}MCP Language Server is a Go MCP server that launches an existing stdio language server and exposes semantic code tools to MCP clients. Instead of relying only on text search, Claude can ask for definitions, references, diagnostics, hover information, symbol rename, and structured file edits from the language server that already understands the workspace.
The README includes setup examples for gopls, rust-analyzer, pyright, typescript-language-server, clangd, and other stdio language servers. It is a useful fit for coding-agent workflows where semantic navigation can reduce guesswork and avoid reading broad file ranges just to find symbols.
These sources were reviewed on 2026-06-05. Prefer the live repository, README, license, attribution file, Go module metadata, entrypoint, tool implementation, and Go package documentation for current install and tool behavior.
-- through to the language server.Install the binary with Go:
go install github.com/isaacphi/mcp-language-server@latest
Install the language server for your project, then configure an MCP client:
{
"mcpServers": {
"language-server": {
"command": "mcp-language-server",
"args": ["--workspace", "WORKSPACE_PATH", "--lsp", "gopls"]
}
}
}
For language servers that require additional arguments, pass them after --.
MCP Language Server exposes semantic access to a code workspace. Treat it like connecting an agent to your IDE's language intelligence and refactoring tools. Keep write operations reviewed, especially rename and edit tools that can affect many files.
The server launches the language server you configure. Review the binary, arguments, environment variables, workspace path, caches, and language-specific plugins before use. Tool output can include proprietary source code, file paths, diagnostics, type names, dependencies, and generated edits.

| Safety notes | ✓The server can expose write-capable tools such as symbol rename and structured file edits in addition to read-only navigation tools. It launches the configured language server process with the provided workspace and environment, so review PATH, arguments, environment variables, and workspace scope. Language servers may execute project-specific discovery, indexing, build-script, or plugin behavior depending on the ecosystem and configuration. Keep manual review on rename and edit operations in large workspaces because a language server can change many references across a project. The README describes the project as beta software; expect behavior and compatibility to evolve. | ✓Serena can read and modify files in the project you point it at, including applying symbol-level code edits, so run it on code you can review and version-control. Depending on configuration it can run language servers and execute project commands; only enable it on trusted projects and review its actions. Operate it against a version-controlled working tree so any automated edits can be inspected and reverted through normal diff review. | ✓ChunkHound reads source files, Markdown, text, PDFs, and supported config files under the target directory and stores indexed chunks in a local database. Realtime indexing and daemon mode can continue watching project files after the initial MCP connection. Code research and web search tools require embedding, reranking, and LLM configuration and may invoke local CLIs or external model APIs depending on settings. Exclude generated files, vendored dependencies, secrets, large artifacts, and unrelated repositories before indexing broad workspace roots. Review MCP client configuration carefully when using an absolute project path in a global Claude Desktop config. | ✓Context+ can inspect source files, build AST and embedding indexes, run static analysis, create memory graph nodes, and propose code changes. The `propose_commit` tool is designed to write code after validation and creates shadow restore points before saving. Static analysis tools may invoke local compilers, linters, or language tools depending on the repository. Runtime caches and memory graph data can persist source-derived embeddings and relationships after the MCP session ends. External embedding providers can receive source-derived text, identifiers, prompts, and cluster-labeling context. |
| Privacy notes | ✓Tool results can expose source code, definitions, references, hover text, diagnostics, file paths, module names, package names, build configuration, and generated edits. Language-server logs, MCP client transcripts, model prompts, and debug output can retain proprietary code structure and project metadata. Environment variables passed to the language server may include paths, cache locations, tokens, private registry settings, or build-system credentials. Avoid connecting private workspaces to shared MCP clients or model providers without approval from the project owner. | ✓Project source code, file paths, and symbol information are read into the model context so Serena can reason about and edit the codebase. Avoid pointing it at directories that contain secrets or private data you do not want surfaced to the model. | ✓Indexed chunks, file paths, symbols, comments, Markdown, PDFs, configuration values, database files, daemon state, and search results can reveal proprietary source code and internal architecture. Embedding, reranking, LLM, and web search providers may receive code-derived queries or snippets if configured. Local ChunkHound database files, logs, daemon state, and MCP transcripts may retain code-derived context after the session ends. Avoid sharing ChunkHound databases, config files with API keys, verbose logs, research outputs, and screenshots from private repositories. | ✓Source code, file paths, symbol names, comments, identifiers, embeddings, memory nodes, relations, prompts, API keys, static-analysis output, proposed diffs, and tool results may be visible to the MCP client and model provider. Proprietary codebases can expose internal architecture, feature maps, naming conventions, secrets accidentally present in code, and product plans. Keep API keys and provider base URLs out of committed MCP configs, logs, screenshots, and shared prompts. Review `.mcp_data` and generated restore-point data before sharing workspaces or artifacts. |
