Legal Doc Analyzer MCP server

MCP Legal Document Analyzer

npm mcp-legal-doc-analyzer package

Domain-specific MCP tooling for legal document workflows. Extract key clauses from contracts, flag risky provisions against configurable rule templates, compare document versions at the clause level, and check compliance against standard checklists — all locally, without documents leaving your machine.

Key features

• Clause extraction: Identifies and labels clause boundaries (termination, liability, IP, governing law, and more) from PDF, DOCX, and plain-text files.
• Risk flagging: Checks extracted clauses against YAML rule templates and returns severity-ranked findings.
• Compliance checking: Validates documents against structured checklists (NDA, employment agreement, SaaS terms) with pass/fail per requirement.
• Version diffing: Compares two versions of a document at the clause level — not raw text lines.
• Configurable templates: Rule sets are YAML files that legal professionals can review and edit without writing code.
• Local-only processing: All parsing and analysis runs on-device; documents are never transmitted externally.

Disclaimers

mcp-legal-doc-analyzer is an analysis aid, not legal advice. Outputs should be reviewed by a qualified legal professional before making decisions. Clause extraction uses pattern matching and heuristics; results may be incomplete or incorrect for non-standard document formats. Low-confidence extractions are flagged explicitly.

Document contents are processed locally and stored in a local SQLite database. Do not share database exports containing confidential documents.

Requirements

• Node.js v20.19 or newer.
• npm.

Getting started

Add the following config to your MCP client:

{
  "mcpServers": {

      "args": ["-y", "mcp-legal-doc-analyzer@latest"]
    }
  }
}

To load custom compliance templates from a directory:

{
  "mcpServers": {
    "legal-analyzer": {
      "command": "npx",
      "args": ["-y", "mcp-legal-doc-analyzer@latest", "--templates=~/legal/my-templates"]
    }
  }
}
