01 · Install Filesystem Context

Claude Code

claude mcp add j0hanz-filesystem-context-mcp-server -- npx -y @j0hanz/filesystem-context-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "j0hanz-filesystem-context-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@j0hanz/filesystem-context-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

03 · What Filesystem Context can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can read multiple text files in one request, get metadata for multiple files/directories in one request, and generate a unified diff between two files. Output feeds directly into apply_patch.

Capability map

Tools grouped from the project's README - what Filesystem Context lets an agent do.

read & search

2 tools - e.g. Read multiple text files in one request.; Bulk search-and-replace across files matching a glob. Replaces all occurrences per file. Always dryRun: true first.

read_many · search_and_replace

Stat

1 tool - e.g. Get metadata for multiple files/directories in one request.

stat_many

Calculate

1 tool - e.g. Calculate SHA-256 hash of a file or directory.

calculate_hash

Diff

1 tool - e.g. Generate a unified diff between two files. Output feeds directly into apply_patch.

diff_files

Apply

1 tool - e.g. Apply a unified diff patch to one or more files. Single-file: throws on failure. Multi-file: best-effort per file with results[]. Workflow: diff_files -> apply_
