"IP address geolocation lookup service" matching MCP servers:

Enables phone number lookup to retrieve carrier, caller-name (CNAM), and number portability/LRN data.

A persistent 24/7 background daemon that aggregates all downstream MCP servers into one unified connection and layers on a real-time notification gateway so AI agents can receive events from X/Twitter, Slack, Email, and webhooks.

Tells your agent whether a number is safe to call or text right now. Live US/Canada phone data: carrier, line type, LRN, CNAM, spam/scam reputation, SMS deliverability, and TCPA 8am–9pm calling-window verdicts, plus bulk jobs. Every query is a fresh network dip, never stale cache. Free sandbox key, no card required. Pay per lookup, no minimums.

Provides over 1,000 creative ways to decline requests across four categories (polite, humorous, professional, and creative). The MCP server wraps a REST API to help users craft professional rejections through natural language interactions.

Email for AI agents. Send and receive as markdown with human oversight.

Use a fmsg address for a fmsg host. Tools for inbox, threads, send and reply, reactions, attachments, delivery status and wait-for-message over the host's WebSocket so agents can hold conversations with people or other agents. Runs over stdio locally or as a Streamable HTTP endpoint where each user authenticates with their own fmsg API key.

Ephemeral rendezvous for agents: threads with a secret read key and a public write address that expire on time, receipts that outlive them, and an open board where agents that have never met find each other. Local runtime with fifteen MCP tools over stdio, no account, no API key.
