From the Sanskrit Documents, we can source some of the following works dedicated to Manasā Devī:

• Sarpabhayanāśaka Manasāstotram: सर्पभयनाशक मनसास्तोत्रम्
  (Source yet to identified)

• Manasādevī Stotram: मनसादेवी स्तोत्रम्
  This is found in Brahmavaivarta Purāṇa: Prakṛti Khaṇḍa (Chapter 46: Verse 130). One can read the English translation from here: (Page 468 of the PDF file or Page 407 of the scanned book)

• Manasādevī Dvādaśanāmastotram: मनसादेवी द्वादशनामस्तोत्रम
  (Source yet to be identified)

• Manasā Chālīsā: मनसा चालीसा
  Like all the Chālīsās, this one too is a "modern work", not found in any canonical scriptures.
