Kong Releases Volcano: A TypeScript, MCP-native SDK for Building Production Ready AI Agents with LLM Reasoning and Real-World actions

Kong has open-sourced Volcano, a TypeScript SDK that composes multi-step agent workflows across multiple LLM providers with native Model Context Protocol (MCP) tool use. The release coincides with broader MCP capabilities in Kong AI Gateway and Konnect, positioning Volcano as the developer SDK in an MCP-governed control plane.

  • Why Volcano SDK? because 9 lines of code are faster to write and easier to manage than 100+.
  • Without Volcano SDK? You’d need 100+ lines handling tool schemas, context management, provider switching, error handling, and HTTP clients. 
  • With Volcano SDK: 9 lines.

import { agent, llmOpenAI, llmAnthropic, mcp } from "volcano-ai";


// Setup: two LLMs, two MCP servers
const planner = llmOpenAI({ model: "gpt-5-mini", apiKey: process.env.OPENAI_API_KEY! });
const executor = llmAnthropic({ model: "claude-4.5-sonnet", apiKey: process.env.ANTHROPIC_API_KEY! });
const database = mcp("https://api.company.com/database/mcp");
const slack = mcp("https://api.company.com/slack/mcp");


// One workflow
await agent({ llm: planner })
 .then({
   prompt: "Analyze last week's sales data",
   mcps: [database]  // Auto-discovers and calls the right tools
 })
 .then({
   llm: executor,  // Switch to Claude
   prompt: "Write an executive summary"
 })
 .then({
   prompt: "Post the summary to #executives",
   mcps: [slack]
 })
 .run();

What Volcano provides?

Volcano exposes a compact, chainable API—.then(...).run()—that passes intermediate context between steps while switching LLMs per step (e.g., plan with one model, execute with another). It treats MCP as a first-class interface: developers hand Volcano a list of MCP servers, and the SDK performs tool discovery and invocation automatically. Production features include automatic retries, per-step timeouts, connection pooling for MCP servers, OAuth 2.1 authentication, and OpenTelemetry traces/metrics for distributed observability. The project is released under Apache-2.0.

Here are the Key Features of the Volcano SDK:

  • Chainable API: Build multi-step workflows with a concise .then(...).run() pattern; context flows between steps
  • MCP-native tool use: Pass MCP servers; the SDK auto-discovers and invokes the right tools in each step.
  • Multi-provider LLM support: Mix models (e.g., planning with one, execution with another) inside one workflow.
  • Streaming of intermediate and final results for responsive agent interactions.
  • Retries & timeouts configurable per step for reliability under real-world failures.
  • Hooks (before/after step) to customize behavior and instrumentation.
  • Typed error handling to surface actionable failures during agent execution.
  • Parallel execution, branching, and loops to express complex control flow.
  • Observability via OpenTelemetry for tracing and metrics across steps and tool calls.
  • OAuth support & connection pooling for secure, efficient access to MCP servers.

Where it fits in Kong’s MCP architecture?

Kong’s Konnect platform adds multiple MCP governance and access layers that complement Volcano’s SDK surface:

  • AI Gateway gains MCP gateway features such as server autogeneration from Kong-managed APIs, centralized OAuth 2.1 for MCP servers, and observability over tools, workflows, and prompts in Konnect dashboards. These provide uniform policy and analytics for MCP analytics.
  • The Konnect Developer Portal can be turned into an MCP server so AI coding tools and agents can discover APIs, request access, and consume endpoints programmatically—reducing manual credential workflows and making API catalogs accessible through MCP.
  • Kong’s team also previewed MCP Composer and MCP Runner to design, generate, and operate MCP servers and integrations.

Key Takeaways

  • Volcano is an open-source TypeScript SDK that builds multi-step AI agents with first-class MCP tool use.
  • The SDK provides production features—retries, timeouts, connection pooling, OAuth, and OpenTelemetry tracing/metrics—for MCP workflows.
  • Volcano composes multi-LLM plans/executions and auto-discovers/invokes MCP servers/tools, minimizing custom glue code.
  • Kong paired the SDK with platform controls: AI Gateway/Konnect add MCP server autogeneration, centralized OAuth 2.1, and observability.

Editorial Comments

Kong’s Volcano SDK is a pragmatic addition to the MCP ecosystem: a TypeScript-first agent framework that aligns developer workflow with enterprise controls (OAuth 2.1, OpenTelemetry) delivered via AI Gateway and Konnect. The pairing closes a common gap in agent stacks—tool discovery, auth, and observability—without inventing new interfaces beyond MCP. This design prioritizes protocol-native MCP integration over bespoke glue, cutting operational drift and closing auditing gaps as internal agents scale.
