Why use it
You’re deep in a coding session and need to check that product decision you dictated yesterday. With Letterly MCP in Claude Code, you don’t leave the terminal — just ask, and your notes are there.
Record architecture ideas on a walk, meeting decisions on the go, or quick reminders between sessions. Claude Code pulls them in as context when you need them.
Setup
Run this single command in your terminal:
Claude Code will open a browser window for you to sign in to Letterly. After that, the connector is saved — it works in every future session automatically.
Verify the connection
Run claude mcp list to check that letterly appears in your connected servers.
Remove if needed
Try these prompts
Pull context from notes
Find my notes about the API redesign and use them as context for this refactor
What did I say about the auth flow in my recent notes?
Capture decisions
Save a note: decided to use PostgreSQL instead of MongoDB for the user service, reasons: ACID compliance, existing team expertise
Rewrite notes into docs
Take my last voice note about the deployment process and turn it into a README section
Search during code review
Check my notes for any discussion about rate limiting before I review this PR
Workflows
Morning standup prep
Record a quick voice note at the end of each day summarizing what you worked on. Next morning, ask Claude Code to pull up yesterday’s note and draft your standup update.
Architecture decision records
Dictate your reasoning while it’s fresh — on a walk, after a meeting, wherever. Later, ask Claude Code to find those notes and format them into an ADR.
Bug context
When you spot an issue but can’t fix it right now, record a voice note with the details. When you’re ready to fix it, ask Claude Code to search your notes and it will have the full context.
