So I installed MongoDB using brew without any issue. However when I run mongo I get this error

MongoDB shell version: 2.2.3
connecting to: test
Thu Feb 14 18:20:49 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed

Ran mongo in one window and mongod in another but got this error

/usr/local/bin/mongod:3: warning: Insecure world writable dir /usr/local/Cellar in PATH, mode 040777
all output going to: /usr/local/var/log/mongodb/mongo.log

Mongo is actually running completely fine there - you should still be able to run mongo and connect to your local instance.

That warning (note, it's a warning, not an error) says that permissions on /usr/local/Cellar are wrong, you've got it set as 777 which you don't want to do. If you google "insecure world writable dir", there's useful responses there to help you.

Changed the permissions on usr/local/Cellar to go-w and mongo works fine now. Thanks @jackfranklin

sudo chmod -R o-w /usr/local/
