What it does
A bash script installs BSL Language Server (a code analyzer for 1C's BSL language) on Ubuntu or Debian: it checks Java 17, creates a system user, downloads the latest release, places the JAR under /opt, and generates a config and a systemd service. The server runs in LSP mode over WebSocket for diagnostics and formatting. With the --mcp flag it also opens a Streamable HTTP MCP endpoint with ten tools: file analysis, module symbol tree, reference search, call hierarchy, definition, and type info. Port, bind address and install path are set with command-line flags.
Who it is for. For 1C developers and devops engineers who run a BSL code analysis server on a separate machine and want AI agents to reach it.
Good fit when
- You need a shared BSL static analysis server for a team or CI
- An agent needs to look up definitions, references and call hierarchy in 1C code without opening the whole configuration
- You need LSP over WebSocket for an IDE and MCP for an agent on the same server
Not a fit when
- You need analysis right on your own machine without a Linux server and systemd
- You need built-in authentication: the server has none, and public access needs a reverse proxy

Limitations
Installs only on Ubuntu 20.04+ or Debian 11+ with Java 17 and needs sudo. BSL Language Server itself has no authentication; for outside access the README recommends nginx with TLS or an SSH tunnel. The MCP endpoint works over source code, not a live database, so the configuration code must be on the server's disk.
How to disable. Stop and disable the service with sudo systemctl stop bsl-language-server and sudo systemctl disable bsl-language-server, then remove /opt/bsl-language-server and the server entry from your MCP client config.
FAQ
Can I install just LSP without MCP?
Yes, the --mcp flag is optional; without it the script installs only the WebSocket LSP server on port 8025.
How do I restrict outside access to the MCP endpoint?
The README suggests a TLS reverse proxy in front of port 8025 or an SSH tunnel, since the server has no built-in authentication.

README in short
The README covers installing BSL Language Server as a systemd service, an LSP/MCP endpoint table, command-line parameters, a list of ten MCP tools, and a security section with nginx and SSH tunnel examples. The analyzer itself is Apache 2.0, the install scripts are MIT.
