Overview

What is Milvus?

Milvus is a Model Context Protocol (MCP) server that enables agentic retrieval and semantic search across structured and unstructured data. It is built on top of Milvus, a high-performance vector database optimized for similarity search at scale.

How to use Milvus?

Milvus provides a set of tools accessible through the MCP interface. Users invoke tools by name with their parameters, such as milvus_text_search for full-text search or milvus_vector_search for vector similarity search. No installation or configuration instructions are provided in the README.

Key features of Milvus

Full-text search on collections via milvus_text_search
Vector similarity search with distance metrics (COSINE, L2, IP)
Filter-based querying using expressions like milvus_query
Collection management: list, create, load, release, and inspect
Data insert and delete operations on collections

Use cases of Milvus

Searching documents using full-text queries across a Milvus collection
Finding similar items with vector similarity search (e.g., semantic search)
Filtering and retrieving entities based on structured conditions
Managing collection schemas and loading/unloading for performance

FAQ from Milvus

What tools does Milvus provide?

Milvus provides tools for search and query operations (milvus_text_search, milvus_vector_search, milvus_query), collection management (milvus_list_collections, milvus_create_collection, milvus_load_collection, milvus_release_collection, milvus_get_collection_info), and data operations (milvus_insert_data, milvus_delete_entities).

What are the parameters for `milvus_vector_search`?

milvus_vector_search accepts collection_name, vector (the query vector), vector_field (default: "vector"), limit (default: 5), output_fields, and metric_type (default: "COSINE").

How do I delete entities from a collection?

Use the milvus_delete_entities tool with collection_name and a filter_expr (e.g., 'age > 20') to select which entities to delete.

What is the default result limit for text search?

The default limit for milvus_text_search is 5 results.

Does the server require a running Milvus instance?

The README does not specify runtime dependencies or whether an external Milvus instance must be running; it only states the server is built on top of Milvus.
