rank_stocks
AI agents call rank_stocks to retrieve information from PM-MCP (Portfolio Management MCP Server) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
With no description available, classification relies on the tool name and server context. 'Rank' typically implies sorting/retrieving data with read-only semantics. The sibling tools (analytics_rank, analyze_dip_candidates_tool, backtest_strategy, chart_*) suggest this server emphasizes analysis and reporting rather than account modifications or financial transactions.
From the tool's definition Tool name 'rank_stocks' suggests a data retrieval/sorting operation that queries and ranks stock information.

rank_stocks. It is categorised as a Read tool in the PM-MCP (Portfolio Management MCP Server) MCP Server, which means it retrieves data without modifying state.
Register the PM-MCP (Portfolio Management MCP Server) MCP server in PolicyLayer and add a rule for rank_stocks: 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 PM-MCP (Portfolio Management MCP Server). Nothing to install.
rank_stocks 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 rank_stocks 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 rank_stocks. 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.
rank_stocks is provided by the PM-MCP (Portfolio Management MCP Server) MCP server (surplus96/pm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
