PromptFax is a pay-per-use remote MCP server that lets an AI assistant send a real fax to a US fax number. Your assistant uploads a PDF or image, enters the destination, reviews a quote, opens Stripe Checkout, and queues the transmission. Pricing is $2.00 for the first 5 pages, then $0.10 per page after that, capped at $4.50 for up to 35 pages. Payment is captured only after the fax is recorded as delivered. There is no PromptFax account, no subscription, and no API key to manage. PromptFax uses OAuth and Streamable HTTP, so users install once and their assistant can start a fax workflow when needed. Inside ChatGPT, PromptFax opens a connector widget that handles document review, destination entry, Stripe Checkout, and the delivery report. Inside Claude or other MCP hosts, PromptFax falls back to an agent-friendly hosted session page that handles the same flow without requiring the host to pass files directly. Every real send requires a user-reviewed quote and Stripe authorization. The assistant cannot silently complete a fax. The `send_fax` and `cancel` tools are marked as destructive so well-behaved MCP hosts can surface confirmation steps. ## Capabilities - Send outbound faxes to US fax numbers - Attach a PDF or image from the host, widget, hosted session page, or HTTPS URL - Generate a pay-per-use quote before payment - Open Stripe Checkout for payment authorization - Queue a paid fax for transmission - Check workflow, payment, and delivery status - Retry eligible failed faxes - Cancel an active send while cancellation is still possible ## Tools - `start_session` — Create or resume a PromptFax MCP session. - `attach_document` — Bind a PromptFax document or HTTPS PDF URLs to an MCP session. - `get_quote` — Create a fax quote from a session, document, or HTTPS PDF URL. - `checkout` — Open Stripe Checkout after the user accepts a quote. - `send_fax` — Queue a paid fax for transmission. - `get_status` — Fetch workflow, payment, and transmission status. - `re

# Coal Coal gives AI agents a real checkout. Discover merchants through the decentralized 0G Storage catalog, pay autonomously in USDC on Base via x402 (Coinbase) or OKX APP (v2 envelope), and download purchased products — all without a human in the loop. Receipts are anchored on 0G Chain, allowing any third party to independently verify payments without trusting Coal itself. The MCP server is fully multi-tenant: every user supplies their own wallet key through the `X-Coal-Agent-Key` header, meaning the server never stores long-lived private keys or custody secrets. Agents are gasless by default — Coal covers operator gas costs. --- ## MCP Tools (13) ### Discovery & Marketplace * `discover_merchants` Browse the marketplace as a Markdown product grid * `search_products` Search and filter by product name, price, or tags * `get_merchant_profile` Retrieve merchant metadata and payout addresses * `query_merchant_memory` Natural-language merchant Q&A powered by TEE-backed 0G Compute --- ### Payments & Checkout * `check_paywall` Check whether an address has already paid * `create_checkout` Create a Coal checkout session *(requires API key)* * `get_checkout_status` Retrieve checkout session state and payment status * `pay_merchant` Send USDC on Base using ERC-3009 gasless transfers --- ### Verification & Delivery * `verify_receipt` Verify the complete proof trail: 1.

# 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 req
