Krewbill MCP
Krewbill gives each client a shared AI memory: a space of notes that a person has approved. Claude, ChatGPT and Cursor read those notes over a remote MCP server, so your team stops re-explaining a client's tone, rules and facts in every new chat.
Website: https://krewbill.com
This repository only describes the hosted Krewbill MCP service. The service itself is closed-source.
What it does
- One space per client, holding notes a person has approved.
- Assistants can read a space's approved notes.
- Assistants can only suggest new notes. Nothing is saved to the space until a person approves it.
- Each connection key is limited to the spaces you choose, can be read-only, and can be revoked.
- Accounts, workspaces, roles and invitations are available in the web app.
- Works with any MCP client that supports remote (HTTP) servers. Tested with Claude Code; use with other clients may need a different setup.
Tools
| Tool | What it does |
|---|---|
list_spaces | Lists the spaces your key may read. |
get_space_context | Returns a space's approved notes (voice and rules, key facts, decisions). Assistants call it first, before drafting for a client or project. |
search_memory | Searches approved notes by keyword, in one space or in all spaces your key can read. |
suggest_memory | Proposes a new note. It waits in an approval queue until a person approves it, and never changes shared memory by itself. |
flag_stale | Flags an approved note as possibly out of date for a person to review. It never edits or removes the note. |
A key can cover one space, several, or all of them, and can be read-only. Read-only keys cannot suggest notes.
Connect
- Create a space and a connection key at https://krewbill.com (see https://krewbill.com/connect).
- Krewbill shows your personal server address once, when you create the key. Copy it.
- Add it to your assistant. For Claude Code:
claude mcp add --transport http krewbill <your-server-address>
If your tool asks for a header instead of a key in the address, use the plain server address https://www.krewbill.com/api/mcp and send Authorization: Bearer <your-key>.
Create one key per tool, so you can revoke each separately.
Status
Krewbill is free during early access, until December 30, 2026. Connections authenticate with keys.
