List all available PG-Git repositories stored in the database.
AI agents call pg_git_list_repos 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 metadata about repositories without modifying, executing, or deleting anything. It is a straightforward enumeration/discovery operation typical of Read category tools. The low severity reflects minimal blast radius: exposing repository names poses only informational risk.
From the tool's definition Tool name contains 'list' and description states 'List all available PG-Git repositories' — a query operation with no side effects.
Attacks that exploit this kind of access
List all available PG-Git repositories stored in the database. 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_list_repos: 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_list_repos 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_list_repos 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_list_repos. 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_list_repos 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.
