Looking at gateways? Look at the whole stack.

LLM gateways route. MCP tools connect. Barndoor does both — and governs across every LLM, agent, MCP server, tool call, and data flow from one control plane.

The Difference

One control plane, not a stack of point solutions.

Most options solve one piece — an LLM gateway here, an MCP gateway there. Barndoor brings the LLM gateway, MCP governance, and data protection together under one policy engine, one identity layer, and one audit trail.

One Unified Platform

LLM gateway and MCP governance, on one control plane.

Stop stitching a gateway to a registry to a policy engine to an audit tool. Barndoor delivers LLM Gateway, MCP Governance, and Data Protection as one platform — so the same controls and audit trail apply across every model, agent, and tool call.

• Three solutions, one platform — LLM Gateway, MCP Governance, and Data Protection, managed together instead of bolted on.
• One identity layer — Set policy by identity, system, MCP, tool, model, or data — for both people and agents.
• One audit trail — Know exactly who did what, with which tool, and when, across every user, agent, and MCP server.

MCP Governance

Govern every agent, MCP server, and action.

Manage every agent and MCP connection your teams use — official, custom, local, or Barndoor-hosted — with the access controls and audit trail to back it up.

• Turn AI & MCP sprawl into approved access — See and control LLM usage, MCP servers, and tool calls across your environment.
• Least-privilege permissions for AI — Scope down permissions for AI on behalf of the people using it before it reaches your systems or alters your data.
• Intelligent MCP tool selection — Narrow the context window for every agent to the tools that fit the task and stay within policy.

LLM Gateway

Route, control, and observe every model.

Route every call to the right model, manage access, and control cost with full visibility — across OpenAI, Anthropic, Google, and 100 more, behind one endpoint.

• Universal endpoint — Connect every model through a single API endpoint, set routing and failover when providers go down.
• Cost control by user, team, or model — Cap token spend and request volume so LLM spend stays predictable.
• Data protection inline — Detect prompt injection and tokenize, mask, redact, or omit PII and secrets before they reach any model.

Why teams switch to Barndoor.

01

No AI vendor lock-in

Bring any model provider under the same policies, controls, and audit trail. Swap them anytime without rebuilding governance.

Connect to any MCP

Official, custom, local, or Barndoor-hosted — the same access controls and audit trail across every MCP server.

03

One policy engine

PII, secrets, and prompt threats handled under one reusable policy across both the LLM Gateway and MCP Governance.

04

Predictable AI spend

See and control AI spend across every model, agent, team, and user. Caps that hold end to end, with full visibility.

05

One audit trail

Every approved, denied, or restricted call logged with full context — attributable to a user, role, or agent.

06

Universal kill switch

One control across the business. Freeze a single agent, a whole team, a model provider, or every AI call at once.
