Claude Prompts MCP Server

Hot-reloadable prompts, structured reasoning, and chain workflows for your AI assistant.

Quick Start • What You Get • Syntax • Docs

Why

Stop copy-pasting prompts. This server turns your prompt library into a programmable engine:

• Version Control — Prompts are YAML + templates in git. Track changes, review diffs.
• Hot Reload — Edit a template, run it immediately. No restarts.
• Structured Execution — Parses operators, injects methodology, enforces quality gates.

The feedback loop: You send a command with operators → Server parses and injects methodology/gates → Claude executes and self-evaluates → Server routes: next step (PASS), retry (FAIL), or return result (done).

Quick Start

Claude Code (Recommended)

Step 1: Add the plugin marketplace (first time only)

/plugin marketplace add minipuft/minipuft-plugins

Step 2: Install the plugin

/plugin install claude-prompts@minipuft

Step 3: Try it

>>tech_evaluation_chain library:'zod' context:'API validation'

User Data: Custom prompts stored in ~/.local/share/claude-prompts/ persist across updates.

Gemini CLI

# Install directly from GitHub
gemini extensions install https://github.com/minipuft/claude-prompts-mcp

# Development Setup (Hot Reload)
# Use a symbolic link to point the extension directory directly to your source code.
# This ensures changes to hooks and prompts are reflected immediately.
rm -rf ~/.gemini/extensions/gemini-prompts
ln -s "$(pwd)" ~/.gemini/extensions/gemini-prompts

The extension provides:

• MCP server with the same tools (prompt_engine, resource_manager, system_control)
• GEMINI.md context file with usage documentation

Optional hooks for >>prompt syntax detection can be enabled manually - see GEMINI.md for setup instructions.

Works with the same prompts, gates, and methodologies as Claude Code.

Claude Desktop

Desktop Extension (one-click):

1. Download claude-prompts.mcpb → github.com/minipuft/claude-prompts-mcp/releases
2. Drag into Claude Desktop Settings
3. Done. Optionally set a custom prompts folder when prompted.

NPX (auto-updates):

// ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)
// %APPDATA%\Claude\claude_desktop_config.json (Windows)
{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest"]
    }
  }
}

Restart Claude Desktop. Test it:

>>research_chain topic:'remote team policies' purpose:'handbook update'

→ Returns a 4-step research workflow with methodology injection and quality gates.

Other MCP Clients

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest"]
    }
  }
}

Cursor 1-click install

git clone https://github.com/minipuft/claude-prompts-mcp.git
cd claude-prompts-mcp/server && npm install && npm run build

Custom Resources

Use your own prompts without cloning:

{
  "mcpServers": {
    "claude-prompts": {
      "command": "npx",
      "args": ["-y", "claude-prompts@latest"],
      "env": {
        "MCP_RESOURCES_PATH": "/path/to/your/resources"
      }
    }
  }
}

Your resources directory can contain: prompts/, gates/, methodologies/, styles/.

Priority: CLI flags > individual env vars > MCP_RESOURCES_PATH > package defaults.

See CLI Configuration for all options.

What You Get

🔥 Hot Reload

Edit prompts, test immediately. Better yet—ask Claude to fix them:

User: "The code_review prompt is too verbose"
Claude: resource_manager(action:"update", id:"code_review", ...)
User: "Test it"
Claude: prompt_engine(command:">>code_review")  # Uses updated version instantly

🔗 Chains

Break complex tasks into steps with -->:

analyze code --> identify issues --> propose fixes --> generate tests

Each step's output flows to the next. Add quality gates between steps.

🧠 Frameworks

Inject structured thinking patterns:

@CAGEERF Review this architecture    # Context → Analysis → Goals → Execution → Evaluation → Refinement
@ReACT Debug this error              # Reason → Act → Observe loops

🛡️ Gates

Quality criteria Claude self-checks:

Summarize this :: 'under 200 words' :: 'include key statistics'

Failed gates can retry automatically or pause for your decision.

✨ Judge Selection

Let Claude pick the right tools:

%judge Help me refactor this codebase

Claude analyzes available frameworks, gates, and styles, then applies the best combination.

📜 Version History

Every update is versioned. Compare, rollback, undo:

resource_manager(action:"history", id:"code_review")
resource_manager(action:"rollback", id:"code_review", version:2, confirm:true)

Syntax Reference

Modifiers:

• %clean — No framework/gate injection
• %lean — Gates only, skip framework
• %guided — Force framework injection
• %judge — Claude selects best resources

Using Gates

# Inline (quick)
Research AI :: 'use recent sources' --> Summarize :: 'be concise'

# With framework
@CAGEERF Explain React hooks :: 'include examples'

# Programmatic
prompt_engine({
  command: ">>code_review",
  gates: [{ name: "Security", criteria: ["No hardcoded secrets"] }]
})

See Gates Guide for full schema.

Configuration

Customize via server/config.json:

The Three Tools

prompt_engine(command:"@CAGEERF >>analysis topic:'AI safety'")
