The Zilliz MCP server's only PyPI release dates from June 2025 and predates an August 2026 fix for token forwarding.\n\n## Before you call either\n\n### Meilisearch\n\n1. Create a key with only `search`, `documents.get` and `indexes.get` on the indexes needed. The default search key fails `listIndexes` and `describeIndex` over MCP\n2. Enable the `mcpRoute` experimental feature first. Until then `/mcp` answers `feature_not_enabled`\n3. For hybrid search send `hybrid` with an `embedder` name configured in the index settings and a `semanticRatio` from 0 to 1\n4. Writes return a `taskUid` and run asynchronously. Poll the task before searching for the new documents\n5. On 503 `too_many_search_requests`, wait for the `Retry-After` header (10 seconds) before retrying\n\n### Milvus and Zilliz Cloud API + MCP\n\n1. Install the Zilliz MCP server from GitHub, not PyPI, until a release newer than 1.0.0 ships\n2. Use the cluster endpoint for data (`/v2/vectordb/entities/search`) and api.cloud.zilliz.com only for cluster management\n3. Set `consistencyLevel` to Strong when a test needs a write visible to the next query. The default is Bounded\n4. Expect at most 1,024 results and 10 query vectors per search on Free and Serverless\n5. Return only the fields you need. Returning the vector field multiplies read cost\n\n## Questions\n\n### Which is better for AI agents, Meilisearch or Milvus and Zilliz Cloud API + MCP?\n\nMeilisearch scores 78.6 (A) on agent readiness against Milvus and Zilliz Cloud API + MCP's 57.3 (C), and leads in every scored category.\n\n### Do Meilisearch and Milvus and Zilliz Cloud API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Meilisearch and Milvus and Zilliz Cloud API + MCP without installing anything?\n\nNo hosted endpoint is listed for Meilisearch. Milvus and Zilliz Cloud API + MCP has a hosted endpoint at https://api.cloud.zilliz.com/v2.\n\n### Are Meilisearch and Milvus and Zilliz Cloud API + MCP open source?\n\nYes. Meilisearch is open source (MIT for the Community Edition. Enterprise Edition code, which powers Meilisearch Cloud, is BUSL-1.1).
