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 | $0.00363 | $0.00363 |
| Opus 5.5 | $0.00145 | $0.00145 |
| Sonnet 5.5 | $0.00073 | $0.00073 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
obsidian-mcp CLAUDE.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 2mo 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.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is the obsidian-mcp project, which appears to be intended as an MCP (Model Context Protocol) integration for Obsidian, the popular note-taking and knowledge management application.
Development Setup
As this is a new project, initial setup will be required:
- Initialize the project with appropriate package manager (likely npm/yarn for TypeScript/JavaScript)
- Set up the MCP server framework following the MCP specification
- Configure TypeScript if using (recommended for MCP servers)
- Set up testing framework (Jest, Vitest, or similar)
MCP Development Guidelines
When implementing MCP functionality:
- Follow the official MCP specification for server implementation
- Use the appropriate MCP SDK (@modelcontextprotocol/sdk for TypeScript)
- Implement proper error handling and validation for all MCP methods
- Ensure all tool responses follow the expected MCP format
Obsidian Integration Considerations
- Understand Obsidian's file structure (.md files, attachments, plugins folder)
- Respect Obsidian's metadata format (frontmatter YAML)
- Handle vault paths appropriately (cross-platform compatibility)
- Consider Obsidian's linking syntax ([[wikilinks]] and markdown links)
Permissions
The project has Claude CLI permissions configured in .claude/settings.local.json allowing:
lscommandsfindcommands
Additional permissions may need to be added as development progresses.
Future Development
Once the project structure is established, update this file with:
- Specific build and test commands
- Architecture decisions and patterns
- API documentation references
- Integration testing procedures
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.
