Select Element Fix Summary
Problem Identified
The cremote MCP system had issues with select dropdown elements:
- Single
web_interact_cremotemcp
only supported "click", "fill", "submit", "upload" actions - missing "select" - Bulk
web_form_fill_bulk_cremotemcp
always used "fill" action, which tried to useSelectAllText()
andInput()
methods on select elements, causing errors - Multiple
web_interact_multiple_cremotemcp
already supported "select" action and worked correctly
Root Cause
- The "fill" action was designed for text inputs and used methods like
SelectAllText()
andInput()
- Select elements don't support these methods - they need
Select()
method or JavaScript value assignment - The daemon had proper select handling in the
interact-multiple
endpoint but not in single interactions or bulk form fill
Fixes Implemented
1. Enhanced Single Interaction Support
File: mcp/main.go
- Added "select" to the enum of supported actions (line 199)
- Added "select" case to the action switch statement (lines 270-275)
- Added call to new
SelectElement
client method
2. New Client Method
File: client/client.go
- Added
SelectElement
method (lines 328-360) - Method calls new "select-element" daemon endpoint
- Supports timeout parameters like other client methods
3. New Daemon Endpoint
File: daemon/daemon.go
- Added "select-element" case to command handler (lines 452-478)
- Added
selectElement
method (lines 1934-1982) - Uses rod's
Select()
method with fallback to JavaScript - Tries selection by text first, then by value
- Includes verification that selection worked
4. Enhanced Bulk Form Fill
File: daemon/daemon.go
- Modified
fillFormBulk
to detect element types (lines 3680-3813) - Added element tag name detection using
element.Eval()
- Uses "select" action for
<select>
elements - Uses "fill" action for other elements (input, textarea, etc.)
- Proper error handling for both action types
5. Updated Documentation
Files: mcp/LLM_USAGE_GUIDE.md
, mcp/QUICK_REFERENCE.md
, mcp/README.md
- Added "select" to supported actions
- Added examples for select dropdown usage
- Updated parameter descriptions
Testing Results
✅ Working Immediately (No Server Restart Required)

Test Examples
Single Select Action
web_interact_cremotemcp:
action: "select"
selector: "#country"
value: "United States" # Works with option text or value
Multiple Actions Including Select
web_interact_multiple_cremotemcp:
interactions:
- selector: "#firstName"
action: "fill"
value: "John"
- selector: "#state"
action: "select"
value: "California"
- selector: "#newsletter"
action: "check"
Bulk Form Fill (Auto-detects Select Elements)
web_form_fill_bulk_cremotemcp:
fields:
firstName: "John"
lastName: "Doe"
state: "CA" # Automatically uses select action
newsletter: "yes" # Automatically uses appropriate action
Verification
Tested on https://brokedown.net/formtest.php with:
- ✅ Select by option value ("CA", "TX", "FL")
- ✅ Select by option text ("California", "Texas", "Florida")
- ✅ Mixed form completion with 7 different field types
- ✅ All interactions successful (7/7 success rate)
