What is an API developer portal?

An API developer portal is a self-service platform where developers can discover APIs, access documentation, test APIs, generate credentials, and integrate APIs without engineering dependency.

Why is an API developer portal important?

An API developer portal improves API adoption by reducing onboarding friction, enabling faster integrations, and giving developers centralized access to APIs, documentation, sandboxes, and credentials.

Does DigitalAPI support multi-gateway API discovery?

Yes. DigitalAPI centralizes APIs from multiple gateways, repositories, and environments into one searchable developer portal.

Can developers test APIs directly inside the portal?

Yes. DigitalAPI provides interactive API sandbox and playground capabilities that allow developers to test APIs directly from the portal.

Is the DigitalAPI developer portal AI-ready?

Yes. DigitalAPI includes AI-powered search, API-GPT, and MCP-ready APIs to support both developers and AI agents.

For Agents · MCP Gateway is live in production

The Control Plane for AI Agent Execution!

Get one governed path, credential flow, and audit trail per team for agents calling private tools and internal APIs through MCP. The Enterprise MCP Gateway enforces default-deny policy, brokers credentials without exposing secrets, and records every decision. Hybrid or fully self-hosted.

Same APIs, Now Agent-Callable!

Different Teams, Different Use Cases, One Platform!

Platform & Integration Engineering

Make every API behind any gateway (Apigee, Kong, or AWS) agent-callable without a rebuild, so agents reach production in days, not months.

Director Platform · Argo Telecom

AI & Agent Engineering

Point agents at one endpoint (MCP gateway) and a registry of approved tools, so teams ship agents instead of rebuilding integrations and auth for every project.

Security, Governance & Compliance

Govern every agent-to-tool call with the same auth, scoping, and audit you already trust, so agentic AI clears security review and goes live.

Inside the gateway

Six Components. One Runtime.

DigitalAPI goes beyond presenting documentation. Every capability is built to drive real consumption, from first discovery to production integration.

accepted methods

Auth Handler

Maps MCP client identity to your existing key system. OAuth 2.1, API keys, mTLS issued from the same store your developers already use.

scopes × agents

RBAC Engine

Fine-grained scoping per agent, per tool and partner. Same policy model as your API portal, agents get exactly what their identity allows.

tool → endpoint

Proxy Router

Translates MCP tool calls into HTTP against your gateway. Preserves headers, propagates trace IDs, respects existing rate limits.

remote MCP servers

Tunnel Handler

Manages connections to remote MCP servers yours or third-party. Encrypted tunnels, connection pooling, automatic reconnect.

payments-v3 · versions

Subregistry

Source of truth for every tool, every version, every install. Searchable, queryable, exportable.

tool → endpoint

Tooling CLI ·MCP server

Translates MCP tool calls into HTTP against your gateway. Preserves headers, propagates trace IDs, respects existing rate limits.

Auto-generation

Every OpenAPI Spec Becomes a Tool

Point MCP Gateway at any API. It reads the spec, maps each operation to a Model Context Protocol tool, and preserves the descriptions, schemas and examples, so agents call your APIs correctly the first time.

No code changes. No engineering ticket. Promote any API to MCP-ready in a single click, the spec is the contract.

Live audit

Same Trace ID, Same Audit Pipeline!

Every MCP call goes through the same audit and metering as your HTTP API traffic. Compliance teams see one view, not two. Finance bills one pipeline.

Partner Agents

Partners' agents call your APIs as MCP tools, governed by partner-tier scopes.

Public Agent Devs

Pairs with · MCP Portal

The Runtime & The Storefront

MCP Gateway is the runtime, it executes tool calls, enforces auth, and emits audit. MCP Portal is the storefront where humans and agents discover those tools, install them, and read schemas.

Tool registry, public-facing: Every tool the gateway runs is browsable in the portal, versioned, searchable, with examples.

One-line install: For humans; standard MCP endpoint for agents.

Same keys, same audit: The keys issued in the Portal are the keys the Gateway authenticates.

APIs and MCP, side by side: Developers see one catalogue; agents see one tool registry.

Frequently asked questions

MCP Gateway, In Detail.

Do I need to migrate off my existing API gateway?

No. MCP Gateway sits beside Apigee, Kong, AWS Gateway or Azure APIM, it doesn't replace them. It calls them on behalf of agents through their existing public interfaces, so existing API traffic, policies and routing stay exactly as-is.

Where does the gateway run?

Self-hosted in your VPC (Helm chart or Docker), in a managed single-tenant region, or fully self-hosted on-prem for regulated environments. Traffic to your APIs never leaves your network, the gateway operates inside your trust boundary.

How is it priced?

MCP Gateway is included in the Growth plan ($8k/month) and Enterprise. Standalone licensing for the gateway alone (without the API Portal) is available. Talk to us.

Which agents/clients does it work with?

Anything that speaks the Model Context Protocol. That includes Anthropic's Claude, OpenAI's GPT (via Responses API tool calls), Google's Gemini, Cursor, Continue, and custom-built copilots.

What does an agent see when it connects?

A standard MCP server endpoint with a tool registry. Each tool has a name, description, input schema and example. Agents discover tools, read schemas, and call them as JSON-RPC requests, no Digital API SDK to install.
