IoMarkets.tech MCP

Remote MCP server providing tools to validate ISO 20022 messages, verify execution reports, check tokenized asset contracts, and retrieve corporate actions data for AI agents.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What you can do with it

  • Validate ISO 20022 messages against schema and business rules
  • Verify execution report signatures and payment proofs
  • Check if a token contract is the official tokenized fund
  • Retrieve corporate actions like dividends and splits

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Tools for IoMarkets.tech, open tools for capital-markets plumbing. list_corporate_actions and holdings_calendar give dividends, splits and mergers of US-listed companies from their SEC filings; get_corporate_action adds the seev.031 message. check_token_contract says whether a token contract is the issuer’s real tokenized fund or security (the Tokenized Asset Map). validate_message checks an ISO 20022 message (pacs.008, pacs.009, pain.001, camt.053, seev.031) against the official schema and business rules; explain_issue says how to fix each problem; list_samples and get_sample give valid and broken messages. The Data API tools list routes and prices, check status and verify signed proofs; explain_execution_request says exactly how to call the paid execution-quality audit, and verify_execution_report checks what it returned (signature, payment, row hash, each row re-scored against the trade and the arrival mid, and the summary recomputed from the rows: the same checks as the /execution-check page). Guides give exact button names. Nothing here pays, sends or stores anything: to buy data, an agent pays the Data API itself over x402.

verify_proof — Check a Data API proof
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

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).

Advertised by the server during the last successful anonymous check.
Advertised read-only

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), the price, what comes back, and the answers that are not charged (400 for a bad body or an unsupported pair, 422 when no fill matches a trade). Give a draft body to check it with the API's own validation first. Read from the API's code; this tool calls nothing and pays nothing.

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), that the rows hash to the signed audit_sha256, and that every row and the summary recompute with the API's own scoring, against the last trade and against the arrival mid (side-aware cost, qty-weighted averages, spread, matched and unmatched fills). The same checks as the page at https://iomarkets.tech/execution-check. Returns each check, and the recomputed summary as structured data.

check_token_contract — Is this the real tokenized security?
Advertised by the server during the last successful anonymous check.
Advertised read-only

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), unknown (not in the map, which says nothing either way).

Advertised by the server during the last successful anonymous check.

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 — Dividends, splits and mergers
Advertised by the server during the last successful anonymous check.
Advertised read-only

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 mergers (cash or shares per share). Filter by holdings (tickers, CIKs or FIGIs), by days (any of an event's dates between from and to) and by type. Each event links its filing and the sentence or table row it was read from. Also gives the iCalendar subscription URL for the same holdings and types (calendarUrl in structuredContent).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http iomarkets-tech-mcp https://iomarkets.tech/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add iomarkets-tech-mcp --url https://iomarkets.tech/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable iomarkets-tech-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "iomarkets-tech-mcp": {
      "url": "https://iomarkets.tech/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "iomarkets-tech-mcp": {
      "type": "streamableHttp",
      "url": "https://iomarkets.tech/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start iomarkets-tech-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "iomarkets-tech-mcp": {
      "type": "http",
      "url": "https://iomarkets.tech/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http iomarkets-tech-mcp https://iomarkets.tech/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "iomarkets-tech-mcp": {
      "url": "https://iomarkets.tech/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "iomarkets-tech-mcp": {
      "serverUrl": "https://iomarkets.tech/mcp"
    }
