Type Atlas

Type Atlas gives coding agents editor-grade TypeScript, Markdown, and JSON navigation through the Model Context Protocol. It runs locally over stdio and uses the TypeScript project selected for each file, so definitions, references, diagnostics, code actions, and source ranges reflect the repository an agent is actually changing.

Install

Type Atlas requires Node.js 22.20 or newer. No global package installation is required.

Codex

codex mcp add type-atlas -- npx --yes @type-atlas/mcp@latest

Claude Code

claude mcp add --scope user type-atlas -- npx --yes @type-atlas/mcp@latest

VS Code

code --add-mcp '{"name":"type-atlas","command":"npx","args":["--yes","@type-atlas/mcp@latest"]}'

Other MCP clients

{
  "mcpServers": {
    "type-atlas": {
      "command": "npx",
      "args": ["--yes", "@type-atlas/mcp@latest"]
    }
  }
}

Native Windows

Clients that cannot launch the npx.cmd shim directly should invoke it through cmd:

codex mcp add type-atlas -- cmd /c npx --yes @type-atlas/mcp@latest
claude mcp add --scope user type-atlas -- cmd /c npx --yes @type-atlas/mcp@latest

For JSON configuration, use "command": "cmd" and "args": ["/c", "npx", "--yes", "@type-atlas/mcp@latest"].

Restart the MCP server after changing its configuration. Configurations using @latest start the current npm release; pin an exact version when reproducible tool behavior is more important than automatic upgrades.

What agents can do

Type Atlas exposes focused tools for:

  • folded and ranged reads across source, Markdown, and JSON files;
  • document and workspace symbol navigation;
  • definitions, implementations, references, callers, callees, hovers, and signature help;
  • diagnostics, code actions, formatting, imports, symbol renames, and file renames as reviewable patches;
  • package export and dependency-source exploration;
  • bounded workspace structure and behavior-oriented code retrieval.

Token-expanding detail remains opt-in where practical, and tool responses use workspace-relative paths so their locations can be applied directly.
