## Verdicts

**Microsoft Learn MCP Server.** Access requires no account, key or card. No status page was found, and the FAQ does not specify numeric rate limits.

**ModusToolbox AI Assistant.** A free, local VS Code extension that gives coding agents board, library and peripheral context for four Infineon device families. Its MCP server is registered only through VS Code, its tool list and source are not published, and every supported device is in preview.

## Before you call either

### Microsoft Learn MCP Server

1. Append `?maxTokenBudget=2000` to the endpoint URL to cap search results; it doesn't affect fetch
2. Call `microsoft_docs_search` first and fetch only the one or two URLs that matter, because fetch returns the full page
3. Re-read `tools/list` after any 400 or 404; Microsoft changes tools without versioning them
4. Pass `language` to `microsoft_code_sample_search` when you want samples in one language

### ModusToolbox AI Assistant

1. Expect this only inside VS Code, with ModusToolbox 3.7 or later, Python 3.9 or later and the ModusToolbox for VS Code extension installed.
2. Read `.github/skills/mtb-*` and `.github/copilot-instructions.md` for board-specific guidance; they are plain Markdown any agent in the workspace can open.
3. Run Reset MCP Cache or Generate AI Instructions when the guidance does not match the active board.
4. Check the board is PSOC Edge E84, PSOC Control C3, PSOC 4 HV or TRAVEO T2G before relying on it; PSOC 6 and PSOC 4 are not supported yet.
