Fetch a list of available Snapshot spaces.
AI agents call list_spaces to retrieve information from Dao Proposals without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists available Snapshot spaces without side effects. It is a straightforward query operation that reads data from a DAO governance platform. The low severity reflects minimal risk—listing spaces does not expose sensitive financial data, execute code, or alter any state.
From the tool's definition Tool name 'list_spaces' and description 'Fetch a list of available Snapshot spaces' indicate a data retrieval operation with no modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Fetch a list of available Snapshot spaces. It is categorised as a Read tool in the Dao Proposals MCP Server, which means it retrieves data without modifying state.
Register the Dao Proposals MCP server in PolicyLayer and add a rule for list_spaces: 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 Dao Proposals. Nothing to install.
list_spaces 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_spaces 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_spaces. 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_spaces is provided by the Dao Proposals MCP server (kukapay/dao-proposals-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
