Migrates the pullrequests toolset frommark3labs/mcp-go tomodelcontextprotocol/go-sdk. This is part of the broader SDK migration tracked in#1428.

Status

Migrated (2/10 tools):

• PullRequestRead - 6 methods (get, get_diff, get_status, get_files, get_review_comments, get_reviews)
• CreatePullRequest

Pending (8/10 tools): Commented out withTODO: MIGRATE THIS TOOL

• UpdatePullRequest, ListPullRequests, MergePullRequest, SearchPullRequests, UpdatePullRequestBranch, PullRequestReviewWrite, AddCommentToPendingReview, RequestCopilotReview

Changes

Tool definition pattern:

// Old DSL-basedfuncFoo(...) (mcp.Tool, server.ToolHandlerFunc) {returnmcp.NewTool("name",mcp.WithString("param",mcp.Required(),...),...    ),handler}// New JSON Schema-basedfuncFoo(...) (mcp.Tool, mcp.ToolHandlerFor[map[string]any,any]) {tool:= mcp.Tool{Name:"name",InputSchema:&jsonschema.Schema{Type:"object",Properties:map[string]*jsonschema.Schema{"param": {Type:"string",...},            },Required: []string{"param"},        },    }handler:= mcp.ToolHandlerFor[map[string]any,any](func(ctx context.Context,_*mcp.CallToolRequest,argsmap[string]any) (*mcp.CallToolResult,any,error) {// params extracted from args map        },    )returntool,handler}

Key signature changes:

• Handler:(ctx, request) (*Result, error) →(ctx, _, args map[string]any) (*Result, any, error)
• Parameter extraction:RequiredParam[T](request, "key") →RequiredParam[T](args, "key")
• Result construction:mcp.NewToolResultText() →utils.NewToolResultText()

Notes:

• get_comments method temporarily disabled (depends on unmigratedissues.go)
• Helper functions return(*Result, error), handlers return(*Result, any, error)
• search_utils.go updated to acceptargs map[string]any
