Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01171 | $0.01171 |
| Opus 5.5 | $0.00468 | $0.00468 |
| Sonnet 5.5 | $0.00234 | $0.00234 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade A, and why
raindrop-mcp GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Raindrop MCP Server - Project Context
Project Overview
This project is a Model Context Protocol (MCP) server for Raindrop.io, a bookmark management service. It allows AI assistants (like Claude or Gemini) to interact with a user's Raindrop bookmarks, collections, tags, and highlights using natural language.
The server supports both STDIO (standard input/output) and HTTP/SSE (Server-Sent Events) transports, making it compatible with various MCP clients including Claude Desktop and custom integrations.
Core Technologies
- Runtime: Bun (primary) / Node.js
- Language: TypeScript
- Frameworks:
@modelcontextprotocol/sdk: For MCP protocol implementation.zod: For input/output schema validation.express/node:http: For the HTTP/SSE transport layer.openapi-fetch: For Raindrop.io API communication.
- Testing:
bun test(Vitest compatible)
Architecture
The project follows a modular service-oriented architecture:
- Entry Points:
src/index.ts: Main entry point for the STDIO transport server.src/server.ts: Entry point for the HTTP/SSE server with session management and OAuth support.
- Core Service (
src/services/raindropmcp.service.ts):- Manages the
McpServerinstance. - Registers tools, resources, and prompts.
- Handles dynamic resource resolution.
- Manages the
- API Service (
src/services/raindrop.service.ts):- Encapsulates direct communication with the Raindrop.io API.
- Handles authentication (Access Token or OAuth).
- Tools (
src/tools/):- Modular tool definitions using
defineTool. - Categories:
bookmarks,collections,tags,highlights,diagnostics,bulk.
- Modular tool definitions using
- Resources:
- Dynamic resources for individual bookmarks (
mcp://raindrop/{id}) and collections (mcp://collection/{id}). - Static resources for user profile and server diagnostics.
- Dynamic resources for individual bookmarks (
- Prompts:
- Built-in prompts for complex workflows like "organize_by_topic" or "find_duplicates".
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
