Hex MCP Servers

Token-efficient MCP servers for AI coding agents. Hash-verified editing, deterministic project scope, remote SSH ops, code knowledge graphs.

hex-line-mcp

9 tools: hash-verified file editing, AST outline, graph-aware review hints, and auto-synced hooks + output style that steer agents to explicit project scope. 89% avg token savings across 4 session-derived workflow benchmarks.

npm i -g @levnikolaevich/hex-line-mcp View details →

hex-ssh-mcp

8 tools: remote file editing plus SFTP upload/download over SSH with FNV-1a hash verification, output normalization, and deduplication. Runs on Windows/macOS/Linux hosts.

Choose your plugin

Add the marketplace once, then install only the plugins you need. Each works independently.

⚙

Agile Workflow

End-to-end artifact-driven delivery pipeline: scope decomposition, Story/Task management, stateful workers, multi-model validation, quality gates, and autonomous orchestration.

🔍

Codebase Audit Suite

Parallel auditors for security, code quality, architecture patterns, test suites, and persistence performance. Run on any existing codebase.

/plugin install codebase-audit-suite@levnikolaevich-skills-marketplace View skills →

📄

Documentation Pipeline

Auto-detect project type (backend, frontend, devops) and generate complete documentation suite: architecture, API spec, runbook, and more.

/plugin install documentation-pipeline@levnikolaevich-skills-marketplace View skills →

🚀

Project Bootstrap

CREATE new or TRANSFORM existing projects to production-ready Clean Architecture with Docker, CI/CD, linters, and security scanning.

/plugin install project-bootstrap@levnikolaevich-skills-marketplace View skills →

⚡

Optimization Suite

Multi-cycle performance profiling, dependency upgrades (npm, NuGet, pip), code modernization, and bundle size optimization.

🌐

Community Engagement

Automated GitHub community management: triage issues and PRs, compose announcements, launch RFC debates, respond to discussions.

/plugin install community-engagement@levnikolaevich-skills-marketplace View skills →

🛠

Setup Environment

Install CLI agents, configure MCP servers, align marketplace plugins across agents, and audit instruction files. One-command multi-agent setup.

What you can do

Each scenario works standalone. Combine plugins for the full lifecycle.

▶
Audit an existing codebase
Security, quality, architecture, tests, performance — parallel auditors scan everything at once.
▶
Bootstrap or restructure a project
Go from zero to production-ready Clean Architecture, or transform legacy projects without starting over.
▶
Generate complete documentation
Architecture docs, API specs, runbooks — auto-detected by project type.
▶
Optimize performance and dependencies
Profile bottlenecks, research solutions, test hypotheses with keep/discard loop, upgrade outdated packages.
▶
Run the full Agile pipeline
Scope → Epics → Stories → Tasks → Implementation → Review → Quality Gate → Done.

Quick start

Add the marketplace, install what you need, then run. No configuration required.

Key features

Built for real-world software delivery at scale.

External AI Review

The current host cross-checks code with the non-host advisor from the Claude/Codex registry, with graceful fallback when no advisor is available.

Orchestrator-Worker Architecture

4-level hierarchy (L0–L3) with single responsibility per skill. Each agent loads only what it needs.

No Vendor Lock-in

Works without Linear, without MCP servers, without API keys. Falls back to local markdown files automatically.

Quality Gates

4-level gate (PASS / CONCERNS / WAIVED / FAIL) with quantitative scoring. Nothing ships without passing.

Pipeline Orchestrator

Autonomous multi-agent system manages the full lifecycle: plan, validate, implement, review, and merge.

Cross-Agent Compatibility

Use skills from Claude Code and OpenAI Codex. Keep configs aligned with one command.
