MCP Junction missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

categories

list_categories

List all directory categories with slugs, names, and active-server counts.

dataset

get_dataset_info

Dataset metadata: entry counts, generation timestamp, source, and licensing terms for bulk or training use.

server

get_server

Get the full directory entry for one MCP server by id ('owner--repo', e.g. 'microsoft--playwright-mcp'). Includes install hint, license, stars, category, and editorial fields. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.

servers

search_servers

Search the MCP server directory by keyword and/or filters. Keyword matches name, description, and GitHub topics. Returns active servers sorted by relevance then stars. Supply at least one of query, category, or topic — with no query, filters alone enumerate a whole category or topic by stars. Data refreshes nightly from the public GitHub API. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.

topics

list_topics

List the curated GitHub topics that have a directory page, with active-server counts. Topics are assigned by repository owners and imported verbatim, so the full dataset carries thousands of them; this returns only the curated subset. search_servers accepts any topic string, curated or not.

MCP Junction — questions

Answers built from our own checks of this server.

What can MCP Junction do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_dataset_info, get_server, list_categories, list_topics, search_servers. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is MCP Junction working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 133 ms. The bar chart above shows every period we have measured.

How do I connect MCP Junction?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does MCP Junction need an API key?

No. MCP Junction completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MCP Junction?

It answers our handshake in 133 ms on average, which is faster than 86% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is MCP Junction open source?

We cannot say either way: written in Python and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
