1	# ⚡️ mcpo
2
3	Expose any MCP tool as an OpenAPI-compatible HTTP server—instantly.
4
5	mcpo is a dead-simple proxy that takes an MCP server command and makes it accessible via standard RESTful OpenAPI, so your tools "just work" with LLM agents and apps expecting OpenAPI servers.
6
7	No custom protocol. No glue code. No hassle.
8
9	## 🤔 Why Use mcpo Instead of Native MCP?
10
11	MCP servers usually speak over raw stdio, which is:
12
13	- 🔓 Inherently insecure
14	- ❌ Incompatible with most tools
15	- 🧩 Missing standard features like docs, auth, error handling, etc.
16
17	mcpo solves all of that—without extra effort:
18
19	- ✅ Works instantly with OpenAPI tools, SDKs, and UIs
20	- 🛡 Adds security, stability, and scalability using trusted web standards
21	- 🧠 Auto-generates interactive docs for every tool, no config needed
22	- 🔌 Uses pure HTTP—no sockets, no glue code, no surprises
23
24	What feels like "one more step" is really fewer steps with better outcomes.
25
26	mcpo makes your AI tools usable, secure, and interoperable—right now, with zero hassle.
27
28	## 🚀 Quick Usage
29
30	We recommend using uv for lightning-fast startup and zero config.
31
32	```bash
33	uvx mcpo --port 8000 --api-key "top-secret" -- your_mcp_server_command
34	```
35
36	Or, if you’re using Python:
37
38	```bash
39	pip install mcpo
40	mcpo --port 8000 --api-key "top-secret" -- your_mcp_server_command
41	```
42
43	To use an SSE-compatible MCP server, simply specify the server type and endpoint:
44
45	```bash
46	mcpo --port 8000 --api-key "top-secret" --server-type "sse" -- http://127.0.0.1:8001/sse
47	```
48
49	You can also provide headers for the SSE connection:
50
51	```bash
52	mcpo --port 8000 --api-key "top-secret" --server-type "sse" --header '{"Authorization": "Bearer token", "X-Custom-Header": "value"}' -- http://127.0.0.1:8001/sse
53	```
54
55	To use a Streamable HTTP-compatible MCP server, specify the server type and endpoint:
56
57	```bash
58	mcpo --port 8000 --api-key "top-secret" --server-type "streamable-http" -- http://127.0.0.1:8002/mcp
59	```
60
61	You can also run mcpo via Docker with no installation:
62
63	```bash
64	docker run -p 8000:8000 ghcr.io/open-webui/mcpo:main --api-key "top-secret" -- your_mcp_server_command
65	```
66
67	Example:
68
69	```bash
70	uvx mcpo --port 8000 --api-key "top-secret" -- uvx mcp-server-time --local-timezone=America/New_York
71	```
72
73	That’s it. Your MCP tool is now available at http://localhost:8000 with a generated OpenAPI schema — test it live at [http://localhost:8000/docs](http://localhost:8000/docs).
74
75	🤝 To integrate with Open WebUI after launching the server, check our [docs](https://docs.openwebui.com/openapi-servers/open-webui/).
76
77
78	### 🌐 Serving Under a Subpath (`--root-path`)
79
80	If you need to serve mcpo behind a reverse proxy or under a subpath (e.g., `/api/mcpo`), use the `--root-path` argument:
81
82	```bash
83	mcpo --port 8000 --root-path "/api/mcpo" --api-key "top-secret" -- your_mcp_server_command
84	```
85
86	All routes will be served under the specified root path, e.g. `http://localhost:8000/api/mcpo/memory`.
87
88
89	### 🔄 Using a Config File
90
91	You can serve multiple MCP tools via a single config file that follows the [Claude Desktop](https://modelcontextprotocol.io/quickstart/user) format.
92
93	Enable hot-reload mode with `--hot-reload` to automatically watch your config file for changes and reload servers without downtime:
94
95	Start via:
96
97	```bash
98	mcpo --config /path/to/config.json
99	```
100
101	Or with hot-reload enabled:
102
103	```bash
104	mcpo --config /path/to/config.json --hot-reload
105	```
106
107	Example config.json:
108
109	```json
110	{
111	"mcpServers": {
112	"memory": {
113	"command": "npx",
114	"args": ["-y", "@modelcontextprotocol/server-memory"]
115	},
116	"time": {
117	"command": "uvx",
118	"args": ["mcp-server-time", "--local-timezone=America/New_York"],
119	"disabledTools": ["convert_time"] // Disable specific tools if needed
120	},
121	"mcp_sse": {
122	"type": "sse", // Explicitly define type
123	"url": "http://127.0.0.1:8001/sse",
124	"headers": {
125	"Authorization": "Bearer token",
126	"X-Custom-Header": "value"
