Road Poneglyph

A local MCP server with one tool that runs a structured pre-mortem on a plan and reports unstated assumptions, omitted risks and execution gaps.

What you can do

• Analyze a plan for blind spots: the tool takes the plan text and an optional project type and returns a focused pre-mortem analysis.
• Surface unstated assumptions the plan depends on without proof.
• Flag omitted technical and architectural risks.
• Point out operational and execution gaps on the way to shipping.
• The server does not call a language model itself; it returns an engineered analysis prompt that the assistant you are already talking to executes.

When to use it

Useful before committing to a plan, design or rollout, when you want a critique of what is missing rather than a reaction to what is written. Good for software projects and other plan types, since the project type can be specified.

Requirements

Runs as a local process over stdio; requires Python 3.10 or newer and the road-poneglyph-mcp package (for example via uvx or pip), which installs the road-poneglyph command. Register it in an MCP client such as Claude Desktop, Claude Code or Cursor. No API key, credentials or network access needed.
