What is granola-mcp-server AGENTS.md?

Project instructions for a TypeScript server that connects AI assistants to Granola meeting data, including notes and transcripts. They describe the project's structure, tools, and main source files.

Use them when changing or reviewing the Granola MCP server, its API connection, authentication, Markdown conversion, or TypeScript build.

They give a coding agent the background needed to work consistently in this specific project.

Token cost

What it costs to keep this loaded

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	$0.01465	$0.01465
Opus 5	$0.00732	$0.00732
Sonnet 5	$0.00293	$0.00293
Haiku 4.5	$0.00146	$0.00146

Measured 10d ago against content hash 07c02d599d6f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade A, and why

granola-mcp-server AGENTS.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 10d 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 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.
