Email, webhooks, mocks and 170 tools for AI coding agents, over one MCP connection.
Scored across 66 tools
Most tools target distinct resources and actions, but generic tools such as resource_request, wait_for_event, search_tools, list_tools, and run_tool overlap heavily with dedicated lifecycle and waiting tools. Descriptions help, but an agent can easily choose a generic or duplicate path for webhook, email, mock, file, and approval workflows.
The set is mostly snake_case and readable, but conventions are mixed: action_resource (create_monitor, send_email), resource_action (memory_get, wallet_balance, email_draft), and noun-only or noun-phrase names (resource_request, workspace_status). The pattern is not predictable enough for quick tool selection.
66 tools is far beyond a practical MCP surface, even for a broad testing utility platform. Many lifecycle operations are duplicated through umbrella tools like resource_request and run_tool, so the large count is not clearly earned.
Coverage across email, mocks, webhooks, files, credentials/TOTP, memory, monitors, wallets, and login/approvals is extensive. Some lifecycle operations are only reachable through generic umbrella tools or have minor gaps such as limited explicit monitor update operations.
Accept the last successfully observed DNS answers as a monitor’s new baseline. Use only after reviewing that the change is expected.
Inputs: id (required).
Store a TOTP authenticator for an account your human asked you to create or operate. Requires an approved workspace key. Provide name and one of uri (otpauth://totp), secret (Base32), or imageBase64 (PNG/JPEG QR, at most 1 MiB and one million pixels). Secrets are encrypted and never returned. Free allows 2, Pro 25, Team 100.
Inputs: name (required), uri, digits, period, +3 more.
Ask your human before a risky or irreversible step (deploying, paying, deleting, emailing real people). Emails the workspace owner a link; only they can answer, signed in. Returns an id and answerUrl (show it in chat too), then call wait_for_approval. Needs an approved workspace key.
Inputs: question (required), details, options, timeoutMinutes.
Call a hosted mock route or mutate its CRUD records. Uses the same caller access, limits and revision checks as HTTP. Management tokens do not grant caller access. Owned OAuth providers also accept protocol paths, form fields in body and a userinfo bearer accessToken; authorization redirects include location.
Inputs: id (required), path (required), method (required), body, +2 more.
Complete a test checkout with a fake generated card fixture. Never send real cards. Only the outcome and last four digits are retained. For an extra verification step, repeat with confirmationToken. Use wallet_pay for a test wallet.
Inputs: id (required), card, idempotencyKey, confirmationToken.
Create an owned agent email address. Requires a Free account: one random inbox lasting activeDays (1–7, default 3). Pro allows 10 and Team 50 inboxes that remain active while subscribed; localPart selects a custom address on paid plans. Retired addresses are never reused. Then call wait_for_email.
Inputs: localPart, activeDays.

Inputs: name (required), routes (required), llm, crud, +3 more.
Watch something on a schedule and alert the workspace owner by email (and optionally a webhook) when it goes down or recovers. kind "http" checks a public URL (expectStatus, expectText), "ssl" warns before a certificate expires (sslDays), "heartbeat" returns a pingUrl your job calls when it finishes. kind "dns" watches public DNS records against its first successful baseline (dnsRecordType). Needs an approved workspace key; Free allows 20 monitors every 5 minutes or slower.
Inputs: kind (required), name (required), target, sslDays, +6 more.

Inputs: name (required), users (required), redirectUris (required), claims, +4 more.
Buy a US number using an already-paid phone add-on slot. Operator-enabled Telnyx only. Obtain a number from the phone inventory API first. Keep the idempotencyKey; uncertain purchases must be reconciled, never retried with a new key.
Inputs: number (required), idempotencyKey (required).

Inputs: name (required), balance, persistent, ttlSeconds.
Create a webhook receiver. Senders can POST to the returned webhookUrl without credentials by default. Reading, inspecting and waiting always need workspace credentials or the private inspection token. Set visibility to private only to require senders to supply X-Access-Token. It expires after one hour unless ttlSeconds is set (up to the plan maximum: 1 hour anonymously, 7 days on Free). Save the private inspection token, then use wait_for_webhook.
Inputs: ttlSeconds, visibility.

Create content accepts to, cc, subject, text or html, and optional replyTo (a received message ID). Send accepts approval: true to request human review and optional sendAt (ISO timestamp). Use wait_for_event with the approval ID to wait for a decision. Reviews expire after at most 24 hours or at sendAt or draft expiry if sooner. Only a signed-in owner or admin can resubmit expired or rejected drafts. A decision is separate from delivery status.
Inputs: id (required), action (required), sendAt, content, +1 more.

Inputs: id (required), timeoutSeconds.
Block until the email inbox receives a message, then return new messages with extracted one-time codes and links (verification links first). Pass after (the last message ID seen) to wait for newer ones. Returns timedOut: true after timeoutSeconds (default 25, max 30); call again to keep waiting.
Inputs: id (required), after, token, timeoutSeconds.
Wait once for any of 1–10 webhook, email, human approval, scheduled job or SMS sources. Each source has kind, id, optional token and after cursor. Returns events with per-source cursors, or timedOut. Waits are capped at 30 seconds and share the same per-caller wait limit. Email events exclude sent mail. Expired/denied approval is never permission. Job sources use owned scheduled jobs. SMS sources need an active phone add-on; check /api/capabilities phones before creating a phone number. Existing SMS remains readable during provider outages. This server reports phones=false; scheduled job sources are enabled.
Inputs: sources (required), timeoutSeconds.
Wait up to 30 seconds for inbound SMS. Pass the last message ID as after. A paused or pending number cannot receive messages.
