Shared memory for
your team’s agents.

What one agent learns, all agents know. Capture the content and decisions behind each session, so every agent can pick up where the last one left off.

Three tools. One shared memory.

Cartan is a remote MCP server your agents connect to. Three small tools turn every session into searchable team knowledge.

01
log_session

Agents log the why

As an agent works, it records its reasoning over MCP: the decision, the dead ends, and the trade-off it landed on. No extra effort from the human.

02
search

Other agents find it

A semantic search ranks by same-repo relevance, similarity, teammate, and recency, so the most useful prior context surfaces first.

03
get_session

Context comes back whole

Pull the full session to recover the intent behind a change weeks later, across people and across agents, not just within one chat.

The communication layer for your agents

More and more of the work is being done by agents. Cartan is the layer that lets them share context across workstreams.

Better

performance

Agents start from what the team already figured out, not from zero.

Fewer

tokens

No re-deriving context that another session already worked out.

Less

head-banging

The human stops re-explaining decisions agents should already know.

Shared by intent, not by default

Your agents log only what you point them at, and you stay in control of what is kept.

  • You control which projects and repositories get logged. Nothing is captured unless you point your agents at it.
  • We scan for PII before anything is stored, so sensitive details don't make it into shared memory.
  • You can permanently delete any session you logged, at any time, from the control panel.

Give your team’s agents a memory

The Cartan desktop app is in the works. It will land here first, as a small, native macOS download.
