What is the Boilerplate MCP server?

Boilerplate becomes available to MCP clients through the boilerplate mcp server. A playground for Model Context Protocol (MCP) server built with TypeScript and Streamable HTTP transport.

What Boilerplate does

A playground for Model Context Protocol (MCP) server built with TypeScript and Streamable HTTP transport with an OAuth Proxy for 3rd party authorization servers like Auth0.

Key capabilities

  • MCP 2025-06-18 Compliant — Full compliance with the latest MCP specification including SSE resumability, tool annotations, and structured content
  • MCP Server implementation — HTTP-Based Streamable transport using @modelcontextprotocol/sdk with HTTP transport, session management, and tool execution
  • SSE Resumability — Clients can reconnect with Last-Event-ID header to resume receiving events after connection breaks, powered by EventStore
  • OAuth authentication/3rd party authorization — Implements an OAuth server for MCP clients with RFC 8707 Resource Indicators and RFC 9728 authorization discovery, delegating to Auth0
  • Storage — Pluggable storage abstraction (Memory/Valkey) with EventStore for SSE event persistence and replay
  • Session Management — Support stateful sessions by using replay of initial request for distributed deployments
  • Security — Strict Origin validation to prevent DNS rebinding attacks, WWW-Authenticate headers for authorization discovery
  • aws-ecs: Investigate the ECS service, task and cloudwatch logs using AWS ECS, Cloudwatch Logs and Bedrock

Tools it exposes

Once connected, the assistant can call these 14 tools directly:

  • Storage — Pluggable storage abstraction (Memory/Valkey) with EventStore for SSE event persistence and replay
  • Security — Strict Origin validation to prevent DNS rebinding attacks, WWW-Authenticate headers for authorization discovery
  • Tools — - aws-ecs: Investigate the ECS service, task and cloudwatch logs using AWS ECS, Cloudwatch Logs and Bedrock
  • aws-s3 — Get the list of S3 buckets and objects
  • system-time — Get the current system time in various formats with timezone support
  • echo — Echo a message back with transformations, repetition
  • streaming — Simulate real-time streaming data with live updates
  • project — Find keywords in the current project directory
  • Resources — - echo://documentation: Documentation for the echo tool (static resource)
  • Prompts — echo
  • Name — MCP Server Playground
  • Identifier — urn:mcp-server-playground
  • Endpoint — Description
  • Installation — The Installation tool exposed by this server

Installing the boilerplate mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Where it fits

Cloud and DevOps servers put infrastructure on speaking terms with your assistant, so "why is this broken?" is answered from real state rather than a generic checklist. Boilerplate sits in that group, and the shape of its toolset — Storage, Security, Tools among others — tells you what it is really for. Worth comparing against the other cloud devops servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • With 14 tools exposed, expect a noticeable bump in prompt size — disable it in projects that never use Boilerplate.
  • Maintained by chrisleekr, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the boilerplate mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

How to install the Boilerplate MCP server

{
     "mcpServers": {
       "mcp-server-playground-cursor": {
         "type": "http",
         "url": "http://localhost:3000/mcp"
       }
     }
   }

Configuration as documented by the project. Restart the client after saving.

Frequently asked questions

It connects Boilerplate to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (Storage, Security, Tools, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Boilerplate directly.
