The Agent ExaminerIndependent Review Authority

Best AI agent platforms for research assistants

Research assistants are only as good as the sources they can reach. Native Model Context Protocol (MCP) support lets an agent pull from search, docs, and data connectors without bespoke glue, so tool breadth and memory matter most.

How this ranking is built

Included when the mcpSupport fact is “native”. Ranked by the editorial MCP-nativeness dimension, then the memory dimension.

The editorial score is our opinion, applied by one rubric to every platform including Alfe. See the methodology.
