jelly-mcp — Jelly's remote MCP server (letsjelly.com shared inbox)

Bring your own key: create an API token in Jelly (Settings → API Tokens,
Royal Jelly plan) and pass it on every request. This server stores nothing.

Connect from Claude.ai (custom connector — URL is the only config, so the
key rides in it):

  https://mcp.letsjelly.com/mcp?key=YOUR_JELLY_TOKEN

Connect from Claude Code:

  claude mcp add --transport http jelly https://mcp.letsjelly.com/mcp \
    --header "Authorization: Bearer YOUR_JELLY_TOKEN"

Tools (21):
  • list_conversations — List the team's Jelly conversations, newest activity first
  • list_messages — Page through every sent message in a conversation, oldest first (for threads longer than the 20-message embed in get_conversation)
  • list_comments — Page a conversation's internal team comments, oldest first
  • get_conversation — Read one conversation
  • get_message — Load a single message by id (full body, sender, recipients, attachments metadata, and sender-authentication result)
  • list_labels — List all team labels (id, name, color)
  • list_members — List active team members (member_id, name, email, role) — needed for assignment and snoozing
  • list_mailboxes — List the team's mailboxes (default first)
  • find_contact — Look up a Jelly contact by email address
  • get_autoresponder — Show the team's autoresponder (enabled flag + message)
  • add_comment — Add an internal comment to a conversation (visible to the team, never sent to the customer)
  • create_draft_reply — Create a DRAFT reply in a conversation for a human to review and send — API tokens can never send email in Jelly, so nothing goes to the customer until a team member sends it
  • create_label — Create a team label
  • label_conversation — Add a label to a conversation, or remove it with remove=true
  • assign_conversation — Assign a conversation to a team member by member_id OR email (exactly one)
  • unassign_conversation — Remove a member's assignment from a conversation (member_id from list_members)
  • conversation_action — Apply a reversible action to a conversation: archive, unarchive, trash, restore, spam, unspam, or unsnooze
  • snooze_conversation — Snooze a conversation until an ISO 8601 datetime for a specific member (it returns to their inbox then)
  • set_mailboxes — Replace a conversation's entire mailbox set with the given ids
  • create_draft_conversation — Start a brand-new outbound conversation as a DRAFT (not attached to an existing thread)
  • update_draft — Revise an existing draft's body and/or subject (only fields you send change)

Notes:
  • The Jelly API cannot send email — draft tools create drafts a human
    reviews and sends in the Jelly UI.
  • Prefer the Authorization header where your client supports it; ?key=
    exists because Claude.ai custom connectors take a bare URL.

Endpoint: POST / or /mcp (JSON-RPC 2.0).
