About
An unofficial, community-built MCP server for exploring genealogy data on Ancestry.com — the largest for-profit family-history platform, with billions of historical records and 100+ million member trees. Ancestry.com does not publish a public API, so this server works by driving the same web session a logged-in user would use: it authenticates with your Ancestry username and password, then exposes tools to search for people by name/date/location, pull detailed person profiles, navigate family-tree relationships across generations, retrieve attached historical records and documents, extract chronological timelines of life events, and generate narrative summaries that stitch a person's records into a readable history. Because there is no first-party API, this is a thin wrapper around Ancestry's own web endpoints rather than a stable, versioned integration — treat it as a personal-use convenience layer, store credentials only in local environment variables (never commit them), and expect it to break if Ancestry changes its site internals. It has effectively no adoption yet (0 GitHub stars) but is the only project found that actually targets the real Ancestry.com service rather than a generic genealogy database, MIT licensed, plain Node.js/JavaScript, installed by cloning the repo and running it locally alongside Claude Desktop or another MCP client.
Trust verdict
How grades are computed →Grade B (79/100, solid) from 1 measured signal, based on repository evidence. Only one signal stands behind it, so treat the grade as provisional.
What was measured
- Repository maintenance55/100 · weight 20
The last push or release is between six and eighteen months old. — last push 2026-01-05.
- Source verification100/100 · weight 25
The repository URL was confirmed to resolve against the live GitHub API and is not archived.
- Provenance65/100 · weight 10
Community-built. That is not a mark against it — most of the ecosystem is community-built — but there is no vendor accountable for keeping it working.
- Listing ↔ repository match100/100 · weight 5
The listing name lines up with the linked repository ctrimm/local-mcp-server-ancestry.
What could not be measured
These contributed nothing to the score — not a penalty, not a zero. They are why the confidence reads the way it does.
- Live MCP handshakeunknown
No remote endpoint to handshake — this server installs and runs locally over stdio, so there is nothing to probe from the outside.
- Measured uptimeunknown
No probe history recorded for this server yet.
- Tool-schema stabilityunknown
Drift is a difference between two successive checks, and this server has none recorded.

Apify MCP Server
The Apify MCP server gives AI agents access to 6,000+ ready-made cloud scrapers, crawlers, and automation tools on the Apify Store — no infrastructure required. Connect to Apify Actors that extract data from social media platforms (Instagram, TikTok, LinkedIn), search engines (Google, Bing), e-commerce sites (Amazon, eBay), maps (Google Maps), and virtually any website. Each Actor runs in the cloud with managed proxies, browser fingerprinting, and anti-bot bypass built in. Use the Apify MCP server to query Actors by task, stream results directly into your AI context, run custom scraping Actors from your Apify account, and chain multiple data extraction steps in a single workflow. Supports tool filtering to expose only the Actors you need, and integrates with Apify's RAG web browser Actor for retrieval-augmented generation use cases.
Browserbase MCP Server
Browserbase MCP and Stagehand MCP are the same server under two names, and this catalog lists both because people search for both — this page is the platform view, /servers/stagehand covers the natural-language automation layer that runs inside it. What Browserbase supplies is the browser itself: a headless Chrome session running in Browserbase's cloud rather than on the machine your agent is on, which is the reason to use it at all. The session is a real, addressable browser with its own residential-proxy and stealth configuration and a recorded replay you can watch afterwards, so an agent's browsing survives being run from a datacenter IP, and a failed run is debuggable after the fact instead of being a black box. Nothing renders on the developer's machine, so a long-running agent is not tied to a desktop staying awake. Browserbase's recommendation is the hosted server at https://mcp.browserbase.com/mcp over streamable HTTP — they operate it and absorb the model inference that the instruction-following tools require. Clients without HTTP transport connect via npx mcp-remote https://mcp.browserbase.com/mcp. Self-hosting installs @browserbasehq/mcp-server-browserbase from npm and needs BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID from your dashboard. Six tools are exposed — start and end for session lifecycle, navigate, act, observe and extract — and they are documented in detail on the Stagehand entry, because the act/observe/extract trio is Stagehand's model rather than Browserbase's. One thing to know before self-hosting: the browserbase/mcp-server-browserbase repository was archived on 2026-07-20 and its README now says it is kept for historical reference and should not be read as representative of the current production service. The npm package still installs and the star count on this page belongs to that archived repo; the hosted endpoint is the path Browserbase actually maintains.
