MCP Servers

The package manager for MCP servers. Discover · install · update · audit — all from one CLI.

npx ccmcp install slack

🛒 The MCP problem

There are hundreds of MCP servers. They're scattered across:

• GitHub (search "mcp-server-*")
• npm (@modelcontextprotocol/*)
• PyPI (mcp-*)
• GoLang modules
• Random blog posts and tweets

Installing one means:

1. Find the repo
2. Read the install instructions (usually wrong)
3. Manually edit settings.json
4. Hope you got the JSON right
5. Restart Claude Code
6. Pray

ccmcp (claude-code-mcp) fixes this. One CLI. Curated registry. Verified servers.

⚡ Commands

# Search
ccmcp search slack
ccmcp search "database"

# Install
ccmcp install slack
ccmcp install slack --scope project   # vs --scope user

# List installed
ccmcp list

# Update
ccmcp update slack
ccmcp update --all

# Remove
ccmcp uninstall slack

# Audit installed servers (security + freshness check)
ccmcp audit

The CLI:

• ✅ Validates the server's manifest
• ✅ Checks for known CVEs in its dependencies
• ✅ Tests it boots successfully before saving
• ✅ Edits your settings.json with proper backup
• ✅ Restarts Claude Code if needed (optional)

🛡️ Security

Every server in the registry has been manually reviewed for:

• ✅ Source available on GitHub
• ✅ No obfuscated code
• ✅ Permissions clearly documented
• ✅ Maintained (commits within last 6 months)
• ✅ No known critical CVEs in dependencies

We classify each server by trust tier:

| Tier | Meaning | |------|---------| | 🟢 Official | Maintained by the service vendor (Slack, GitHub, etc.) | | 🔵 Verified | Maintained by trusted community contributor, code-reviewed | | 🟡 Community | Community-maintained, less rigorous review | | 🔴 Experimental | Use at own risk |

ccmcp install shows the tier before installing, and you can configure a minimum:

ccmcp config set min_trust_tier verified

📂 Server Manifest

Every registered server includes a mcp.toml:

name = "slack"
version = "2.1.0"
description = "Send messages, read channels, manage Slack workspaces."
author = "Slack, Inc."
license = "MIT"
trust_tier = "official"

[install]
type = "npm"                  # npm | pip | go | docker | binary
package = "@slack/mcp-server"
binary_name = "mcp-server-slack"

[runtime]
command = "mcp-server-slack"
env_required = ["SLACK_BOT_TOKEN"]
env_optional = ["SLACK_USER_TOKEN"]

[capabilities]
tools = ["send_message", "read_channel", "list_channels", "react_message"]
resources = ["channels", "users", "files"]

[permissions]
network = ["api.slack.com"]
filesystem = false
shell = false

This lets ccmcp show you exactly what permissions a server wants before you install.

🤝 Contributing a server

ccmcp submit ./my-mcp-server

This runs the manifest validator + a smoke test + opens a PR against the registry. Approved within 7 days if the manifest is complete.
