Get list of available legislative sessions. Returns sessions with session_id, years, and state info. Use session_id for subsequent bill lookups.
AI agents call legiscan_get_session_list to retrieve information from LegiScan MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval operation that queries legislative session metadata and returns results without any side effects. It enables lookups for subsequent operations but performs no writes, deletions, or code execution. The blast radius of misuse is minimal—an agent could only retrieve public legislative session information that is already publicly available.
From the tool's definition Tool returns session information (session_id, years, state info) with no modification capability. Description explicitly states 'Get list' indicating retrieval-only operation.

Register the LegiScan MCP Server MCP server in PolicyLayer and add a rule for legiscan_get_session_list: 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 LegiScan MCP Server. Nothing to install.
legiscan_get_session_list 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 legiscan_get_session_list 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.
