ByteAsk Embedded MCP

What ByteAsk/ByteAsk-Embedded-MCP does

ByteAsk/ByteAsk-Embedded-MCP is designed for the 📟 Embedded System category and supplies source-grounded evidence to coding agents working on firmware, drivers, hardware interfaces, and embedded protocols. Instead of generating an authored explanation, it returns excerpts from indexed reference documents with section and page citations. When the retrieval system cannot find a sufficiently relevant result, it reports “no confident match” rather than filling in an unsupported value.

The corpus described by the project spans grid-interconnection and DER standards, Modbus, CAN, ISO-TP, MQTT, SCPI manuals, MCU datasheets, FPGA and AMD/Xilinx documentation, Ethernet and PCIe IP guides, AMBA AXI, optical-module diagnostics, networking RFCs, IEEE 1588 PTP, exchange protocols, coding guidelines, language standards, and embedded library references.

How it works

The server exposes three MCP tools. search_docs accepts natural-language questions or exact identifiers and returns ranked evidence. Each result includes a document title, section and page citation, a verbatim snippet, and a result_id. get_context uses that identifier to return the complete source section in markdown. request_document records a request for a document that is absent from the corpus; requests are reviewed and are typically added within 24 hours.

The repository separates the MCP server from retrieval and corpus storage. A SearchBackend interface supplies search and context operations, allowing a deployment to connect another retrieval implementation. The repository includes an in-memory sample backend so the local server can run without external credentials, while the hosted endpoint uses the full licensed corpus described by the project.

Setup and configuration

ByteAsk/ByteAsk-Embedded-MCP requires Python 3.10 or newer and uv for the documented local quickstart. Install the project with uv sync, then run uv run byteask-embedded-mcp for a stdio MCP server. The bundled sample backend makes illustrative records available immediately, and the project includes offline tests run with uv run pytest.

The hosted endpoint is https://mcp.byteask.ai/mcp and uses Streamable HTTP. Local settings are controlled through environment variables, including BYTEASK_BACKEND for a custom module:callable backend, MCP_TRANSPORT for stdio or http, HTTP host and port variables, bearer-token configuration, allowed hosts, logging location, and log level. HTTP authentication is described as a shared-secret stub, so public deployments should replace it with a suitable authentication layer. DNS-rebinding protection is configured separately through allowed hosts.

Tools and capabilities

• Search for exact or descriptive references with search_docs.
• Retrieve verbatim, page-cited evidence instead of generated technical claims.
• Expand a result into its full source section with get_context.
• Request a missing standard, manual, datasheet, or library reference with request_document.
• Use stdio for local agents or Streamable HTTP for hosted and networked use.

The tool descriptions are intended to prompt lookups when a query contains details such as hex literals, register names, Modbus function codes, SCPI verbs, MCU part numbers, standards clauses, FPGA document IDs, DMA fields, or coding-rule identifiers.

Limitations and notes

The local repository does not contain the production retrieval engine or the licensed document corpus; those are connected behind the backend interface and power the hosted service. The sample backend therefore provides only illustrative records. A “no confident match” response should be treated as not found, not as permission to infer or guess. The project is marked beta, and the bundled HTTP bearer check is not presented as production authentication.
