What is Byteask?

ByteAsk Embedded MCP is an open-source MCP server that connects Claude, Cursor, and other AI agents to authoritative embedded systems documentation - datasheets, register maps, and protocol specifications. Instead of generating plausible but unsourced answers, it retrieves exact spec values with page citations from IEEE, Arm, Modbus, CAN, MQTT, and SCPI standards, plus proprietary datasheets you upload. Built for firmware engineers and hardware teams who need agents that cite their sources.

Frequently Asked Questions about Byteask

Do I need an API key or account to use ByteAsk with Claude?

No. ByteAsk requires no signup, key, or token for the public MCP server. Simply add the connector to Claude or any MCP client by pointing it at https://mcp.byteask.ai/mcp.

What standards and documentation does ByteAsk support?

ByteAsk covers IEEE 2030.5, Modbus, CAN/ISO-TP, MQTT, SCPI, Arm Cortex-M datasheets, register maps, and any proprietary datasheets you upload to your private library.

Can I upload my company's proprietary datasheets?

Yes. Organizations can set up a private, org-scoped datasheet library where internal parts, custom components, and NDA-protected designs are visible only to your team's API tokens.

Which AI agents and editors work with ByteAsk?

ByteAsk works with any MCP client, including Claude (UI/App/Code), Cursor, VS Code, Devin, Amazon Q, Cline, Copilot CLI, Gemini CLI, and others.

How does ByteAsk prevent incorrect answers?

Instead of guessing, ByteAsk retrieves exact values from primary source documents and returns them with page citations, ensuring your AI agent answers are verifiable and sourced.
