AI agents call list_factors to retrieve information from FactorHub 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 pure data retrieval tool that queries and returns market factor information with optional search/filter parameters. It has no side effects—it neither modifies data, executes code, deletes records, nor moves money. The blast radius of misuse is minimal; an AI agent cannot cause harm by listing available factors.
From the tool's definition Tool name 'list_factors' and description indicate it retrieves/queries a list of factors with metadata (factor codes, names, categories, annualized returns, Sharpe ratios).

Register the FactorHub MCP Server MCP server in PolicyLayer and add a rule for list_factors: 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 FactorHub MCP Server. Nothing to install.
list_factors 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_factors 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_factors. 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_factors is provided by the FactorHub MCP Server MCP server (michaelfeng/factorhub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
