This is third-party code. Review the repository files before installing.

What it does

The repository does not include its own MCP server; instead it assembles and documents a combination of two other MCP layers for 1C development in Cursor. LN_MCP connects to a live infobase through a web publication and provides query execution, metadata reads and an extension list. MCP_Distr brings up seven Docker containers: metadata and code search, a syntax helper, platform help, templates, a Neo4j dependency graph, and checks including BSP. The project ships a cursor/mcp.json config for eight servers, an agent behavior rulebook USER-RULES.md, an accumulated fixes log memory.md, and a PowerShell script that checks all servers respond.

Who it is for. For 1C developers on Windows with WSL2 who want to bring up both live database access and configuration static analysis for Cursor in one setup.

Example request

Run a query against the live base through LN_MCP, then use MCP_Distr to check where else in the configuration this function is used

Limitations

The setup is not MCP server code itself but configuration and documentation layered on LN_MCP and MCP_Distr from vibecoding1c.ru, so it depends on their availability and versions. It needs Windows 10 or 11 with WSL2, Docker Desktop, and a live infobase web publication. The README's install prerequisites section is brief, with some steps moved into separate docs files.

How to disable. Remove the server entries from cursor/mcp.json and stop the MCP_Distr containers with docker-compose down in the docker/Graph_metadata_search folder.

Transport

http

Authentication

not required

Security check

• LN_MCP runs execute_code and execute_query against the live database
• The MCP_Distr containers open several network ports on the host

README in short

The README draws a two-layer MCP diagram with ports and containers, and lists what the setup includes: a Cursor config, agent rules, a fixes log, env templates, and check and metrics scripts. The install section for a new developer starts with Windows 10 or 11, WSL2 and Docker Desktop prerequisites, with further detail moved into docs/ARCHITECTURE.md and docs/TROUBLESHOOTING.md.
