Add one entry to Claude Code, Cursor, Windsurf, or any MCP-compatible tool and instantly gain access to your entire MCP ecosystem.\n\nKey differentiators:\n- **Single configuration, universal access** — Define servers once, use everywhere\n- **Namespace profiles** — Group servers by context (work, personal, project) with per-namespace tool permissions\n- **Multi-transport** — Manage both local stdio processes and remote HTTP/SSE endpoints\n- **Registry browser** — Search the official MCP registry and install servers with pre-populated config\n- **Interactive TUI** — Monitor, test, and manage servers with a terminal interface\n- **Tool permissions** — Block unused tools per-namespace or globally deny dangerous tools at the server level\n- **Defense-in-depth** — Server-level global deny list that overrides all namespace permissions\n- **Resource \u0026 prompt passthrough** — Optionally expose upstream resources and prompts via `--resources` and `--prompts` flags\n\n\n### TUI\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"360\" alt=\"image\" src=\"https://github.com/user-attachments/assets/481cebb2-c3de-4c4b-8b01-81f43ab06c54\" /\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"359\" alt=\"image\" src=\"https://github.com/user-attachments/assets/127f1ccd-4882-4676-876a-4f7cb067769e\" /\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"359\" alt=\"image\" src=\"https://github.com/user-attachments/assets/9378dff4-14b1-49a1-bfe6-4c5a00d73bfc\" /\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg width=\"466\" height=\"358\" alt=\"image\" src=\"https://github.com/user-attachments/assets/763e8be4-e84c-45c9-9795-792769be7504\" /\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n### Web\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"313\" alt=\"Web UI servers\" src=\"https://github.com/user-attachments/assets/6a9d7ea3-29db-4ab9-b14f-21524e05ded1\" /\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"313\" alt=\"Web UI server detail\" src=\"https://github.com/user-attachments/assets/7ec8f3b1-7bab-4433-a21d-9b720baaf737\" /\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"313\" alt=\"Web UI namespaces\" src=\"https://github.com/user-attachments/assets/a3b1a8eb-be48-47cc-8fe8-eaa37a22e9d8\" /\u003e\u003c/td\u003e\n    \u003ctd\u003e\u003cimg width=\"467\" height=\"313\" alt=\"Web UI registry\" src=\"https://github.com/user-attachments/assets/e62457c7-70a1-4674-9640-1e6c0136f53d\" /\u003e\u003c/td\u003e\n  \u003c/tr\u003e\n\u003c/table\u003e\n\n## Installation\n\n### Homebrew (macOS/Linux)\n\n```bash\nbrew tap Bigsy/tap\nbrew install mcpmu\n```\n\n### From source\n\n```bash\ngo install github.com/Bigsy/mcpmu/cmd/mcpmu@latest\n```\n\n## Quick Start\n\n### Let your agent set it up\n\nInstall the mcpmu skill, then ask your coding agent to do the rest — it can read your existing MCP config, import your servers into mcpmu, and register mcpmu as your single MCP endpoint:\n\n```bash\nmcpmu skill install\n```\n\nThen tell your agent: *\"Read my current MCP config, add all my servers to mcpmu, and register mcpmu as an MCP server\"*\n\n### Or set it up manually with via the TUI, Web or Cmdline\n\n**1. Add your MCP servers:**\n\n```bash\n# Start TUI\nmcpmu\n\n# Start web\nmcpmu web\n\n#Or just use the cli\n\n# Add a stdio server\nmcpmu add context7 -- npx -y @upstash/context7-mcp\n\n# Add an HTTP server\nmcpmu add atlassian https://mcp.atlassian.com/mcp --scopes read,write\n```\n\n**2. Register mcpmu with your agent:**\n\n```bash\n# Claude Code\nclaude mcp add mcpmu -- mcpmu serve --stdio\n\n# Codex\ncodex mcp add mcpmu -- mcpmu serve --stdio\n```\n\nOr add directly to any MCP config JSON (Claude Code, Cursor, Windsurf, etc.):\n```json\n{\n  \"mcpmu\": {\n    \"command\": \"mcpmu\",\n    \"args\": [\"serve\", \"--stdio\"]\n  }\n}\n```\n\nThat's it. Your agent now has access to all your configured MCP servers through a single endpoint.\n\n## Namespaces\n\nNamespaces let you create different server profiles — one for work, one for personal projects, a minimal one for keeping context length down.\n\n```bash\n# Create namespaces\nmcpmu namespace add work --description \"Work servers\"\nmcpmu namespace add personal --description \"Personal projects\"\n\n# Assign servers to namespaces\nmcpmu namespace assign work atlassian\nmcpmu namespace assign work context7\nmcpmu namespace assign personal context7\n```\n\nThen point each agent at the namespace it needs:\n\n**Claude Code:**\n```bash\nclaude mcp add work -- mcpmu serve --stdio --namespace work\n```\n\n**Codex:**\n```bash\ncodex mcp add personal -- mcpmu serve --stdio --namespace personal\n```\n\nIf no namespace is specified, mcpmu uses the default namespace (usually the first namespace created).\n\n## Tool Permissions\n\nControl which tools are exposed per namespace — useful for keeping context lean or restricting access. Can also be all configured from the TUI (probably easier there):\n\n```bash\n# Allow/deny specific tools\nmcpmu permission set work atlassian jira_search allow\nmcpmu permission set work atlassian confluence_delete deny\n\n# Deny all tools by default, then allowlist what you need\nmcpmu namespace set-deny-default minimal true\nmcpmu permission set minimal context7 resolve allow\n\n# Per-server deny-default — deny a tool-heavy server, allow the rest\nmcpmu permission set-server-default work grafana deny\nmcpmu permission set work grafana query_loki_logs allow\n```\n\n### Server-level global deny\n\nFor defense-in-depth, you can deny tools at the server level. Globally denied tools are blocked regardless of namespace permissions — even a namespace explicit allow cannot override a server global deny:\n\n```bash\nmcpmu server deny-tool filesystem delete_file move_file\nmcpmu server allow-tool filesystem move_file   # re-enable\nmcpmu server denied-tools filesystem           # list denied tools\n```\n\nPermission resolution order: **server global deny \u003e explicit tool permission \u003e server default \u003e namespace default \u003e allow**.\n\nA common pattern: keep a lean namespace with only your most-used tools for everyday work, and an \"extra\" namespace with the full suite that you add as a second MCP server when needed.\n\n## Features\n\n- **Stdio process management** — Spawn and supervise local MCP servers (npx, binaries, scripts)\n- **Streamable HTTP/SSE** — Connect to remote MCP endpoints with full SSE support\n- **MCP aggregation** — Expose all managed servers as a single MCP endpoint via `mcpmu serve --stdio`\n- **OAuth support** — Full OAuth 2.1 with PKCE, dynamic client registration, token management, and automatic scope discovery\n- **Hot-reload** — Serve mode watches the config file and automatically applies changes without restart\n- **Lazy or eager startup** — Start servers on-demand or pre-start everything with `--eager`\n- **Registry browser** — Search the official MCP server registry from the TUI and install with pre-populated config (`a` → Official Registry)\n- **Interactive TUI** — Real-time logs, server status, start/stop controls, and namespace switching\n- **Web UI** — Browser-based management via `mcpmu web` with live log streaming, CRUD operations, and registry browser\n\n## Serve Mode\n\nExpose managed servers as a single MCP endpoint:\n\n```bash\nmcpmu serve --stdio                          # default namespace\nmcpmu serve --stdio --namespace work         # specific namespace\nmcpmu serve --stdio -n work --eager          # pre-start all servers\nmcpmu serve --stdio --expose-manager-tools   # include mcpmu.* management tools\nmcpmu serve --stdio --log-level debug        # verbose logging\n```\n\n## Shell Completions\n\nTab-completion for server names, namespace names, and subcommand arguments. If installed via Homebrew:\n\n```bash\nmcpmu completion zsh \u003e \"$(brew --prefix)/share/zsh/site-functions/_mcpmu\"\n```\n\nFor bash, fish, and PowerShell setup see [docs/completions.md](docs/completions.md).\n\n## Full CLI Reference\n\nFor the complete list of commands, flags, config schema, and HTTP server fields see [docs/CLI.md](docs/CLI.md).\n\n## Agent Skill\n\nmcpmu ships with a built-in [agent skill](https://agentskills.io) that teaches AI coding agents how to use the mcpmu CLI. Install it with a single command:\n\n```bash\nmcpmu skill install\n```\n\nThis auto-detects which agents you have installed and copies the skill to the right locations:\n\n| Agent | Path |\n|-------|------|\n| Claude Code | `~/.claude/skills/mcpmu/SKILL.md` |\n| Codex CLI | `~/.codex/skills/mcpmu/SKILL.md` |\n| Cross-agent | `~/.agents/skills/mcpmu/SKILL.md` |\n\nThe cross-agent path (`~/.agents/`) is always created as it's the emerging standard.\n\nTo remove the skill from all locations:\n\n```bash\nmcpmu skill uninstall\n```\n\nOnce installed, your agent will automatically know how to use mcpmu commands when you ask about MCP server management.\n\n## Building from source\n\n```bash\ngit clone https://github.com/Bigsy/mcpmu.git\ncd mcpmu\ngo build -o mcpmu ./cmd/mcpmu\n./mcpmu\n```\n\n## Testing\n\n```bash\ngo test ./...\nmake check            # lint + tests\nmake test-integration # integration tests\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbigsy%2Fmcpmu","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbigsy%2Fmcpmu","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbigsy%2Fmcpmu/lists"}
