mcp-tap 0.5.3

The last MCP server you install by hand. Discover, install, and configure MCP servers from inside your AI assistant.

mcp-tap

The last MCP server you install by hand.

mcp-tap lives inside your AI assistant. Ask it to find, install, and configure any MCP server — by talking to it. No more editing JSON files. No more Googling environment variables. No more "why won't this connect?"

"Find me an MCP for PostgreSQL."

That's it. mcp-tap searches the registry, installs the package, generates the config, validates the connection — all through conversation.

Before mcp-tap

1. Google "MCP server for postgres"
2. Find 4 competing packages, compare stars and last commit dates
3. Pick one, read the README
4. Figure out the right command, args, and env values
5. Manually edit claude_desktop_config.json (or mcp.json, or mcp_config.json...)
6. Realize you need a POSTGRES_CONNECTION_STRING environment variable
7. Find your connection string, add it to the config, restart the client
8. Get "connection refused", debug for 20 minutes
9. Finally works. Repeat for every server. Repeat for every client.

After mcp-tap

You: "Set up MCP servers for my project."

mcp-tap: I scanned your project and found:
  - PostgreSQL (from docker-compose.yml)
  - Slack (SLACK_BOT_TOKEN in your .env)
  - GitHub (detected .github/ directory)

  I recommend 3 servers. Want me to install them?

You: "Yes, all of them."

mcp-tap: Done. All connections verified. 35 new tools available.

Install

You install mcp-tap once. It installs everything else.

Claude Desktop

Add to your claude_desktop_config.json:

With uvx (recommended):

{
  "mcpServers": {
    "mcp-tap": {
      "command": "uvx",
      "args": ["mcp-tap"]
    }
  }
}

With npx:

{
  "mcpServers": {
    "mcp-tap": {
      "command": "npx",
      "args": ["-y", "mcp-tap"]
    }
  }
}

Claude Code

# With uvx (recommended)
claude mcp add mcp-tap -- uvx mcp-tap

# With npx
claude mcp add mcp-tap -- npx -y mcp-tap

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "mcp-tap": {
      "command": "uvx",
      "args": ["mcp-tap"]
    }
  }
}

Or use npx — replace "command": "uvx", "args": ["mcp-tap"] with "command": "npx", "args": ["-y", "mcp-tap"].

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "mcp-tap": {
      "command": "uvx",
      "args": ["mcp-tap"]
    }
  }
}

Or use npx — replace "command": "uvx", "args": ["mcp-tap"] with "command": "npx", "args": ["-y", "mcp-tap"].

What can it do?

You say	mcp-tap does
"Scan my project and recommend MCP servers"	Detects your tech stack, shows what's missing
"Find me an MCP for PostgreSQL"	Searches the registry, compares options
"Set up the official postgres server"	Installs, configures, validates the connection
"Set it up on all my clients"	Configures Claude Desktop, Cursor, and Windsurf at once
"What MCP servers do I have?"	Lists all configured servers across clients
"Are my MCP servers working?"	Health-checks every server concurrently
"Test my postgres connection"	Spawns the server, connects, lists available tools
"Remove the slack MCP"	Removes from config cleanly

Tools

Tool	What it does
scan_project	Scans your project directory — detects languages, frameworks, databases, CI/CD pipelines — and recommends MCP servers
search_servers	Searches the MCP Registry by keyword, with maturity scoring and project relevance ranking
configure_server	Installs a package (npm/pip/docker), runs a security gate, validates the connection, and writes config
test_connection	Spawns a server process, connects via MCP protocol, and lists its tools. Auto-heals on failure
check_health	Tests all configured servers concurrently, detects tool conflicts between servers
inspect_server	Fetches a server's README and extracts configuration hints
list_installed	Shows all configured servers with secrets masked (layered detection: key names, prefixes, high-entropy)
remove_server	Removes a server from one or all client configs
verify	Compares mcp-tap.lock against actual config — detects drift
restore	Recreates server configs from a lockfile (like npm ci for MCP)
apply_stack	Installs a group of servers from a shareable stack profile

Plus automatic lockfile management on every configure/remove.

Features

• Project-aware: Scans your codebase — including CI/CD configs (GitHub Actions, GitLab CI) — to recommend servers based on your actual stack
• Security gate: Blocks suspicious install commands, archived repos, and known-risky patterns before installing
• Lockfile: mcp-tap.lock tracks exact versions and hashes of all your MCP servers. Reproducible setups across machines
• Stacks: Shareable server profiles — install a complete Data Science, Web Dev, or DevOps stack in one command
• Multi-client: Configure Claude Desktop, Claude Code, Cursor, and Windsurf — all at once or individually
• Auto-healing: Failed connections are automatically diagnosed and fixed when possible
• Tool conflict detection: Warns when two servers expose overlapping tools that could confuse the LLM
• Connection validation: Every install is verified with a real MCP connection test
• Secrets masked: list_installed never exposes environment variable values

Requirements

• Python 3.11+ with uv (recommended), or
• Node.js 18+ (the npm package is a thin wrapper that calls the Python package via uvx/pipx)
