MCP client - Inviolet

Govern any Model Context Protocol client (Claude Desktop, Cursor, custom MCP hosts). Every tool invocation is intercepted before the MCP server executes.

Install

npm install @inviolet/agent-sdk-mcp-client @inviolet/agent-sdk-core

Use

import { Client } from '@modelcontextprotocol/sdk/client'
import { Inviolet } from '@inviolet/agent-sdk-core'
import { wrapMcpClient } from '@inviolet/agent-sdk-mcp-client'

const inviolet = new Inviolet({ /* ... */ })

const client = wrapMcpClient(new Client({ /* ... */ }), {
  inviolet,
  intentId: 'intents:engineering_lookup',
  actor: 'alice@example.com',
  audience: 'github-prod',
})

const result = await client.callTool('search_repos', { q: 'org:inviolet' })

Pairing with the MCP responder

For desktop hosts (Claude Desktop, Cursor), pair the client wrap with the apps/mcp-responder server-side responder running locally. The responder enforces the same gateway decisions inside the MCP host even when the client wrap isn’t present.
