Overview

## What Virtual Fly Brain does

Virtual Fly Brain is the reference resource for Drosophila neuroanatomy, joining ontology terms, individual neurons, imaging, gene expression and connectome datasets into one addressable structure. The connector reaches it without credentials. Terms and neurons can be searched with the same query engine the website itself runs, entities resolved from informal FlyBase names or split-GAL4 combination names into canonical identifiers, and hierarchies walked in either direction. Synaptic connectivity between neuron classes can be queried across all available connectome datasets at once rather than one dataset at a time, which is the part that would otherwise require stitching sources together by hand.

### Who it is for

Drosophila neuroscientists and students exploring circuits and gene expression.

### Tool surface

Nine tools answered against a published three, and they enforce a workflow rather than sitting flat: get\_term\_info is documented as the discovery step that reveals which pre-computed queries run\_query will accept for a given entity.

Availability

## Where Virtual Fly Brain is listed

Virtual Fly Brain is listed in the Claude connectors directory only. Virtual Fly Brain has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.

Claude listing

## In the Claude connectors directory

Virtual Fly Brain publishes 3 tools to Claude, a deliberately narrow surface; only 11.3% of the 1,253 Claude-listed connectors expose fewer.

The median Claude-listed connector filed under Healthcare & Life Sciences publishes 6, so this one sits 3 tools below its bucket's median, 38th of 51.

It falls in the 1-3 tools band, which holds 16.4% of the Claude directory.

### Measured against the live endpoint

A direct call to the endpoint returned 9 tools, 6 more than the 3 the listing publishes. Probed 2026-08-07.

#### Tools the server actually returns

-   `get_term_info`
-   `run_query`
-   `search_terms`
-   `list_search_facets`
-   `resolve_entity`
-   `resolve_combination`
-   `list_connectome_datasets`
-   `query_connectivity`
-   `get_hierarchy`

Virtual Fly Brain publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.

Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Snapshot

August 2026

Virtual Fly Brain is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.

In the publisher's words
