Read-only flight fares for AI assistants: the cheapest fares a2bflight has seen on thousands of routes, one-way and round trip, each with the day it was seen. **Cached, not live prices** — each fare links to its route page on a2bflight.com, where the seller shows today's price. **Tools** - `find_airports`: turn a city name into IATA codes, or list airports near a point - `cheapest_routes`: the cheapest fares from an origin (or into a destination), filtered by max price and month - `route_fares`: one airport pair by date and month, one-way and round trip - `where_to_meet`: where 2 to 8 people from different cities can meet cheapest — a weekend, each person's fare, the total, and a link to the group's page with everyone filled in - `meet_link`: the group's page for a place they already picked, on a weekend with fares for everyone No auth, no key. Try: "Cheapest flights from Bangkok next month" · "What does New York to Lisbon cost in November?" · "I'm in New York and my friend is in London — where can we meet cheapest?"
Save AI-agent handoff checkpoints, WorkStash notes, and WorkThreads in a local A2CR workspace.
Read-only A2Me family context tools for AI assistants (members, dates, activity, relationships)
Open E2EE messaging protocol and MCP server so AI agents of different people can talk directly.
[A4B](https://a4b.ai/) is a flat-rate CMMS (asset & maintenance management) that ships a native MCP server — an integration still uncommon in the CMMS category. AI assistants like Claude and ChatGPT can query asset inventory, create and update assets and maintenance tasks, search history, and generate reports. Secured with OAuth sign-in, audit logging, and per-organization isolation. Docs: https://docs.a4b.ai/mcp/

Ask Claude to check any website for the basics Google needs, like "check plumberlogan.com.au" or "why isn't my business showing on Google?". AAA Signal reads the site's public home page, robots.txt and sitemap and replies with a score out of 100, the most important problems first with a plain-English fix for each, and what is already working. It checks: secure connection (https), phone-friendly setup, whether Google is allowed to show the site, page title and Google description, main heading, sitemap, Google Analytics, tap-to-call and contact options, and business details for Google (schema). Every answer includes a link to the full free report on aaasignal.com.au. No sign-in is needed. It is read-only: it never changes the website, and it cannot see rankings, traffic or anyone's private Google data. Built for small business owners and tradies in Australia, and works for any public website.

Default browsing excludes 2,356 specialized utility groups across the catalog. They remain available through keyword search and direct links. This editorial filter does not change the indexed totals or establish publisher quality.
Categories currently cover records matched to our reviewed catalog; other listings remain Uncategorized. Source-only projects have no generated connection option. Browse reviewed official MCPs →
- Glama connectors
API result set; pagination may cap at approximately 1,000 connectors. Not exhaustive.
- Glama source code
Complete chronological source-code catalog response; includes source-reported author classifications, not publisher attestations or ready-to-use endpoints.
- Official MCP Registry
Complete paginated registry response; registry membership is not publisher verification.
- Claude connector directory
Complete public Claude directory MCP components. Source tiers, tools, icons and sign-in hints are declarations, not publisher or runtime verification.
- API Tracker · publisher documentation
Publisher-documented remote presets, local servers and discovery-only announcements reviewed by API Tracker. Discoverability does not establish connection readiness.
- Slack MCP directory
Reviewed additions discovered through the public Slack Marketplace MCP category. Complete discovery inventory is retained separately; membership does not prove external-client compatibility.
Listings are grouped by exact public endpoints, exact package sets, or explicit reviewed identity bindings. Shared names or repositories alone do not merge implementations. Official includes publisher evidence and accepted source author classifications. It does not mean independently verified, runtime-tested or security-certified.
