MCP server for beacio — unified tools for SDK consumers and extension developers shipping iOS Safari Web Bluetooth.
This MCP server presents well-structured tool definitions with consistent naming patterns (verb_noun format), comprehensive parameter descriptions, and proper enum constraints. All 12 tools have descriptions and input schemas visible. However, output schemas are not documented in the source code provided, and error handling guidance is minimal. The server demonstrates solid fundamentals aligned with production tool patterns, but lacks the refinement expected of A-grade tooling (e.g., no explicit pagination, no documented return types, no recovery hints in error scenarios).
Get best practices for Web Bluetooth development with Beacio, optionally filtered by topic.
Check if the current environment supports iOS Safari Bluetooth via Beacio (no parameters required).
Show a complete working code example for a specific BLE profile (heart_rate, battery_service, device_information, nordic_uart, hm10_serial).
Search for relevant source files and code examples matching a query string.
Generate a step-by-step installation guide for integrating Beacio into a web project based on framework and package manager.
List the directory structure of a project, respecting .gitignore patterns and traversal depth limits.
Patch an existing Web Bluetooth application's HTML and JavaScript to support iOS Safari via Beacio.
Output schemas not documented. None of the 12 tools have visible return type documentation in the source provided. LLMs cannot infer what fields to expect, forcing them to guess about downstream composition and inviting context loss.
Error handling lacks recovery guidance. Tool descriptions mention functionality but do not specify how errors should be handled or what an LLM should do if a call fails. E.g., patch_existing_app does not indicate what happens on malformed HTML/JS input.

Get detailed guidance on advanced/premium Beacio APIs and features.
Search the Beacio documentation for topics matching a query string.
Get the Web Bluetooth API specification citation and documentation for a specific method.
Get troubleshooting advice for common Beacio integration issues.
Verify that a Beacio integration is correct for a given framework and deployment mode (greenfield scaffolded app or brownfield existing app).
Tool descriptions are moderately brief (avg ~70-100 chars). While not critically short, they could be richer with WHEN/WHY context. E.g., 'spec_citation' description 'Get the Web Bluetooth API specification citation and documentation for a specific method' (97 chars) lacks guidance on when to prefer this over search_docs or best_practices.
No pagination or result-limiting documented. Tools like search_docs and find_examples accept a query string but do not specify max results, pagination parameters, or result count limits. Large result sets could overflow context.
Tool composition not optimized for common workflows. E.g., an LLM wanting to 'integrate Beacio for React with npm' must call install_plan, then verify_integration separately. No composite tool wraps both steps, forcing multi-turn reasoning.
