VFB3-MCP Server

A Model Context Protocol (MCP) server for Virtual Fly Brain (VFB): query Drosophila melanogaster neuroanatomy, connectomics, expression and reagent data from Claude, Copilot or any other MCP client.

Canonical repository: VirtualFlyBrain/VFB3-MCP (this one) โ€” maintained by the Virtual Fly Brain team. Hosted service: https://mcp.virtualflybrain.org โ€” no installation, no API key, no account. (The older address https://vfb3-mcp.virtualflybrain.org is the same server and keeps working.)

The earlier copy at Robbie1977/VFB3-MCP is archived at v1.3.0 and is not maintained; use this repository and the URL above.

This server provides tools to query VFB data, run queries, and search for terms. In HTTP mode it runs statelessly (no session tracking), so any replica can handle any request and standard load balancing works.

๐Ÿš€ Quick Start

The easiest way to use VFB3-MCP is through our hosted service at https://mcp.virtualflybrain.org. This requires no installation or setupโ€ฆ
