How do I use PromptSmith?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@PromptSmith Recommend a reasoning strategy for architecting a global supply chain" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

PromptSmith

Reasoning as a Service - A Capability-Level 0 MCP Server that provides intelligent reasoning framework selection and meta-prompt generation for AI agents.

Purpose

PromptSmith analyzes tasks, determines their complexity and category, and generates optimized "meta-prompts" using the most appropriate reasoning framework.

Features

🧠 40 Reasoning Frameworks: Chain of Thought, Tree of Thoughts, ReAct, Reflexion, Graph of Thoughts, Program of Thoughts, and more
📊 Intelligent Task Analysis: Automatic category detection (code, math, logic, creative, research, data, planning) and complexity scoring (0–10)
🎯 Framework Selection: Heuristic-based selection of the optimal reasoning strategy
💾 Persistence: SQLite storage for reasoning traces and analytics
📈 Usage Statistics: Track framework usage and effectiveness

Installation

git clone https://github.com/your-org/promptsmith cd promptsmith uv sync

MCP Tools

Tool	Description
`recommend_strategy`	Analyze a task and recommend the optimal reasoning framework
`generate_meta_prompt`	Generate an optimized meta-prompt for a task
`log_execution_feedback`	Record feedback about prompt effectiveness
`list_available_frameworks`	List all available reasoning frameworks
`get_usage_stats`	Get usage statistics and analytics

Usage

As MCP Server

Add to your MCP client configuration (e.g. .mcp.json in your project root):

{ "mcpServers": { "promptsmith": { "command": "uv", "args": ["run", "--directory", "/path/to/promptsmith", "python", "-m", "promptsmith.main"], "env": { "PYTHONPATH": "/path/to/promptsmith/src", "UV_LINK_MODE": "copy", "FASTMCP_SHOW_STARTUP_BANNER": "false" } } } }

Programmatic Usage

from promptsmith.domain import FrameworkSelector, PromptBuilder # Analyze a task selector = FrameworkSelector() analysis = selector.analyze("Write a recursive function to calculate fibonacci numbers") print(f"Category: {analysis.category}") # code print(f"Complexity: {analysis.complexity_score}") # ~3.3 print(f"Framework: {analysis.recommended_framework}") # program_of_thoughts # Generate a meta-prompt builder = PromptBuilder() result = builder.build(analysis.task, analysis=analysis) print(result.meta_prompt)

Integration with Other Agents

PromptSmith is designed to be called by other MCP-enabled agents.

result = mcp_call("promptsmith", "generate_meta_prompt", { "task": user_query, "context": relevant_context, }) enhanced_response = llm.generate(result["meta_prompt"])
