### Upload Script
Save this script and run: `./upload-attachment.sh <file> <record_table> <record_id>`
Use `scripts/upload-attachment.sh` in this skill directory:
```bash
#!/bin/bash
# upload-attachment.sh - Upload file and link to Grist record
# Usage: ./upload-attachment.sh invoice.pdf Bills 13
# Get session token first (via MCP request_session_token tool)
# Then run:
./scripts/upload-attachment.sh invoice.pdf Bills 13
set -e
# Or pass token directly:
./scripts/upload-attachment.sh invoice.pdf Bills 13 sess_abc123...
FILE="$1"
TABLE="$2"
RECORD_ID="$3"
if [[ -z "$FILE" || -z "$TABLE" || -z "$RECORD_ID" ]]; then
echo "Usage: $0 <file> <table> <record_id>"
echo "Example: $0 invoice.pdf Bills 13"
exit 1
fi
# Get session token from Claude (copy from request_session_token response)
echo "Paste session token (from request_session_token MCP call):"
read -r TOKEN
# Base URL for the grist-mcp proxy
BASE_URL="https://grist-mcp.bballou.com"
# Upload attachment
echo "Uploading $FILE..."
RESPONSE=$(curl -s -X POST \
-H "Authorization: Bearer $TOKEN" \
-F "file=@$FILE" \
"$BASE_URL/api/v1/attachments")
# Extract attachment ID
ATTACHMENT_ID=$(echo "$RESPONSE" | jq -r '.data.attachment_id')
if [[ "$ATTACHMENT_ID" == "null" || -z "$ATTACHMENT_ID" ]]; then
echo "Upload failed: $RESPONSE"
exit 1
fi
echo "Uploaded: attachment_id=$ATTACHMENT_ID"
# Link to record via proxy
echo "Linking to $TABLE id=$RECORD_ID..."
curl -s -X POST \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d "{\"method\": \"update_records\", \"table\": \"$TABLE\", \"records\": [{\"id\": $RECORD_ID, \"fields\": {\"Attachment\": [\"L\", $ATTACHMENT_ID]}}]}" \
"$BASE_URL/api/v1/proxy" | jq .
echo "Done!"
# Environment variable for custom endpoint:
GRIST_MCP_URL=https://custom.example.com ./scripts/upload-attachment.sh ...
```
### Linking Attachments
Run `./scripts/upload-attachment.sh` without arguments for full usage.
Grist attachment columns use a special format: `["L", attachment_id]`
### Linking Attachments Manually
Grist attachment columns use format: `["L", attachment_id]`
```python
# Link attachment ID 1 to Bill ID 13
update_records("Bills", [{"id": 13, "fields": {"Attachment": ["L", 1]}}])
```
### Bills Table Attachment Column
| Column | Type | Notes |
|--------|------|-------|
| Attachment | Attachments | Stores invoice/receipt files |
