faker-mcp

Hosted endpoint:https://free.cadenya.com/faker-mcp

The footprint of tools is very low (not every faker category is loaded into context, that would be a waste of input tokens).

The service builds its catalog from the exported faker-go API at startup. It includes every reflected method that can be called with JSON-friendly scalar arguments and returned as text or JSON. Example faker names:person.name,internet.email,company.name,address.city,lorem.sentence,faker.int_between,uuid.v4,color.hex.
