Groundlink MCP Server

Use Groundlink's cited web-search results from any Model Context Protocol (MCP) host. The server exposes one focused tool, groundlink_search, which sends a query to Groundlink and returns source-bearing results (title, url, snippet, and source) for the model to use when it needs evidence rather than a guess.

Groundlink currently combines Wikipedia and DuckDuckGo results. Each Groundlink API key includes 100 free test queries; after that, prepaid usage is $0.001 per query (one credit per query).

Package: groundlink-mcp@0.1.1 is published on npm. Source: https://github.com/ohhavefun/groundlink

Live API documentation: https://9ea69cec60fa01f65bbb647a092bcbb4.ctonew.app/docs
Pricing and credits: https://9ea69cec60fa01f65bbb647a092bcbb4.ctonew.app/pricing

This repository is the home of Groundlink's official developer integrations. There are two, both maintained here:

Integration	What it is	Install
groundlink-mcp (MCP server)	Exposes Groundlink to any MCP host (Claude, Cursor, …)	`npm install -g groundlink-mcp` (also on the official MCP registry as `io.github.ohhavefun/groundlink`)
langchain-groundlink (Python/LangChain)	A `GroundlinkSearchTool` for Python agents	`pip install "langchain-groundlink @ git+https://github.com/ohhavefun/groundlink#subdirectory=langchain-groundlink"`

Both use the same free trial keys (100 queries) from the Groundlink onboarding, then prepaid usage at $0.001/query.

Where Groundlink is listed

langchain-groundlink (Python / LangChain)

Use Groundlink's cited search from any Python agent or BaseTool pipeline. The tool returns source-bearing results (title, url, snippet, source) so your agent answers from evidence and can cite it.

Install from GitHub (the package is intentionally not on PyPI):

pip install "langchain-groundlink @ git+https://github.com/ohhavefun/groundlink#subdirectory=langchain-groundlink"

Quick usage (10 seconds): get a free key from the docs, then:

from langchain_groundlink import GroundlinkSearchTool

tool = GroundlinkSearchTool(api_key="glk_your_trial_key")  # or export GROUNDLINK_API_KEY
result = tool.invoke({"query": "Who was Ada Lovelace?"})
print(result)

Full usage, configuration, and error handling are in langchain-groundlink/README.md.

Groundlink MCP Server

Use Groundlink's cited web-search results from any Model Context Protocol (MCP) host below.

Field	Value
Tool name	`groundlink_search`
Input	`{ query: string, max_results?: number }`
`max_results`	1–10; default 5 (or `GROUNDLINK_MAX_RESULTS`)
Output	JSON: `{ query, results: [{ title, url, snippet, source }], meta }`

Use it for factual questions where the host should return URLs/sources with its answer. The MCP server is deliberately thin: it forwards the query to the Groundlink HTTPS API and returns the API response over MCP stdio.

Install and run

You need a Groundlink API key (glk_...). Ask the Groundlink operator for one or obtain one through the Groundlink onboarding flow.

npm install -g groundlink-mcp
export GROUNDLINK_API_KEY=glk_your_key_here
groundlink-mcp

Alternatively, an MCP host can execute the package without a global install:

npx -y groundlink-mcp

The process uses stdio; it does not open an HTTP port or print normal output to stdout. MCP hosts should launch it rather than running it interactively.

Configuration

Variable	Required	Default	Meaning
`GROUNDLINK_API_KEY`	Yes	—	API key used for every Gr
