Get the status of the semantic search index.
AI agents call index_status to retrieve information from Frontmatter MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about an existing index. It performs a read-only operation that does not create, modify, delete, execute arbitrary code, or incur financial obligations. The action is purely informational with no blast radius if misused.
From the tool's definition Tool name 'index_status' and description 'Get the status of the semantic search index' indicate a query/retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get the status of the semantic search index. It is categorised as a Read tool in the Frontmatter MCP MCP Server, which means it retrieves data without modifying state.
Register the Frontmatter MCP server in PolicyLayer and add a rule for index_status: 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 Frontmatter MCP. Nothing to install.
index_status 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 index_status 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 index_status. 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.
index_status is provided by the Frontmatter MCP server (kzmshx/frontmatter-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
