Use Claude Fable 5.2 on Your Meeting Notes (MCP Setup)

Claude Fable 5.2, released by Anthropic on 9 November 2026, is built for demanding reasoning and long-running agent work, according to Anthropic’s model page. To use it on your meeting notes, connect Reline’s MCP server to Claude (Customize, then Connectors), approve access on Reline’s consent screen, pick Fable 5.2 in a new chat and ask about your meetings.

Anthropic aims Fable 5.2 at its most demanding technical work and still recommends Claude Opus 5.5 as the starting point for most coding and knowledge tasks. Neither the announcement nor the model pages mention meetings. What they do say matters most when one job spans many meetings and should end in a finished document.

Claude Mythos 5.2, released the same day, is the same underlying model with different safeguards. Anthropic offers it only to vetted organizations through its verification programs for cybersecurity and life sciences work, so for meeting notes Fable 5.2 is the one you can pick.

From Anthropic’s help center, as of 9 November 2026:

• Free: no Fable models. You can still add one custom connector, such as Reline, and use it with Claude’s other models.
• Max, Ultra, premium Team seats and premium seat-based Enterprise seats: Fable is part of the plan for up to 50% of your weekly usage limits. Past that, pay with usage credits or switch models.
• Pro, standard Team seats and standard seat-based Enterprise seats: Fable runs on pay-as-you-go usage credits. Launch offer: until 16 November 2026 at 11:59 pm PT, Pro plans and standard Team seats get up to 50% of their weekly usage limits on Fable at no extra cost. Accounts with paid billing in place before 10:00 am PT on 9 November 2026 also get one Fable limit reset.
• Usage-based Enterprise and the API: standard API rates. On Enterprise plans, Fable 5.2 stays off until an admin enables it.

Nothing extra on the Reline side: the MCP server is part of every Reline plan, Free included.

1. In claude.ai or the Claude desktop app, open Customize, then Connectors. In the desktop app, Customize sits in the sidebar.
2. Select Discover, type Reline in Search connectors and open the listing. Reline is a Community connector: Anthropic screened it before listing it but has not reviewed it in depth, and Claude shows a reminder saying so.
3. Select Connect to Claude. On Team and Enterprise plans, an Owner adds Reline for the organization first; on Team, a member without that permission sees Request instead, which asks the Owners.
4. Reline’s consent screen opens, in your browser if you started in the desktop app. Sign in to Reline, or click “Continue in app” if you only use Reline’s desktop app. Check that “Connecting as” shows the right account.
5. Under “Choose workspaces”, keep only the workspaces Claude may reach (up to 10). Leave “Create and edit as you” on for write access, or switch it off for read only. Click “Allow access”.
6. Back in Claude, Reline is listed under Your connectors as Connected. Start a new chat, pick Fable 5.2 in the model menu, open + and then Connectors, and check that Reline is on.
7. Ask about a meeting. Before Claude uses a Reline tool, it can ask for your approval: Allow once, or Always allow for that tool.

Prefer the URL? In Customize, then Connectors, choose Add custom connector and enter https://mcp.reline.so/mcp. Keep the /mcp at the end: in our tests, the bare domain fails before the consent screen opens. Anthropic offers custom connectors on every Claude plan, Free included (one connector there).

In Claude Code, the connectors you added in claude.ai are available when you sign in with your Claude account. To add Reline there on its own, run claude mcp add --transport http reline https://mcp.reline.so/mcp, then /mcp to sign in and /model fable to switch to Fable 5.2 (Claude Code 2.1.321 or later). A server added this way loads only in the current project unless you add the option --scope user.

Claude chooses the tools and their order, and each call shows in the chat. Below is what it typically calls for each prompt and what comes back. The first five need read access only. The last two write, so they need “Create and edit as you” on, edit or comment access to the note, and your approval.

Claude calls get_company, which returns the people you know at Acme from your People list in Reline, your next meeting with any of them, the open action items in notes with them and those notes, newest first. It opens the three newest with fetch or get_note and reads get_transcript where the brief needs exact words. The brief comes back in the chat with a link to each note. If Acme is not in your People list, list_meetings can filter by an attendee’s email instead.

Claude finds the folder with list_folders, then calls list_meetings with that folder and a start date, asking for each meeting’s latest summary (shortened) and up to 10 action items. Where a decision needs checking, get_transcript returns lines shaped “[m:ss] Speaker: text”, each with a link that opens the transcript at that line. Twenty meetings in one answer is the kind of long, many-step job Anthropic built Fable 5.2 for.

Claude calls list_recent_meetings to find the call, then get_note with the attendees and action items included, and get_transcript if a commitment needs its exact wording. The draft stays in the chat: Reline has no tool that sends email, so you paste it into your mail app and send it yourself.

Claude calls get_company for each customer, then search for themes such as pricing or integrations. Search ranks notes by keyword or by meaning, and a transcript match comes with up to three lines that contain the words, each with its time and a link. Claude reads the full context with get_transcript before it fills the table.

Claude calls list_action_items with the owner set to me and moments included, so each item carries the point in the recording where it was said, when Reline has one. For promises that never became action items, it reads your own lines with get_transcript filtered to the speaker “Me”, which is your microphone on recordings without the beta voice separation, and searches for phrases like “I’ll send”.

Claude reads with get_transcript, shows you the list, then calls save_action_items, up to 50 rows per call. You get back each saved item with its owner, due day and link, and any row that failed with the reason. If the note’s folder is connected to Linear, Notion or Slack, the new items reach it as they would from the app.

Claude finds the line with search or get_transcript, then calls add_comment on that transcript moment. Sam is notified in Reline and by email, and the comment shows under your name, marked as written via Claude.

With read access, Claude can:

• Search your notes by keyword or by meaning, across titles, note text, transcripts and summaries, narrowed by folder or date.
• List notes and recorded meetings by folder, date or attendee, and count notes against what your account can see.
• Read a note as markdown with its latest summary, and read transcripts line by line with [m:ss] times.
• List action items with owners and due dates, look up people and companies in People, and read your Reline Inbox without marking anything read.
• Read the events on your connected Google or Outlook calendar. It never edits them or answers invitations.

With “Create and edit as you” on, it can also create notes and folders, add text to the top or end of a note, rename a note or file it in a folder, add or change action items and mark them done, comment on a note’s words or a transcript moment, book a meeting on your Reline calendar (not Google Calendar or Outlook, and no invitation is emailed) and regenerate a note’s AI notes with a template. Reline’s consent screen spells out the rule: teammates are notified as if you did it and see the change under your name, marked via the AI tool.

What it cannot do, by design: delete anything permanently, archive or share a note, or change permissions and members. It reaches only the workspaces you ticked and only the notes your account can open, so a teammate’s private note stays private. No audio file passes through the connector: Claude gets text, and each link opens the note in Reline.

Reline’s built-in AI, which writes its summaries and answers its “Ask anything” chat, is separate from Claude, and connecting Claude changes nothing about it. Fable 5.2 writes what you read in the Claude chat and anything Claude saves back through a write tool. One case to know: if you ask Claude to regenerate a meeting’s notes, it calls Reline’s generate_summary tool, and Reline’s own AI writes them, not Fable 5.2.

Reline sends Claude only what each tool call returns, such as note text, summaries, transcript lines, action items, people and calendar events, and only from the workspaces you approved and the notes your account can open. Every connection is listed in Reline under Settings, then Connectors, in the MCP section, and “Revoke” cuts it off at once. If you connect from two devices you get two connections, and revoking one leaves the other working.

What Anthropic says it does with that text, as of 9 November 2026:

• Training on consumer plans (Free, Pro and Max): your chats are used if you turn on Model Improvement in Claude’s privacy settings, send feedback with the thumbs buttons or opt in another way, and a chat flagged for safety review can be used too. For Model Improvement and feedback, Anthropic says the data excludes raw content from connectors, remote MCP servers included, unless it is copied directly into the conversation.
• Training on commercial products such as Claude for Work and the API: inputs and outputs are not used by default.
• Retention for Fable 5.2: Anthropic lists it as a Covered Model, so prompts and replies are kept for at least 30 days by default and then deleted automatically, unless a safety investigation or the law requires longer. Zero data retention is generally not available for it.

Two settings worth using. For a sensitive client, tick only that client’s workspace on Reline’s consent screen, or connect read only. And set Reline’s write tools to Needs approval under Customize, Connectors, Reline, Tool permissions. Anthropic also notes that in Research mode Claude can call connector tools without further approval, so keep write work for a normal chat.

• Fable 5.2 needs a paid Claude plan, and on Pro and standard Team seats it runs on usage credits once the launch offer ends on 16 November 2026.
• Claude reads only what Reline captured. Reline records on a computer, with the desktop app for Mac, Windows and Linux (beta) or in a browser tab. There is no Reline mobile app, so calls you take on your phone are not in Reline.
• Speaker names are not automatic. Reline tells your microphone (Me) from the call audio, and the beta “Separate speakers” and “Shared mic” options number the voices, which you name yourself. Claude can only put a name on a line if the transcript has one.
• Fable 5.2 costs twice as much per API token as Opus 5.5, and Anthropic suggests starting most knowledge work on Opus 5.5. Keep Fable for the jobs that span many meetings.
• Answers can still be wrong: a model can misread a number or a name. Check the moment before you act on it.

Claude can only be as good as the notes underneath. Capturing them in Reline looks like this:

1. Install the Reline desktop app for Mac, Windows or Linux (beta), or open Reline in a browser tab. On a Mac, the first run asks you to click “Allow microphone”, then “Allow system audio”; on Windows and Linux (beta) it starts with a sound check.
2. When a call starts, click “Quick note”, or the card the desktop app shows when Zoom, Teams, Meet or another call app starts using your microphone. Nothing joins the call: Reline records your microphone and your computer’s audio and transcribes live, in 60+ languages.
3. Type rough notes as you go. Reline treats what you type as the points that matter most to you.
4. When you stop, click “Generate notes”. A recording started from the card stops when the call ends and writes the notes on its own.
5. For a question about that one meeting, use “Ask anything” at the bottom of the note: the answer quotes the transcript lines with their [m:ss] times, and you can click one to hear it. For questions across many meetings, ask Claude with Fable 5.2.

With no bot in the call, nobody sees a notetaker, so telling people is your job: say at the start that you are taking notes with AI. Several US states require every party to agree before a call is recorded, and in the EU you need a lawful basis under the GDPR, so check the rules where everyone on the call is. This is not legal advice.

Price, as of November 2026: Free includes 10 hours of transcription and up to 1 hour of recording per note, with no card. Professional is $15 per user a month, or $12 a month billed yearly.
