Agent SDK for Go

Agent SDK for Go is an open-source SDK for building Go agents that can be exposed as A2A-compliant HTTP servers or connect remote A2A agents as tools for an LLM.

About this tool

Agent SDK for Go is designed for backend engineers, AI agent developers, and Go developers building interoperable agent systems.

Core Capabilities

  • A2A Server: Any agent can be exposed as a standards-compliant A2A (Agent-to-Agent) HTTP server.
  • A2A Client: Remote A2A agents can connect as tool providers for your LLM.
  • Sub-agents: In-process Go agents registered at build time that share the same deployment and runtime as the parent.
  • Dynamic Tool Management: Add or remove tools at runtime, swap MCP servers per tenant or user session, and register specialist sub-agents based on feature flags.

Use Cases

  • Expose an agent as a standards-compliant A2A HTTP server
  • Swap MCP servers per tenant or user session
  • Register specialist sub-agents dynamically based on feature flags
  • Add or remove tools for premium users at runtime
  • Connect remote A2A agents as tool providers for an LLM

Technical

Features The SDK supports budget controls (WithBudget, MaxCostUSD), run deadlines, hooks (AfterLLMHook, AfterMemoryStoreHook), and Temporal runtime integration. A2A is suited for connecting agents across services, languages, or teams; sub-agents are suited for in-process agents within the same deployment.

Best for
  • Backend engineers building interoperable agent systems
  • Go developers building AI agents
  • Teams connecting agents across services or languages
  • Scenarios requiring dynamic per-tenant or per-user tool and MCP server management
Use cases
  • Expose an agent as a standards-compliant A2A HTTP server
  • Swap MCP servers per tenant or user session
  • Register specialist sub-agents dynamically based on feature flags
  • Add or remove tools for premium users at runtime
  • Connect remote A2A agents as tool providers for an LLM
Strengths
  • Open-source and self-hosted
  • Public API available
  • A2A standard support for cross-service, cross-language agent interoperability
  • In-process sub-agents sharing the same deployment and runtime
  • Runtime dynamic tool and MCP server management
  • Temporal runtime integration with budget controls
Limitations
  • Pricing model is undisclosed
  • Medium learning curve
  • Requires self-hosted deployment
  • A WithBudget configured directly on a sub-agent is silently ignored when invoked from a parent (warning logged at runtime)
  • A mismatch between the agent and worker causes a fingerprint error on the Temporal runtime
