Common questions
Is Triplex schema contracts 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.48.1) reached the registry 14 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Rust on your computer.
What can I use instead?

README from the maker
Open the README
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
triplex-mcp
MCP (Model Context Protocol) server over SchemaCast, stdio transport only. A coding agent (Claude Code or any other MCP client) launches this as a local process and talks to it over its own stdin/stdout, same trust boundary as apps/triplex-cli: no network, no server, nothing here reads bytes over the wire.
Tools
schema_infer(path, sample_rows?): infers a schema contract from a local file (triplex_schemacast::infer_schema_from_path).schema_validate(schema_path, input_path, sample_rows?): checks a local file against a.triplex.yamlcontract (triplex_schemacast::validate_path).
Both are read-only and take a local file path. anonymize isn't exposed yet.
Run
cargo install triplex-mcptriplex-mcp
From a checkout of this repository: cargo run -p triplex-mcp.
Speaks newline-delimited JSON-RPC 2.0 on stdin/stdout. Point an MCP client's stdio transport at this binary. No flags, no config file.
Build/test
Ordinary workspace crate: cargo build -p triplex-mcp, cargo test -p triplex-mcp, cargo clippy -p triplex-mcp --all-targets. Covered by the root cargo test --workspace/CI already; there is no separate Makefile target.
MCP registry
The official MCP registry lists servers by name and points MCP clients to the package to install; for this server, that package is this crate on crates.io. The registry confirms that the crate belongs to the entry by reading the line below in the published README, so it has to stay:
mcp-name: io.github.triplexanalytics/triplex-mcp
