MCP Servers for Claude Code

Claude Code keeps its servers in its own config, managed by claude mcp add. Of the 18 391 we track, 5 181 answer right now without any credentials and 2 768 work but ask for a key. The blocks below are ready to paste — each is built from the address we actually reached, in the format this client expects.

How to add a server to Claude Code

three scopes: this project, this user, or shared through a file in the repository
Add the server

One command, no file to open. For a remote server pass its address and transport; for a local one pass the command that launches it.

claude mcp add <name> --transport http <url>
Check it registered

Lists everything the current scope knows about, with the transport of each.

claude mcp list
Authorise if asked

A server that answers with a challenge instead of its tool list needs credentials. Roughly a quarter of remote servers behave this way, and it means they are running, not broken.

Things that trip people up with Claude Code

Written from how Claude Code reads its config, not from its release notes.

Where does the server end up?
Depends on the scope you choose when adding it. Project scope keeps it to one repository, user scope makes it available everywhere. Picking the wrong one is the usual reason a server "disappears" in another folder.
Why does the command form differ per server?
Local servers are launched as a process, so they need a command and arguments. Remote servers are just an address. The catalogue shows which of the two you are dealing with before you copy anything.
The server was added but no tools showed up
Adding registers the server; it does not prove the server answers. Two thirds of what is in the registry is local, and a local server only exists while the command that launches it works. For a remote one, check whether it responds at all — 2 245 endpoints are listed as active and answer nothing.
How many servers should be connected at once?
Every server contributes its tools to what the model has to choose from, and the median server exposes ten. Four or five servers already means fifty options per request. Add what the task needs rather than everything you have ever tried.
Can the same server be used in another project?
Yes, if it was added in user scope. Project scope keeps it local to one repository — that is the point of having scopes at all, and the usual reason a server seems to vanish elsewhere.
Is it safe to add a server that asks for a key?
Asking for credentials is normal — 2 733 remote servers do. What matters is what it does with them: read the tool list first, note which tools write rather than read, and give the narrowest credentials that work.

Same servers, other clients

the servers are the same — the config format is not
Cursor

Config sits in the project folder, so servers can differ per repository — useful when one project needs database access and another must not have it.

.cursor/mcp.json
VS Code

Works through GitHub Copilot's agent mode. Like Cursor, the config is per workspace rather than global.

.vscode/mcp.json
Codex

The only client here that uses TOML rather than JSON, so a config copied from elsewhere will not work as is.

~/.codex/config.toml
Claude Desktop

One global config for everything, so a server added here is available in every conversation.
