Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
agenticmail
Give every Claude Code subagent its own real email address and phone number, all self hosted on the user's machine. AgenticMail runs a local mail server (Stalwart in a Colima or Docker container) so each agent has a working `<name>@localhost` inbox, an identity, an API key, and a persona. When a teammate is CC'd on an email they wake up as a Claude Code subagent under your existing Claude OAuth, read the full thread, decide if it is their turn, and either reply to all or stay silent. The thread is the workspace and the audit trail. There is no central orchestrator, no separate Anthropic key per agent, no data leaving your machine, and no polling because everything is push based over SSE. The plugin exposes three skills (`install`, `create-agent`, `coordinate`) that handle the one time bootstrap and let the host session kick off multi agent work with a single email. Behind the plugin sit five npm packages doing the real work: an Express API, an MCP server with 62 tools across email, SMS, contacts, drafts, temp
io.github.vitalio-sh/thunderbird-cli
Give AI agents full read/write email access via Mozilla Thunderbird. Zero credentials.
How to run each

claude mcp add --transport stdio thunderbird-cli -- npx -y thunderbird-cli-mcpCommands built only from what the marketplaces declare; the full set for every client is on each card.

Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only agenticmail asks for
AGENTICMAIL_API_URL
Only io.github.vitalio-sh/thunderbird-cli asks for
TB_BRIDGE_HOSTTB_BRIDGE_PORT
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
