How to Give Your Whole Team Shared Claude Memory and Context
A practical guide to shared Claude memory and context for teams, using Notion, Composio, and supermemory.ai without sharing API keys.
What does “shared Claude memory” actually mean for a team?
Shared Claude memory means every person on a team can work inside Claude with access to the same documents, the same connected tools, and the same accumulated context, without logging into one shared account or passing around API keys. By default, Claude’s memory is tied to a single account, third-party memory tools save findings locally on one machine, and MCP (Model Context Protocol) connections authenticate as one individual user. None of that was built for teams. A workable alternative combines a shared document layer, a shared tool-access layer, and a shared memory layer, stitched together using tools most teams already have.
TL;DR
- Claude was built single-player: memory is per-account, MCP connectors authenticate individually, and most third-party memory tools store data locally, so teams get no shared context by default.
- Notion (or any permissioned drive) can act as the source of truth, giving Claude a shared context layer with permissions already built in, so nobody has to hand-copy Claude.md files between machines.
- Composio lets a team share tool access without sharing API keys, connecting Claude to over a thousand apps while each person authenticates with their own login.
- A gateway layer inside Composio can scope access to a single tool or account, useful for rare cases like a shared social media login with no individual seats.
- supermemory.ai adds a queryable shared memory layer, so decisions and context from one person’s Claude session become retrievable by teammates instead of getting lost in a single chat history.
- The whole setup uses existing consumer tools, not custom infrastructure, which means a non-technical team can maintain most of it, aside from one more advanced permission trick.

Why doesn’t Claude support team memory out of the box?
Claude’s architecture treats context as something an individual account owns. Memory saved in one person’s Claude is invisible to a colleague using their own account. MCP connectors, the protocol Claude uses to talk to outside apps, also authenticate per user, so connecting Gmail or a CRM through Claude’s built-in connectors ties that connection to whoever set it up.
This gap isn’t unique to Claude. Y Combinator has listed team infrastructure for AI agents as an open problem on its requests for startups, an indication that shared context and permissions across a team remain unsolved at the infrastructure level. Teams currently patch around it by copying Claude.md files and project folders across machines, which works briefly but decays fast because nobody consistently keeps every copy in sync. Using GitHub is another workaround, but it assumes technical comfort that most business users don’t have.
How do you build a shared context layer for Claude?
The fix is to stop storing context in files that live on individual machines and instead point Claude at a shared, permissioned source that already exists in most workplaces, like Notion, Google Drive, or another cloud document tool. Notion works well here because it already solves two problems at once: it’s a shared drive multiple people can edit, and it has granular permissions built in.
The setup works like this:
- Each team member connects Claude to Notion individually through Settings, then Connectors, using the built-in Notion connector. This authenticates with their own login, so Claude only ever reads what that person already has permission to see in Notion.
- Documents inside Notion, things like brand guidelines, contact lists, or a company voice profile, get normal Notion permission settings: full edit access for some, view-only for others, private for a restricted group.
- The Notion page URL gets referenced directly in Claude’s instructions or in a Claude.md file, with a line telling Claude to check that URL first when looking for team context.
Because permissions are enforced by Notion itself, there’s no separate permission system to build or maintain. Change a page’s sharing setting once, and it updates what Claude can see for that person automatically.
How can a team share tools in Claude without sharing API keys?
Sharing API keys across a team creates obvious problems: keys get passed around insecurely, and when someone leaves, every key they touched needs to be revoked and reissued. A cleaner approach uses a connector platform like Composio as a middle layer between Claude and outside apps, so the key lives in one place while each person authenticates as themselves.
This works in two layers.
Built like a system. Not vibe-coded.

Personal accounts. Each team member adds Composio as a custom connector in Claude (Settings, Connectors, add a custom connector, with the Composio remote MCP server URL) and signs in with their own Composio login. Once added to the team’s workspace, that single connector gives Claude access to Composio’s full library of supported apps, over a thousand at last count. Each person connects their own individual accounts, such as their own Gmail inbox, inside that workspace. No key ever leaves Composio’s vault, and each person is only ever acting as themselves.
Shared accounts. For things like a company inbox or accounting software where multiple people legitimately need access, the simplest method is to give each person a proper seat inside that app (in tools like Xero, for example) and let those permissions pass through when they sign in via Composio. For rarer cases, like a shared social media login with no individual seats available, Composio’s MCP gateway can scope access down to just one tool or account and generate a dedicated MCP URL for it. That URL then gets added to Claude as its own custom connector, giving a person access to just that scoped resource. This step is more technical and isn’t available directly in the Composio dashboard yet, but it covers edge cases the simpler method can’t.
Composio’s pricing structure includes a free tier (20,000 tool calls per month, three team members) and a paid tier at $29 a month for 50,000 tool calls with unlimited team members, which covers most small teams without much friction.
Is shared memory harder to solve than shared documents or tools?
Yes, and it’s arguably the more valuable piece. Documents and tools are static or semi-static, but memory is about capturing what a team learns while working, the reasoning behind decisions, not just the decisions themselves. Claude’s built-in memory doesn’t solve this because it’s account-specific and requires manual effort to store and retrieve information.
A third-party option like supermemory.ai fills this gap by acting as a shared, queryable memory layer that sits alongside Claude rather than replacing it. The idea is that when one team member works through a decision in Claude, that context becomes retrievable by another team member later, instead of staying locked inside one person’s chat history. supermemory.ai offers a paid plan around $19 a month, with a free tier available to test first. The tricky part is balancing what should remain private to one person’s machine versus what should be pushed into the shared, team-queryable memory pool, since not every conversation is meant for everyone.
Is this setup worth it for most teams?
For teams already using Notion or a similar permissioned drive, plus a handful of everyday SaaS tools, this setup gets most of the benefit of a purpose-built team AI system without custom engineering. It uses tools teams already pay for and understand, and the Notion and Claude desktop pieces are simple enough for non-technical staff to use daily. The Composio gateway step for scoped, seatless access is the one part that leans technical, and the shared memory layer still requires judgment calls about what counts as shareable context versus personal notes. It’s not a complete team infrastructure solution, but it closes most of the gap that currently exists.
Frequently Asked Questions
Does Claude have any native team memory feature?
No. Claude’s memory is tied to an individual account, so context and history from one person’s conversations aren’t visible to teammates using their own accounts.
Do I have to use Notion for the shared context layer?
Remy is new. The platform isn't.
Remy is the latest expression of years of platform work. Not a hastily wrapped LLM.
No. Notion works well because it already has permissions and multi-user editing built in, but any shared drive or cloud document tool with similar permission controls, like Google Drive, can serve the same purpose.
How does Composio avoid the need to share API keys?
Each team member connects their own account to a given app through Composio using their own login. Composio stores the underlying authentication, and Claude reaches those apps through one connector per person rather than a shared key everyone can see.
What happens when someone leaves the team?
Because each person authenticates individually through Composio rather than using a shared API key, removing their access typically means revoking their seat or login rather than rotating a key used by the whole team.
Is supermemory.ai required, or can teams build this without it?
It’s one option for adding a shared, queryable memory layer on top of Claude. Teams could attempt something similar with manual documentation, but a dedicated memory tool automates capturing and retrieving context that would otherwise sit unused in individual chat histories.
