Overview

Description from the maker (original English)

Research, inference, data/web/email tools, and x402 conformance, service catalog and grade feeds.

PopNx MCP’s three pillars

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

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.

  • search_services

    Find Mekler paid operations for a task, including exclusions and useful combinations.

  • get_service

    Get a complete public service or operation contract by slug, operation ID, name, or endpoint URL.

  • scan_origin

    Start or recover an asynchronous x402 conformance scan. For new origin-only calls, this MCP tool defaults to quote_mode fast and returns an unsigned 402 quote without starting a scan. Capability-only recovery requires the original input or proof; use get_scan_status for capabilit

  • get_scan_status

    Read a conformance job state with job_id and recovery_capability. Polling never starts work or settles payment.

  • get_scan_report

    Read a completed public cached report by report_id. Reports expire after 24 hours; this tool never purchases a replacement.

  • list_conformance_checks

    Read the versioned 25-check linter and separate 14-check compliance catalogs, grading rules and unknown-evidence semantics.

  • search_listings

    Find x402 services imported from attributed catalogs or scanned by Mekler. Filter by task text, host, category, network, source, tier, grade or owner control. Unknown grades, prices and health remain unknown. Payment-ready means a recent valid unsigned challenge; it does not cert

  • retrieve_listing

    Read one visible directory listing, attributed source assertions, measured reachability, endpoint offers and available linter grades. Imports start ungraded; identity-reviewed business wording does not verify seller claims or paid delivery. Never signs payments.

  • export_listings

    Export up to 10000 visible x402 directory services with attributed source facts, measured health and grade history, first seen, scan counts, provenance and explicit truncation. Returns gzip+base64 JSON and a digest; large results use a 60 second signed download URL. Costs 0.25 US

  • list_grade_changes

    Read ordered new, grade_changed and rescanned events with previous grades and scores. Default 200, maximum 1000; signed watermark cursors. History retains 30 days or 50000 events; expired cursors return 410. Costs 0.01 USDC per page on Base or Solana. Use a fresh idempotency key

  • start_ownership_proof

    Start a one-hour domain challenge bound to your private random 32-byte requester key in lowercase hex. Publish the returned JSON exactly at its HTTPS well-known URL. Keep the requester key private. An imported directory listing or completed scan is required before confirmation. N

  • confirm_ownership_proof

    Confirm a one-hour domain challenge with the same private requester key. Exact HTTPS origin and path must match. Returns a 90 day listing-control credential; identical retries recover that grant. A new proof revokes prior credentials. Confirmation does not approve branding or cha

  • update_listing_preferences

    Use X-Mekler-Listing-Control and the expected revision to hide a listing, suppress branding or revoke access. Domain proof is rechecked after seven days; failed, stale, revoked or expired credentials deny control. Concurrent writes return 409. Suppression affects current reads, n

  • request_listing_update

    Request a free reviewed listing correction with X-Mekler-Listing-Control, current revision, a fresh private requester_key and exact changes. Reuse that same requester_key and identical body after an uncertain response; it pins one request, and changed input conflicts. A verified

  • reissue_owner_token

    Request one email-based ownership-credential replacement for an existing verified private contact. POST origin for a uniform 202 response whether eligible or not. POST the same origin and recovery_code to confirm within 15 minutes. Domain control and original ownership scope are

  • list_categories

    Read categories present in visible identity-reviewed directory listings. Never signs payments.

  • list_networks

    Read canonical network identifiers in visible directory routes. Imported network claims are attributed and unverified until observed. Never signs payments.

  • list_offer_changes

    Read changes observed in unsigned payment challenges. Before/after fingerprints preserve payout privacy. A drained cursor advances to new observations on later polls; retain it. No paid delivery is inferred. Never signs payments.

  • retrieve_listing_history

    Page through Mekler uptime, latency or observed price history for one listing. Raw history retains 30 days; UTC daily aggregates are retained indefinitely. Unknown input/auth/rate-limit observations are excluded from uptime denominators. This is configuration/reachability evidenc

  • retrieve_health_checks

    Page through fixed safe monitoring observations for one listing or the whole visible catalog. Current hiding and attribution controls apply to retained history. No captured target body, contact or payout address is returned. Never signs payments.

  • summarize_directory_status

    Read measured online, degraded, offline and unknown states, delisted count and latest completed monitoring cycle. Missing checks remain unknown; this does not certify paid delivery. Never signs payments.

  • get_trial_offer

    Read the adjustable free-use offer, wallet authentication, allowance and explicit paid transition.

  • get_trial_access

    Get the service request and standard wallet-auth instructions. First signed execution enrolls automatically; no wallet funds or payment required.

  • rotate_trial

    Write: request a wallet-rotation challenge with old_wallet/new_wallet/request_id; then submit old_proof/new_proof signed with both keys. Usage is preserved.

  • referral_accept_terms

    Accept a newer version of the referral terms to keep earning. arguments: terms_version and terms_digest from referral_program. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

  • referral_acknowledge

    Mark notices already served by referral_notices as read up to a cursor. arguments: cursor (integer) and optional private_cursor. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

  • referral_notices

    Read published program notices and the referrer's private account events. arguments: optional cursor, limit (1-50) and private_cursor. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

  • referral_receipts

    Page through a referrer's commission receipts, oldest first. arguments: optional cursor (last seen) and limit (1-50). Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

  • referral_register

    Register a wallet as a Mekler referrer and receive a referral code. arguments: terms_version and terms_digest from referral_program, which explicitly accept those exact terms. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof

  • referral_rotate

    Move a referral registration to a new wallet without losing history. arguments: old_wallet and new_wallet; then send proof (old wallet) and new_proof (new wallet). Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment

  • referral_status

    Read a registered referrer's code, referral link, accepted versus current terms and whether action is required. arguments: none. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

  • referral_program

    Read current Mekler referral availability, terms and commission offer.

Common questions

Is Mekler AI 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 (0.1.14) reached the registry 8 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: Vexa, emailmd, MCP WhatsApp Cloud
