@openserp/mcp

Model Context Protocol server for OpenSERP OSS and OpenSERP Cloud. It gives MCP clients search, image search, single and batch URL extraction, usage, and engine metadata tools.

When OPENSERP_API_KEY is not set, the server uses OSS mode at http://localhost:7000 and writes:

[openserp-mcp] No OPENSERP_API_KEY set - using OSS mode at http://localhost:7000.
[openserp-mcp] Get an API key: https://openserp.org/dashboard/keys
[openserp-mcp] Docs: https://openserp.org/docs | Issues: https://github.com/openserpapi/mcp/issues

Set OPENSERP_API_KEY to use OpenSERP Cloud. API keys are available at https://openserp.org/dashboard/keys. Set OPENSERP_BASE_URL to target another compatible OpenSERP API base URL.

Install

npm install -g @openserp/mcp

You can also run it without installing:

npx -y @openserp/mcp --stdio

Tools

Quick Examples

Ask your MCP client to:

• Search Google for current docs and return the top 5 URLs.
• Compare Google and Bing results for an SEO keyword.
• Extract clean Markdown from a URL before passing it to an LLM.
• Ground an answer in several sources at once with batch_extract - up to 20 URLs in one round-trip, where a dead link returns an error item instead of failing the batch.
• Read a geo-fenced page as a local visitor by passing region: "DE".
• Check remaining Cloud credits with get_usage.

Claude Desktop

Local OSS mode:

{
"mcpServers": {
"openserp": {
"command": "npx",
"args": ["-y", "@openserp/mcp"]
}
}
}

Cloud mode:

{
"mcpServers": {
"openserp": {
"command": "npx",
"args": ["-y", "@openserp/mcp"],
"env": {
"OPENSERP_API_KEY": "osk_live_..."
}
}
}
}

Cursor

For stdio use, add an MCP server entry:

{
"mcpServers": {
"openserp": {
"command": "npx",
"args": ["-y", "@openserp/mcp"],
"env": {
"OPENSERP_API_KEY": "osk_live_..."
}
}
}
}

For remote-style HTTP use, run:

npx -y @openserp/mcp --http --host 127.0.0.1 --port 3333

Then point a streamable HTTP MCP client to:

http://127.0.0.1:3333/mcp

Clients that still use the older SSE transport can connect to:

http://127.0.0.1:3333/sse

Environment

• OPENSERP_API_KEY: Cloud API key from https://openserp.org/dashboard/keys.
