6 TOOLS AVAILABLE
OUR ASSESSMENT
- Mailgun official maintenance.
- 55 GitHub stars and Apache-2.0 license.
- 2 commits on main in the last 30 days.
- First email-vendor MCP in the directory.
- Domain-scoped key support reduces blast radius.
- Mailgun account required.
- Send-email tool carries reputation risk; agents that loop on send_email can trigger Mailgun spam blocks.
- No streaming receive surface; bounces and complaints surface via list_events polling.
MAILGUN_API_KEY can be domain-scoped or account-wide. Use domain-scoped keys for agent flows to limit blast radius. send_email can dispatch to any address; rate-limit at the agent layer or use an allowlist of recipients for high-frequency flows.
Teams sending transactional email through Mailgun who want agents to handle support replies or list management; SaaS operators triaging bounces and complaints from inside an agent; growth teams managing Mailgun-driven mailing lists.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
