使用 go 为法学硕士编写工具 - mcp-golang

package main

import (
    "fmt"
    mcp_golang "github.com/metoro-io/mcp-golang"
    "github.com/metoro-io/mcp-golang/transport/stdio"
    "io"
    "net/http"
)

    Latitude  float64 `json:"latitude" jsonschema:"required,description=The latitude of the location to get the weather for"`

// This is explained in the docs at https://mcpgolang.com/tools
