Assetlens MCP Server

assetlens

assetlens gives an agent read-only access to the public side of a marketplace for real-world assets — agro and energy first, growing into mining, equipment, and industrial services. It wraps the platform's anonymous tier: no account, no token, and nothing that writes. You can read the onboarding document, search marketplace listings, search projects, run one unified search across both, and fetch the full public document behind a search hit. One binary serves a command-line interface and a stdio MCP server.

The upstream is a hosted MCP endpoint spoken to over JSON-RPC 2.0. The anonymous tier is documented at 60 requests per minute per client; this tool simply forwards each call, unwraps the result envelope (the payload arrives as JSON inside the result's text content, mirrored in structured content), and prints what came back. Set EPINU_MCP_URL to point at a different endpoint; the documented production endpoint is the default.

Install

npx @reneturcios/assetlens search --query ASIC

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/assetlens

The container defaults to the MCP server (see below); pass CLI arguments to use it as a CLI instead.

CLI

assetlens getting_started
assetlens marketplace_listings_search --query "ASIC repair"
assetlens marketplace_listings_search --category equipment --max-price 3000 --limit 5
assetlens projects_search --query mining
assetlens search --query ASIC
assetlens fetch --id listing:f7edbcad-ecbc-46d0-a8f6-162fc8219089

assetlens --version

Every command prints the upstream payload as JSON (the onboarding document prints as text). Exit codes: 0 on success, 1 on a runtime or upstream error, 2 for usage errors. Arguments are validated before any network call: an undocumented category, a missing or over-long query or id, or an unknown flag is a usage error, never a network request.

Search arguments follow the platform's published tables exactly. For marketplace_listings_search and projects_search, the tables mark maxPrice, limit, and cursor optional and leave query (and category) unmarked, so none of them are required here. search requires query (1–200 characters) and fetch requires id (1–120 characters). category accepts only product, service, repair_services, equipment, or energy.

What the tools return

• marketplace_listings_search returns results (listings with fields such as listing_id, title, category, pricing_mode, price — a number or null — status, and location_address), a next_cursor (null when there is no further page), and the limit used.
• projects_search returns projects, each with project_id, name, and summary.
• search is deliberately shallow: each hit carries only id, title, and url. The id is prefixed — project:<uuid> or listing:<uuid> — so you can tell which side of the platform a hit came from.
• fetch returns the full document for one id: id, title, text, url, and metadata (for a listing, its type, category, pricing_mode, price, availability_type, and location_address). An unknown or malformed id is an upstream tool error — Resource not found. with status code 404 — and assetlens surfaces it as an error rather than inventing a result.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/assetlens mcp

MCP client configuration:

{
  "mcpServers": {
    "assetlens": {
      "command": "npx",
      "args": ["-y", "@reneturcios/assetlens", "mcp"]
    }
  }
}

Tools

What is not included

With a delegated token the same platform exposes more tools — identity, proposal-creating writes, and proposal listing among them (whoami, marketplace_listing_create, project_create, proposals_list_my, and further unnamed scoped tools, plus the projects_get_deep_dive and marketplace_listing_get calls that fetch wraps upstream). The platform names those tools in prose but publishes no argument tables for them, so they are omitted here rather than rebuilt from guesses. Nothing in this package creates proposals or writes anything.

Development

npm install
npm run build   # tsc -> dist/
npm test        # node test runner over test/*.test.ts, fake fetch only — no network
npm run dev     # run the CLI from source via tsx
