upwork-mcp

An MCP server for Upwork automation. Search jobs, draft and submit proposals, manage messages and contracts — all from Claude Desktop or any MCP-compatible client.

Features

• Job Search — keyword search with filters (budget, hourly rate, experience level, client rating, recency), automatic scoring and red-flag detection

• Proposal Workflow — draft from templates, preview, then submit with explicit confirmation; daily limit enforced

• Client Vetting — 7-condition red-flag checker (payment verification, rating, hire history, account age, repost count, proposal volume, hourly rate floor)

• Messages — list unread conversations, read threads, draft and send replies

• Contracts — list active/past contracts, view details and work diary entries

• Session Safety — persistent Chromium profile, Cloudflare detection, 7-day idle expiry, domain restriction to upwork.com

• Audit Log — every tool call appended to ~/.upwork-mcp/audit.log (metadata only, no content)

Requirements

• Python 3.11+

• uv (recommended) or pip

• A valid Upwork account

Installation

Using uv (recommended)

git clone https://github.com/kubegrind/upwork-mcp
cd upwork-mcp
uv sync
uv run playwright install chromium

Using pip

git clone https://github.com/kubegrind/upwork-mcp
cd upwork-mcp
pip install -e .
playwright install chromium

Configuration

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "upwork": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/upwork-mcp",
        "run",
        "upwork-mcp"
      ]
    }
  }
}

Claude Code

claude mcp add upwork -- uv --directory /absolute/path/to/upwork-mcp run upwork-mcp

Environment Variables

Authentication

The server uses a persistent Chromium browser profile. On first run, authenticate manually:

uv run upwork-mcp --no-headless

A browser window will open. Log in to Upwork normally. The session is saved to ~/.upwork-mcp/profile/ and reused on subsequent runs. Sessions expire after 7 days of inactivity.

Proposal Templates

Templates live in ~/.upwork-mcp/templates/. The default template is loaded from default.txt if it exists. Pass a filename via template_name to use a custom template.

Supported variables:

{job_title}         {client_name}       {key_skill}
{estimated_timeline} {rate}             {years_experience}
{industries}        {custom_paragraph}  {start_date}
{your_name}

Example template (~/.upwork-mcp/templates/default.txt):

Hi {client_name},

I noticed you're looking for {key_skill} help on {job_title}.
I have {years_experience} years of relevant experience and can deliver {estimated_timeline}.

My rate is {rate}.

{your_name}

Saved Searches

Create JSON files in ~/.upwork-mcp/searches/ to save search configurations:

{
  "query": "devops kubernetes",
  "experience_level": "expert",
  "budget_min": 500,
  "client_rating_min": 4.5
}

Run with upwork_run_saved_search(search_name="devops").

Job Scoring

Jobs are scored 1–10 using a weighted model:

Jobs scoring below 4.0 are filtered from results. Jobs scoring 7.0 or above are marked [HIGH PRIORITY].

Safety

• WRITE tools (submit_proposal, withdraw_proposal, send_message, close_session, rotate_session) require confirmed: true — the model cannot act without explicit user confirmation

• Daily proposal limit — hard block at 10 submissions per day

• Domain restriction — browser navigation is restricted to upwork.com

• No credential exposure — cookies and tokens are never returned, logged, or printed

• Path traversal protection — template and saved search filenames are validated with Path.is_relative_to()

• Audit log — all tool calls recorded with timestamp, action type, target, and status
