AI agents use connect_data_source to create or update resources in SuperDataAnalysis - DataMaster_MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SuperDataAnalysis - DataMaster_MCP environment.
The tool name indicates it creates or establishes a connection—a reversible configuration change rather than a destructive operation. While the empty description reduces confidence, the context of sibling tools managing API storage, sessions, and data imports suggests this tool modifies state by adding or linking a data source.
From the tool's definition Tool name 'connect_data_source' suggests establishing a connection to a data source, which is a state-modifying operation.
Documented attack patterns abuse exactly the kind of access connect_data_source gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SuperDataAnalysis - DataMaster_MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for connect_data_source:
{
"version": "1",
"default": "deny",
"tools": {
"connect_data_source": {
"limits": [
{
"counter": "connect_data_source_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}connect_data_source stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

connect_data_source. It is categorised as a Write tool in the SuperDataAnalysis - DataMaster_MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SuperDataAnalysis - DataMaster_ MCP server in PolicyLayer and add a rule for connect_data_source: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SuperDataAnalysis - DataMaster_MCP. Nothing to install.
connect_data_source is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the connect_data_source rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for connect_data_source. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
connect_data_source is provided by the SuperDataAnalysis - DataMaster_ MCP server (szqshan/datamaster-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SuperDataAnalysis - DataMaster_MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
