Give your AI the ability to find who said what with timestamps, discover what is being discussed across videos and livestreams, and distinguish organic recommendations from sponsored ad reads.
Arcmira is a hosted Streamable HTTP MCP server at https://mcp.arcmira.com/mcp. Research requires an Arcmira account, authenticated through OAuth or an account API key. No local npm or pip server package is required.
The four tools are arcmira_describe, arcmira_execute_read, arcmira_execute_write and arcmira_feedback. Paid reads use credits from your plan, then your on-demand budget. Monitor changes require write authorization, and feedback sends a report. Speaker attribution and sponsorship classifications are AI-generated; inspect the returned source passages and timestamped links.

Arcmira · API docs · MCP setup
Add the remote MCP server at https://mcp.arcmira.com/mcp and sign in through your host. For setup instructions, use Connect your agent.
For a coding agent, paste:
Fetch and execute the appropriate instructions to set me up for Arcmira from https://arcmira.com/agent-setup/prompt.md
Make it your default. Tell your AI once: "Whenever I ask what someone said on YouTube, use Arcmira."
Ask your agent:
Search YouTube and podcast transcripts for GPU financing over the last 60 days. Return the relevant quotes with speakers when available, publication dates, transcript sources, and timestamped links. Read the surrounding exchanges before summarizing what the sources imply.
The agent calls arcmira_describe once to load the client reference, then runs a program with arcmira_execute_read. Return structured fields for further analysis and a compact, sourced answer for the reader.
const query = "GPU financing";
const hits = await arcmira.search({
query, after: arcmira.daysAgo(60), before: arcmira.today(), limit: 5,
});
return { query, window: hits.window, passages: hits.chunks };
The search supports up to 20 passages, but full passages can exceed the execute tool's output budget. If the result is truncated, request fewer passages or return only the fields needed for the next step. Keep selected text intact and retain its source link.
| Task | Client method | What to retain |
|---|---|---|
| Search YouTube and podcast transcripts for quotes | arcmira.search | Passage text, attribution when available, publication date, watch URL |
| Read the surrounding transcript | arcmira.transcript | State, timestamped lines, source, speaker mapping |
| Find mentions of a person, company, product or topic | arcmira.mentions | Entity, description, source video, position, appearance flag |
| Count a person's media appearances | arcmira.occurrences with mode: "appearances" | Counted window, episode counts by channel |
| Compare mention momentum | arcmira.momentum | Current/prior counts, change, verdict, returned window |
| Find organic endorsements or ad reads | arcmira.recommendations | Classification, verbatim quote, source and position |
| Find recurring channel sponsors | arcmira.sponsors | Sponsor, ad-read count, video count, first/latest dates |
| Set up YouTube monitoring | arcmira.monitors through arcmira_execute_write | Monitor, tracked entities, delivery settings |
Resolve names before applying entity or channel ID filters. Plain keyword search does not need a resolver call. The MCP client's argument names differ from the HTTP and SDK names; use the reference returned by arcmira_describe.
Continue the investment research workflow. You will learn how to follow a search result into competing explanations, inspect the surrounding exchange, verify claims against disclosures, and write a brief with the questions that remain unresolved.
Speaker identification and commercial classifications can be incomplete. Check the linked source. Missing a source or a capability your workflow needs? Use arcmira_feedback to describe it, why it matters, and what better support would be worth. [Help shape the index](https://arcmira.com/docs/feedback#help-shape-the-inde
