Inviolet integrates with Claude in three places: the Anthropic SDK (server-side agents), Claude Desktop (employee assistants), and Claude for Work via the Model Context Protocol (MCP) endpoint Inviolet hosts. Same intent-token issuance across all three.

​
Why it matters

Claude tool calls are the dominant traffic shape for most early adopters. Wrapping the Anthropic SDK takes one line and gives you intent extraction + audit log + (optionally) policy enforcement on every messages.create call.

​
1. Wrap the Anthropic SDK (server-side)

import { InViolet } from "@inviolet/sdk"
import Anthropic from "@anthropic-ai/sdk"

const inviolet = new InViolet({ apiKey: process.env.INVIOLET_API_KEY! })
const anthropic = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY! })

// Before every tool call, ask Inviolet whether to allow it.
const decision = await inviolet.intent.evaluate({
  userId: "user_2pX9...",
  toolCall: { name: "lookup_customer", arguments: { id: "12345" } },
  dataSourceId: "salesforce_prod",
})

if (decision.outcome !== "allowed") {
  throw new Error(`call_blocked: ${decision.outcome}`)
}

// Proceed with the original Anthropic call.
const message = await anthropic.messages.create({
  model: "claude-sonnet-4-5",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Look up customer 12345." }],
})

​
2. Claude Desktop via MCP

Claude Desktop speaks MCP. Inviolet hosts an MCP server at https://gateway.inviolet.ai/mcp exposing read-only tools (purposes.list, approvals.list, intent.evaluate). Add this to Claude Desktop’s claude_desktop_config.json: 
{
  "mcpServers": {
    "inviolet": {
      "url": "https://gateway.inviolet.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${INVIOLET_API_KEY}"
      }
    }
  }
}

​
3. Verify

Open the decision feed at app.inviolet.ai/decision-feed. Make a tool call from the Anthropic SDK or ask Claude Desktop a question that uses the MCP tool. The event appears within seconds with the matched purpose, the intent class, and the issued (or withheld) intent token.
