List proposals under proposals/, optionally filtered by
AI agents call list_proposals to retrieve information from Ebony Enriching without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only listing of proposals with optional filtering. It retrieves data without creating, modifying, deleting, or executing any operations. The append-only semantics and filesystem storage model of the server confirm that list operations are safe. Blast radius is minimal as the tool cannot alter state or trigger external effects.
From the tool's definition Tool name 'list_proposals' and description 'List proposals under `proposals/`' indicate a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
List proposals under proposals/, optionally filtered by. It is categorised as a Read tool in the Ebony Enriching MCP Server, which means it retrieves data without modifying state.
Register the Ebony Enriching MCP server in PolicyLayer and add a rule for list_proposals: 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 Ebony Enriching. Nothing to install.
list_proposals 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 list_proposals 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 list_proposals. 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.
list_proposals is provided by the Ebony Enriching MCP server (parkviewlab/ebony-enriching). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
