Overview

Description from the maker (original English)

Track time on usetimebook.com - start/stop timers, log entries, list projects/clients.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: TIMEBOOK_API_URL, TIMEBOOK_WEB_URL

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is Timebook 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?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.0) reached the registry 5 months 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?

Timebook CLI

Command-line client and MCP server for Timebook — track time, manage timers, and expose your Timebook account to AI agents (Claude, Codex, Cursor, …) over the Model Context Protocol.

Install

# one-off

npx @squidcode/timebook login

globally

npm install -g @squidcode/timebook timebook --help

Requires Node.js 18.17+.

Authenticate

timebook login opens your browser, you log into Timebook (or use an existing session) and pick a scope (which clients/projects this token can touch). The browser delivers the token back to a short-lived loopback HTTP listener, which the CLI then writes to a config file with 0600 permissions.

timebook login

The token is stored at:

  • macOS: ~/Library/Preferences/timebook/config.json
  • Linux: ~/.config/timebook/config.json
  • Windows: %APPDATA%\timebook\Config\config.json

The token never leaves your machine after login. To revoke it server-side, visit https://usetimebook.com/settings/api-tokens.

Use it as a CLI

timebook whoami

timebook projects # list projects timebook clients # list clients

timebook start -p "Acme website" -d "Wireframes" timebook status # show running timer timebook stop

manual entries

timebook log -p "Acme website" -t 1h30m -d "Code review" timebook log -p PROJ_ID --start 2026-05-04T09:00 --end 2026-05-04T10:30

timebook entries --project "Acme website" -n 10

edit / delete (any combination of fields; unset ones stay as-is)

timebook entries edit ENTRY_ID -t 2h -d "code review + tests" timebook entries edit ENTRY_ID --start 2026-05-04T09:00 --end 2026-05-04T11:00 timebook entries edit ENTRY_ID -d "" # clear description timebook entries delete ENTRY_ID

Duration formats accepted: 1h, 45m, 1h30m, 1.5h, 1:30, or a bare number (interpreted as minutes — e.g. 90 → 1h 30m).

Edit / delete authorization: an API token can only modify entries it created itself. JWT sessions (the web UI) and admin tokens bypass this rule. Invoiced entries are locked for everyone via the API. A 403 with a friendly message is returned on a denied attempt — fix the entry from the web UI or with the token that created it.

Use it as an MCP server

The same binary speaks MCP over stdio when invoked with timebook mcp. Drop it into any MCP-aware host (Claude Code, Claude Desktop, Codex, Cursor, …):

Claude Code / Claude Desktop
{

"mcpServers": { "timebook": { "command": "npx", "args": ["-y", "@squidcode/timebook", "mcp"] } } }

Or, if installed globally:

{

"mcpServers": { "timebook": { "command": "timebook", "args": ["mcp"] } } }

The MCP server reuses the token saved by timebook login — run timebook login once in a terminal before starting the agent.

Use it as a remote MCP (Claude.ai web)

Timebook also runs as a hosted Streamable-HTTP MCP server at `https://usetimebook.com/mcp` with full OAuth 2.0 (Dynamic Client Registration + PKCE + refresh-token rotation). No CLI install required — Claude.ai discovers it via the standard well-known endpoints:

  • Auth-server metadata: https://usetimebook.com/.well-known/oauth-authorization-server
  • Resource metadata: https://usetimebook.com/.well-known/oauth-protected-resource/mcp

Connect from Claude.ai → Settings → Connectors → Add → paste https://usetimebook.com/mcp. You'll be redirected to Timebook's consent page once, then Claude can use all the same tools listed below. Same OAuth-style permissions you'd see for any first-class connector.

The HTTP endpoint also accepts Authorization: Bearer tbk_* (your existing API token) for any client that prefers token-paste over OAuth — including server-to-server use.

Tools exposed to the model
ToolWhat it does
whoamiCurrent authenticated user (read-only)
list_projectsAll projects in scope (read-only)
list_clientsAll clients in scope (read-only)
get_active_timerThe running timer, or null (read-only)
start_timerStart a timer on a project
stop_timerStop the running timer
log_timeLog a manual entry (duration OR startTime+endTime)
list_entriesRecent entries (default 50, max 500), project + date filters
update_entryEdit one or more fields on an entry (description, duration, startTime, endTime, project, rate). Token must own the entry.
delete_entryDelete an entry. Token must own it. Invoiced entries are locked.
Try it with prompts

Once the MCP server is connected, ask the model in plain English:

  • _"Start a timer on my Acme website project for landing-page wireframes."_
  • _"How much time did I log on the Recycler project last week?"_
  • _"Log 1 hour 30 minutes against ChatNexus from 9am this morning at the Software Development rate, with description 'code review of the auth refactor'."_
  • _"What am I currently working on?"_ — invokes get_active_timer.
  • _"Stop my timer."_
  • _"My last entry on Recycler should be 2 hours, not 1h45m. Fix it."_ — invokes list_entries then update_entry.
  • _"Delete the entry I just made by mistake."_ — invokes delete_entry. Will 403 if the entry was created by a different token (web UI, another agent) — say so to the model so it doesn't keep retrying.

The model picks the right tool, asks list_projects first if it needs to disambiguate a name, and writes through start_timer / log_time / stop_timer.

Privacy

Timebook CLI runs on your machine and only talks to your Timebook account.

  • Authentication: timebook login mints a personal API token via Timebook's OAuth-style consent screen. The token is stored locally with 0600 permissions (~/Library/Preferences/timebook/config.json on macOS, ~/.config/timebook/config.json on Linux, %APPDATA%\timebook\Config\config.json on Windows). It is never transmitted anywhere except https://usetimebook.com (or your override) on outgoing API calls.
  • Telemetry: none. Neither the CLI nor the MCP server reports usage, errors, or analytics anywhere.
  • MCP host data: when you use timebook mcp from inside Claude / Cursor / etc., the MCP host (not Timebook) controls what the model sees. Tool inputs and outputs flow through the host's normal model-context pipeline.
  • Revoking access: visit https://usetimebook.com/settings/api-tokens to revoke the token at any time.

For Timebook's product-level privacy policy, see https://usetimebook.com/privacy.

Configuration

Override the API/web hosts (useful for self-hosted Timebook or local dev):

TIMEBOOK_API_URL=https://api.example.com \

TIMEBOOK_WEB_URL=https://example.com \ timebook login

You can also pass --api-url and --web-url to timebook login once; subsequent commands re-use the saved values.

If timebook login errors with State mismatch or you want to see exactly which requests reach the loopback callback, run with --debug:

timebook login --debug
