AI agents call airbyte_get_stream_properties to retrieve information from Airbyte without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to fetch or query stream properties from an Airbyte connection without modifying them. While the description is empty (lowering confidence slightly), the naming pattern and server context (Airbyte manages data pipelines) indicate this retrieves metadata about streams rather than executing operations or modifying data. No destructive, financial, or code execution semantics are evident.
From the tool's definition Tool name 'airbyte_get_stream_properties' indicates retrieval of stream configuration/metadata properties. No description provided, but the 'get_' prefix and context of an Airbyte data integration platform strongly suggests read-only data retrieval.

airbyte_get_stream_properties. It is categorised as a Read tool in the Airbyte MCP Server, which means it retrieves data without modifying state.
Register the Airbyte MCP server in PolicyLayer and add a rule for airbyte_get_stream_properties: 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 Airbyte. Nothing to install.
airbyte_get_stream_properties is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the airbyte_get_stream_properties 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 airbyte_get_stream_properties. 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.
airbyte_get_stream_properties is provided by the Airbyte MCP server (trustxai/airbyte-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
