Performs a keyword search across all files in the vault.
AI agents call search to retrieve information from Obsidian Modified without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Searching is a retrieval operation with no side effects. It queries existing data without creating, modifying, deleting, or executing anything. The most severe risk is information disclosure of vault contents, which is inherent to any search function and poses minimal blast radius if an agent misuses it.
From the tool's definition Tool performs keyword search across vault files. Description explicitly states 'search' operation with no mention of modification, deletion, or execution.

Attacks that exploit this kind of access
Performs a keyword search across all files in the vault. It is categorised as a Read tool in the Obsidian Modified MCP Server, which means it retrieves data without modifying state.
Register the Obsidian Modified MCP server in PolicyLayer and add a rule for 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 Obsidian Modified. Nothing to install.
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 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 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.
search is provided by the Obsidian Modified MCP server (@marwansaab/obsidian-modified-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
