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 | $0.03822 | $0.03822 |
| Opus 5 | $0.01911 | $0.01911 |
| Sonnet 5 | $0.00764 | $0.00764 |
| Haiku 4.5 | $0.00382 | $0.00382 |
Grade A, and why
mcp-obsidian-via-rest CLAUDE.md scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Project Overview
This is an MCP (Model Context Protocol) server that provides access to Obsidian vaults via the Local REST API plugin. The server can run as a standalone Node/Bun application or as a Docker container, enabling AI assistants to read, search, and interact with Obsidian notes.
Multi-Transport Architecture:
- Transport Manager (
src/transports/manager.ts) - Manages lifecycle of multiple transport types - MCP Server Factory (
src/server/mcp-server.ts) - Creates MCP server instances with tools and resources - Transports:
stdio- Standard input/output transport (default, best for local MCP clients)http- HTTP JSON-RPC with streaming support (best for remote access)
- Self-Healing API (
src/api/self-healing.ts) - Automatic URL selection and reconnection - Configuration System (
src/config.ts) - Multi-URL and transport configuration

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.
