File Transfer
SkillFiles & storageImplement data transmission between the local computer and the MCP Server using Base64 encoding
Available today. Use it from your connected AI after setup.
No other account needed.
Connect ahel once, and every AI you use reads what you have installed.
Then ask your AI: use the File Transfer skill
What this skill tells your AI
The instructions your AI receives, as published by internscience/molclaw in skills/L1_tools/molclaw-file-transfer/SKILL.md and read by ahel’s review.
Note:
- Local files are not directly accessible by the server. Please upload them to the server using
molclaw-file-transferbefore execution. - For PDB file inputs, it is recommended to preprocess them using
molclaw-pdbfixerbefore execution. - Please refer to skill
molclaw-scp-serverto complete tool invocation.
1. Transfer local file to SCP server
Example code:
import base64
client = DrugSDAClient("https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool")
if not await client.connect():
print("connection failed")
return
## Convert local file to base64 string
local_file = "/path/a.txt" #Input local file path
with open(local_file, "rb") as f:
file_content = f.read()
file_base64_string = base64.b64encode(file_content).decode('utf-8')
## Call tool base64_to_server_file to save base64 string as server file
response = await client.session.call_tool(
"base64_to_server_file",
arguments={
"file_name": "a.txt",
"file_base64_string": file_base64_string
}
)
result = client.parse_result(response)
save_file = result["save_file"] #Server file path after transfer
await client.disconnect()
2. Transfer SCP server file to local
Example code:
import base64
client = DrugSDAClient("https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool")
if not await client.connect():
print("connection failed")
return
## Call tool server_file_to_base64 to convert server file to base64 string
response = await client.session.call_tool(
"server_file_to_base64",
arguments={
"file_path": "/path/a.txt" #Input server file path
}
)
result = client.parse_result(response)
base64_string = result["base64_string"]
file_name = result["file_name"]
## Convert base64 string to local file
file_data = base64.b64decode(base64_string)
local_file_path = "/path/" + file_name
with open(local_file_path, "wb") as f:
f.write(file_data)
await client.disconnect()
