Semantically search the contents of all files in PG-Git. Results are automatically decayed by age so recent code ranks higher.
AI agents call pg_git_semantic_search to retrieve information from PG-Git (Semantic Memory MCP) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and ranks data from stored files without creating, modifying, deleting, or executing operations. Semantic search with decay ranking is a read-only analytical operation with minimal blast radius—worst case is returning unexpected search results or information disclosure, not data mutation or external side effects.
From the tool's definition Tool performs semantic search across file contents with time-decay ranking. Description indicates retrieval/query operation ('semantically search') with no modification, deletion, or execution capabilities.

Semantically search the contents of all files in PG-Git. Results are automatically decayed by age so recent code ranks higher. It is categorised as a Read tool in the PG-Git (Semantic Memory MCP) MCP Server, which means it retrieves data without modifying state.
Register the PG-Git (Semantic Memory MCP) MCP server in PolicyLayer and add a rule for pg_git_semantic_search: 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 PG-Git (Semantic Memory MCP). Nothing to install.
pg_git_semantic_search 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 pg_git_semantic_search 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 pg_git_semantic_search. 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.
pg_git_semantic_search is provided by the PG-Git (Semantic Memory MCP) MCP server (kruschdev/pg-git-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
