# Go MCP Operator Runbook
This runbook is for the first Go MCP phase of `isphere-ai-bridge`. It lets an operator build and verify the Windows helper and the Go MCP server without reading the source code.
Current scope: expose four read-only WinHelper operations through Go MCP. This phase does not automate iSphere login and does not perform message or file actions.
## 1. Prerequisites
Run all commands from the repository root:
```powershell
cd E:\coding\codex\isphere-ai-bridge
```
Required local tools:
- Windows PowerShell.
- .NET Framework C# compiler used by `scripts\build-win-helper.ps1`.
- Go toolchain compatible with this module.
- A normal user desktop session; administrator rights are not required for the first phase.
Python is not required. Python MCP is not part of this path.
## 2. Build C# helper
The C# helper is the Windows/UI Automation execution layer. Build it with:
```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File scripts\build-win-helper.ps1
```
Expected output includes `"ok":true` and writes:
```text
runs\win-helper\ISphereWinHelper.exe
```
## 3. Verify C# helper
Run the helper verification script:
```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-win-helper.ps1
```
Expected output includes `"ok":true`, helper version `0.1.0`, a window scan count, and a UIA availability value.
## 4. Build Go MCP
Run tests first:
```powershell
go test ./...
```
Build the Go MCP binary:
```powershell
go build ./cmd/isphere-mcp
```
This creates the platform default binary in the repository root, for example:
```text
isphere-mcp.exe
```
If you want a fixed operator path, use an explicit output path instead:
```powershell
go build -o runs\go-mcp\isphere-mcp.exe ./cmd/isphere-mcp
```
## 5. Verify Go MCP
Run the repeatable smoke verification:
```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-go-mcp.ps1
```
Expected final output includes:
```json
{"ok":true}
```
The verification confirms:
- C# helper can be built.
- Go MCP binary can be built.
- MCP initialize/list/call flow works through the SDK harness.
- Exactly four tools are exposed.
- `win_helper_version` returns `ISphereWinHelper`.
- No real iSphere login is required.
- No message/file/search action tool is present.
## 6. Configure MCP client command
After building a stable binary, configure your MCP client to run the Go MCP executable as a stdio server.
Recommended command if using the fixed output path:
```text
E:\coding\codex\isphere-ai-bridge\runs\go-mcp\isphere-mcp.exe
```
Recommended working directory:
```text
E:\coding\codex\isphere-ai-bridge
```
Example client configuration shape:
```json
{
"mcpServers": {
"isphere-ai-bridge": {
"command": "E:\\coding\\codex\\isphere-ai-bridge\\runs\\go-mcp\\isphere-mcp.exe",
"cwd": "E:\\coding\\codex\\isphere-ai-bridge"
}
}
}
```
If you used `go build ./cmd/isphere-mcp` without `-o`, point the command to:
```text
E:\coding\codex\isphere-ai-bridge\isphere-mcp.exe
```
## 7. Allowed tools
Only these four tools are allowed in the first phase:
| Tool | Helper op | Purpose |
| --- | --- | --- |
| `win_helper_version` | `version` | Read helper version and protocol metadata. |
| `win_helper_self_check` | `self_check` | Read desktop/UIA availability status. |
| `win_helper_scan_windows` | `scan_windows` | Read visible window metadata or likely iSphere candidates. |
| `win_helper_dump_uia` | `dump_uia` | Read a UI Automation tree for a specified window handle. |
Allowed parameters:
- `win_helper_version`: no business parameters.
- `win_helper_self_check`: no business parameters.
- `win_helper_scan_windows`: `include_all_visible` only.
- `win_helper_dump_uia`: `hwnd`, `max_depth`, `include_text`, `max_children` only.
## 8. Explicit non-goals and safety boundaries
The current phase has these boundaries:
- no login automation
- no send message
- no send file
- no receive/download file
- no process injection
- no hook
- no memory reading
- no search contacts
- no open conversation
- no automatic login
- no credential, token, cookie, or private-key extraction
- no endpoint-security bypass or evasion
- no Python MCP fallback
Future send/file operations, if ever approved, must be behind explicit human approval and audit records. They are not implemented in this phase.
## 9. Real-login UIA capture procedure
This is a later real-login capture gate. Do not run it unless the operator has explicit approval for the real logged-in UIA capture step.
Procedure:
1. Build and verify first:
```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-win-helper.ps1
powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-go-mcp.ps1
```
2. Manually open iSphere / IMPlatformClient.
3. Manually log in using the normal company-approved process.
4. Keep the main iSphere window visible.
5. Use `win_helper_scan_windows` to find the candidate window. Prefer read-only scan arguments such as:
```json
{ "include_all_visible": true }
```
6. Use `win_helper_dump_uia` on the selected `hwnd`, for example:
```json
{
"hwnd": "0x001A0B2C",
"max_depth": 8,
"include_text": true,
"max_children": 80
}
```
7. Save approved evidence under:
```text
runs\real-loggedin-lab\uia-dumps\
```
8. Review and redact any sensitive content before sharing reports.
During this procedure, the operator must not click, type, send, upload, download, modify client state, or capture passwords/tokens.
## 10. If this environment cannot log in
Do not run or mark the real-login UIA capture gate as passed.
If login is only possible in another test sandbox, follow `docs/offline-evidence-intake-plan.md` and use the recommended **Full sandbox artifact bundle** route. The user does not need to generate JSON. Ask them to copy the logged-in test sandbox's install directory, user-data directories, ProgramData directories, shortcuts, `%TEMP%\importal` / `localcache` candidates, and simple copy notes into `runs\offline-evidence-intake\<evidence-id>\`.
The minimal `manifest.json` / `scan_windows-redacted.json` / `dump_uia-main-redacted.json` route is optional and only for advanced operators. In either route, the package is `N12-pre` context only. It can support offline inventory and reverse analysis, but it does not replace live current-environment `win_helper_scan_windows` and `win_helper_dump_uia` evidence.
After receiving a full bundle, first do read-only inventory. Do not directly run unknown copied binaries, do not modify original copied files, do not use copied credential-like material to log in, and do not design automatic login, send message, send file, receive file, injection, hook, memory reading, or endpoint-security bypass behavior.
## 11. Troubleshooting
- If C# helper build fails, run `scripts\build-win-helper.ps1` directly and check for missing .NET Framework reference assemblies.
- If `win_helper_version` fails, rerun `powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-win-helper.ps1` first.
- If Go MCP verification fails, rerun `go test ./...` and `powershell -NoProfile -ExecutionPolicy Bypass -File scripts\verify-go-mcp.ps1`.
- If a client cannot start the MCP server, confirm the configured command points to the built `.exe` and the working directory is the repository root.
