How to Set Up and Use Trpc MCP Go
trpc-mcp-go is a production-ready Go library from Tencent's tRPC team that implements the Model Context Protocol (MCP), enabling Go developers to build MCP servers and clients with full support for Streamable HTTP, Server-Sent Events (SSE), and STDIO transports. It provides type-safe schema generation, middleware support, progress notifications, and both stateful and stateless operation modes. Go backend developers and platform teams use it to build scalable MCP services that expose tools, resources, and prompt templates to AI models.
Prerequisites
- Go 1.21+ installed with a configured Go module workspace
- Basic familiarity with Go modules and the go get command
- An MCP client for testing (e.g., Claude Desktop, or the built-in MCP client in the library)
- Understanding of MCP concepts: tools, resources, and prompts
Add the library to your Go module
Install the trpc-mcp-go package into your Go project using go get.
go get trpc.group/trpc-go/trpc-mcp-goCreate a basic MCP server
Initialize a server with a name, version, and listening address, then start it. The server handles MCP protocol negotiation automatically.
package main
import (
"context"
"fmt"
mcp "trpc.group/trpc-go/trpc-mcp-go"
)
func main() {
s := mcp.NewServer(
"my-mcp-server",
"1.0.0",
mcp.WithServerAddress(":3000"),
mcp.WithServerPath("/mcp"),
)
s.Start(context.Background())
}Register a tool on the server
Define a tool with a name, description, and parameter schema, then register a handler function that the MCP client will invoke.
greetTool := mcp.NewTool("greet",
mcp.WithDescription("Greet a user by name"),
mcp.WithString("name", mcp.Description("The name to greet")),
)
s.RegisterTool(greetTool, func(ctx context.Context,
req *mcp.CallToolRequest) (*mcp.CallToolResult, error) {
name := req.Params.Arguments["name"].(string)
return mcp.NewTextResult(fmt.Sprintf("Hello, %s!", name)), nil
})Connect an MCP client to your server
Create a client instance pointing at your server's HTTP endpoint. The client can discover and call any registered tools.
client, err := mcp.NewClient(
"http://localhost:3000/mcp",
mcp.Implementation{Name: "my-client", Version: "1.0.0"},
mcp.WithProtocolVersion(mcp.ProtocolVersion_2025_03_26),
)
if err != nil {
panic(err)
}Enable STDIO transport for MCP client integration
For integration with MCP clients like Claude Desktop, run the server with STDIO transport instead of HTTP. Pass --transport=stdio when launching the binary.
s := mcp.NewServer(
"my-mcp-server",
"1.0.0",
mcp.WithStdioTransport(),
)Trpc MCP Go Examples

Example interactions once a trpc-mcp-go server is connected to an MCP client.
- "List all tools available on this MCP server"
- "Call the greet tool with the name 'Alice'"
- "Fetch the resource at uri://my-resource/data"
- "Use the summarize prompt template with the text 'Go is a statically typed language'"
- "Call the process_data tool and stream progress updates back to me"Troubleshooting Trpc MCP Go
go get fails with 'module not found' for trpc.group path
The module uses the trpc.group domain as its import path. Ensure you have internet access and no Go proxy is blocking external modules. If behind a corporate proxy, set GOPROXY=https://goproxy.io,direct or configure your proxy to allow trpc.group.
Client receives 'protocol version mismatch' error
Set the protocol version explicitly on the client using mcp.WithProtocolVersion(mcp.ProtocolVersion_2025_03_26). Ensure the server and client are using compatible versions. Check the library's changelog for supported protocol versions.
Tool handler panics when accessing Arguments map
Arguments values are interface{} and require type assertions. Always check if the key exists before asserting the type: if v, ok := req.Params.Arguments["name"]; ok { name := v.(string) }. Consider using the library's typed parameter helpers to avoid runtime panics.
