Search bookmarks with advanced filtering. This is the primary tool for finding bookmarks. Supports full-text search, tag filtering, date ranges, and collection scoping.
AI agents call bookmark_search to retrieve information from Raindrop Io MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries bookmark data based on search parameters (full-text search, tag filtering, date ranges, collection scoping). It has no side effects — it does not create, modify, delete, or execute any operations. It is a pure data retrieval function, placing it firmly in the Read category with low severity.
From the tool's definition Tool description states it "Search bookmarks with advanced filtering" and "finding bookmarks" — classic read-only operations. No mention of modification, deletion, or execution.

Search bookmarks with advanced filtering. This is the primary tool for finding bookmarks. Supports full-text search, tag filtering, date ranges, and collection scoping. It is categorised as a Read tool in the Raindrop Io MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Raindrop Io MCP Server MCP server in PolicyLayer and add a rule for bookmark_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 Raindrop Io MCP Server. Nothing to install.
bookmark_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 bookmark_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 bookmark_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.
bookmark_search is provided by the Raindrop Io MCP Server MCP server (kazuph/mcp-raindrop). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
