BSL Language Server installer
A script installs BSL Language Server as a Linux systemd service and, with a flag, opens an MCP endpoint for AI agents
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- Opens a network port with no built-in authentication
- Tools read 1C configuration files on the server
Install
Manual install
bash <(curl -fsSL https://raw.githubusercontent.com/vitebc/bsl-server-installer/master/install.sh) --mcpInstalls the service in one command with the MCP endpoint on port 8025.
This is third-party code. Review the repository files before installing.
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

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.

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.
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.
