Per workspace, off by default
MCP servers are configured per workspace, so a client project does not inherit your internal tooling. Nothing is enabled until you enable it.
What people wire up
Database introspection, issue trackers, internal HTTP APIs, documentation search. Anything with an MCP server becomes available without waiting for us to build an integration.
It composes with local models
Tool calling works with local models that support it — most of the curated coding models do. Check the tool-calling row on any model page.
What it does not do
Tool calling depends on the model. A few local models, mostly the vision and older uncensored ones, have no tool support in their template.
