Self-Hosted MCP Gateway & Agent Tool Control

Every MCP server behind one governed, sandboxed boundary.

Broker, sandbox, and govern every MCP tool call inline

Model Context Protocol lets agents reach external tools – and reach trouble if those tools are ungoverned. DeepintShield is a self-hosted MCP gateway that brokers every server behind one trust boundary, discovers and health-checks their tools, and authorizes each call through the same policy engine. For higher autonomy it runs a sandboxed code mode with no network, filesystem, or imports.

Key Features

Multi-transport Brokering

Connect MCP servers over streamable-HTTP, stdio, SSE, and in-process, with health monitoring and automatic reconnect.

Two-layer allow-lists

An execution allow-list plus a separate auto-execution allowlist decide which tools exist and which may run hands-free.

Starlark code-mode Sandbox

Agents orchestrate many tools in one block with no network/filesystem/imports, deterministic execution, and AST-validated nested calls (Enterprise VPC).

Parallel-tool safety

A safety registry serializes state-mutating concurrent calls so tools like create_order never race.

Gateway-brokered OAuth

Centralize and rotate MCP credentials, including RFC 7591 dynamic client registration, instead of scattering secrets across agents.

One-line framework gating

Govern tools in LangGraph, CrewAI, OpenAI Agents, LlamaIndex, AutoGen, and PydanticAI with a single wrap.
