API gateway extended to agent traffic: Kong AI Gateway governs model, MCP and agent-to-agent calls from one control plane, with RAG injection, LLM-as-judge scoring, guardrails and regional hosting.

Kong built its business on API gateways and has extended that position into what it calls AI connectivity: one governance and runtime layer across APIs, events, model calls, MCP connections and agent-to-agent traffic. This record grades that agent layer, Kong AI Gateway and its MCP and A2A gateways, not the whole API platform.

Kong AI Gateway puts model providers behind a universal LLM API, with AI Proxy Advanced balancing across the models a customer configures, token-based rate limiting, semantic caching and prompt compression.

Its MCP Traffic Gateway turns any REST API into an MCP server, aggregates several servers behind one endpoint and authenticates each AI consumer with key auth or OpenID Connect, and its A2A Traffic Gateway routes agent-to-agent calls, rewriting agent cards so traffic passes through the gateway.

Enterprise plugins add RAG at the gateway, where the AI RAG Injector embeds each prompt, searches a vector database the customer loads and injects the results, and an LLM-as-judge plugin that scores responses from 1 to 100 on live traffic.

Governance runs through the same layer: prompt and semantic guards, PII sanitization and third-party guardrails from AWS, Azure, Google and Lakera, an AI audit log format, and OpenTelemetry metrics for model, MCP and A2A traffic viewable in Konnect.

Konnect's control plane can be hosted in Australia, the EU, the Middle East, the US, India or Singapore, with data planes self-hosted or on Dedicated Cloud Gateways, and Konnect supports SSO through OpenID Connect or SAML. Kong governs agent traffic; it does not run agents, keep their memory or ask a person to approve their actions. A 30-day trial is free, Plus is billed monthly with the AI Gateway at $100 a month per model proxied, and Enterprise is custom.

Integrations

An API gateway heritage means very broad backend integration, extended to AI through LLM provider routing with load balancing and failover, native Model Context Protocol support, and an MCP Registry inside the Konnect API Service Catalog for registering, discovering and governing the MCP servers and tools agents use. Kong can generate MCP servers from existing API specifications, and Insomnia supports MCP testing.

In practice

A platform team registers every internal MCP server in one catalog so agents discover governed tools instead of engineers spinning up unmanaged servers across the business.

A security team enforces PII redaction and prompt guards at the gateway rather than trusting each model provider, keeping regulated data inside its own boundary.

A finance team caps token consumption per team at the gateway and meters AI usage back to internal cost centers rather than discovering the bill at the end of the month.

Integrations & Tool Calling Full

Any REST API can become an MCP server through the AI MCP Server entity in Kong AI Gateway's MCP Traffic Gateway, which also aggregates several MCP servers behind one endpoint for clients such as Claude Desktop and Cursor. AI consumers authenticate through an AI Auth Strategy (key auth or OpenID Connect, with OAuth2 metadata from the MCP spec), and AI Policies handle access control and observability. Agents take authenticated action on the customer's systems through the gateway.

Workflow Orchestration Not documented

Agent to agent requests pass through Kong's A2A Traffic Gateway, which routes them via AI Gateway, extracts task metadata and rewrites agent cards so clients route through the gateway; the agents and their steps run on the customer's own servers. No workflow definition or agent execution of Kong's own is documented, nothing that sequences, branches, retries or routes work across deterministic workflow nodes and autonomous agent steps.

Knowledge Grounding & RAG Full

RAG runs at the gateway through the AI RAG Injector plugin: content is sent to a configured vector database through the Admin API or decK, and for each request the gateway embeds the prompt, queries the vector database for the most similar content and injects it before the model call, with vector database access limited to the gateway. New customer knowledge enters a persistent index without retraining, and that index scales past the context window and stays queryable. Some of this sits on higher tiers.

Human Oversight & Guardrails Partial

Safety and data loss policies apply to model traffic automatically: prompt guards, semantic prompt and response guards, PII sanitization, and third party guardrails from AWS, Azure, Google Model Armor and Lakera, plus token based rate limits and per consumer access control on models, MCP servers and agents. These are constraints the customer controls on what an agent may do. No step where a person reviews, approves or must validate before an agent action commits is documented.

Sourcedeveloper.konghq.com/ai-gateway/ai-data-govread 2026-09-22

Security, Identity & Governance Full

Access controls are deep and documented: Konnect SSO through OpenID Connect or SAML with IdP attribute mapping, custom teams and roles, Konnect and Dev Portal audit logs, and on the AI Gateway itself AI Auth Strategies (key auth or OpenID Connect) authenticating each AI consumer for models, MCP servers and agents, with FIPS 140-3 support in Kong Gateway. No security attestation is confirmed on Kong's own pages.

Observability & Auditability Full

AI traffic is recorded for the customer's review: logs and LLM metrics viewable in Konnect or exported to any OpenTelemetry tool, a standardized AI audit log format for AI policies (Data Governance page), OpenTelemetry metrics for generative AI, MCP and A2A traffic, and protocol aware metrics and tracing for agent to agent calls. That gives step by step inspection of what agents sent and received, an audit record separate from runtime metrics, and export to the customer's own tools.

Memory & State Persistence Not documented

Kong AI Gateway governs traffic in flight: its documented AI plugins and entities cover proxying, guardrails, rate limiting, caching, RAG injection, MCP and A2A routing and observability, and none persists an agent's state or a user's context across sessions, so there is no memory layer with a stated scope and lifetime.

Sourcekonghq.com/pricingread 2026-09-22

Deployment & Data Residency Full

Konnect lets an organization host its control plane in a region it chooses (Australia, EU, Middle East, US, India or Singapore, picked in a region picker), with gateway services, routes, consumers and other objects kept in that geo. Dedicated Cloud Gateways run in named AWS regions, and data planes can be self hosted in hybrid, DB-less or traditional on premises topologies.

Sourcedeveloper.konghq.com/konnect-platform/geosread 2026-09-22

Prebuilt Agents, Templates & Packs Not documented

Prebuilt assets for AI traffic come as plugins (guardrails, prompt templates and decorators, rate limiting, caching, RAG injection) that configure or constrain the customer's agents rather than do work themselves, and the MCP Registry catalogs the customer's own MCP servers. No ready made workflows, templates or role specific agents for a buyer to adopt are published.

Sourcekonghq.com/pricingread 2026-09-22

Triggers & Channel Coverage Not documented

Every model call, MCP tool call and A2A call that passes through Kong AI Gateway is started by the caller and then routed, secured and observed in flight. No schedule, event or webhook that starts an agent run is documented; the gateway acts only on requests a client has already sent.

Model Flexibility & Routing Full

The customer chooses: Kong AI Gateway offers a universal LLM API across providers, with AI Proxy Advanced balancing across models the customer configures and LLM access control and authentication per consumer. The pricing page lists the universal LLM API, token based rate limiting and semantic caching on Plus and bills per unique model proxied.

APIs, SDKs & MCP Extensibility Full

Kong publishes OpenAPI specifications for the Gateway Admin API, the Konnect AI Gateway API and the Konnect AI Catalog API, supports declarative configuration through decK, Terraform and the Kong Operator, and ships a Kong Konnect MCP Server so AI clients can manage Konnect through MCP tools.

Sourcedeveloper.konghq.com/llms.txtread 2026-09-22

Testing, Debugging & Optimization Full

Responses can be scored by a dedicated judge model through Kong's AI LLM as Judge plugin, which evaluates prompt and response pairs and gives each response a score from 1 to 100, with a configurable evaluator prompt, conversation history depth and sampling rate. Paired with AI Proxy Advanced's accuracy balancer, it compares responses from at least two models on live traffic, so customers get a readable score they can compare on their own traffic.

Browser & Computer Use Not documented

Browser and computer control sit outside what Kong AI Gateway does: it routes and governs model, MCP and agent traffic, and no browser, desktop or remote computer session it runs for an agent is documented. No headless fetch or third party engine is wired in either.

What is public

Kong publishes its Plus rate card, including $100 a month per model proxied through the AI Gateway, control plane charges and volume add-ons, alongside a 30-day free trial and custom Enterprise pricing.

Billing mechanics

Plus is self-serve and billed monthly, also purchasable through AWS Marketplace: gateway control planes carry monthly charges, the AI Gateway bills per unique LLM model proxied (prorated hourly, enforced monthly), and analytics, metering and identity bill by volume. Enterprise is annual and custom.

Cost watchouts

The AI Gateway bill grows with the number of distinct models proxied ($100 a month each on Plus), on top of gateway control plane charges and request add-ons, and the Plus plan caps AI Gateway at 5 unique models. RAG injection, LLM-as-judge and the semantic guard plugins are AI Gateway Enterprise plugins, add-ons on Plus.

Variable cost rationale

Graded medium rather than high because the open source core gives a genuinely free and self hostable entry point and the commercial model follows established API management norms rather than an invented agent consumption unit. The offsetting risks are that Kong sits in the path of all AI traffic so its cost tracks the very volume being governed, and that the tier boundary around agentic governance features was not retrieved.

Additional watchouts

Establish the tier boundary around the agentic capabilities early. The free gateway is not the AI Gateway, and the governance features that justify the purchase are the ones most likely to sit in the paid tier.

Overage / add-ons

AI Gateway models are prorated hourly and enforced monthly; API request volume above plan allowances is billed in 1 million request increments.

Sales call required

Mixed (some tiers require a call)

Free / trial

30-day free trial with Enterprise functionality, no credit card; open source Kong Gateway free to self-host

Lowest paid plan

Plus, billed monthly per gateway control plane; AI Gateway at $100 a month per unique model proxied, up to 5 models

Commercial notes

Kong is a long established API management vendor extending into AI connectivity, so it arrives with an existing enterprise commercial motion rather than a new one. Notably it also sells the tooling for customers to meter and monetize their own AI consumption.

Key ambiguities

The full cost of an AI Gateway deployment on Plus combines control plane, request and per-model charges; Enterprise terms are custom.

Missing data

Every commercial detail: Konnect tier pricing, enterprise licensing, and which AI and agent capabilities are gated behind which tier.
