What is MCP_DinCoder CLAUDE.md?

A set of instructions for an AI agent working on MCP_DinCoder, a server that helps organize software development around written specifications. It explains the project, its requirements, and how AI-discovered workflow prompts should work.

It is for building or maintaining the MCP_DinCoder server, including its HTTP connection, TypeScript setup, and specification-driven workflows such as defining a project, planning it, and creating tasks.

It gives the agent the repository rules and the intended behavior of its prompts, reducing guesswork during development. MCP is a standard way for AI agents to connect to tools and services.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01557	$0.01557
Opus 5.5	$0.00623	$0.00623
Sonnet 5.5	$0.00311	$0.00311
Haiku 4.5	$0.00156	$0.00156

Security

Grade A, and why

MCP_DinCoder CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to AI agents when working with code in this repository.

Project Overview

Spec-Driven MCP Orchestrator - Model Context Protocol server with Streamable HTTP transport, exposing Spec Kit tools (specify, plan, tasks) for AI-assisted spec-driven development workflows.

Critical Requirements

Protocol: MCP Streamable HTTP (Protocol Revision 2025-03-26)
TypeScript SDK: @modelcontextprotocol/sdk v1.17.5+
Node.js: >=20
Transport: HTTP only (STDIO deprecated Sept 7, 2025)
TypeScript Config: MUST use module/moduleResolution: "NodeNext"

⚠️ MCP Prompts - CRITICAL UNDERSTANDING

MCP prompts are workflow orchestrators for AI agents, NOT user-typed commands.

How They Work

AI Discovery: Agents discover prompts via prompts/list JSON-RPC call
AI Invocation: Agents call prompts/get programmatically when relevant
User Experience: Users describe goals in natural language; AI uses appropriate prompt automatically

Example

User: "Let's start a new project called task-manager"

Behind the scenes:

AI recognizes this matches start_project prompt
AI invokes prompt programmatically
AI receives workflow instructions
AI guides user through setup

User sees: Natural conversation (NOT a slash command)

Platform Behavior

Claude Code: @ = files, / = native commands, MCP prompts = invisible
VS Code/Copilot/Cursor: MCP prompts integrated into agent workflows

Registered Prompts (v0.4.0+)

Prompt	Purpose	Arguments
`start_project`	Initialize new project	projectName, agent (optional)
`create_spec`	Create specification	description
`generate_plan`	Generate implementation plan	specPath (optional)
`create_tasks`	Break down into tasks	planPath (optional)
`review_progress`	Generate progress report	None
`validate_spec`	Check specification quality	specPath (optional)
`next_tasks`	Show actionable tasks	limit (optional)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
