Get project foundations (compressed learnings). Foundations are promoted from repeated pressure events. They represent project-specific defaults with confidence levels (0-3). Query by context tags or minimum confidence to get relevant foundations.
AI agents call get_foundations to retrieve information from Decision OS MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_foundations retrieves compressed learnings and project-specific defaults from a knowledge base. The action is read-only, with no side effects, data creation, modification, deletion, or execution of external operations. Confidence is high because the description clearly indicates a query/retrieval operation.
From the tool's definition Tool description states 'Get project foundations' and 'Query by context tags or minimum confidence' — purely retrieves/queries data with no modification or execution capability.

Get project foundations (compressed learnings). Foundations are promoted from repeated pressure events. They represent project-specific defaults with confidence levels (0-3). Query by context tags or minimum confidence to get relevant foundations. It is categorised as a Read tool in the Decision OS MCP MCP Server, which means it retrieves data without modifying state.
Register the Decision OS MCP server in PolicyLayer and add a rule for get_foundations: 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 Decision OS MCP. Nothing to install.
get_foundations 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 get_foundations 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 get_foundations. 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.
get_foundations is provided by the Decision OS MCP server (marianstefi20/decision-os-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
