Verdicts
Context7
Two tools, both annotated readOnlyHint: true and idempotentHint: true. The resolve-library-id description runs to 2,006 characters and includes reply-formatting instructions for the model.
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
Context7
- Call
resolve-library-idfirst unless you already have an id like/vercel/next.js;query-docsanswers a bare name with a not-found message - Ask one concept per
query-docscall and passlanguagewhen you know it; there's no size parameter, so a broad query returns a large chunk - Read the text of every
resolve-library-idresult, because a 429 or 404 there comes back as normal content, not an error - Send
Authorization: Bearer <ctx7sk key>before looping; anonymous limits are low, unpublished and no longer described in the setup docs - Keep secrets and proprietary code out of
query; queries are stored and sent to third-party models for reranking
ModusToolbox AI Assistant
- 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.
- Read
.github/skills/mtb-*and.github/copilot-instructions.mdfor board-specific guidance; they are plain Markdown any agent in the workspace can open. - Run Reset MCP Cache or Generate AI Instructions when the guidance does not match the active board.
- 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.
