Common questions
Is MCP Charts safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 33 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

MCP Charts
The MCP for MCPs. MCP Charts is a hosted, read-only MCP server. Your agent can use it to find the right MCP servers, agent skills, plugins, agents, prompts and rules for a task.
- Endpoint:
https://mcpcharts.com/mcp - Transport: Streamable HTTP
- Auth: none. You don't need an account or API key.
- Official MCP Registry:
com.mcpcharts/mcpcharts
This repository holds connection docs and registry metadata only. The service is hosted, so there is nothing to install or run locally.
Connect
Claude Code
claude mcp add --transport http mcpcharts https://mcpcharts.com/mcpCursor, VS Code, Cline, Windsurf and other `mcp.json` clients
{"mcpServers": { "mcpcharts": { "url": "https://mcpcharts.com/mcp" } } }
Some clients use "type": "streamable-http" or "transport": "http" alongside url. Check your client's remote-server docs.
Claude.ai / ChatGPT: add https://mcpcharts.com/mcp as a custom connector.
Tools
All tools are read-only. They never install or execute anything.
| Tool | What it does | Inputs |
|---|---|---|
recommend_resources | Gives a ranked shortlist for a task. Keyword relevance comes before repository stars. | task, optional client, type, limit (1–8) |
search_resources | Searches keywords across all resource types, up to 24 results per page. | query, optional type, page |
get_resource | Returns compatibility evidence, freshness and the upstream setup link for one catalog entry. | id |
type is one of skill, mcp, plugin, agent, prompt or rule.
Example prompts
- "Find me an MCP server for querying Postgres from Claude Code."
- "What skills exist for writing Playwright tests?"
- "Recommend a plugin for reviewing pull requests in Cursor."
How the catalog works
The catalog is refreshed continuously from public sources, including the official MCP Registry. Repository stars and activity describe repositories, not individual resources. Client compatibility comes from manifests and registry declarations; MCP Charts doesn't run runtime tests. Check requirements such as "free" or "local-only" upstream before you install anything.
Requests are rate-limited and results are bounded.
