fix(mcp): correct VS Code configuration guide by Kikobeats · Pull Request #56 · microlinkhq/microlink

Kikobeats · 2026-09-13T08:10:33Z

Problem

The README's "VS Code / Codex" section showed the Claude/Cursor mcpServers JSON shape. VS Code does not read that shape: its native MCP configuration lives in .vscode/mcp.json with a top-level servers object, and each stdio server requires "type": "stdio" (per the official VS Code MCP reference). Users following the guide end up with a server VS Code never loads. Codex also does not belong in that claim - it uses its own TOML configuration.

Found during the real-client onboarding audit (VS Code 1.112).

Fix

Section renamed to "VS Code"; the example targets .vscode/mcp.json with servers + "type": "stdio" for the published package, and shows the equivalent server entry for a local checkout.
Codex claim dropped; Cursor section untouched (its mcpServers shape is correct for .cursor/mcp.json).

Tests

New readme-client-config.test.js: the VS Code section must reference .vscode/mcp.json, servers and "type": "stdio" and must not contain mcpServers; the Cursor section must keep mcpServers. MCP suite 105/105 (8 live opt-in tests skipped), lint green.

Note

Low Risk
Documentation and README regression tests only; no runtime or API behavior changes.

Overview
Fixes the VS Code MCP setup docs so they match VS Code’s native .vscode/mcp.json format instead of the Claude/Cursor mcpServers shape that VS Code ignores.

The section is renamed from “VS Code / Codex” to VS Code, documents servers with "type": "stdio" for the published npx flow, and shows a local-checkout server block with the same stdio fields. Cursor (and Claude) examples are unchanged.

Adds readme-client-config.test.js to lock in: the VS Code snippet references .vscode/mcp.json, uses servers and stdio type, and does not mention mcpServers; the Cursor snippet still uses mcpServers.

Summary by CodeRabbit

Documentation
- Updated MCP setup guidance for VS Code, including published-package and local-checkout configurations.
- Clarified the configuration format used by Cursor.
Tests
- Added documentation checks to verify that VS Code and Cursor examples use their correct configuration formats.

VS Code's native .vscode/mcp.json uses a top-level "servers" object and requires "type": "stdio" per server; the README showed Claude/Cursor's mcpServers shape, which VS Code does not read. Keep the Codex claim out (it uses its own TOML config) and preserve the Cursor section. Adds regression tests for both client examples.

📝 Walkthrough

Walkthrough

The MCP README now documents native VS Code servers configurations for published and local setups. A new test validates the VS Code schema and confirms that the Cursor example retains the portable mcpServers schema.

Changes

MCP client configuration

Layer / File(s)	Summary
VS Code configuration examples `packages/mcp/README.md`	The README documents published and local VS Code configurations with `type: "stdio"` and direct server settings.
Configuration documentation tests `packages/mcp/test/readme-client-config.test.js`	New tests validate the VS Code `servers` schema and the Cursor `mcpServers` schema in the README.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 227b1

The documented local VS Code setup is not independently protected by the new test, creating a bounded risk of unnoticed documentation regressions.
