mcp-server-email
A minimal MCP server demo intended to send email (implemented in Go), but the provided repository content includes no usage documentation or interface details beyond the short description.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No security guidance is available in the provided content. As a result, TLS, auth/authorization, secret handling, and dependency posture cannot be confirmed from observable documentation. Email-sending integrations commonly require careful handling of SMTP/API credentials and recipient content to avoid leakage or injection risks.
⚡ Reliability
Use Cases
- • Demoing MCP tool integration for email-sending workflows
- • Prototyping an agent that can trigger outbound emails via a Go-based MCP server
Not For
- • Production email delivery without verified configuration, security, and operational documentation
- • Use where you need guaranteed compliance features (e.g., audited templates, per-tenant isolation, retention policies)
Interface
Authentication
No authentication method, configuration, or credential handling guidance is present in the provided README/metadata.
Pricing
No pricing information provided (likely open-source demo; actual email sending may incur downstream provider costs, but none are documented here).
Agent Metadata
Known Gotchas
- ⚠ Provided docs do not describe tool names/inputs/outputs, so agent integration may require reading source code and/or guessing schemas.
- ⚠ No rate-limit, timeout, or retry guidance is documented; an agent may need conservative defaults.
- ⚠ No explicit idempotency or deduplication strategy is documented; repeated tool calls could send duplicate emails.
