Enhanced Dash MCP Server

🎯 What is this?

This is a Model Context Protocol (MCP) server that augments the official Dash MCP server. The official Dash MCP owns exact Dash-backed operations: installed docsets, precise documentation search, full-text search, and page loading. Enhanced Dash MCP owns the higher-level intelligence around those operations: project context, docset recommendation, local cache discovery, routing, ranking, and workflow guidance.

In simple terms: this server tells Claude and other agentic coding tools which Dash docsets and search_documentation queries to use for the repo and task in front of them. The official Dash MCP still fetches the search results and documentation pages.

📚 About Dash

Dash is an API Documentation Browser and Code Snippet Manager for macOS that gives you instant offline access to 200+ API documentation sets. It's the go-to tool for developers who want fast, searchable, offline documentation without relying on internet connectivity or dealing with slow web searches.

🔗 Why This Integration Matters

• Official Dash Handoff: returns docset identifiers and ready-to-run search_documentation calls when you provide a list_installed_docsets snapshot
• Local Cache Awareness: indexes valid local Dash cache docsets and explains which ones the official Dash MCP cannot see
• Privacy-Focused: project inspection and local cache discovery stay on your machine
• Persistent Metadata Index: stores docset metadata in ~/.cache/dash-mcp/docset-index-v2.json so cold discovery is not repeated unnecessarily
• Context-Aware: detects a repo's stack and suggests relevant Dash docsets automatically

See CHANGELOG.md for version history.

📋 Prerequisites

• macOS with Dash app installed
• Python 3.11+
• Dash docsets downloaded (JavaScript, Python, React, etc.)
• Claude with MCP support
• tmux (recommended for background execution)

⚠️ Important Dependency Requirements

This server requires Pydantic v2.0+ for MCP compatibility. If you have existing projects with Pydantic v1.x, you may need to:

1. Use a virtual environment (recommended)
2. Check for compatibility with other tools (like pieces-os-client)
3. Consider using separate Python environments for different projects

# Check your current Pydantic version
pip show pydantic

# If you have v1.x, you'll need to upgrade
pip install "pydantic>=2.0.0"

📦 Dependencies

The setup script automatically installs all required dependencies, including:

• mcp>=1.9.0 - Model Context Protocol framework
• pydantic>=2.0.0 - Data validation (required for MCP compatibility)
• typing-extensions>=4.12.0 - Extended type hints

⚡ Quick Start

🔄 Important: v2 Boundary Change

If you're upgrading from a previous version, Enhanced Dash MCP no longer exposes direct search/page loading tools. Use the official Dash MCP for:

• list_installed_docsets
• search_documentation
• enable_docset_fts
• load_documentation_page

Use Enhanced Dash MCP for repo-aware recommendations, search planning, ranking, coverage summaries, and missing-docset explanations.

To rebuild the v2 metadata index:

# Clear the metadata index
rm -f ~/.cache/dash-mcp/docset-index-v2.json

# Then restart your server
dash-mcp-restart
# or
cd ~/enhanced-dash-mcp && ./start-dash-mcp.sh --test

What changed: Enhanced Dash MCP now reports local cache docsets only as metadata and fallback diagnostics. It does not fetch documentation pages.

See docs/help.md for a brief overview of how to run the server.

1. Clone & Setup

# Clone or download the project files
mkdir ~/enhanced-dash-mcp && cd ~/enhanced-dash-mcp

# Make setup script executable
chmod +x scripts/setup-dash-mcp.sh

# Run automated setup
./scripts/setup-dash-mcp.sh

The script prompts for an installation directory. Press Enter to accept the default path or provide a custom location. The default is ~/enhanced-dash-mcp.

2. Configure Claude

Add this to Claude's MCP settings:

{
  "mcpServers": {
    "enhanced-dash-mcp": {
      "command": "$DASH_MCP_DIR/venv/bin/python3",
      "args": [
        "$DASH_MCP_DIR/enhanced_dash_server.py"
      ],
      "env": {}
    }
  }
}

3. Start & Test

# Add shell enhancements
echo "source ~/enhanced-dash-mcp/dash-mcp-aliases.sh" >> ~/.zshrc
source ~/.zshrc

# Start the server
dash-mcp-start

🤖 Automation & Non-Interactive Operation

The Enhanced Dash MCP server features comprehensive automation detection and non-interactive operation capabilities, making it suitable for CI/CD pipelines, deployment scripts, and containerized environments.

🔍 Interactive Mode Detection Logic

The server uses an 8-phase detection sequence to determine whether it's running in interactive or automated mode:

Phase 1: CI Environment Detection

Checks for continuous integration indicators:

# Primary CI Variables
CI, CONTINUOUS_INTEGRATION, GITHUB_ACTIONS, GITLAB_CI, JENKINS_URL
TRAVIS, CIRCLECI, BUILDKITE, DRONE, BITBUCKET_BUILD_NUMBER
AZURE_HTTP_USER_AGENT, CODEBUILD_BUILD_ID, TEAMCITY_VERSION
# And 15+ more CI environment variables

Phase 2: Automation Environment Detection

Identifies automated/batch processing:

# Automation Indicators
AUTOMATION, AUTOMATED, NON_INTERACTIVE, BATCH_MODE, HEADLESS
CRON, SYSTEMD_EXEC_PID, KUBERNETES_SERVICE_HOST, DOCKER_CONTAINER
AWS_EXECUTION_ENV, LAMBDA_RUNTIME_DIR, GOOGLE_CLOUD_PROJECT
# Cloud platforms: Heroku, Vercel, Netlify, Railway, etc.

Phase 3-8: Terminal & Process Environment

• Terminal Type: Validates TERM environment (rejects dumb, unknown)
• Shell Capabilities: Checks for interactive shell support
• TTY Stream Detection: Verifies STDIN/STDOUT/STDERR are connected to terminals
• Process Environment: Detects daemon processes, nohup, orphaned processes
• SSH Connections: Validates TTY allocation in remote connections
• Session Management: Recognizes tmux/screen sessions

🏗️ Architecture

Core Components

• DashMCPServer - Internal local-cache metadata indexer
• DashAugmentationServer - Project-aware recommendation and handoff planner
• OfficialDocsetIndex - Optional official Dash snapshot matcher
• ProjectDocsContext - Repo context model for languages, frameworks, dependencies, and manifests

Data Flow

1. Task or repo path received from Claude via MCP
2. Project context analyzed from manifests and source files
3. Relevant docsets identified and matched against the optional official snapshot
4. Official Dash search plans generated with identifiers when available
5. Local-only cache gaps explained only when official Dash cannot see the docset
6. Handoff envelope returned for the caller to run official Dash MCP operations

Caching Strategy

• Persistent Metadata Index - Stores local docset metadata, not page content
• Mtime Invalidation - Rebuilds when the Dash root, Info.plist, or docSet.dsidx changes
• Force Refresh - Recommendation and coverage tools accept force_refresh=true

📊 Performance

Benchmarks

• First metadata index: depends on Dash cache size and docset count
• Cached metadata reads: fast JSON load from docset-index-v2.json
• Official search/page loading: handled by the official Dash MCP, not this server

Optimization Tips

• Keep server running in tmux for best performance
• Pass an official Dash docset snapshot when you need exact identifiers
• Use force_refresh=false for routine recommendations
• Use force_refresh=true only after installing or moving docsets

🔍 Available Tools

🚨 Troubleshooting

Common Issues

❌ "No docsets found"

# Ensure Dash is installed with docsets
ls ~/Library/Application\ Support/Dash/DocSets/
# Should show *.docset directories
# Optionally set DASH_DOCSETS_PATH if your docsets live elsewhere
# (symlinks to the default location are supported)
# When creating a symlink, point it at `~/Library/Application Support/Dash`.
# A symlink directly to the `DocSets` folder will produce a search path
# ending in `DocSets/DocSets` and no docsets will be discovered.
# The server now resolves such symlinks automatically and also corrects
# `DASH_DOCSETS_PATH` values that point at the parent `Dash` directory.

❌ "Permission errors"

# Check Python environment
python --version
source ~/enhanced-dash-mcp/venv/bin/activate

❌ "Import errors"

# Reinstall dependencies
cd ~/enhanced-dash-mcp
source venv/bin/activate
pip install -r requirements.txt

❌ "Server won't start"

# Check if port is in use
tmux kill-session -t dash-mcp
dash-mcp-start

❌ "Slow searches"

# First searches build cache - subsequent searches are much faster
# Check cache directory
ls ~/.cache/dash-mcp/
