warp-mcp

MCP server for the Ringer WARP platform — SIP trunking, phone numbers, porting, messaging/10DLC, billing, and CDR analytics.

Gives AI agents (Claude, Cursor, Copilot, Codex, ChatGPT) full access to the WARP Customer API: 135 tools covering trunk provisioning, number search and ordering, port-in lifecycle, 10DLC brand/campaign registration, SMS sending, invoices, and call-detail analytics.

Quick Start

# Recommended: global install — the setup wizard runs automatically
npm install -g warp-mcp

# Or run the wizard explicitly / without installing
npx -y warp-mcp setup

The wizard validates your API key, stores it in ~/.warp-mcp/config.json, and registers the server with every MCP client it detects (Claude Code, Claude Desktop, Cursor, Codex, GitHub Copilot, ChatGPT Desktop).

You need a WARP API key (rk_...) — mint one in the WARP portal under Settings → API Keys.

One-command installs

Claude Code

claude mcp add -s user warp -e WARP_API_TOKEN=rk_your_key -- npx -y warp-mcp

Cursor — click to install (then replace YOUR_WARP_API_KEY)

Tools

Prefix	Group	Tools	What it does
trunk_	SIP Trunks	24	Trunk CRUD, SIP credentials, endpoints, IP ACLs, registrations
port_	Porting	33	Port-in requests end to end: draft → validate → submit → activate, documents, TIN compliance
msg_	Messaging	33	Send SMS, message history, 10DLC brands/campaigns, number enrollment, TCR reference data
num_	Numbers	15	Search, order, release DIDs; per-TN voice/SMS config; port-out PINs
team_	Team	9	Members and RBAC roles
bill_	Billing	5	Balance, ledger, invoices (JSON + HTML)
cdr_	Analytics	5	Call detail records, statistics, trends, CSV export
acct_ / net_ / key_	Account	10	Capacity, utilization, scopes, WARP network IPs, API-key audit
warp_status	Diagnostics	1	Config + connectivity check

The server also ships a warp-guide prompt (and server instructions) with deep WARP domain knowledge — workflows, concepts, and common mistakes.

Environment variables

Variable	Default	Purpose
WARP_API_TOKEN	—	API key (rk_...). Overrides ~/.warp-mcp/config.json
WARP_API_BASE_URL	https://api.warp.ringer.tel	API base URL override
WARP_REQUEST_TIMEOUT_MS	30000	Per-request timeout

Token resolution order: env var → ~/.warp-mcp/config.json → unauthenticated (tools return guidance to run setup).

Development

npm ci --ignore-scripts
npm run build   # tsc → dist/
npm test        # vitest (in-memory MCP transport)
npm run dev     # tsx src/index.ts

Releases are published from CI: npm version patch|minor|major, push with --follow-tags, create a GitHub release — the workflow publishes to npm (OIDC trusted publishing with provenance) and to the MCP Registry (io.github.ringer/warp). Do not run npm publish locally after the initial release.
