iso20022-mcp: The Unified MCP Gateway for ISO 20022

One Model Context Protocol server, one small set of meta-tools —search, list_families, describe, validate, generate, parse — thatroute across every ISO 20022 message family (pain · pacs · camt ·acmt). Install one thing, discover the whole suite: an agent sees a handfulof verbs instead of the 60+ tools spread across five individual servers.

Latest release: v0.0.1 — 6 routing meta-tools over stdio, light core(only mcp), backing family servers as optional extras, for Python 3.10+.The front door to the ISO 20022 MCP suite.

Why a gateway

The suite has a dedicated, best-in-class server per message family. That depthis the point — but an agent shouldn't have to know which of five servers andwhich of sixty tools it needs before it can act. iso20022-mcp is the thinrouting layer on top: ask it in plain terms ("I need to reconcile astatement", "generate a credit transfer"), and it points you at — or executesagainst — the right family. Small tool surface, whole-suite reach.

Install

The core is light. Add the families you need as extras (or [all]):

pip install "iso20022-mcp[all]"       # every family
pip install "iso20022-mcp[pacs,camt]" # just interbank + statements
pip install iso20022-mcp              # core only; families report as not installed
# or run without installing:
uvx --from "iso20022-mcp[all]" iso20022-mcp

MCP client config (e.g. Claude Desktop):

{
  "mcpServers": {
    "iso20022": {
      "command": "iso20022-mcp"
    }
  }
}

The meta-tools

Tool	What it does	Families
`search`	Find message types by use-case / keyword ("reconciliation", "pacs.008").	all (catalogue)
`list_families`	List families, their capabilities, and which backing packages are installed.	all
`describe`	Required fields + input JSON Schema for a message type.	all
`validate`	Validate records against a message type's schema.	all
`generate`	Generate a validated ISO 20022 XML message from records.	pain · pacs · acmt
`parse`	Parse an inbound ISO 20022 XML message into structured data.	pacs · camt

Operations are capability-aware: generate on a camt.053 statement (aninbound format) returns a clear, explanatory error rather than failingobscurely, and every "package not installed" case tells you exactly what topip install.

Routing

Prefix	Family	Backing server	generate	parse
`pain`	Customer Credit Transfer Initiation	`pain001-mcp`	✅	—
`pacs`	FI-to-FI Customer Credit Transfer	`pacs008-mcp`	✅	✅
`camt`	Bank-to-Customer Statement	`camt053-mcp`	—	✅
`acmt`	Account Opening Instruction	`acmt001-mcp`	✅	—

The gateway imports each backing server lazily and optionally — the coredepends only on mcp, and a family's server is loaded on first use. Messagetypes are matched on their prefix (pacs.008.001.08 → pacs).

Example

search(query="reconciliation")
  → [{ "message_type": "camt.053", "family": "camt", "package": "camt053-mcp" }]

describe(message_type="pacs.008")           # required fields + input schema
validate(message_type="pacs.008", records=[…])
generate(message_type="pain.001", records=[…])   # → validated XML
parse(message_type="camt.053", xml="<Document>…")

For the dedicated reconciliation engine that matches camt.053 statementsagainst expected pain.001 payments, see reconcile-mcp.

The suite

iso20022-mcp is the front door to a family of vendor-neutral, Python-nativeISO 20022 MCP servers:

pain001-mcp — customer credit transfer initiation.
pacs008-mcp — FI-to-FI credit transfers.
camt053-mcp — bank-to-customer statements.
acmt001-mcp — account opening instructions.
reconcile-mcp — explainable statement/payment reconciliation.
bankstatementparser-mcp — MT94x / BAI2 / OFX parsing.
