## Tools
- get_term_info - Get term information from VirtualFlyBrain using one or more VFB IDs. Supports batch requests — pass an array of IDs to fetch multiple terms in parallel. When multiple IDs are provided, results are returned as a JSON object keyed by ID. The Images field is keyed by template brain ID — use these to construct VFB browser URLs: https://v2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=<VFB_ID>&i=<TEMPLATE_ID>,<IMAGE_ID1>,<IMAGE_ID2> where id= is the focus term and i= is a comma-separated list of image IDs for the 3D viewer (template ID must be first in the i= list to set the coordinate space). Endpoint: https://vfb3-mcp.virtualflybrain.org
- run_query - Run a query on VirtualFlyBrain using a VFB ID and query type. Supports batch requests — pass an array of IDs to run the same query_type on all of them, or use the queries array for mixed ID/query_type combinations. When multiple queries are provided, results are returned as a JSON object keyed by "ID::query_type". IMPORTANT: Do NOT pass tool names (like "get_term_info" or "search_terms") as query_type — those are separate tools. Valid query_types are returned by get_term_info in the Queries array for each entity. Common query_types include: PaintedDomains, AllAlignedImages, AlignedDatasets, AllDatasets (for templates); SimilarMorphologyTo, NeuronInputsTo, NeuronNeuronConnectivityQuery (for neurons); ListAllAvailableImages, SubclassesOf, PartsOf, NeuronsPartHere, NeuronsSynaptic, ExpressionOverlapsHere (for classes). Available query_types vary by entity type — ALWAYS call get_term_info FIRST to see which queries are available for a given ID, as attempting invalid query types will result in an error message directing you to use get_term_info. Endpoint: https://vfb3-mcp.virtualflybrain.org
- search_terms - Search for VFB terms using the Solr search server. Results can be filtered, excluded, or boosted by entity type using facets_annotation values.

Available filter types: entity, anatomy, nervous_system, individual, has_image, adult, cell, neuron, vfb, has_neuron_connectivity, nblast, visual_system, cholinergic, class, secondary_neuron, expression_pattern, gabaergic, expression_pattern_fragment, glutamatergic, feature, sensory_neuron, neuronbridge, deprecated, larva, has_region_connectivity, nblastexp, gene, primary_neuron, flycircuit, mechanosensory_system, histaminergic, lineage_mbp, peptidergic, hasscrnaseq, chemosensory_system, split, has_subclass, olfactory_system, dopaminergic, fafb, l1em, pub, enzyme, motor_neuron, cluster, lineage_6, lineage_3, serotonergic, lineage_19, lineage_cm3, lineage_dm6, proprioceptive_system, gustatory_system, sense_organ, lineage_mbp4, lineage_mbp1, lineage_1, lineage_mbp2, lineage_all1, lineage_balc, lineage_cm4, lineage_dm4, muscle, lineage_13, lineage_8, lineage_mbp3, lineage_12, lineage_dm1, lineage_dpmm1, lineage_9, lineage_cp2, lineage_dl1, fanc, lineage_7, lineage_vpnd2, lineage_dm3, lineage_dpmpm2, lineage_14, lineage_4, lineage_blp1, lineage_dalv2, lineage_eba1, lineage_dm2, lineage_dpmpm1, auditory_system, lineage_16, lineage_blvp1, lineage_blav2, lineage_vlpl2, lineage_alad1, lineage_bamv3, lineage_bld6, lineage_vpnd1, synaptic_neuropil, lineage_23, lineage_17, lineage_10, lineage_dplpv, lineage_21, lineage_alv1

Multiple filter_types are ANDed (results must match ALL). Multiple exclude_types are ORed (any match excludes). boost_types soft-rank matching results higher without excluding others. Endpoint: https://vfb3-mcp.virtualflybrain.org
