Ground your AI agents. In the live web, not guesses.
Give agents a web search tool and a fetch tool that return clean, relevant content with sources. Fewer hallucinations and fewer wasted tokens, through one SDK or MCP server.

“This has allowed us to equip the agent with up-to-date context on the hardware, tools, frameworks, etc. it’s using, and thus make it massively more reliable.”
- lower total LLM and retrieval costs for freecode, fees included
- 8.9%
- for Scira AI to add, test, and deploy web search

Two tools every agent needs.
Search finds the right pages and returns highlights, the passages that match the query. Fetch reads any URL as Markdown. Your agent answers from both and cites them.

What is AI grounding?
AI grounding connects a model’s answer to real, current sources instead of only its training data. Grounded agents search the web, read the relevant pages, and cite them. Context.dev gives agents both tools through one API.
How does grounding reduce AI hallucinations?
A grounded agent answers from pages it just retrieved instead of guessing from training data, and it can cite those pages. Highlights keep only the passages that match the query, so the model reads less noise. freecode measured 9.8% fewer input tokens with Highlights.
How is this different from grounding with Google Search?
Grounding with Google Search is built into Gemini models. Context.dev works with any model or agent framework: call Search and Scrape from your own tool loop or connect the MCP server, and use the pages and highlights however you want.
Can I give my agent web access over MCP?
Yes. Add https://mcp.context.dev/mcp to Claude Code, Cursor, Codex, or another MCP client. Sign-in uses OAuth, so no API key goes into the config file.
How much does grounding cost?
Search costs 1 credit per 10 results, and Highlights add 1 credit per 10 results. Fetching a page as Markdown costs 1 credit. The free plan includes 1,000 credits every month.
