Overview

Description from the maker (original English)

Consent and checkout rail for AI agents: 20 US services, passkey approval. Sandbox: simulated data.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 17 things (tools) moltbound_list_services, moltbound_start_session, moltbound_requirements, moltbound_get_quotes …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • moltbound_quote_status

    Poll a quote job until complete, then show the human the quotes. Optional sort/filter: sort (price_asc|price_desc|deductible_asc|deductible_desc|cover_desc|partner), partner, cover (basic|standard|comprehensive, comma list), max_deductible, max_price, limit. The human picks which

  • moltbound_complete_purchase

    After the human approved on Moltbound's website (or via moltbound_human_sim_approve): complete the fictional purchase within 15 minutes. Bound to that exact quote and agent: repeating the call for the same approved quote is idempotent (returns the existing purchase_id), while reu

  • moltbound_purchase_status

    Poll the status of a fictional purchase by purchase_id until 'bound'. Returns partner's policy_number. SANDBOX: use fictitious data only. Do not enter real personal details.

  • moltbound_quick_quote

    One-shot quotes across any service. Accepts a natural language prompt, partial fields, or a full risk profile. When auto_default is true, missing fields are populated with safe sandbox defaults (car insurance driver fields numberOfDrivers and driverAges are filled only when both

  • moltbound_request_grant

  • moltbound_poll_grant

  • moltbound_human_sim_verify

    Verify the 6-digit email code from moltbound_human_sim_start. Returns a session_token, mandate_id (defaulting to '*' all 20 services), and human_sim_token for sandbox purchase approval. SANDBOX: use fictitious data only. Do not enter real personal details.

  • moltbound_human_sim_approve

    Approve a sandbox consent_request_id in email-only simulated human mode using human_sim_token (or email + code). Never billable. SANDBOX: use fictitious data only. Do not enter real personal details.

Common questions

Is Moltbound safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP
