For agents & builders

Onchain Agent MCP Server

Sato Hub is the resource hub for onchain agents — and it speaks the agents' own protocol. This server exposes the directory, wiki, news, and live metrics over the Model Context Protocol, so any MCP client — Claude, your own harness, or an agent you're building — can query it directly. Read-only, no key required.

Connect

Claude & other remote-connector clients

In Claude (or any client that supports remote MCP connectors), add a custom connector and paste the endpoint URL above. No further configuration is needed.

Local / stdio clients (Claude Desktop config, Cursor)

For clients that connect over stdio, bridge to the remote endpoint with mcp-remote:

{
  "mcpServers": {
    "onchain-agent": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://satohub.ai/api/mcp"]
    }
  }
}

Inspect it

Point the MCP Inspector at the endpoint to browse the tools live:

npx @modelcontextprotocol/inspector
# transport: Streamable HTTP → https://satohub.ai/api/mcp

Tools

Eight read-only tools. Every list tool paginates and accepts response_format of markdown (default) or json.

onchain_agent_search_resources

Search and filter the directory by free text, chain, category, status, liveness, and the agent / skill / framework flags. Sortable and paginated.

onchain_agent_get_resource

The full record for one resource by slug, with its recent release and post activity.

onchain_agent_list_categories

Every resource category with counts, most populated first.

onchain_agent_list_chains

Every blockchain represented in the directory, with resource counts.

onchain_agent_get_news

The filtered news feed — official releases, project announcements, and reputable RSS — by kind or chain.

onchain_agent_get_metrics

Live ecosystem metrics: the ERC-8004 registered-agent count (read from Ethereum mainnet) and the curated project-token index.

onchain_agent_get_wiki_page

A full wiki explainer by slug — summary, how it works, key components, risks, related resources.

onchain_agent_list_wiki_pages

Every wiki page with its title, keyword, and summary.

Notes

Read-only. The server makes no writes and signs no transactions. Submissions and briefing signups live on the website forms.
Same data, same rules. It returns exactly what the site shows — no new claims. Verification status distinguishes self-reported from verified, and retired projects are never returned.
Fair use. The endpoint is open and unmetered for now. Be reasonable; heavy or commercial use may be rate limited later.

Building an onchain agent? Submit it to the directory — it'll show up here, queryable by every agent on the protocol.
