Which integrations are available for this server?

Provides tools for interacting with Phabricator's Conduit API, enabling management of tasks, code reviews, repositories, users, projects, pastes, wiki documents, blogs, and more.

How do I use phabricator-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@phabricator-mcp list my recent revisions" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

phabricator-mcp

An MCP (Model Context Protocol) server that wraps Phabricator's Conduit API, enabling any MCP client to interact with Phabricator tasks, code reviews, repositories, and more.

Star History

Installation

Claude Code (CLI)

claude mcp add --scope user phabricator -- npx @freelancercom/phabricator-mcp@latest

Or with environment variables (if not using ~/.arcrc):

claude mcp add --scope user phabricator \
  -e PHABRICATOR_URL=https://phabricator.example.com \
  -e PHABRICATOR_API_TOKEN=api-xxxxx \
  -- npx @freelancercom/phabricator-mcp@latest

The --scope user flag installs the server globally, making it available in all projects.

Codex (OpenAI CLI)

Add to your Codex config (~/.codex/config.json):

{
  "mcpServers": {
    "phabricator": {
      "command": "npx",
      "args": ["@freelancercom/phabricator-mcp@latest"],
      "env": {
        "PHABRICATOR_URL": "https://phabricator.example.com",
        "PHABRICATOR_API_TOKEN": "api-xxxxxxxxxxxxx"
      }
    }
  }
}

opencode

Add to your opencode config (~/.config/opencode/config.json):

{
  "mcp": {
    "servers": {
      "phabricator": {
        "command": "npx",
        "args": ["@freelancercom/phabricator-mcp@latest"],
        "env": {
          "PHABRICATOR_URL": "https://phabricator.example.com",
          "PHABRICATOR_API_TOKEN": "api-xxxxxxxxxxxxx"
        }
      }
    }
  }
}

VS Code with Claude Extension

Add to your VS Code settings.json:

{
  "claude.mcpServers": {
    "phabricator": {
      "command": "npx",
      "args": ["@freelancercom/phabricator-mcp@latest"],
      "env": {
        "PHABRICATOR_URL": "https://phabricator.example.com",
        "PHABRICATOR_API_TOKEN": "api-xxxxxxxxxxxxx"
      }
    }
  }
}

Cursor

Add to your Cursor MCP config (~/.cursor/mcp.json):

{
  "mcpServers": {
    "phabricator": {
      "command": "npx",
      "args": ["@freelancercom/phabricator-mcp@latest"],
      "env": {
        "PHABRICATOR_URL": "https://phabricator.example.com",
        "PHABRICATOR_API_TOKEN": "api-xxxxxxxxxxxxx"
      }
    }
  }
}

GitHub Copilot (VS Code)

Add to your VS Code settings.json:

{
  "github.copilot.chat.mcp.servers": {
    "phabricator": {
      "command": "npx",
      "args": ["@freelancercom/phabricator-mcp@latest"],
      "env": {
        "PHABRICATOR_URL": "https://phabricator.example.com",
        "PHABRICATOR_API_TOKEN": "api-xxxxxxxxxxxxx"
      }
    }
  }
}

Upgrading

The default install uses @freelancercom/phabricator-mcp@latest, which tells npx to check for updates on each run. No action needed.

If you pinned a specific version (e.g. @freelancercom/phabricator-mcp@1.0.0) or omitted the version suffix, npx caches the package and won't pick up new versions. To upgrade:

npx clear-npx-cache

Then restart your MCP client.

Migrating from `github:freelancer/phabricator-mcp`

If you previously installed using the GitHub URL, update your config to use the npm package instead:

# Remove old server
claude mcp remove phabricator -s user

# Add new one
claude mcp add --scope user phabricator -- npx @freelancercom/phabricator-mcp@latest

For JSON configs, replace ["github:freelancer/phabricator-mcp"] with ["@freelancercom/phabricator-mcp@latest"] in your args.

Configuration

The server automatically reads configuration from ~/.arcrc (created by Arcanist). No additional configuration is needed if you've already set up arc.

Alternatively, set environment variables (which take precedence over .arcrc):

PHABRICATOR_URL - Phabricator instance URL
PHABRICATOR_API_TOKEN - Conduit API token

You can get an API token from your Phabricator instance at: Settings > Conduit API Tokens

Recommended: Allow Read-Only Tool Permissions

By default, Claude Code will prompt you for permission each time a Phabricator tool is called. It's recommended to allowlist the read-only tools so they run without prompts, while keeping write operations (create, edit, comment) behind a confirmation step.

Add to your ~/.claude/settings.json:

{
  "permissions": {
    "allow": [
      "mcp__phabricator__phabricator_task_search",
      "mcp__phabricator__phabricator_task_status_search",
      "mcp__phabricator__phabricator_task_priority_search",
      "mcp__phabricator__phabricator_revision_search",
      "mcp__phabricator__phabricator_diff_search",
      "mcp__phabricator__phabricator_diff_raw",

      "mcp__phabricator__phabricator_blog_search",
      "mcp__phabricator__phabricator_blog_post_search",
      "mcp__phabricator__phabricator_file_search",
      "mcp__phabricator__phabricator_file_info",
      "mcp__phabricator__phabricator_buildable_search",
      "mcp__phabricator__phabricator_build_search",
      "mcp__phabricator__phabricator_build_target_search",
      "mcp__phabricator__phabricator_build_log_search",
      "mcp__phabricator__phabricator_build_plan_search",
      "mcp__phabricator__phabricator_owners_search",
      "mcp__phabricator__phabricator_feed_query",
      "mcp__phabricator__phabricator_conpherence_search",
      "mcp__phabricator__phabricator_conpherence_read",
      "mcp__phabricator__phabricator_audit_query",
      "mcp__phabricator__phabricator_phid_lookup",
      "mcp__phabricator__phabricator_phid_query",
      "mcp__phabricator__phabricator_transaction_search",
      "mcp__phabricator__phabricator_version"
    ]
  }
}

To allowlist all tools including write operations, use "mcp__phabricator__*" instead.
