patentorney-mcp

An MCP server for managing patent application drafts. Built with FastMCP and designed for use with AI coding assistants (Windsurf, Claude Desktop, etc.).

Installation

pip install patentorney-mcp

Or with uvx (no install needed):

uvx patentorney-mcp

MCP Client Configuration

For Windsurf / Claude Desktop, add to your MCP config:

{
  "mcpServers": {
    "patentorney-mcp": {
      "command": "uvx",
      "args": ["patentorney-mcp"]
    }
  }
}

On first use, call set_root(path='/absolute/path/to/project') to point the server at the directory containing patent.yaml. All other tools will prompt for this if it hasn't been set.

Tools (8)

Tool	Purpose
set_root(path)	Point at a patent project directory. Must be called first.
guide(topic?)	Usage guides. No args → index.
claim(action, ...)	Claims: add|get|update|remove|move|rename|tree
figure(action, ...)	Figures: add|get|update|remove|move|rename|list
numeral(action, ...)	Numerals: add|get|update|remove|lookup|rename|renumber|list
prior_art(action, ...)	Prior art & IDS: add|get|update|remove|list|ids_add|ids_list|ids_check
glossary(action, ...)	Glossary: add|get|update|remove|list
export(target, ...)	Status, validation & export: status|check|claims|drawings_description|claims_latex|drawings_latex|latex

Any tool called before set_root() returns an error with a hint to call it. All errors include LLM-actionable hints.

Architecture

• patent.yaml — single source of truth for structured data (claims, numerals, figures, glossary, prior art)
• sections/*.tex — prose sections edited directly; claims.tex and drawings-description.tex are generated
• Stable slug IDs — all entities use kebab-case slugs; presentation numbers computed from list order
• Dual addressing — tools accept slug or current number (e.g., claim("get", id="3") or claim("get", id="mof-synthesis-method"))
• File locking — fcntl.flock for safe concurrent access from multiple server instances
• Structured claims — preamble + transitional + elements (each with numeral associations)
