Maps all 27 source files and 55 tool registrations from github.com/modelcontextprotocol/go-sdk to github.com/mark3labs/mcp-go. Covers handler signature adapter, transport strategy, subsystem interface changes, and consumer impact. Key motivation: unlock SendNotificationToClient for claude/channel event push.

Architectural Decisions + +### 2a. Handler signature adapter + +The biggest change: every tool handler must change from 3-return generic to 2-return untyped. Two approaches: + +**Option A — Direct rewrite:** Change every handler to `func(ctx, mcp.CallToolRequest) (*mcp.CallToolResult, error)`. Manually unmarshal input from `request.Params.Arguments` and marshal output via `mcp.NewToolResultText(json)`. + +**Option B — Adapter pattern (recommended):** Write a generic adapter that preserves the current handler signatures: + +```go +// adaptHandler wraps a typed handler for use with mcp-go. +func adaptHandler[In, Out any](h func(ctx context.Context, req mcp.CallToolRequest, input In) (*mcp.CallToolResult, Out, error)) server.ToolHandler { + return func(ctx context.Context, req mcp.CallToolRequest) (*mcp.CallToolResult, error) { + var input In + data, _ := json.Marshal(req.Params.Arguments) + if err := json.Unmarshal(data, &input); err != nil { + return mcp.NewToolResultError("invalid input: " + err.Error()), nil + } + result, output, err := h(ctx, req, input) + if err != nil { + return nil, err + } + if result != nil { + return result, nil + } + // Marshal output to JSON text result + outJSON, _ := json.Marshal(output) + return mcp.NewToolResultText(string(outJSON)), nil + } +} +``` + +This lets us keep every handler's current signature (including the REST bridge) and migrates only the registration layer. The handler `req` param changes from `*mcp.CallToolRequest` (pointer) to `mcp.CallToolRequest` (value) — a minor type change. + +### 2b. Tool schema declaration + +Current approach uses `addToolRecorded` with reflection-based `structSchema()`. With mcp-go, two options: + +**Option A — Builder API:** Rewrite each tool's schema using `mcp.WithString(...)`, `mcp.WithNumber(...)`, etc. Tedious (40+ tools) but idiomatic. + +**Option B — Raw InputSchema (recommended):** `mcp.NewTool` accepts a raw `InputSchema` option. Feed the existing `structSchema()` output directly: + +```go +mcp.NewTool("file_read", + mcp.WithDescription("Read the contents of a file"), + mcp.WithRawSchema(structSchema(new(ReadFileInput))), +) +``` + +If `WithRawSchema` doesn't exist, the `mcp.Tool` struct likely has an `InputSchema` field we can set after construction. This preserves the reflection-based schema generation. + +### 2c. REST bridge (`addToolRecorded`) + +The `addToolRecorded` generic function currently: +1. Calls `mcp.AddTool(server, tool, handler)` — registers with MCP +2. Creates a `RESTHandler` closure — for the REST bridge +3. Reflects `In`/`Out` types for JSON Schema — for API docs + +With mcp-go, step 1 changes to `s.AddTool(tool, adaptHandler(h))`. Steps 2 and 3 remain unchanged. The `ToolRecord` struct and `RESTHandler` pattern are internal to our code, not SDK types. + +### 2d. TCP transport + +The official SDK exposes `mcp.Transport` and `mcp.Connection` interfaces. Our `connTransport` implements these. mcp-go doesn't have equivalent interfaces. Options: + +**Option A — Wrap stdio over TCP:** Pipe TCP conn's reader/writer into mcp-go's stdio transport. + +**Option B — Use StreamableHTTP:** Replace TCP with HTTP transport (mcp-go has built-in support). This is architecturally cleaner for multi-client scenarios. + +**Option C — Implement custom transport:** mcp-go's `server` package may expose transport interfaces. Investigate at implementation time. + +### 2e. Subsystem interface + +The `Subsystem` interface exposes `RegisterTools(server *mcp.Server)`. This must change to `RegisterTools(server *server.MCPServer)`. This is a **breaking change for consumers** (`agent`, `ide`). + +--- + +## 3.

00:00:00 2001 From: Snider Date: Sat, 21 Mar 2026 12:52:28 +0000 Subject: [PATCH 06/25] refactor(mcp): Options{} struct + notification broadcasting + claude/channel Phase 1: Replace functional options (WithWorkspaceRoot, WithSubsystem, WithProcessService, WithWSHub) with Options{} struct. Breaking change for consumers (agent, ide). Phase 2: Add notification broadcasting and claude/channel capability. - SendNotificationToAllClients: broadcasts to all MCP sessions - ChannelSend: push named events (agent.complete, build.failed, etc.) - ChannelSendToSession: push to a specific session - Notifier interface for sub-packages to avoid circular imports - claude/channel registered as experimental MCP capability Co-Authored-By: Virgil --- pkg/mcp/bridge_test.go | 10 +-- pkg/mcp/integration_test.go | 4 +- pkg/mcp/iter_test.go | 2 +- pkg/mcp/mcp.go | 117 ++++++++++++++----------------- pkg/mcp/mcp_test.go | 16 ++--- pkg/mcp/notify.go | 93 ++++++++++++++++++++++++ pkg/mcp/registry_test.go | 10 +-- pkg/mcp/subsystem.go | 30 +++++--- pkg/mcp/subsystem_test.go | 19 +++-- pkg/mcp/tools_metrics_test.go | 2 +- pkg/mcp/tools_process_ci_test.go | 2 +- pkg/mcp/tools_process_test.go | 4 +- pkg/mcp/tools_rag_ci_test.go | 12 ++-- pkg/mcp/tools_rag_test.go | 2 +- pkg/mcp/tools_webview_test.go | 4 +- pkg/mcp/tools_ws_test.go | 12 ++-- pkg/mcp/transport_e2e_test.go | 12 ++-- pkg/mcp/transport_tcp_test.go | 6 +- 18 files changed, 222 insertions(+), 135 deletions(-) create mode 100644 pkg/mcp/notify.go diff --git a/pkg/mcp/bridge_test.go b/pkg/mcp/bridge_test.go index a209e25..1db2a07 100644 --- a/pkg/mcp/bridge_test.go +++ b/pkg/mcp/bridge_test.go @@ -21,7 +21,7 @@ func init() { } func TestBridgeToAPI_Good_AllTools(t *testing.T) { -
