## Architectural Patterns
### Direct connection to the database
Configuration extension + HTTP service in 1C, MCP server connects directly.
**When:** need access to live data and metadata, control over the database.
**Servers:** `mcp-1c`, `1c_mcp`, `1c-mcp-toolkit`
### Working with configuration dump
Parsing XML/EDT dump without connecting to a running database.
**When:** CI/CD, code review, analysis without access to 1C server.
**Servers:** `1c-mcp-metacode`, `bsl-graph`, `mcp-1c` (dump mode)
### RAG / semantic search
Indexing metadata and documentation in vector/graph database.
**When:** need natural language search, large configurations (ERP, BSP).
**Servers:** `mcp-1c-v1` (Qdrant), `1c-mcp-metacode` (Neo4j), `onec-help-mcp`
### Bridge to existing tools
MCP wrapper over LSP, REST API, or other protocol.
**When:** existing infrastructure (BSL LS, OData, 1C: Companion), need MCP access.
**Servers:** `mcp-bsl-lsp-bridge`, `1c-rest-mcp`, `1c-buddy`, `spring-mcp-1c-copilot`
