IDs-LE
Find every UUID, ULID, NanoID, ObjectId and Snowflake, and decode the time inside it.
The command-line tool and its MCP server are written and tested. The VS Code extension is not written yet, so there is nothing to install from the Marketplace or Open VSX — those links appear here when it ships rather than before.
No editor in the loop? ids-le mcp runs the same engine as an MCP server, so an agent can call extract_ids over stdio, with no editor and no Node, and cargo install ids-le puts the same check in a terminal. Every way to install it.

What IDs-LE does
An identifier usually records when and where something was made, and almost none of that is readable by eye. IDs-LE finds every UUID, ULID, NanoID, MongoDB ObjectId and Snowflake in a tree, says what each one is, and decodes the timestamp inside the ones that carry a clock — six bit layouts over three epochs, one of which starts in 1582, all reported as the same ISO-8601 UTC string. It refuses rather than guesses: thirty-two hex digits are an unhyphenated UUID and an MD5 digest in equal measure, so that run comes back as a row with a named reason instead of a confident wrong answer.
What people use it for
Date an id with no lookup
A v7 UUID, a ULID, an ObjectId or a Snowflake in a log resolves to an instant without a database in the loop.
Stop a regex mislabelling a digest
A run that fits two schemes is reported as ambiguous, not classified as whichever pattern happened to match first.
Sweep a repo for placeholders
The nil UUID, a v4 that is plainly not random, and a timestamp before 1990 each come back named rather than dropped.
Install IDs-LE
Command lineComing soon
cargo install ids-leNot on crates.io yet — v0.1.0 builds from the repository today, and this command starts working the day it publishes. Follow the repository.
VS CodeComing soon
ext install nolindnaidoo.ids-leThe extension is not written yet, so this id resolves to nothing on the Marketplace. It is the id it will take. Follow the repository.
Cursor / VSCodiumComing soon
cursor --install-extension OffensiveEdge.ids-leSame again for the forks, which resolve Open VSX rather than the Marketplace. Follow the repository.
Zed
ids-le mcpWorks in Zed today — add the command above as a custom MCP server from the agent panel, and extract_ids appears in its tool list. There is no one-click listing in Zed's extension registry yet.
AI agents
ids-le mcpRuns IDs-LE's engine as an MCP server over stdio, so an agent can call extract_ids with no editor and no Node. The binary is the server — there is nothing else to install.
Where it ships
One engine, 6 places to get it. The ids differ by registry — copy the one for the editor you use.
