Implements Issue second-state#34: SeekDB Rust MCP Server with: - rmcp 0.14.0 from crates.io for MCP server - fastembed for client-side embeddings (all-MiniLM-L6-v2, 384 dims) - mysql_async for SeekDB connectivity - Three tools: search_collection, list_collections, collection_info - Local .gitignore for build artifacts
- README.md: concise usage guide, test instructions (--test-threads=1) - config.toml: example EchoKit MCP integration - .env.template: environment variable reference - Cargo.toml: add repository URL, rust-version, updated description - Documents alternative AI_EMBED() for DB-side embeddings
- Add Docker lifecycle commands (start, status, logs, stop) - Document MCP session management with notifications/initialized - Add step-by-step curl examples with actual responses - Clarify EchoKit config.toml location - Explain --test-threads=1 requirement for unit tests - Update all example outputs from live testing
Environment variables are already documented in README.md. The .env.template file is redundant since this implementation uses client-side embeddings without requiring API keys.

Implements a Rust-based Model Context Protocol (MCP) server for SeekDB vector database, located at
examples/mcp/seekdb/. Built withrmcp 0.14.0and features client-side embeddings viafastembed(all-MiniLM-L6-v2model) to reduce the need for api keys and ensure consistency withpyseekdb.MCP Tools Provided:
create_collection: Create tables with 384-dim HNSW vector indexadd_documents: Insert documents with auto-generated embeddingssearch_collection: Perform vector similarity searchlist_collections: List all tables with vector indexescollection_info: Get schema, row count, and embedding infoIncludes usage guide under examples/mcp/seekdb/README.md and unit testing for validation.
Closes #34
