The io.github.TinySuiteHQ/tinysearch MCP server provides a self-hosted web research capability for MCP agents. It is positioned as a web research service that can be run privately, enabling agents to perform research tasks using an external web information source without relying on a hosted alternative.

⚠️ Limitations
Available metadata describes only “self-hosted web research for MCP agents” and does not specify tools, interfaces, or capabilities beyond that.
TinySearch is a self-hosted web-research tool for AI agents. It searches the
web, reads the best pages, removes low-value content, and returns compact
evidence with source URLs.
Your model receives the useful passages instead of paying to process entire
webpages.
TinySearch is part of TinySuite, a suite of focused
tools designed to make agentic operations cheaper by minimizing token usage
through smart retrieval, selection, and context-management techniques.

Tier
Use it when
Entry point
Search backend
1. Python library
You are building with TinySuite or Python
pip install tinysuite-search
DDGS
2. One-command MCP
An MCP client should launch TinySearch for you
uvx --from "tinysuite-search[server]" tinysearch
DDGS
3. Docker + SearXNG
You want the full self-hosted stack and HTTP MCP
docker compose ... up -d
Bundled SearXNG
Tiers 1 and 2 need no search service. Tier 3 adds a dedicated SearXNG service,
persistent model storage, and a network MCP endpoint. See the
installation guide for the Docker
setup.
The expensive part of agent research is context
A search result is not yet useful evidence. Agents often have to open several
pages, ingest navigation and boilerplate, and spend paid input tokens deciding
which passages matter.
TinySearch moves that work in front of the model:
flowchart LR
A[Question] --> B[Search and crawl]
B --> C[Local hybrid reranking]
C --> D[Compact evidence<br/>with source URLs]
D --> E[Your agent]
That lowers cost in three ways:
Smaller model context. Only the best-ranked evidence chunks are returned,
within a controlled evidence budget.
No metered search API required by default. TinySearch can search through
DDGS without a paid search provider.
Local retrieval by default. ONNX embeddings and hybrid reranking run on
your machine instead of creating embedding API charges.
Search broadly. Read locally. Pay the model only for the evidence that matters.
Actual savings depend on the pages, evidence limits, client model, and provider
pricing. TinySearch reduces the web content sent to the model; it does not
control what the client does with that evidence afterward.
The naive baseline isn't a strawman product, it's the same pages TinySearch
crawled for each query, fed to the model unfiltered, the way a generic
"search, then fetch the page" tool (a plain web-search-plus-fetch loop, the
kind built into most coding agents) would. Reproduce or rerun it yourself:
The client launches TinySearch over stdio when it needs it. No repository
clone, hosted account, or paid search key is required.
On first launch, TinySearch installs Chromium and downloads the local
embedding model before it starts accepting requests, a one-time delay of a
minute or two. To avoid that delay on the first real query, pre-warm both
ahead of time:
Prefer Docker, a remote MCP endpoint, or a source checkout? Follow the
installation guide.
Three focused tools
Tool
Use it when
research(query)
The agent needs to discover and compare relevant sources
scrape_url(url, query)
You already know which page should be inspected
get_current_datetime()
Research depends on the current date or time
TinySearch deliberately stays focused. It is a retrieval layer, not another
agent, chat interface, hosted search product, or permanent web index.
See the complete MCP tool reference
for parameters and response contracts.
What your agent gets
TinySearch does not spend another model call writing the final answer. It gives
your existing agent ranked, source-grounded evidence to reason over.
An abridged structured result looks like this:
json
{"schema_version":"1","operation":"research","status":"ok","query":"How does asyncio cancellation work?","sources":[{"title":"Coroutines and Tasks","url":"https://docs.python.org/3/library/asyncio-task.html","chunks":[{"text":"Tasks can be cancelled...","tokens":146,"rank":1,"scores":{"rrf":0.91,"dense":0.88,"bm25":0.79}}]}],"stats":{"search_results":10,"sources_crawled":4,"chunks_considered":86,"chunks_selected":8}}
MCP tools return the same evidence as a grounded prompt by default, ready for
the client model to use. Pass output_format: "json" when you want the
structured result directly.
How it works
Search the web with DDGS or your own SearXNG instance.
Hybrid-rank the search results to choose which pages are worth reading.
Crawl those pages in parallel and extract readable content.
Chunk, deduplicate, and hybrid-rank the combined evidence pool.
Return the best passages with their titles, URLs, ranks, and scores.
Dense and lexical ranking happen before the evidence reaches your model. The
model gets a small, relevant research packet rather than a pile of raw pages.
Python library
TinySearch also works as a regular Python package:
bash
pip install tinysuite-search
python
import asyncio
from tinysearch import research, to_prompt
asyncdefmain():
evidence = await research("How does asyncio cancellation work?")
print(evidence["sources"])
print(to_prompt(evidence))
asyncio.run(main())
The Python API returns a stable, JSON-serializable evidence schema. Rendering
that evidence into an LLM prompt is explicit, so applications can store,
inspect, transform, or budget the result first.
Search backends
TinySearch selects a web-search backend from config, so you can start with no
search service and add one later without changing code.
"ddgs" (native default): queries the ddgs
package's automatic backend selection in-process. No SearXNG deployment
required.
"searxng" (Docker default): queries a self-hosted SearXNG instance. Falls
back to ddgs on backend failure unless search_backend_fallback is set to
false.
"duckduckgo": skips SearXNG and queries ddgs in DuckDuckGo-only mode.
"auto": tries SearXNG, then falls back to ddgs on any backend failure.
Set the BRAVE_SEARCH_API_KEY environment variable to add Brave's official
Web Search API as a keyed fallback for the ddgs and duckduckgo backends.
Brave is only consulted when the primary call errors or returns no results.
Full key reference, SearXNG JSON-output setup, and Compose details live in the
configuration reference.
Why TinySearch
Built around token efficiency. Page selection and passage selection
happen before content enters model context.
Source-grounded by construction. Every evidence group stays attached to
its originating URL.
Useful without paid infrastructure. DDGS search and local ONNX embeddings
are the defaults.
Bring your own stack when needed. SearXNG and OpenAI-compatible embedding
providers remain optional.
Works where agents already work. Use MCP over stdio, Streamable HTTP,
Python, FastAPI, or Docker.
Self-hosted and inspectable. No TinySearch account, analytics service, or
hosted scraped-data cache.
Part of TinySuite
TinySuite is a product suite built around one idea:
agents should spend tokens on useful work, not operational overhead.
Each tool focuses on a different part of the agent workflow and uses targeted
techniques to reduce unnecessary context before it reaches the model.
TinySearch handles the web-research layer by turning pages into a small,
ranked, source-grounded evidence packet.
Documentation
The README is the product overview. Detailed setup and operational material
lives in the TinySuite documentation:
TinySearch reads public pages and returns selected excerpts to the calling
client. Search, crawling, local embeddings, and reranking can run without
sending page content to an embedding provider. If you choose an
OpenAI-compatible embedding backend, that provider receives the text sent for
vectorization.
