mcp-prompts

mcp-prompts

A Model Context Protocol server that stores, searches and serves prompt templates and agent configurations to any MCP client (Claude Desktop, Claude Code, Cursor and others), plus a script that uses those templates to orchestrate Claude CLI agents over a whole project.

Listed on Glama, MCP Market and AIBASE. A Rust reimplementation focused on memory efficiency and concurrency lives in mcp-prompts-rs.

What It Does

• Stores prompts as JSON files in data/prompts/
• Exposes MCP tools for querying and managing prompts
• Provides agent templates for project orchestration
• Works with Claude Desktop, Cursor, and other MCP clients

Packages

• npm: @sparesparrow/mcp-prompts
• Docker Hub: sparesparrow/mcp-prompts

Published releases lag behind main. To run what this README describes, build from source as below.

Quick Start

1. Install

pnpm install
pnpm build

2. Start MCP Server

pnpm start

3. Configure your MCP client

For Claude Desktop, add to claude_desktop_config.json (other clients take the same command and env):

{
  "mcpServers": {
    "prompts": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-prompts/dist/mcp-server-standalone.js"],
      "env": {
        "PROMPTS_DIR": "/absolute/path/to/mcp-prompts/data/prompts"
      }
    }
  }
}

4. Use in Claude

Ask Claude:

• "List all prompts tagged with orchestration"
• "Get the claudepy-esp32-android-bridge-workflow prompt"
• "Apply the claudepy-esp32-android-bridge-workflow template with esp32_firmware_path set to ./firmware"
• "Create a new prompt for Python FastAPI best practices"

HTTP Mode

The same prompts are also available as a JSON API, for clients that don't speak MCP:

pnpm build
PORT=3003 PROMPTS_DIR=$PWD/data/prompts pnpm start:http
# or: npx mcp-prompts-http, or the default Docker image (port 3003)

curl -s -X POST localhost:3003/v1/prompts/claudepy-esp32-android-bridge-workflow/apply \
  -H 'Content-Type: application/json' -d '{"variables":{"esp32_firmware_path":"./firmware"}}'

Invalid input answers 400, unknown prompts 404. Set CORS_ORIGIN to allow browser clients. Changes made over HTTP live in memory, like those made over MCP; the files in data/prompts are not rewritten.

Orchestrating Projects

Use the orchestrate script to analyze entire projects:

./scripts/orchestrate-project.sh ~/projects/mia analyze
./scripts/orchestrate-project.sh ~/projects/esp32-bpm-detector review

This automatically:

1. Detects project type
2. Loads appropriate main agent
3. Spawns specialized subagents
4. Runs comprehensive analysis
5. Returns structured results

Architecture

Two layers. The full server (src/mcp/mcp-server.ts) is hexagonal: the domain in src/core (entities, events, services and the repository and event-bus ports) knows nothing about storage or transport, and storage adapters plug in behind the ports — file and in-memory in src/adapters; the earlier DynamoDB, S3 and SQS adapters, Lambda handlers and CDK stack are kept in archive/aws and cdk/. The standalone server that pnpm start and the npm binary run is the small one below: it reads the JSON files in PROMPTS_DIR directly and speaks MCP over stdio.

Orchestration:
  orchestrate-project.sh
    ↓ loads prompts
    ↓ builds agent config
    ↓ calls claude CLI
  Actual agent execution

Development

pnpm install       # Install dependencies
pnpm build         # Build TypeScript
pnpm dev           # Watch mode
pnpm test          # Run tests
pnpm orchestrate   # Test orchestration

Enterprise Deployment

For enterprise features (AWS, multi-tenant, payments), see archive/aws/README.md.

Most users don't need this - the local MCP server is sufficient.
