contract-analyzer

Contract analyzer

Extracts and risk-rates contract clauses from a PDF or scanned document using Mistral's native document AI. No third-party OCR dependency.

Profile requirements:

• mistral_ocr + mistral_chat — available in core profile (default)
• files_upload (to upload a local PDF) — requires MISTRAL_MCP_PROFILE=full
• If the user provides a public URL, this skill runs entirely on the core profile

EU data residency: both mistral_ocr and mistral_chat stay within Mistral's EU infrastructure when the API key is an EU-region key.

Steps

Step 1 — Get the document

Ask the user for one of:

• A public URL (direct link to the PDF) — works with core profile
• A local file path → upload with files_upload (requires MISTRAL_MCP_PROFILE=full), note the returned file_id

Step 2 — OCR the contract

Call mistral_ocr with document_annotation_format: "markdown" for structured extraction:

{
  "document": {
    "type": "document_url",
    "documentUrl": "<URL from step 1>"
  },
  "document_annotation_format": "markdown"
}

If using a file upload: "type": "document_id", "documentId": "<file_id>" instead.

Concatenate structuredContent.pages[*].markdown across all pages.

Step 3 — Extract structured clauses

Pass the concatenated OCR text to mistral_chat with mistral-large-latest and a json_schema response format:

{
  "model": "mistral-large-latest",
  "temperature": 0,
  "response_format": {
    "type": "json_schema",
    "json_schema": {
      "name": "contract_analysis",
      "strict": true,
      "schema": {

                "summary": { "type": "string" },
                "risk_level": {
                  "type": "string",
                  "enum": ["low", "medium", "high", "critical"]
                },
                "risk_reason": { "type": "string" }
              },
              "required": ["title", "summary", "risk_level", "risk_reason"]
            }
          },
          "overall_risk": {
            "type": "string",
            "enum": ["low", "medium", "high", "critical"]
          },
          "missing_protections": {

      }
    }
  },
  "messages": [
    {
      "role": "user",
      "content": "<OCR text>\n\nExtract all clauses from the contract above. For each clause, provide a title, one-sentence summary, and risk level (low/medium/high/critical) with the reason.
