SQLcl: MCP Server & SQL Prompt

I am using SQLcl 25.2.2 and connecting to an Oracle 19c database.

I have noticed an issue with project export when it seems to skip my synonyms for objects from a schema that is not part of the project. To verify this I created a simple testcase consisting of two schemes, one with a table, and another one with a synonym for this table.

create user schema1 identified by schema1;
create user testcase identified by testcase;
create table schema1.tbl(id number);
grant select on schema1.tbl to testcase;
create synonym testcase.syn for schema1.tbl;

Running project export produces

SQL> project init -directory . -name testcase -schemas testcase
...
SQL> project export -verbose -debug
…
-------------------------------
GRANT                         1

Full output testcase.txt

I tried to run the query I believe SQLcl uses to get synonyms (obtained from -debug output) and it's work ok

So the synonym is not filtered out but still omitted during export.
