Get facts for a project version.
AI agents call df_get_facts to retrieve information from DataForge Semantic MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves fact metadata from DataForge for a given project version. There is no indication of data modification, deletion, or execution of arbitrary operations. The action is purely informational query with no side effects, consistent with Read category tools. No blast radius from misuse beyond potentially accessing metadata a user shouldn't see, which is a low-severity concern.
From the tool's definition Tool name 'df_get_facts' and description 'Get facts for a project version' indicate retrieval of metadata without modification. Consistent with sibling tools like 'df_get_dimensions', 'df_get_measures', and 'df_get_data_mart' which are read-only queries.

Get facts for a project version. It is categorised as a Read tool in the DataForge Semantic MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DataForge Semantic MCP Server MCP server in PolicyLayer and add a rule for df_get_facts: 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 DataForge Semantic MCP Server. Nothing to install.
df_get_facts 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 df_get_facts 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 df_get_facts. 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.
df_get_facts is provided by the DataForge Semantic MCP Server MCP server (sgromych/dataforge-mcp-gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
