Best Apache Solr MCP Servers
Apache Solr is an open-source search platform built on Apache Lucene, providing distributed indexing, replication, load-balanced querying, automated failover and recovery, and centralized configuration.
Why this server?
Provides tools for searching and managing Apache Solr indexes via Opensolr's managed service, including hybrid, lexical, and semantic search, RAG-grounded answers, document ingestion and deletion, index creation and inspection, and search tuning.
Why this server?
Provides tools for accessing Apache Solr indexes, enabling full-text and hybrid keyword/vector search, SQL filtering, faceting, sorting, collection discovery, and schema inspection.
AlicenseAqualityBmaintenanceLets AI assistants connect to Apache Solr deployments to enumerate collections and schemas, run full-text and filtered queries, apply faceting and sorting, and issue SQL or vector-semantic searches without building custom API glue. Communicates over stdio or SSE and requires minimal environment configuration instead of app-specific credentials or mandatory ZooKeeper wiring.7MITWhy this server?
Provides access to Apache Solr indexes, allowing hybrid search capabilities that combine keyword search precision with vector search semantic understanding across document collections.
Why this server?
Queries the IATI Datastore's Apache Solr-backed activity and transaction indexes, so agents can search published aid and development activities by country, sector, donor or keyword using Solr query syntax and read back matching documents (commitments, disbursements, dates, counterparties). Responses echo the query that was actually sent so the Solr query can be inspected and refined.
AlicenseNot gradedqualityCmaintenanceEnables searching published international aid and development activities worldwide by country, sector, donor, or keyword, and retrieving full activity records and their underlying commitments and disbursements.58 npmMIT
