Side-by-Side Model Context Protocol Comparison
MCP Server vs Jmap MCP
In-depth architectural comparison of the MCP Server and Jmap MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
MCP Server
Communication · Local stdio
Quality: 64/100 (Good) | Auth: API Key required
Jmap MCP
Communication · Remote HTTP/SSE
Quality: 61/100 (Good) | Auth: API Key required
Verdict Summary: Choose MCP Server if you need specialized Communication tools running via a local process. Choose Jmap MCP if your workspace requires Communication integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose MCP Server when:
You need dedicated capabilities in the Communication domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: VIRTUALSMS_API_KEY.
Receive SMS verification codes with AI agents. Get virtual phone numbers for WhatsApp, Telegram, Google, and 500+ services. Own modem infrastructure across 200+ countries with real-time WebSocket delivery. 12 tools for number discovery, purchase, and code extraction.
A Model Context Protocol (MCP) server that provides tools for interacting with JMAP (JSON Meta Application Protocol) email servers. Built with Deno and using the jmap-jam client library.

Tools & Capabilities Breakdown
MCP Server Tools (40)
virtualsms_list_proxy_catalog
List available proxy pool types, countries, and price-per-GB. Use this before buying proxy traffic.
virtualsms_list_proxies
List all proxies on your account with remaining GB and login credentials. Returns proxy_id values for use with get_proxy_usage, rotate_proxy, set_proxy_targeting, and generate_proxy_endpoint.
virtualsms_buy_proxy
Purchase proxy traffic (GB) for a selected pool type. Returns proxy credentials and remaining balance. country_code here is only a soft preference for provisioning. For actual per-connection targeting (country/state/city/zip/asn) or a ready-to-use connection string, use virtualsms_generate_proxy_endpoint after buying. To persist a default targeting on the sub-user, use virtualsms_set_proxy_targeting.
virtualsms_rotate_proxy
Request a fresh IP for an existing proxy. Useful when an endpoint flags the current exit IP.
virtualsms_get_proxy_usage
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
MCP Server is categorized under Communication and uses a local stdio subprocess. In contrast, Jmap MCP belongs to Communication using remote streaming HTTP/SSE transport. Select MCP Server when you need capabilities focused on communication and Jmap MCP when you require tools for communication.
Get cached GB used/remaining and request count for one proxy. Cheap, no upstream call. Reads a cached value refreshed every ~5 minutes.
virtualsms_get_proxy_usage_history
Get a per-day traffic (GB) and request-count series for one proxy over the last 7 or 30 days.
virtualsms_set_proxy_targeting
Persist a default geo-targeting (country, and optionally cities/ASNs) on an existing proxy sub-user. Country-only is free. Adding cities or ASNs bills the GB on your OWN allocation at 2x (not on residential_premium, where refined targeting is included free). This changes the STORED default. For a one-off connection string with any targeting (including state/zip), use virtualsms_generate_proxy_endpoint instead.
virtualsms_test_proxy
Make one request through a proxy and report the exit IP, country, city, ISP, and latency. Proves the proxy works and which country it exits from. Consumes a small amount of the proxy's GB allocation. Rate-limited to about once per 20 seconds per proxy.
virtualsms_list_proxy_locations
List available cities, states, ASNs, or ZIP codes for a pool type + country. Use this to discover valid location_code values before calling virtualsms_generate_proxy_endpoint or virtualsms_set_proxy_targeting with sub-country targeting. Public endpoint, no purchase required. Not available for residential_premium (only residential, mobile, datacenter).
virtualsms_generate_proxy_endpoint
Build ready-to-use proxy connection string(s) for an owned proxy: country/state/city/zip/asn targeting, rotating or sticky session, HTTP or SOCKS5, in host:port:user:pass / user:pass@host:port / curl format. Nothing is purchased or changed server-side. This only composes a connection string from the proxy's existing credentials (same convention as the VirtualSMS dashboard's endpoint generator). Sub-country targeting (state/city/zip/asn) bills the proxy's own GB at 2x on non-premium pools, free on residential_premium.
virtualsms_start_manual_registration_session
Beta, invite-only. Start a country-matched cloud browser you drive yourself: returns a viewer_url, an authenticated live-viewer link you open to watch and drive the session (manual takeover), plus optional order phone number and timeline. Agent-driven navigation is the separate opt-in session tools. Pair with create_order for OTP + browser in one agent flow.
virtualsms_list_services
Get all available SMS verification services (Telegram, WhatsApp, Google, etc.). Use this to discover valid service codes before buying a number.
