Migrates therepos toolset (18 tools) frommark3labs/mcp-go tomodelcontextprotocol/go-sdk as part of the broader SDK migration tracked in#1428.

Changes

Tool Definitions

• Converted frommcp.NewTool() DSL tomcp.Tool{} structs withjsonschema.Schema
• Changed tool handler signatures from(mcp.Tool, server.ToolHandlerFunc) to(mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])
• Updated handler functions to accept(ctx, *request, args) and return(result, data, error)

Before:

funcGetCommit(...) (mcp.Tool, server.ToolHandlerFunc) {returnmcp.NewTool("get_commit",mcp.WithString("owner",mcp.Required(),...),...    ),func(ctx context.Context,request mcp.CallToolRequest) (*mcp.CallToolResult,error) {owner,_:=RequiredParam[string](request,"owner")...returnmcp.NewToolResultText(data),nil    }}

After:

funcGetCommit(...) (mcp.Tool, mcp.ToolHandlerFor[map[string]any,any]) {tool:= mcp.Tool{Name:"get_commit",InputSchema:&jsonschema.Schema{Properties:map[string]*jsonschema.Schema{"owner": {Type:"string",...},            },Required: []string{"owner",...},        },    }handler:= mcp.ToolHandlerFor[map[string]any,any](func(ctx context.Context,_*mcp.CallToolRequest,argsmap[string]any) (*mcp.CallToolResult,any,error) {owner,_:=RequiredParam[string](args,"owner")...returnutils.NewToolResultText(data),nil,nil        })returntool,handler}

Parameter Extraction

• Changed fromRequiredParam[T](request, "key") toRequiredParam[T](args, "key")
• Updated optional parameter helpers to extract fromargs map[string]any

Result Types

• Replacedmcp.NewToolResultText/Error/Resource withutils.NewToolResultText/Error/Resource
• Unifiedmcp.TextResourceContents andmcp.BlobResourceContents intomcp.ResourceContents
• ChangedBlob field from base64 string to[]byte

Test Updates

• Updated all handler invocations to new 3-parameter, 3-return signature
• Added schema casting:schema := tool.InputSchema.(*jsonschema.Schema)
• Fixed resource content assertions for unified type

Toolsnaps

Updated 16 snapshot files reflecting schema format changes (property ordering, required array format).
