AI agents use updateConnection to create or update resources in SourceSync Ai MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SourceSync Ai MCP Server environment.
This tool modifies existing connection configurations and parameters reversibly. While it affects document ingestion settings and authorization flows, changes can be undone by updating the connection again. It does not delete data (Destructive), execute arbitrary code (Execute), or involve financial transactions (Financial).
From the tool's definition Tool description states 'Updates a connection' and mentions modifying 'connection to a different source', 'clientRedirectUrl', and 'pick a different or new set of documents' — all reversible modifications to configuration data.
Attacks that exploit this kind of access
Updates a connection to a specific source. The connector parameter should be a valid SourceSync connector enum value. The clientRedirectUrl parameter is optional and can be used to specify a custom redirect URL for the connection. This will give you a authorization url which you can redirect the user to. The user will then be asked to pick the documents they want to ingest. This is useful if you want to update the connection to a different source or if you want to update the clientRedirectUrl or if you want to pick a different or new set of documents. It is categorised as a Write tool in the SourceSync Ai MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SourceSync Ai MCP Server MCP server in PolicyLayer and add a rule for updateConnection: 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 SourceSync Ai MCP Server. Nothing to install.
updateConnection 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 updateConnection 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 updateConnection. 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.
updateConnection is provided by the SourceSync Ai MCP Server MCP server (scmdr/sourcesyncai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
