A GitHub connection's MCP tool can now point at GitHub's full endpoint
(/mcp/) instead of the read-only one when its owner opts in, at setup
(allow_writes) or later (PUT /api/connections/<id>/writes), which re-reads
the actions and keeps the choices for those on both endpoints. Actions from
the write endpoint are writes unless GitHub marks them read-only, so they
default to asking first.
Admins can forbid it per connector (allow_writes in Admin > Connectors,
kept in app_metadata). Then the option is refused, a refresh goes back to
read-only, and at run time the tool only ever calls the read-only endpoint
and write calls are denied with a reason.
The admin connectors API lists the settings that add Sign in with GitHub
and whether they are complete, next to the required settings (none for
GitHub, which works with tokens alone).
- One control for members' own MCP servers: the custom MCP server row's
switch (it sets both the policy and the instance switch); the separate
top-level switch is gone.
- Connectors that only sync content show "No tools" instead of a
sharing policy, and the policies read "The sharer decides per share",
"Always the sharer's account", "Always each person's own account".
- A connector that needs server settings can't be switched on until they
exist; a tooltip says why.
- On phones the table becomes a list ("On · 2 connections · …") and each
connector's controls open in a sheet.
A connector's enabled switch is now optional: unset means on when the
connector has the server settings it needs, so Google Drive, SharePoint
and Confluence start off until their OAuth settings are present, and an
admin's explicit switch always wins. Changing only the sharing mode no
longer switches a connector on.
Members only see connectors they can use. The catalog, Add Source tiles
and Add Tool leave out anything turned off or still needing setup, except
a connector a member already has a connection to, which stays listed as
turned off so it can be managed or removed.
Six vendor-run MCP servers (Notion, Linear, Atlassian, Sentry, Asana,
Stripe) join the catalog as presets from docsgpt/connectors/presets/
mcp.yaml; existing connections to those servers show under them.
connector_policies lets an admin turn a connector off or force whose
account every share uses, and app_metadata's
connectors.allow_custom_mcp turns custom MCP servers off. Both are
enforced on the server: new connections, OAuth sign-ins, MCP test and
save, and the tools of a disabled connector stop resolving.
GET/PUT /api/admin/connectors reads and changes them.
A shared tool's owner picks owner or member credentials with
PUT /api/connections/tools/<id>/credential-mode, and a member running
the owner's account always confirms write actions.
Tool-call events and retrieved chunks name the connector they came
from (key and display name, never the account), and tool calls keep
those fields when the conversation is reloaded.
