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 | $0.00017 | $0.00801 |
| Opus 5 | $0.00009 | $0.00400 |
| Sonnet 5 | $0.00003 | $0.00160 |
| Haiku 4.5 | $0.00002 | $0.00080 |
Grade A, and why
mcp-refactoring 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 7d 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.

MCP Refactoring Skill
Guidelines for refactoring Raindrop MCP tools for better LLM integration, usability, and following MCP best practices.
Capabilities: Resources, Sampling, Elicitation
Resources
Expose all major Raindrop entities as MCP resources:
collections://all,collections://{id}bookmarks://{id},tags://allhighlights://all,user://info
Implement resource discovery and navigation (list, get, search, children, etc.) using standard MCP resource URIs and methods. Ensure each resource supports GET (read), and where appropriate, CREATE, UPDATE, DELETE (write) actions.
Sampling
For large collections/bookmarks/tags/highlights, implement sampling endpoints:
- e.g.,
bookmarks://collection/{id}?sample=10returns a random or recent sample. - Add tool parameters for limit, offset, and sample to all list/search tools.
- Use MCP's sampling capability to advertise this in the server manifest.
Elicitation
Implement elicitation tools for:
- Confirming destructive actions (delete, merge, etc.)
- Requesting missing parameters (e.g., if a required field is omitted, prompt the LLM/user)
- Use the MCP elicitation capability to allow the server to ask clarifying questions or confirmations.
Streamlining Tools for LLMs
Hierarchical, Predictable Naming
- Use a consistent
{resource}_{action}pattern (e.g.,collection_list,bookmark_create,tag_manage) - Group related actions under a single tool with an operation parameter where possible (e.g.,
collection_managefor create, update, delete)
Reduce Redundancy
Collapse similar tools:
- Merge
collection_create,collection_update,collection_deleteintocollection_managewith an operation parameter - Do the same for bookmarks, tags, highlights
- For read-only actions, keep list, get, and search as separate, simple tools
LLM-Friendly Descriptions
- Ensure every tool and parameter has a clear, concise description
- Use Zod schemas for validation and documentation
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.

mcp-refactoring is a skill published in the GitHub repository adeze/raindrop-mcp (183 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 801 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
