1. Update to v0.7.0:

npm update @mizchi/lsmcp

2. Update your tool references to use the new names (remove`lsmcp_` prefix)

3. If you're using typescript-language-server, "Go to Definition" should now work correctly without any additional configuration

</details>

For advanced users who want more control over LSP server configuration, you can set up lsmcp manually with custom settings.

{

"mcpServers": {

"rust-minimal": {

"command":"npx",

"args": [

"-y",

"@mizchi/lsmcp",

"--bin",

],

"env": {

"RUST_ANALYZER_CONFIG":"{\"assist\":{\"importGranularity\":\"module\"},\"cargo\":{\"allFeatures\":true}}"

}

}

}

}

You can configure any LSP server by providing the binary path and optional initialization options:

{

"mcpServers": {

"custom-lsp": {

"command":"npx",

"args": [

"-y",

"@mizchi/lsmcp",

"--bin",

"/path/to/your/lsp-server",

"--initializationOptions",

]

}

}

}

For complex LSP server configurations, you can use the`--config` option to load settings from a JSON file:

1. Create a configuration file (e.g.,`my-language.json`):

{

"id":"my-language",

"name":"My Custom Language",

"bin":"my-language-server",

"args": ["--stdio"],

"initializationOptions": {

"formatOnSave":true,

"lintingEnabled":true,

"customFeatures": {

"autoImport":true

}

}

}

2. Use it with lsmcp:

claude mcp add my-language npx -- -y @mizchi/lsmcp --config ./my-language.json

{

"mcpServers": {

"my-language": {

"command":"npx",

"args": ["-y","@mizchi/lsmcp","--config","./my-language.json"]

}

}

}

This approach is useful when:

- You have complex initialization options

- You want to share configurations across projects

- You need to version control your LSP settings

Some LSP servers can be configured via environment variables:

{

"mcpServers": {

"configured-lsp": {

"command":"npx",

"args": ["-y","@mizchi/lsmcp","--bin","lsp-server"],

"env": {

"LSP_LOG_LEVEL":"debug",

"LSP_WORKSPACE":"/path/to/workspace"

}

}

}

}

npx @mizchi/lsmcp --language<language> --bin'...'

npx @mizchi/lsmcp -p<preset> --bin'...'

npx @mizchi/lsmcp --preset<preset> --bin'...'

npx @mizchi/lsmcp --bin'<lsp-command>'
