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 | $0.03223 | $0.03223 |
| Opus 5.5 | $0.01289 | $0.01289 |
| Sonnet 5.5 | $0.00645 | $0.00645 |
| Haiku 4.5 | $0.00322 | $0.00322 |
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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
An MCP (Model Context Protocol) server that provides LLM access to git-backed Obsidian vaults. The server supports three deployment modes: stdio (local), HTTP (local with OAuth), and AWS Lambda (remote with OAuth + DynamoDB).
Workspace Structure
This is an npm workspace monorepo with two packages:
packages/app- Core MCP server implementation (stdio, HTTP, Lambda handlers)packages/cdk- AWS CDK infrastructure stack for Lambda deployment
Development Commands

npm run build
# Build specific bundles
npm run build:app # All app bundles
npm run build:lambda # Lambda bundle only
npm run build:cdk # CDK infrastructure
# Clean build artifacts
npm run clean
Running Locally
# Stdio mode (for Claude Desktop, Cursor)
npm run dev
# HTTP mode with OAuth (for ChatGPT, remote clients)
npm run dev:http
Testing
# Run all tests
npm test
# Watch mode
npm run test:watch
Linting & Formatting
# Lint TypeScript files
npm run lint
npm run lint:fix
# Format all files
npm run format
npm run format:check
AWS Deployment
# Synthesize CloudFormation template
npm run cdk:synth
# Deploy to AWS
npm run cdk:deploy
# Destroy stack
npm run cdk:destroy
Architecture
Core Concepts
VaultManager Interface: Abstract interface for vault operations (read, write, delete, move files). Implemented by GitVaultManager which handles git clone/pull/commit/push automatically.
Transport Modes: The MCP server supports two transports selected at runtime:
- Stdio: Standard input/output for local MCP clients (no OAuth)
- HTTP: Streamable HTTP with OAuth 2.0 for remote access
Three Server Implementations:
packages/app/src/server/local/stdio.ts- Local stdio mode with pre-configured credentialspackages/app/src/server/local/http.ts- Local HTTP mode with in-memory session storagepackages/app/src/server/lambda/index.ts- Lambda handler with DynamoDB session storage
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.
