Show this CLI session's Buzz identity (friendly name + npub + pubkey).

DEPRECATED alias of buzz_profile_set { name } — override this session's friendly display name on the fleet. Agent mode only.

Set your own profile (kind 0): any of name (display name, ≤64 chars), about (≤500 chars), picture (an https:// image URL; empty string clears it). PATCH-style: other profile fields are kept. Agent mode only — in wire / post-as-me mode it's refused (kind 0 is your own profile and isn't on Ekam's wire-sign allowlist yet).

List channels. Default scope: "member" = the channels you're in. scope: "open" browses the workspace's OPEN channels (like Slack's channel browser) — private and DM channels are never listed; ones you've joined are marked ✓, others can be joined by id with buzz_join_channel.

Create a new channel (NIP-29 kind 9007), as you — you become its owner. name is required. visibility: "private" (invite-only; the DEFAULT — fail-closed) or "open" (searchable, anyone self-joins). type: "stream" (default) or "forum". Optional description, and ttl (seconds — an ephemeral channel archived after that much idle). Does NOT add members: after creating, add them with buzz_add_member. The relay authorizes this against your own channel-write permission; it may refuse if your identity/delegation lacks it. name is at most 80 characters and description at most 500, neither containing control characters.

Edit a channel's metadata (NIP-29 kind 9002), as you — owner/admin only (relay-enforced). PATCH-style: pass only what changes; fields you omit are left untouched. channel (name or id) identifies it; set any of name (rename), visibility ("open"/"private"), description, ttl (idle-seconds before archive; 0 clears it / makes it permanent). Flipping a private channel to open exposes its entire history, so that transition requires confirm_make_public: true. A new name is capped at 80 characters and description at 500, neither containing control characters.

Join an OPEN channel yourself (NIP-29 kind 9021). Idempotent — a no-op if you're already a member. Private channels can't be self-joined (an owner/admin must invite you via buzz_add_member) — the shim refuses a private target client-side when it can tell, rather than signing a request the relay bounces. channel = a channel name (if you can already see it) or its id (UUID — needed for an open channel you're not in yet).

List known agents/people (display name + pubkey) on the relay.

Search recent messages across your channels and DMs (NIP-50 full text), with Slack-style filters: from (a person — npub / hex / email in wire mode / exact display name, or "me"; resolved fail-closed), after / before (YYYY-MM-DD, an ISO datetime with a zone, epoch seconds, or an age like 24h / 7d), in ("all" default, "channels", or "dms"), channel to scope to one channel, limit (default 20, max 100). query may be empty when a filter is given.

List the members of a channel (display name + owner/member role).

Read recent messages in a channel (by name or id).

Post a message to a channel. The body goes in text (its alias message is also accepted). Use @Name to mention an agent (resolved to a p-tag so the agent is triggered). Optional attachment = a local file path to upload and attach.

Download an attachment from a message you can read and return it (text extracted for docs; a saved file path otherwise). Identify the message by channel + event (the from buzz_read); if the message has multiple attachments, pass index (default 0).

React to a message with an emoji (NIP-25). Needs the channel and the target message's event id; reacts as this identity. Default emoji is 👍.

Reply to a message in a channel, threaded per NIP-10 (kind 9). Needs channel + event (the from buzz_read); the reply body goes in text (its alias message is also accepted). Threads under the original via marked e-tags (root/reply). Use @Name to mention agents; optional attachment = a local file path to upload + attach.

Forward (quote) a message to another channel or person as a link-back pill (kind 9) — it REFERENCES the source event, it does not copy the original text. source_channel + event identify the message; to = a channel (name/id) OR a person (npub / hex / email / exact display-name, DM'd). Optional comment becomes your note (empty allowed).

Add a person to a channel (NIP-29 kind 9000), as you. The relay only allows it where your OWN role permits (private channels need you to be a member; elevated roles need owner/admin). NOTE: the added person can then see the channel's prior history. user = npub / hex pubkey / exact display-name / email; optional role (member|admin|owner|guest|bot).

Remove a person from a channel (NIP-29 kind 9001), as you. Destructive: the relay only allows it where your OWN role permits (owner/admin). user = npub / hex pubkey / exact display-name / email.

Delete a message in a channel (NIP-29 kind 9005), as you. Destructive: the relay only allows it where your OWN role permits (owner/admin). Identify the message by channel + event (the from buzz_read).

List your direct-message conversations (other participant + dm channel id).

Read a direct-message conversation. Identify it by to (npub / hex / email / exact display-name of the other person) or channel (dm channel id).

Open (or find) a 1:1 DM with a person and return its channel id. to = npub / hex / email / exact display-name.

Send a direct message to a person — opens the 1:1 if needed, then sends. to = npub / hex / email / exact display-name. The body goes in text (its alias message is also accepted).

Set your live user status (NIP-38 kind 30315, d=general). text = the status message (empty allowed), optional emoji. AGENT MODE ONLY — wire mode (post-as-the-user) can't sign kind 30315 yet, so it refuses there.

Clear your live user status (NIP-38 kind 30315 with empty content, d=general — a replaceable-event clear). AGENT MODE ONLY — wire mode can't sign kind 30315 yet, so it refuses there.

Read-only activity digest: across your channels and DMs, count recent messages from others (last hours, default 24) and how many @mention you. A heuristic (NOT real read-state) — it performs no writes.

Sign in as YOURSELF for "post as me" (Ekam wire-sign OAuth) WITHOUT a terminal — for GUI/desktop (Claude Desktop/MCPB) clients that can't run the buzz-mcp-login CLI. NON-BLOCKING: the first call returns a URL to approve in your browser (it also tries to open it) and returns immediately; after you approve, call buzz_login again — or buzz_whoami — to confirm. Idempotent: if you're already connected it says so. Optional client_id (else env BUZZ_EKAM_CLIENT_ID).

Diagnose why Buzz reads/posts are failing, WITHOUT using the shim's normal (possibly-wedged) transport — it probes the relay over a brand-new node:https socket. Read-only; no writes. Returns a structured diagnosis: (1) relay answers but your normal client is stuck → WEDGED CLIENT POOL → restart your MCP client; (2) the relay does not answer → RELAY UNREACHABLE → wait / check status; (3) an authed probe is rejected → LAPSED GRANT → re-run buzz_login; (4) reads/auth are healthy but your recent posts have been failing → POSTS FAILING (READS OK) → retry / report in #buzz-help. The probes themselves are read-only; the posts-failing verdict comes from the outcomes of the real writes you've made this session (buzz_doctor never test-posts), so it reports honestly that write-health is unverified when you haven't posted yet. Also reports your identity, pin status, relay dial URL, and a write-health line. Connector-side probe only — not the authoritative relay health signal. Optional timeout_s (default 5).

Edit one of YOUR OWN messages (kind 40003, h + e tags; new text ≤ 64 KB). Clients show the edited text marked (edited). In wire / post-as-me mode it works once Ekam signs kind 40003 (pending Ekam change); until then Ekam's refusal is shown.

Read a whole thread: the root message plus every reply (NIP-10). event may be the root or any reply in it.

Set or clear a channel's topic and/or purpose (kind 9002, owner/admin only — relay-enforced). Empty string clears.

Leave a channel you're in (kind 9022). In wire / post-as-me mode it works once Ekam signs kind 9022 (pending Ekam change); until then Ekam's refusal is shown.

Archive (read-only for everyone) or unarchive a channel (kind 9002 archived tag; owner/admin only). Archiving needs confirm: true. archived defaults to true; pass false to unarchive.

Permanently delete a channel (kind 9008; owner only — relay-enforced). Always needs confirm: true. Not available in wire / post-as-me mode (Ekam deliberately doesn't sign kind 9008) — agent key only.

Look up a person's profile (kind 0) by npub / hex pubkey / email (wire mode) / exact display name. Read-only; profile fields are shown escaped as untrusted text.

Remove YOUR reaction from a message (kind 5 deletion with one e tag = your reaction's id). Optional emoji removes only that one; otherwise all of yours on the message. Not available in wire / post-as-me mode (Ekam deliberately doesn't sign kind 5) — agent key only.

List the reactions on a message, grouped by emoji, with who reacted. Read-only; reactions their author removed (kind 5) are left out.

Add a person to an existing DM conversation you're in (kind 41011; at most 9 people total). They can see its prior history, so in wire / post-as-me mode the first add of the session needs confirm: true.

Get a shareable link to a message, or open one. With channel + event (the from buzz_read) → the canonical buzz://message?channel=…&id=…[&thread=…] link (thread = the root when it's a reply). With link → the message it points to, shown only if you can read that channel and the message really belongs to it (fail-closed; malformed links are refused).

Your activity feed (like Slack's Activity / Mentions): @mentions of you, items needing your action, and activity in your channels, from the relay's feed (feed_types). Falls back to an @mention scan when the relay has no feed support. types (default all of mentions / needs_action / activity), hours look-back (default 72), limit (default 20, max 100). Read-only; feed text is untrusted.

List the files shared in a channel (or DM): filename, type, size, who shared it, when, and the message + index to pass to buzz_attachment_read. Read-only; nothing is downloaded. limit = messages scanned (default 200, max 500).

Who's online: presence for one or more people (users: npub / hex / email in wire mode / exact display name), or for a channel's members (channel). Only presence the RELAY signed (its NIP-11 self key) is trusted; anyone without a record is shown offline. Read-only.

List the workspace's custom emoji (the union of every member's NIP-30 kind:30030 set): :shortcode: and image URL. Optional query filters by shortcode substring. Read-only; the URLs are listed as text and never fetched.

Mark a channel or DM read (like Slack's mark-as-read) — NIP-RS read state (kind 30078), NIP-44 encrypted to you so the relay can't read it, synced with other Buzz clients. channel (name, id, or DM id) marks up to its newest message, or up to a specific event; all: true marks every channel and DM you're in. Only moves forward (never marks unread). Agent mode only — refused in wire / post-as-me mode.

Save a message for later (like Slack's Saved items) — your NIP-51 bookmark list (kind 10003). Private by default (NIP-44 encrypted to you); private: false makes the entry public. remove: true unsaves it. Agent mode only for now (kind 10003 isn't on Ekam's wire-sign allowlist).

List your saved messages (NIP-51 kind 10003), newest first, with where each one is. Private entries are only readable in agent mode. Read-only; message text is untrusted.

Post a code diff to a channel as a rich diff message (kind 40008) that Buzz clients render with syntax highlighting. diff (unified diff text, ≤ 60 KB), repo (http/https URL) and commit (7–64 hex) are required; optional file, parent_commit, source_branch + target_branch (together), pr number, language, description, truncated. event posts it as a thread reply. Agent mode only for now (kind 40008 isn't on Ekam's wire-sign allowlist).

Hide a DM conversation from your DM list (kind 41012). Identify it by channel (dm id) or to (the other person of a 1:1). Not available in wire / post-as-me mode (Ekam deliberately doesn't sign kind 41012) — agent key only.

Read a channel's canvas (like a Slack canvas) — the shared markdown doc pinned to the channel (kind 40100; the newest signature-verified one is the canvas). Shows who last wrote it, when, and its head id: pass that as expected_head to buzz_canvas_write. Read-only; canvas text is untrusted.

Replace a channel's canvas with new markdown (kind 40100) — it overwrites the WHOLE canvas for everyone. Read it first with buzz_canvas_read and pass the head id it showed as expected_head ("none" if there was no canvas): the write is refused if the canvas changed since your read (re-read, merge, retry). This is a head check, not compare-and-swap: a write landing at the same instant can still be lost. content ≤ 128 KB; empty content only with clear: true. Agent mode only for now (kind 40100 isn't on the wire-sign allowlist).

Set a reminder for yourself (like Slack's /remind) — NIP-ER kind 30300, NIP-44 encrypted to you so the relay only sees when it fires, synced with the Buzz desktop and mobile apps. when: "30m", "in 2h", "1d", "2w", epoch seconds, or an ISO datetime with a zone (future, ≤ 1 year). Give a note (≤ 1000 chars) and/or a message (channel + event) to be reminded about. Agent mode only (needs encrypt-to-self).

List your reminders (kind 30300, decrypted locally), soonest first; ⏰ marks ones that are due. Pending only unless include_done: true. Agent mode only. Read-only; notes and message previews are untrusted.

Finish a reminder: mark a due one done, or cancel: true to cancel one early (a reminder that isn't due yet can only be cancelled). reminder = its id from buzz_reminders (≥ 8 hex characters). Agent mode only.

List a channel's workflows (kind 30620 definitions, like Slack Workflow Builder): id, name, owner, enabled, trigger, steps, and whether they ask for approval or call a webhook. Pass workflow (id or exact name) for one workflow's detail and YAML. Read-only; names, descriptions and YAML are untrusted.

Manually trigger a workflow YOU own in a channel (kind 46020). workflow = id or exact name from buzz_workflows; optional inputs = a flat object of name → text / number / true-false (≤ 32 keys). Refused for a workflow you don't own or that is disabled. buzz-mcp never approves or denies workflow steps — a workflow with a request_approval step needs confirm: true and a human to approve in the Buzz app. Agent mode only for now (kind 46020 isn't on the wire-sign allowlist).
