Couldn't reach the MCP server
Almost always a typo in the URL. It is
/mcp/crm or /mcp/studio, not
/crm and not /mcp.Check the server is up first:200 means Sailer is fine and the problem is your URL or client config.No Sailer account for this sign-in

The email you used at Auth0 is not a member of any Sailer workspace. Sign
in with the address your Sailer account uses, or ask an admin to invite
you.
No workspace available
No workspace available
Your account exists but belongs to no workspace. An admin has to add you
to one.
Consent shows fewer permissions than I expected

It is showing what your role in that workspace can grant. Anything
struck through is a scope your role cannot give away, so it will not be
included. Ask an admin to widen the role if you need it.First connection is reads only on purpose. Writes are a
reconnect, not a missing checkbox you overlooked.

A connection is bound to one workspace for its lifetime. The binding lives
inside the token, which is why no URL names a company.Remove the connector and add it again, then pick the other workspace — or
approve the write scopes — at consent. Same reconnection for both.You cannot point one URL at two workspaces at once.
CRM token on Studio, or the other way around

OAuth tokens are minted for exactly one server. Using a CRM grant on
Studio is 401, not 403. Audience mismatch is not a missing scope.
Reconnect to the other URL. Retrying will loop.
The connector has no Sailer logo
The connector has no Sailer logo
Expected for a custom connector. Claude and ChatGPT only render a logo
for directory listings, where the icon is uploaded separately. The server

Unknown field, not found, missing scope
Unknown field, not found, missing scope
MCP errors are written for the model, which is about to decide what to do
next.
- Unknown field — name the key and often a suggestion. Call
describe_schema. Do not retry the same key. - Not found — deleted, other workspace, or outside your ACL. Same next step: list or search again. Do not retry the id.
- Missing scope — the message names the scopes and says retrying will not help. It won’t. Reconnect and grant them.
