keeping-mcp

Open-source Model Context Protocol (MCP) server that exposes the Keeping (api.keeping.nl) time-tracking API as tools an AI coding assistant can call. Built for solo developers who use Claude Code (or any MCP-capable client) and want their billable hours logged into Keeping at the end of a session instead of typed in by hand, while keeping Keeping's existing native Jortt invoicing integration intact. Every write tool is dry-run by default — your hours never reach Keeping until you explicitly confirm.

⚠ Writes are dry-run BY DEFAULT

Every write tool (keeping_add_entry, keeping_update_entry, keeping_delete_entry, keeping_start_timer, keeping_stop_timer, keeping_resume_timer) returns a preview unless you pass confirm: true in the tool call.

Setting KEEPING_REQUIRE_CONFIRM=false in your environment disables this gate. Writes then happen on the first call — there is no second chance.

Recommendation: never disable this gate unless you are running the server in a non-interactive automation context and have explicitly accepted the loss of the confirmation step.

Install

Claude Code on Windows 11

Add to %APPDATA%\Claude\claude_desktop_config.json or to your project's .mcp.json file.

{
  "mcpServers": {
    "keeping-mcp": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "keeping-mcp"],
      "env": {
        "KEEPING_TOKEN": "kp_live_your_token_here"
      }
    }
  }
}

The cmd /c wrapper is required on Windows — npx resolves to npx.cmd, and Claude Code's process spawn does not search PATHEXT extensions (see anthropics/claude-code#58510).

Claude Code on macOS / Linux

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or ~/.config/Claude/claude_desktop_config.json (Linux), or your project's .mcp.json.

{
  "mcpServers": {
    "keeping-mcp": {
      "command": "npx",
      "args": ["-y", "keeping-mcp"],
      "env": {
        "KEEPING_TOKEN": "kp_live_your_token_here"
      }
    }
  }
}

Other MCP clients

Any MCP-capable client that supports the stdio transport works. The server is started by npx -y keeping-mcp and reads KEEPING_TOKEN from its environment. Discoverable in the MCP Registry as io.github.Red-Square-Software/keeping-mcp.

Get a Keeping access token

1. Sign in to your Keeping account.
2. Open Preferences (top-right menu).
3. Find the section Show features for developers and enable it.
4. A new Personal access tokens section appears.
5. Click Generate new token, name it (e.g. "Claude Code"), and copy the value.
6. Store it as KEEPING_TOKEN in your shell environment OR in your Claude Code config env block.

The token has full read+write access to your time entries — treat it like a password. Never commit it to git, never paste it into a chat, never read it back from a tool response (keeping-mcp never echoes it).

Configuration

| Variable | Required | Default | Purpose | |----------|----------|---------|---------| | KEEPING_TOKEN | yes | — | Keeping personal access token (created via the section above). | | KEEPING_REQUIRE_CONFIRM | no | true | When true, write tools return a preview unless called with confirm: true. Setting to false disables the gate entirely — see warning below. | | KEEPING_ORG_ID | no | — | Pin all calls to one organisation id. When unset and the token has access to multiple orgs, write tools require explicit organisation_id input per call. | | KEEPING_LOG_LEVEL | no | info | Server stderr log verbosity. Accepts: debug, info, warn, error. |

⚠ Writes are dry-run BY DEFAULT

Every write tool (keeping_add_entry, keeping_update_entry, keeping_delete_entry, keeping_start_timer, keeping_stop_timer, keeping_resume_timer) returns a preview unless you pass confirm: true in the tool call.

Recommendation: never disable this gate unless you are running the server in a non-interactive automation context and have explicitly accepted the loss of the confirmation step.

Tools

keeping-mcp registers 12 tools when the server starts. Read tools (keeping_me, keeping_organisations, keeping_projects, keeping_tasks, keeping_list_entries, keeping_timer_status) call Keeping's API without confirmation. Write tools (keeping_add_entry, keeping_update_entry, keeping_delete_entry, keeping_start_timer, keeping_stop_timer, keeping_resume_timer) return a dry-run preview unless invoked with confirm: true (default behavior controlled by KEEPING_REQUIRE_CONFIRM).

Dry-run workflow (example transcript)

Write tools follow a two-step pattern: propose-then-confirm. The first call returns a preview of the HTTP request the server would send; the second call (with confirm: true) actually sends it.

Step 1 — preview (no confirm, no API call made). Illustrative; actual field names match Keeping's OpenAPI (see https://developer.keeping.nl).

{
  "tool": "keeping_add_entry",
  "input": {
    "description": "Phase 4 release prep",
    "hours": 1.5,
    "project_id": 123
  },
  "response": {
    "would_post": {
      "method": "POST",
      "url": "/v1/organisations/456/time_entries",
      "body": {
        "description": "Phase 4 release prep",
        "hours": 1.5,
        "project_id": 123,
        "date": "2026-06-12",
        "purpose": "work"
      }
    }
  }
}

Step 2 — confirm (confirm: true added, request is sent to Keeping). Illustrative; actual response shape mirrors Keeping's OpenAPI.

{
  "tool": "keeping_add_entry",
  "input": {
    "description": "Phase 4 release prep",
    "hours": 1.5,
    "project_id": 123,
    "confirm": true
  },
  "response": {
    "id": 98765,
    "day": "2026-06-12",
    "hours": 1.5,
    "description": "Phase 4 release prep",
    "project_id": 123,
    "purpose": "work"
  }
}

Verifying provenance

Releases are published via GitHub Actions OIDC trusted publishing (no long-lived npm tokens). Every release carries an npm provenance attestation linking the published tarball to a specific commit in this repository.

npm audit signatures
# or, for a single package:
npm view keeping-mcp --json | jq '.dist.attestations'

Local development

git clone https://github.com/red-square-software/keeping-mcp.git
cd keeping-mcp
npm ci
npm test
npm run build
KEEPING_TOKEN=kp_live_your_token_here node dist/bin/keeping-mcp.js

All server output goes to stderr — stdout is reserved for MCP JSON-RPC framing. Never write diagnostic output to stdout; use console.error for logging.
