Get the current schema (columns, types, codecs) for a stream
AI agents call conduit_get_schema to retrieve information from Conduit MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about a data stream's structure (columns, types, codecs). It is a read-only query operation that does not create, modify, delete, or execute anything. The blast radius of misuse is minimal — an AI agent could learn about stream schemas but cannot alter data or trigger external operations. This is a straightforward Read category tool.
From the tool's definition Tool name is 'conduit_get_schema' and description states it 'Get[s] the current schema (columns, types, codecs) for a stream' — purely a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get the current schema (columns, types, codecs) for a stream. It is categorised as a Read tool in the Conduit MCP MCP Server, which means it retrieves data without modifying state.
Register the Conduit MCP server in PolicyLayer and add a rule for conduit_get_schema: 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 Conduit MCP. Nothing to install.
conduit_get_schema 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 conduit_get_schema 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 conduit_get_schema. 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.
conduit_get_schema is provided by the Conduit MCP server (useconduit/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
