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 SDKs with built-in MCP server compatibility.
AgentRPC is a free, open-source AI agent RPC framework (Apache 2.0) with optional managed hosting (quote-based pricing) that lets AI agents call functions across private network boundaries without opening inbound ports. It solves a specific infrastructure problem: when your AI agent runs in one environment but needs to invoke functions inside a private VPC, Kubernetes cluster, or firewalled network, AgentRPC's outbound-only SDK connections bypass the need for VPNs, open ports, or ingress configuration entirely.
The framework ships native SDKs for 3 languages — TypeScript, Go, and Python — with a 4th (.NET) in active development as of early 2026. Each SDK uses long-polling to keep connections alive beyond the standard 30–60 second HTTP timeout, which is critical for agent tasks involving database queries, report generation, or multi-step data processing that run for several minutes. The TypeScript SDK includes a built-in MCP server that exposes registered functions to Claude Desktop, Cursor, and any MCP-compatible host without additional configuration, and all SDKs generate OpenAI-compatible tool definitions that work with Anthropic, LiteLLM, and OpenRouter.

Yes, AgentRPC is good for integrations work. Users particularly appreciate bridges network boundaries without vpn or port configuration — register functions from private vpcs, kubernetes clusters, and firewalled environments in minutes using outbound-only connections. However, keep in mind small user community with very few public production deployment examples or documented case studies as of early 2026 — limits available reference architectures.
Yes, AgentRPC offers a free tier. However, premium features unlock additional functionality for professional users.
AgentRPC is best for Private VPC Function Exposure: Teams with databases, ML models, or internal APIs in private VPCs who need AI agents to call those functions without opening inbound ports or configuring VPNs — the SDK's outbound-only connection model bypasses the network boundary problem entirely and Multi-Cloud Agent Orchestration: Organizations running services across AWS, GCP, and Azure who need a single RPC layer for agents to reach functions in any cloud environment without separate networking setups per cloud. It's particularly useful for integrations professionals who need universal rpc layer for cross-network function calling.
Popular AgentRPC alternatives include Temporal, Modal, Inngest. Each has different strengths, so compare features and pricing to find the best fit.
