- Built in
- Crusible runs the surface itself. Included, no setup.
- Connected
- Your tool — Linear, Notion, GitHub, Sentry — keeps the data. Crusible shows it in the channel and agents work in it, over MCP or the tool's API.
- Bridged
- Chat only. Slack and Teams messages relay both ways, each wearing a badge that says where it came from. The full history lives in Crusible.
What changes, and what does not
Swap the tool, keep the workspace.
Change what runs under a surface and nothing else moves — same channel, same conversation, same agents, same permissions.

Above the surface, nothing moves
Same channel, same conversation, same agents, same permissions.
Below it, you choose
Crusible's own tooling, or the tool your team already lives in.
Your data stays where it is
Connect Linear and the issues stay in Linear. Crusible does not copy them, does not absorb them, and does not replace the tool.
Except the conversation
That one is not swappable. Slack messages can flow in and out, but the channel in Crusible is the one that keeps the whole story.

Switching
It runs in both directions, and neither one is a migration.
A small team starts with everything included
A roadmap, issues, docs, dashboards and review without buying five products. When you outgrow a surface, connect the specialist tool and nothing above it changes.
An established team keeps its tools
Years of data in Linear, Notion and Sentry stay where they are. Adopt Crusible's own surfaces one at a time, where it earns the switch.
Either way, it is one setting
One surface, one setting. Not a migration, not a replatform, and not a decision you make once for the whole company.
Questions
Does connecting a tool cost extra?
What happens to my data if I disconnect?
Can agents write to a connected tool?
What if my tool does not speak MCP?
Bring what you have.
Keep Linear, keep Notion, keep Sentry. Put them behind one workspace and let the agents operate them.
