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 | $0.00263 | $0.00263 |
| Opus 5.5 | $0.00105 | $0.00105 |
| Sonnet 5.5 | $0.00053 | $0.00053 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade C, and why
obsidian-mcp copilot-instructions.md scanned grade C 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 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.

Adding New Tools
- Create a new file in
src/tools/ - Export a function that registers tools with the server
- Import and call the function in
src/index.ts
Key Dependencies
@modelcontextprotocol/sdk- Official MCP SDKzod- Schema validation for tool parameters
Build Commands
npm run build- Build the TypeScript projectnpm run dev- Watch mode for developmentnpm run start- Run the built servernpm run inspector- Test with MCP Inspector
Important Notes
- Use
console.error()for logging (stdout is reserved for MCP protocol messages) - Tool names should be lowercase with underscores
- Always validate inputs using Zod schemas
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.
