Handoff Mcp Server

josephibra/handoff-mcp-server
HTTPregistry active
Summary

Built for orchestrating work across multiple AI agents, this server provides durable handoff primitives and a shared scratchpad over MCP's HTTP transport. It runs on Railway with optional Xpay proxy support and stores state to disk. Discovery endpoints are public by default, but tool execution requires API key auth via Bearer token or x-api-key header. You'd reach for this when coordinating agent chains where context needs to persist across sessions or when one agent's output becomes another's input. The dual-remote setup (Railway + Xpay) gives you flexibility in how clients authenticate and connect.

handoff-mcp-server

Durable handoffs and shared scratchpad for multi-agent workflows over MCP (HTTP transport).

Endpoints

  • GET / basic service info
  • GET /health health and storage stats
  • POST /mcp JSON-RPC MCP endpoint
  • GET /robots.txt discovery file
  • GET /llms.txt discovery file
  • GET /sitemap.xml discovery file

Environment Variables

  • PORT default 3000
  • DATA_DIR default /data
  • MCP_API_KEY required in production (NODE_ENV=production)
  • PUBLIC_MCP_DISCOVERY default true
  • PUBLIC_BASE_URL optional, used for absolute links in discovery files

Local Run

npm ci
npm run build
MCP_API_KEY=test-secret node dist/index.js

MCP Auth Behavior

  • Discovery methods (initialize, tools/list, resources/list, prompts/list, ping) can be public when PUBLIC_MCP_DISCOVERY=true.
  • tools/call requires valid upstream auth when MCP_API_KEY is set:
    • Authorization: Bearer <MCP_API_KEY> or
    • x-api-key: <MCP_API_KEY>

Xpay + Railway Configuration (Required)

  1. Railway variables:
  • MCP_API_KEY=<your-strong-key>
  • PUBLIC_MCP_DISCOVERY=true
  • PUBLIC_BASE_URL=https://handoff-mcp-server-production.up.railway.app
  1. Xpay MCP URL:
  • Use https://handoff-mcp-server-production.mcp.xpay.sh/mcp?key=xpay_sk_...
  • Without ?key=..., Xpay returns auth required and requests will not forward.
  1. Client calls through Xpay:
  • Keep the Xpay key in URL.
  • Also send upstream auth header for tools/call (x-api-key or Bearer token matching MCP_API_KEY).

Publishing

MCP Registry

  • Server name: io.github.josephibra/handoff-mcp-server
  • Primary remote: Xpay URL (with key at client usage time, not committed)
  • Secondary remote: Railway URL

Smithery

  • Namespace: josephibrahim
  • Server ID: handoff-mcp-server
  • MCP Server URL: https://handoff-mcp-server-production.mcp.xpay.sh/mcp?key=xpay_sk_...

Agentverse

  • Create a new agent and attach MCP server:
    • URL: https://handoff-mcp-server-production.mcp.xpay.sh/mcp?key=xpay_sk_...
    • Headers: x-api-key: <MCP_API_KEY> for tool execution paths

Recommended Extra Discovery Listings

  • PulseMCP directory
  • mcp.so
  • OpenTools catalog
  • MCPmarket / mcpservers.org

Use the same canonical MCP URL and matching auth notes everywhere to avoid inconsistent behavior.

# ByteAsk Embedded Docs MCP Page-cited retrieval over embedded systems documentation, datasheets, reference manuals, RTOS documentation, coding standards, and firmware engineering references for AI coding agents. **Registry Namespace:** `ai.byteask/embedded-docs` **Endpoint:** `https://mcp.byteask.ai/mcp` **Documentation:** https://docs.byteask.ai/embedded **GitHub:** https://github.com/ByteAsk/ByteAsk-Embedded-MCP --- # Why This MCP Exists Modern AI coding agents are excellent at generating code, but often struggle when working with vendor-specific embedded documentation, hardware reference manuals, firmware SDKs, and coding standards. Embedded engineers routinely need answers from: * STM32 Reference Manuals * ARM Cortex-M Technical Reference Manuals * CMSIS Documentation * FreeRTOS Documentation * Zephyr Documentation * ESP-IDF Documentation * Nordic SDK Documentation * NXP Documentation * MISRA C * MISRA C++ * AUTOSAR * Device Datasheets * Vendor Application Notes Searching these sources manually can require navigating hundreds or thousands of pages of documentation. ByteAsk Embedded Docs MCP gives AI coding agents direct access to these references and returns page-cited answers grounded in source documentation. --- # Features ## Page-Cited Retrieval Every answer is grounded in source documentation with citations to the original reference. This enables engineers to verify claims directly against vendor documentation. --- ## Documentation Search Search across embedded and firmware engineering references. Examples: * Peripheral configuration * Register descriptions * DMA setup * Interrupt handling * Clock configuration * RTOS APIs * MISRA compliance questions * ARM architecture details --- ## Agent-Native Works directly with MCP-compatible tools including: * Claude Code * Claude Desktop * Cursor * Windsurf * VS Code MCP Clients * GitHub Copilot MCP * Any MCP-compatible agent --- ## Remote Hosted No indexing, crawling, or local setup required. The server is hosted by ByteAsk and continuously updated. --- # Example Prompts ## STM32 ```text Find the STM32H7 Ethernet DMA initialization sequence. ``` ```text Show the documentation for STM32 timer input capture. ``` ```text Find the register definition for RCC clock configuration. ``` --- ## ARM Cortex-M ```text Explain NVIC interrupt priority configuration on Cortex-M4. ``` ```text Find documentation for SysTick configuration. ``` ```text Show Cortex-M exception handling behavior. ``` --- ## CMSIS ```text Find the CMSIS documentation for NVIC_SetPriority. ``` ```text Show CMSIS APIs related to interrupt control. ``` --- ## FreeRTOS ```text Find documentation for task notifications. ``` ```text Compare queues and task notifications in FreeRTOS. ``` ```text Show examples of FreeRTOS software timers. ``` --- ## MISRA ```text Find MISRA C rules related to pointer arithmetic. ``` ```text Show MISRA C++ guidance on exception handling. ``` ```text Find rules regarding dynamic memory allocation. ``` --- ## Zephyr ```text Find Zephyr GPIO driver documentation. ``` ```text Show examples of Zephyr work queues. ``` ```text Explain Zephyr device tree configuration. ``` --- # Supported Knowledge Domains ## Embedded Systems * Microcontrollers * SoCs * Device Drivers * Peripherals * DMA * Interrupts * Timers * GPIO * UART * SPI * I2C * CAN * Ethernet * USB ## Firmware Engineering * RTOS Development * Bare-Metal Development * Bootloaders * Hardware Abstraction Layers * Embedded Networking * Memory Management ## Documentation Sources * Reference Manuals * Datasheets * SDK Documentation * Application Notes * Programming Manuals * Technical Reference Manuals * Architecture Specifications ## Coding Standards * MISRA C * MISRA C++ * AUTOSAR * Embedded Best Practices --- # Installation Use the MCP endpoint: ```text https://mcp.byteask.ai/mcp ``` Refer to the documentation for client-specific installation instructions: https://docs.byteask.ai/embedded --- # Example Workflow Engineer asks: ```text How do I configure Ethernet DMA on STM32H7? ``` Agent: 1. Queries ByteAsk Embedded Docs MCP 2. Retrieves relevant documentation sections 3. Produces a grounded answer 4. Includes citations to the source material Result: * Faster debugging * Fewer hallucinations * Traceable answers * Direct access to source references --- # Ideal Users * Embedded Software Engineers * Firmware Engineers * RTOS Developers * Automotive Software Engineers * Safety-Critical Software Teams * Embedded AI Engineers * Hardware Bring-Up Teams * BSP Developers * Driver Developers * Platform Engineers --- # About ByteAsk ByteAsk builds citation-backed retrieval systems for high-value technical knowledge. The Embedded Docs MCP provides page-cited access to embedded and firmware engineering documentation directly inside AI coding workflows.
