What is Infomesh?
Infomesh is a fully decentralized peer-to-peer search engine for LLMs, accessible via the Model Context Protocol (MCP). It requires no API keys, credit cards, or usage caps, and is designed for AI developers, open-source assistants, and researchers who need free real-time web search.
How to use Infomesh?
Install Infomesh with pip install infomesh or via the uv package manager. Run the node to join the P2P network, then search from any MCP client, the CLI (infomesh search), Python code, or a local HTTP API. No sign-up or configuration is needed beyond installation.
Key features of Infomesh
- Fully decentralized P2P network with no central server
- No API key, billing account, or usage cap required
- Offline search using a local index
- Self-hosted; you own your node and data
- Crawl and index your own URLs
- Ed25519 cryptographic identity and encrypted transport
Use cases of Infomesh
- AI assistants (e.g., Claude, VS Code Copilot) that need free web search via MCP
- Local LLMs and open-source projects that cannot afford commercial search APIs
- Researchers crawling and indexing custom content for offline use
- Developers embedding search in applications via Python or HTTP endpoints
FAQ from Infomesh
How does Infomesh compare to other free web search MCP servers?
Infomesh is the only fully decentralized, offline-capable MCP server with no API key, unlimited free search (credit-based), and support for crawling your own URLs. It does not rely on a central provider or SaaS dependency.
What are the runtime requirements?
Infomesh requires Python 3.12+ and a Linux terminal (Ubuntu, Debian, etc.). No prior Python or developer experience is needed. The uv package manager is optional but recommended.
Where is my data stored?
Search queries are processed locally or routed as hashed keywords through the DHT. Your data never leaves your node unless you choose to share it. Crawled content is fingerprinted, signed, and published to the DHTโno central server stores your search history.
Are there any limits on usage?
Search is credit-based: you earn credits by contributing crawling to the network. There are no per-query costs, rate limits per dollar, or fixed monthly caps. New nodes have a 24-hour probation period, and per-keyword DHT publish rate is limited to 10 per hour per node.
What transports and authentication does Infomesh support?
Infomesh supports MCP (for AI assistants), CLI, Python package, and local HTTP API. Authentication uses Ed25519 cryptographic keys generated on first launchโno API keys or billing accounts are required. All peer-to-peer communication is encrypted via libp2p's Noise protocol.
