MarketNow — Trust Infrastructure for AI Agents

Repo ecosystem (one owner per concern, split 2026-09-26):

RepoSole owner of
alicelabs-llc/MARKETNOW (this repo)Product code: mcp-server (npm marketnow-mcp), atc-sdk/atc-python/atc-rust, Docker/Cline/Cursor integrations, CLIs, security audits
eddyflores100-lang/marketnowLive marketplace: site (aep-marketplace/), catalog data (_data/, skills/, public/api/), the 21 scheduled data pipelines, Vercel deploys of marketnow.site
alicelabs-llc/universal-trust-adapterATC/1.0 protocol: spec, adapters, reference implementation, plugins
alicelabs-llc/marketnow-submissionsPublic skill submissions queue

Data and site questions go to the marketplace repo; protocol questions to UTA; everything else lives here.

MarketNow doesn't sell AI tools. It determines whether AI agents should be allowed to trust and execute them.

What is MarketNow?

MarketNow is trust infrastructure for AI agents: a hosted registry that verifies skills, credentials and domains across 68,388 indexed MCP servers (132,737 tracked across GitHub, npm and PyPI), with signed skill submissions, revocation checks and a 9-tool MCP API.

Every indexed entry is security-first scored. The MCP API is free — 68,387 of the 68,388 indexed servers are free to install (paid: 1 in the public stats API).

The 9 MCP tools (endpoint v1.16.0)

Endpoint tracks the npm train: v1.16.0 (2026-10-05 — auth-gate join in /api/skills: requires_auth / auth_state / rfc9728_valid on 6,165 probed skills, ?auth= filters, auth_gate response block); previously v1.15.0 (2026-09-26).

The MCP server exposes 9 tools, all under the marketnow_* namespace so Claude Desktop, Cursor, Cline, LangChain and LlamaIndex can disambiguate them at tool-choice time:

#ToolWhat it does
1marketnow_verify_trustVerify any AI-agent credential (JWT, W3C VC, MCP Card, ATC v3, A2A, EAT-AI, ZTA, X.509) through the UTA 12-stage verification pipeline
2marketnow_translate_credentialTranslate a credential between 8 formats (ATC v3, JWT, W3C VC, A2A, EAT-AI, ZTA, MCP Card, X.509) losslessly via the Universal Trust Schema
3marketnow_list_formatsList the 8 supported credential formats with their algorithms and status
4marketnow_get_pipelineGet the 12-stage verification pipeline details
5marketnow_check_domainScam checker: returns a domain risk score with reasons
6marketnow_search_skillsSearch the registry of indexed MCP servers (GitHub, npm, PyPI), security-first scored
7marketnow_check_revocationCheck revocation of an Agent Trust Card or CA key against the signed Revocation Registry (MNR-CRL-1.0) + live ledger
8marketnow_fingerprint_toolCryptographically fingerprint MCP tool definitions (OWASP MCP Cheat Sheet) with RFC 8785 JCS + SHA-256
9marketnow_submit_skillPublish a skill to the catalog: validated and Sentinel-scanned (injection patterns, embedded secrets, dangerous capabilities)

Tool contract: deterministic marketnow_ snake_case names · intent-oriented descriptions · strict JSON-Schema parameters · structured { content, isError } responses.

Quick start

Add to Cursor — 1 click (no terminal)

Connect any MCP client (Streamable HTTP)
{
  "mcpServers": {
    "marketnow": {
      "url": "https://www.marketnow.site/api/mcp"
    }
  }
}
Run the MCP server
npx -y marketnow-mcp
Run it in Docker (audited repo tree, published by CI)
docker run -i --rm ghcr.io/alicelabs-llc/marketnow-mcp:1.16.0
# or register it in the Docker MCP Toolkit:
docker mcp gateway add --docker ghcr.io/alicelabs-llc/marketnow-mcp
Cline

Paste the ready block from integrations/cline/cline_mcp_settings.json into Cline → MCP Servers → Configure. The repo also ships .clinerules/ house rules. Guide: integrations/cline/README.md.

Cursor

Open this repo as your Cursor workspace — .cursor/mcp.json auto-registers the server, and .cursor/rules/marketnow.mdc teaches Cursor the house rules. Guide: integrations/cursor/README.md.

Source of truth: https://www.marketnow.site/api/stats.json — CI fails if any surface diverges.

Security model

Two levels:

  • L1 — index certification: all 68,388 entries pass 10 metadata/security checks before being indexed.
  • L2 — Sentinel scans: shipped npm tarballs are scanned (2,839 to date) for injection patterns, embedded secrets and dangerous capabilities. Skills that fail are quarantined and published in the transparency report.

Conformance
