"Merchant Category Code (MCC) data lookup" matching MCP servers:

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

MCP server that connects Claude Code to Slack, allowing two-way communication via Slack Socket Mode without tunnels.

Lets you @mention a bot in a Slack channel or DM to send work to a local Claude Code session and watch it run, with live self-updating turn cards, threaded answers, progress checklists and a per-channel inbox with read cursors. It runs entirely on your machine over Slack Socket Mode—no tunnel or public IP—routes misdelivered messages to the right project, and masks credentials in anything it posts back.

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.

Read-only MCP server for Twilio call data, providing tools to search calls, fetch recordings and transcripts, list agents, and generate summaries while explicitly handling timezone and duration measurement discrepancies.

Enables sending properly rendered Markdown messages to Telegram and remotely resetting Claude Code's context, addressing gaps in Anthropic's official Telegram channel.

Enables AI coding assistants to send real-time status updates through a bot, covering task start, milestones, warnings, blockers, and completion.

Enables agents to explore the Slack SDK's allowed methods via TypeScript signatures and then run JavaScript that chains multiple Slack Web API calls in a single sandboxed execution. The isolate holds no network access or Slack token, since credentialed calls are brokered by the host.
