ByteAsk Embedded MCP offers a unique and rigorous retrieval approach, focusing on exact facts for embedded development with cited outputs, suitable for high-fidelity agents. However, users should be aware of the distinction between hosted and self-hosted capabilities and the authentication limitations.

ByteAsk Embedded MCP is an open-source MCP server that provides source-grounded, page-cited evidence retrieval for coding agents that write firmware, driver, or protocol code. It returns verbatim snippets with section and page citations, never an authored answer, and says 'no match' when nothing is relevant rather than fabricate. The server supports both stdio and Streamable HTTP transports and exposes a pluggable retrieval backend interface. This repository includes an in-memory SampleBackend for zero-setup demos; the full corpus and retrieval engine are hosted at https://mcp.byteask.ai/mcp.

Tools

search_docs

Search the corpus and return ranked, page-cited evidence.

get_context

Expand a hit to its full source section.

request_document

Ask for a missing document to be added (logged server-side).

Setup

Ensure Python ≥3.10 and uv are installed. 2. Clone the repository and run uv sync. 3. Run uv run byteask-embedded-mcp to start the server in stdio mode. 4. Alternatively, connect directly to the hosted endpoint https://mcp.byteask.ai/mcp (Streamable HTTP).

Fit and risk

Best for

Development scenarios requiring precise, citable embedded documentation facts
Users wanting quick integration and the ability to plug in custom retrieval backends

Not for

Applications needing natural-language summaries or non-verbatim answers
Scenarios where the full corpus is required but self-hosting is insufficient
Users who need authoritative source verification or dedicated support

Required permissions

Accepts queries and returns retrieval results
Can request document additions (logged only)
HTTP server and authentication on local network

Risks and side effects

Full retrieval capability is only available via the hosted service; self-hosted backend is illustrative and may not cover all documents.
The HTTP transport's bearer authentication is a stub; replace with production-grade auth before public deployment.
DNS-rebinding protection exists, but additional hardening is needed when exposing publicly.
Tool outputs come from documents that may be unofficial or outdated; users should verify facts.

Troubleshooting

Ensure Python version meets requirements (≥3.10) and uv is installed.
Run `uv run pytest` to check basic functionality.
Check environment variables like `BYTEASK_BACKEND`, `MCP_TRANSPORT`, `MCP_HTTP_AUTH_TOKEN`.
If using local backend, inspect logs directory (`BYTEASK_LOGS`) to debug issues.

Use cases

Firmware development where exact facts like register offsets, Modbus function codes, SCPI commands are needed.

Coding agents that require verbatim snippets with page citations rather than paraphrased answers.

Experimenting with a zero-config sample backend before deciding on a self-hosted retrieval service.
