An API Gateway is Not an AI Gateway

Kong is fundamentally an API gateway, engineered for cheap, instant, stateless API calls, not expensive, chained AI requests. TrueFoundry was built AI-native, with AI Gateway, MCP Gateway, and Agent Gateway deployed inside your VPC.

Built AI-Native. Not Bolted On.

Kong added AI capability as ~20-25 plugins on top of an API gateway. The result is 4-5x more setup each time you add a model on Kong versus TrueFoundry.

Complete Cost Observability

Kong has no per-token cost tracking for self-hosted customers, and no way to enforce cost-based policies. TrueFoundry has both, natively.

Human-in-the-Loop for Agents

Kong's MCP Gateway has no way to pause a tool call for human approval. With TrueFoundry, you can govern every agentic action even as you scale.

Production challenges

Why teams look for a Kong alternative

Kong might work as an API Gateway, but as teams move AI workflows into large-scale production, they begin to see the limitations of extending Kong as an AI Gateway.

Kong sees one call at a time

One agent request turns into dozens of model and tool calls. Kong checks each one on its own and forgets it, so nothing tracks what the full request cost, who it ran for, or whether it should have been allowed.

You can't require human sign-off on an agent action

Kong has no way to hold a tool call while a person reviews it. So an agent that can send money, delete records or push code does it the moment it decides to — which is why most teams keep their agents read-only.

You get token counts, not spend

Kong counts tokens, not dollars. To see cost, someone on your team enters the price of every model by hand and updates it each time a provider reprices. Self-hosted models get no cost tracking at all, and there is no way to set a budget that actually blocks a request.

Guardrails don't check what tools do

Kong's guardrails read prompts and model responses only. The tool call itself, and the data it sends back, are never inspected, so a prompt-injection test passes while the risky path goes unchecked.

Debugging means piecing logs together

Kong doesn't give a request one shared ID across its plugins, so the model call, the tool call and the guardrail all land in different places. Every investigation starts with rebuilding what happened by hand.

Kong routes to models, it doesn't run them

Deploying, fine-tuning and serving your own models are outside Kong's scope. The day you move a workload to a private model, you are buying and integrating a second platform.

The fix

How TrueFoundry acts as a painkiller

Where Kong breaks

How TrueFoundry solves it

Business impact

Limited MCP and agent governance

Human approval gates on destructive tool calls, pre/post-tool guardrail hooks, Virtual MCP Servers

Every risky action has a named approver and a recorded decision. Agents move from pilot to production.

No dollar-based cost controls

Native per-token cost tracking, budgets enforced on the hot path, attribution by team, user, model and application

Budgets stop overspend at the limit, not after the invoice. Nobody reconciles model prices by hand.

Plugin complexity that grows with your stack

One virtual model object per model — adding or swapping a model is a single change

Engineering time shifts from gateway plumbing to AI products. The configuration surface stays flat.

Incomplete data sovereignty

Auth, rate limits, guardrails and PII/PHI detection all run in-process inside your cluster

Security signs off without exceptions. Regulated and air-gapped workloads use the same architecture.

No native support for self-hosted models

External API routing and self-hosted deployment from one interface

No second platform, no second integration, no unbudgeted migration.

Slow time-to-production

Platform teams set policy once; application teams self-serve within those bounds

Teams ship in hours, not tickets. The platform team stops being the bottleneck.

Route on dollars, not just requests

Latency-based routing, per-team budgets enforced before spend, and guardrails that read prompts and tool calls. No AI plugin required.

Evaluation checklist

Six things to pressure-test before you standardize

Before using Kong as your AI Gateway, ask your provider these six critical questions.

Ask to see a tool call held for a person

Authorization and approval are not the same thing. An agent with valid credentials and correct permissions can still delete the wrong database, and every check will have passed.

Test guardrails on a tool call, not a prompt

Most evaluations send a prompt-injection string and confirm it is blocked. Kong's guardrails attach per Route or Service, so they never see the tool-call path.

Count configuration cost every time, not once

The first model looks reasonable anywhere. Multiply by every model, provider and environment over two years.

Confirm you can cap, alert on and attribute spend in dollars

Token limits are not budgets. Models differ by orders of magnitude per token, so a request well inside quota can still be expensive.

Check what "on-prem" actually means

Ask where the control plane runs in the hybrid deployment, and which compliance features are license-gated.

Ask what state survives a request

Approval gates, brokered per-user credentials and long-running agent loops all need state that outlives the call. Without it, your team owns the orchestration layer indefinitely.

How to decide

When to settle and when to scale

Choose TrueFoundry when

You are adding models and teams faster than you can configure a Service, Route, and plugin for each one
You are running agents that execute tool calls which write, transact, or deploy
You need spend attributed by team and capped in dollars before a request is made
You need security and compliance to see data residency, guardrails, and approval records
You expect to run self-hosted or fine-tuned models alongside provider APIs

Kong might be adequate when

You are running one or two providers and a small set of models from a single team
You are still in prototypes and internal tools, where an incorrect response carries limited consequence

Perguntas Frequentes/Objeções Comuns

Precisamos substituir o Kong?

Não. O Kong é um excelente gateway de API e merece o seu lugar na sua stack. A resposta prática é a divisão de tarefas: o Kong permanece na borda para REST, gRPC e Kafka; um gateway de IA especializado assume o tráfego de LLM, MCP e agentes. O TrueFoundry é implementado em paralelo.

O Kong tem um plugin OAuth para MCP. Isso não cobre a autenticação?

Ele cobre quem está chamando seu gateway, não em nome de quem seus agentes agem a jusante. O Kong valida tokens de entrada e oferece suporte à troca de tokens onde seu provedor de identidade a oferece, mas não há fluxo de consentimento de código de autorização para provedores terceirizados. Para que um agente aja como uma pessoa específica no Slack ou GitHub, seus engenheiros precisam criar e operar o consentimento, o armazenamento de tokens e a atualização.

Podemos esperar? O Kong é entregue rapidamente.

Algumas lacunas fazem parte do roteiro. Duas são escolhas de design: a aplicação de aprovação é delegada ao cliente do agente, e a autenticação de ferramentas por usuário pressupõe que seu provedor de identidade cuida disso. Fechar qualquer uma delas exige o que um proxy baseado em fases foi criado para evitar — um estado que sobrevive à solicitação. Esse é um novo subsistema com estado, com seu próprio armazenamento, failover e locação, não um plugin.

Nós só fazemos roteamento de modelos hoje. Precisamos disso?

A TrueFoundry funciona bem como uma camada de roteamento leve com monitoramento, guardrails e controle de custos. Mas o roteamento é a parte fácil de mover depois. Portões de aprovação, credenciais por usuário e custo por nível de cadeia são o que forçam uma mudança de plataforma.

O que muda no primeiro dia?

Nada na sua borda. Você direciona o tráfego de IA para o gateway de IA e mantém o Kong onde ele está.
