Available components
Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
Recent critical change
TLS certificate (10 Sept 2026). See the changelog before you install this server.
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security0
- TLS check failed: the certificate doesn't match the endpoint's hostname. See how to fix → View diagnostics → Fail
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS not yet verified: we couldn't read the response headers to check for it. View diagnostics → Unverified
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the TLS certificate failed verification. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools.Unverified
Capabilities0
- Capabilities not yet verified: we couldn't read the endpoint's capabilities.Unverified
Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the AgenticEmail MCP server?
AgenticEmail is a hosted endpoint at https://api.agenticemail.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the AgenticEmail MCP server?
AgenticEmail is an MCP server listed in the public MCP registry as dev.agenticemail/mcp. Hosted email for AI agents: create inboxes, send, receive, and reply over MCP with scoped API keys. This page covers its hosted endpoint (https://api.agenticemail.dev/mcp).
What tools does the AgenticEmail MCP server expose?
AgenticEmail exposes 9 tools: create_inbox, list_inboxes, list_threads, get_thread, list_messages, and 4 more. Their descriptions and schemas cost roughly 374 tokens of context every time the server is loaded.
Does the AgenticEmail MCP server require authentication?
Its publisher declares that AgenticEmail requires credentials, so you will need to authorise it in your MCP client. We have not been able to confirm that against the live endpoint.
Is the AgenticEmail MCP server still maintained?
AgenticEmail has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 5 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
