Radi8

Update fields on an existing plan item in the currently-selected workspace. Only provided fields are changed; others stay as-is. The brief is MERGED, not replaced — only the brief keys you send change; every other key already on the brief is preserved. Use status='done' after the post is scheduled so the item drops off outstanding work, or status='skipped' if it's no longer happening.

edit_plan_item

Edit a scheduled post in the currently-selected workspace. Only posts with status 'scheduled' can be edited — drafts and already-published posts are rejected. Pass any combination of content, scheduled_at, media_asset_ids, or first_comment. Providing media_asset_ids replaces the full attachment list (pass [] to clear).

edit_scheduled_post

Return which Radi8 workspace is currently active for this session — Personal, a specific Company, or null if the user has not chosen yet.

get_active_account

Fetch the active Radi8 brand context for the currently-selected workspace — includes brand voice, content topics, target audience, personas, and tone guidelines. Requires an active account. Returns a readiness block alongside the context, reporting whether the stored context is complete enough to generate against.

get_brand_context

Fetch the active Radi8 brand kit for the currently-selected workspace — the visual identity counterpart to brand context. Includes the color palette (background/ink/accent/muted), typography roles (headline/headline_accent/eyebrow/body with family/weight/style), recurring visual motifs, layout rules, and references to attached logo/wordmark assets. Requires an active account. The reference for any visual or design work in the workspace.

get_brand_kit

Fetch the content strategy for the currently-selected workspace — includes content pillars, preferred channels, posting schedule, business goals, and primary CTA. Requires an active account.

get_strategy

Fetch the monthly content plan object for the currently-selected workspace — the plan container (title, summary, monthly brief, status, date range). Does not include the plan's items, which are fetched separately. Defaults to the current month.

get_plan

Fetch all social media channels connected in the currently-selected workspace. Requires an active account. Only channels in the `connected` list can be scheduled to. A channel in the `needs_reconnect` list has an access token that has expired and cannot be auto-refreshed, so scheduling to it will fail; `setup_url` is where the workspace owner reconnects it.

get_connected_channels

List draft (not-yet-scheduled) posts in the currently-selected workspace, most recently updated first, with each draft's post_id, platform and content.

list_drafts

Fetch the media library for the currently-selected workspace — images and videos with preview URLs. Requires an active account. Each asset returns a media_type ('image' or 'video'); videos also return duration_seconds when known. Videos can only be uploaded via the Radi8 web app (app.radi8.com) — MCP can reference them by media_asset_id once they exist, but cannot create them.

get_media_library

Fetch content plan items for a given month from the currently-selected workspace. Returns all items in the plan (including done and skipped) with their briefs, target channels, scheduled dates, and status. Requires an active account.

get_plan_items

List posts already published to social platforms in the currently-selected workspace, most recently published first. Published posts are immutable. Shows what has already gone out — angles, hooks, CTAs and linked Discover items — so it can be compared with a new draft. Optional platform filter narrows the list to one channel.

list_published_posts

Fetch recently-curated content from the Discover feed in the active workspace. Personal scope returns the user's personal Discover feed; company scope returns the company's Discover feed (never mixed). Discover items are articles, posts, and links the user or company has saved as inspiration. Use these to ground new drafts in topics already on the user's radar — quote them, riff on them, or counter them, and check that you're not posting the same item twice on the same channel. Excludes archived items.

get_discover_items

List scheduled (not-yet-published) posts in the currently-selected workspace, most recent scheduled time first, with each post's post_id, platform, content and scheduled time.

list_scheduled_posts

List the Radi8 workspaces the user can use: their Personal workspace and every Company workspace they belong to. Each company carries `access`: "edit" for an admin, "view" for a member, who can read everything in that company but change nothing. Returns each workspace's id, display name and kind. Content tools work only once a workspace is selected.

list_accounts

Read comments on one of the currently-selected workspace's published LinkedIn posts. Only works for a connected LinkedIn Company Page (org workspace) — LinkedIn restricts reading comments on personal posts. Identify the post by its Radi8 post_id or its LinkedIn post_urn. Returns each comment's URN, author and text.

get_post_comments

Reply to an existing LinkedIn comment (a nested reply) on one of the currently-selected workspace's posts. Provide the comment_urn of the comment being replied to and the reply text. Works for both personal and Company Page connections.

reply_to_comment

Promote an existing draft to scheduled in the currently-selected workspace. The post will be published automatically at scheduled_at via the workspace's connected channel. Requires status='draft'. Scheduling to a channel that is not connected will fail. The post can be returned to a draft at any point before it publishes.

schedule_draft

Create a scheduled post in the currently-selected workspace. Published automatically at the specified time via the workspace's connected channel. Requires an active account. Scheduling to a channel that is not connected will fail. VIDEO: videos cannot be added over MCP — only images. A video must already be in the workspace media library (added at app.radi8.com) and is attached by its media_asset_id. A single video asset on an Instagram post publishes as a Reel; on TikTok it publishes as a standard video. Image posts (Instagram single image or carousel, TikTok photo mode) take any image in the media library. Images are not generated over MCP — the user creates them at app.radi8.com and they appear in the media library. BLUESKY: 300 characters at most, up to 4 images, no video. TIKTOK PRIVACY NOTE: TikTok posts scheduled via MCP publish as PRIVATE (only visible to the user themselves) because TikTok's Content Posting API audit requires the user to pick a privacy level through an in-app picker. A TikTok post that needs to be public, or visible to followers, has to be composed at app.radi8.com, where those privacy options are surfaced.

schedule_post

Attach a logo, wordmark, symbol, or pattern asset to the active brand kit. The asset must already exist in the workspace media library; pass its media_asset_id plus the role. Replaces any existing asset at the same (role, variant) slot. Variants let you store multiple versions of the same role (e.g., a 'light' wordmark for dark backgrounds and a 'dark' wordmark for light backgrounds).

set_brand_kit_asset

Set which Radi8 workspace to use for this session — "personal" or a specific company (by company_id). A company where the user is a member (not an admin) opens view-only: read tools work there, and tools that change anything are refused. The choice persists across tool calls in the session until it is set again.

set_active_account

Convert a scheduled post back to a draft in the currently-selected workspace. Clears scheduled_at and sets status='draft'. Requires status='scheduled' — published posts cannot be reverted. Keeps the content while taking it off the publish queue; the draft can be scheduled again later.

unschedule_post

Update the active brand context for the currently-selected workspace. Provide only the fields you want to change — they are merged into the existing context and saved as a new version (the prior version is archived). Readiness is system-managed and cannot be set directly. Personas, if provided, replace the full personas array. Array fields (topics, expertise, pain_points, value_props, proof_points, cta_preferences, avoid_topics, avoid_claims, approved_claims, content_goals, recurring_patterns) replace wholesale — pass the full intended list, or `[]` to clear. `cta_preferences` and `cta_library` are one field under two names — write either and both stay in sync. `value_proposition` (a one- or two-sentence prose pitch you could read aloud to a prospect) and `value_props` (a list of discrete benefit statements) are INDEPENDENT fields — editing one never changes the other, so don't repeat the pitch as a value_props item. channel_notes is a map keyed by channel name (linkedin, x, instagram, tiktok, facebook, or any custom string the user wants — youtube, substack, podcast, etc.) — values are freeform per-channel guidance that the post generation flow will apply when targeting that channel; channel_notes merges by key (pass empty string to clear a channel).

update_brand_context

Update the active brand kit for the currently-selected workspace. Provide only the fields you want to change — top-level keys are shallow-merged into the existing kit and saved as a new version (the prior version is archived; logo/wordmark assets carry forward automatically). Inside `colors` and `typography`, pass only the roles you are changing; pass null for a role to clear it. Pass full arrays for `motifs` and `layout_rules` — they replace wholesale when provided. Set `archetype` to change the composition look (how headlines are treated) — e.g. 'editorial' for a clean brand that should not get a heavy outline or jittered 'sticker' treatment. Logo and wordmark assets are not set here; they have their own tool.

update_brand_kit

Update the content strategy for the currently-selected workspace. If the workspace has no strategy yet, the first update creates it. Provide only the fields you want to change — they are shallow-merged into the existing strategy (including schedule sub-fields). Array fields (content_pillars, authority_topics, preferred_channels, offers, cta_preferences, objections, substantiation_links, proof_points, do_not_apply) replace wholesale — pass the full intended list, or `[]` to clear. This is a fast-save: the CMO AI review is NOT re-run. The user can re-run the review in Radi8 when ready. channel_strategy is a map keyed by channel name (linkedin/x/instagram/tiktok/facebook plus any custom name the user wants — youtube, substack, podcast, etc.); pass partial updates and they merge by key (empty string clears a channel). do_not_apply is the user's explicit decline list — the CMO will stop re-suggesting items in it. The adoption and advocacy engine facets are nested objects (the growth engines beyond acquisition) — pass only the sub-fields you're changing and they deep-merge into the existing facet, like schedule.

update_strategy

Update the monthly content plan container for the currently-selected workspace. Only title, monthly_brief, and summary are editable — plan status and generated snapshots are system-managed. Items inside the plan are not changed here. If the month has no plan yet, a plan is created for it.
