Anthropic Integration

Add SOVR to Claude tool use.

Setup

import Anthropic from '@anthropic-ai/sdk';
import { SovrClient } from '@sovr/sdk';

const anthropic = new Anthropic();
const sovr = new SovrClient({
  tenantId: process.env.SOVR_TENANT_ID!,
  apiKey: process.env.SOVR_API_KEY!,
});

Protected Execution

async function executeWithSovr(toolName: string, input: any) {
  const check = await sovr.gate.check({
    action: toolName,
    context: input,
  });

  if (check.decision === 'allow') {
    return await executeTool(toolName, input);
  }
  return { blocked: true, reason: check.reason };
}

Full Example

const tools = [{
  name: 'send_email',
  input_schema: {
    type: 'object',
    properties: {
      to: { type: 'string' },
      subject: { type: 'string' },
    },
  },
}];

async function runAgent(prompt: string) {
  let messages = [{ role: 'user', content: prompt }];

  while (true) {
    const response = await anthropic.messages.create({
      model: 'claude-sonnet-4-20250514',
      max_tokens: 4096,
      tools,
      messages,
    });

    if (response.stop_reason === 'end_turn') {
      return response.content;
    }

    if (response.stop_reason === 'tool_use') {
      const results = [];
      for (const block of response.content) {
        if (block.type === 'tool_use') {
          const result = await executeWithSovr(block.name, block.input);
          results.push({
            type: 'tool_result',
            tool_use_id: block.id,
            content: JSON.stringify(result),
          });
        }
      }
      messages.push({ role: 'assistant', content: response.content });
      messages.push({ role: 'user', content: results });
    }
  }
}
