}Forwards one message to new recipients and returns
Set this endpoint up in your agent →
message_id and thread_id. 🔴 This sends real email and it cannot be recalled, and it passes along the original content including attachments — check what you are forwarding with get_agentmail_inbox_message first. Every AIsa caller shares one AgentMail account, so this reaches inboxes other callers created. To answer instead of forward, use post_agentmail_inbox_message_reply.
Example
curl -X POST "https://api.aisa.one/apis/v1/agentmail/inboxes/{inbox_id}/messages/{message_id}/forward" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY"
// Copy this whole block into Claude Code, Codex, Cursor or any coding agent.
// It carries everything needed to connect, authorize and run this example —
// no key to paste, one click of Allow in the browser.

// ── for the agent ─────────────────────────────────────────────────────────
// Register the AIsa MCP server, then call its `use` tool with the JSON above.
// name aisa
// endpoint https://mcp.aisa.one/mcp
// transport streamable-http
// auth OAuth. The server publishes RFC 9728 metadata, so open a
// browser and the user clicks Allow once — nothing to paste.
// If AISA_API_KEY is set, send it as a bearer header instead.
// Use your own MCP mechanism, not a hand-edited config file:
// Codex codex mcp add aisa --url https://mcp.aisa.one/mcp
// Claude Code claude mcp add --transport http -s user aisa https://mcp.aisa.one/mcp
// Cursor / VS Code a "url" entry for https://mcp.aisa.one/mcp in the MCP config
// The server lists five tools over https://mcp.aisa.one/servers worth of APIs:
// search, get_details, use, batch_use, list_categories. search and
// get_details are free; use is billed per call and max_price_usd refuses
// anything above the cap before spending. This operation's full contract —
// every argument, the response shape, the price and the pitfalls — is at
// https://aisa.one/docs/api-reference/agentmail/post_agentmail-inboxes-inbox-id-messages-message-id-forward.md
// Then run the call and show me the result.
