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 6, 2026. The maker wrote them, not us; we show them as plain text.

  • get_overview

    What IoMarkets.tech is and what is built: the ISO 20022 Test Bench, the Data API (market data for AI agents, paid per request over x402), the main pages, and what comes next.

  • get_guide

    Step-by-step instructions, with the exact button names, for one task on iomarkets.tech (checking a message, CI, verifying a proof, calling the Data API…). Without a task, lists the tasks.

  • explain_term

    A plain-English meaning of a word used on the site (ISO 20022, schema, IBAN, BIC, LEI, ISIN, UETR, CBPR+, x402, signed proof, MCP…) or of an ISO 20022 XML tag abbreviation such as GrpHdr, CdtrAcct or IntrBkSttlmAmt. Without a term, lists the words.

  • list_messages

    The ISO 20022 message types and versions the Test Bench checks, with what each is for.

  • validate_message

    Check one ISO 20022 XML message (pacs.008.001.08, pacs.009.001.08, pacs.002.001.10, pacs.004.001.09, pain.001.001.09, camt.053.001.08, camt.054.001.08 or seev.031.001.14) against the official base schema, then business rules (check digits, totals, cross-element rules, market prac

  • explain_issue

    What a Test Bench issue code (such as IBAN_CHECKSUM, BALANCE_MISMATCH or OUT_OF_ORDER) means and how to fix it. Without a code, lists every code.

  • list_samples

    The Test Bench sample library: a valid message of each type and broken ones, each with the issue code it raises. Use get_sample for the XML.

  • get_sample

    The XML of one sample message from list_samples, to use as a starting point or in tests. Every party and account in it is made up.

  • list_data_endpoints

    The Data API routes at https://api.iomarkets.tech, what each returns and its price per call in USDC, with how an AI agent pays (x402 on Algorand mainnet, no account).

  • get_api_status

    Whether the Data API at https://api.iomarkets.tech is answering right now, from its /health check.

  • estimate_data_api_cost

    What a monthly volume of Data API calls costs at the per-call x402 prices, against the indicative subscription plans. Give calls per month for each route; routes left out count as zero.

  • verify_proof

    Check a signed proof (the { payload, signature } JSON a Data API proof route returns): that the ed25519 signature matches the published IoMarkets key, and that its USDC payment is confirmed on Algorand mainnet (looked up on a public indexer IoMarkets does not run).

  • explain_execution_request

    Exactly how to call POST https://api.iomarkets.tech/v1/proof/execution, the paid best-execution audit: the body (pair, one of BTC-USDC, ETH-USDC, SOL-USDC, and fills: ts, fill_price, qty, side), the limits (fills per call, how old a fill may be, how close the market trade must be

  • verify_execution_report

    Check the whole JSON that POST https://api.iomarkets.tech/v1/proof/execution returned ({ audit, summary, attestation }): that the ed25519 signature matches the published IoMarkets key, that its USDC payment is confirmed on Algorand mainnet (a public indexer IoMarkets does not run

  • check_token_contract

    Check a token contract against the Tokenized Asset Map: is it the issuer's own contract for a tokenized fund or security on that chain? Verdicts: official, other-chain (the address is listed, but on another chain), impostor (a listed symbol on this chain, a different contract), u

  • list_tokenized_assets

    The securities in the Tokenized Asset Map with their identifiers (FIGI, ISIN where the issuer gives it) and the chains they are tokenized on. Optionally filter by issuer, name, symbol, ticker, ISIN or FIGI.

  • get_tokenized_asset

    One Asset Map entry in full: the security, every token contract chain by chain, the issuer sources each comes from, and whether its IoMarkets signature verifies.

  • verify_asset_with_issuer

    Fetch the issuer's own sources for one Asset Map entry now (its contracts page, its public API, or its stellar.toml) and confirm every listed contract is still there, so trust needn't rest on IoMarkets.

  • list_corporate_actions

    Corporate actions of US-listed companies from their own SEC EDGAR filings (8-Ks of US companies, 6-Ks of foreign private issuers): cash dividends (amount in the stated currency, per share or per ADS, ex, record and payment dates), stock splits, reverse splits and completed merger

  • holdings_calendar

    For a list of holdings (tickers, CIKs or FIGIs), every ex-date, record date, payment date and effective date in one week, day by day. The week holding `day`, Monday to Sunday; this week by default. Ends with an iCalendar (webcal) subscription URL for those holdings, to give the u

  • get_corporate_action

    One event in full: every date and term, the filing and the sentence or table row it came from, tokenized versions in the Asset Map, and the event as an ISO 20022 seev.031.001.14 notification (checked by the Test Bench).

  • token_corporate_actions

    For a token contract that the Asset Map lists as a tokenized stock or ETF (such as an xStock): the security it tracks, and that security's dividends, splits and mergers from the corporate actions feed, each with what it does to the token. Answers 'I hold this token; what is comin

  • get_roadmap

    What IoMarkets.tech has built and is building next, in the same words as iomarkets.org/roadmap.

Common questions

Is IoMarkets.tech ISO 20022 Test Bench 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 (1.0.0) reached the registry 11 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?
