What is AgentRPC?

Open-source RPC framework (Apache 2.0) that lets AI agents call functions across network boundaries without opening ports. Supports TypeScript, Go, and Python with long-polling SDKs for long-running agent tasks.

AgentRPC: Let Your AI Agents Call Functions Anywhere

AI agents need to call functions. Sometimes those functions live behind a firewall, inside a Kubernetes cluster, or on a private VPC that the agent can't reach. AgentRPC solves this by providing a hosted RPC layer that bridges network boundaries. Your agent calls a function through AgentRPC's server; AgentRPC routes it to whatever machine registered that function. No open ports. No VPN configuration. No firewall rules.

Key Features

✓Universal RPC layer for cross-network function calling
✓No open ports required for function registration
✓Long-running function support via long polling
✓TypeScript, Go, Python SDKs (.NET coming)
✓Built-in MCP server for Claude Desktop and Cursor
✓OpenAI SDK-compatible tool definitions

Pros & Cons

✅Pros

  • •Bridges network boundaries without VPN or port configuration — register functions from private VPCs, Kubernetes clusters, and firewalled environments in two lines of code
  • •Long-polling SDKs solve HTTP timeout problems for agent tasks that run minutes, not seconds — critical for database queries and report generation
  • •Multi-language SDKs (TypeScript, Go, Python) let polyglot teams expose functions from all stacks through one unified RPC layer
  • •Built-in MCP server in TypeScript SDK means instant compatibility with Claude Desktop, Cursor, and any MCP-compatible host
  • •OpenAI-compatible tool definitions work with Anthropic, LiteLLM, and OpenRouter without modification
  • •Open-source under Apache 2.0 with managed hosting available — no vendor lock-in on the SDK side

❌Cons

  • •Small user community with very few public production deployment examples or documented case studies as of early 2026
  • •Documentation covers setup basics but lacks depth on security hardening, scaling patterns, and production deployment best practices
  • •Adds unnecessary complexity for publicly accessible tools — overkill when direct HTTP calls or standard MCP servers work fine
  • •Managed server adds a network hop that introduces measurable latency for sub-millisecond function calls
  • •.NET SDK still in development — teams using C# or F# cannot use AgentRPC yet

Who Should Use AgentRPC?

  • ✓Private VPC Function Exposure
  • ✓Multi-Cloud Agent Orchestration
  • ✓Polyglot Team Tool Integration
  • ✓Long-Running Agent Workflows

Who Should Skip AgentRPC?

  • ×You're concerned about small user community with very few public production deployment examples or documented case studies as of early 2026
  • ×You need advanced features
  • ×You need something simple and easy to use
