● healthy

Give your agent its own email inbox. Create inboxes on demand, send and receive real email, reply on-thread, and pull one-time signup codes and magic links straight out of inbound mail — so an agent can sign itself up for a service or clear 2FA without ever parsing an email body. Real delivery infrastructure behind it: DKIM-signed sending, bounce and complaint handling, suppression lists, and HMAC-signed webhooks. Get a key with no signup form: POST https://api.deadsimple.email/v1/auth/agent-signup

MCP readiness

D · 57/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here D, 37.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	0/10	Handshake needs credentials (HTTP 401); not readable anonymously.
Live MCP endpoint	15/25	Endpoint requires authentication or payment (2415 ms).
Protocol revision	0/10	No protocol revision reported by initialize.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	30/30 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 14 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (2415 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,021 reachable MCP servers in our daily snapshot (2026-11-12 01:39 UTC). Display only; it does not change search order.

Readiness: Higher than 31% of peers; This listing 57 · peer median 81
Latency: Faster than 26% of peers; This listing 544 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Valid MCP handshake −10 — Complete the MCP handshake without errors.
Now: Handshake needs credentials (HTTP 401); not readable anonymously.
Live MCP endpoint −10 — Answer initialize and tools/list at the declared endpoint.
Now: Endpoint requires authentication or payment (2415 ms).
Protocol revision −10 — Support the current protocol revision.
Now: No protocol revision reported by initialize.
