A [Model Context Protocol][mcp] server that exposes the [`acmt001`][core] ISO 20022 Account Management library as tools for AI agents and assistants — discover message types, inspect input schemas, validate records and financial identifiers, and generate validated XML, all from your favourite MCP client.
Latest release: v0.0.15: 7 MCP tools over stdio, streamable HTTP or SSE, all backed by the sharedacmt001.serviceslayer, for Python 3.11+. Ships in lockstep withacmt0010.0.15; every CI and image install is hash-pinned, and the tools are fuzzed. [See what's new →][release-0015]

The [Model Context Protocol][mcp] (MCP) is an open standard that lets AI agents and assistants discover and call external tools in a uniform way. acmt001-mcp is an MCP server that turns the [acmt001][core] library into a set of first-class agent tools, so an assistant can generate and validate ISO 20022 `acmt` Account Management XML messages — the standardised instructions, confirmations, and reports that govern the lifecycle of a bank account (opening, maintenance, closing, identification, and switching) — directly from a conversation.
Every tool is a thin, typed wrapper over acmt001.services — the single shared facade also used by the CLI and REST API — so all interfaces behave identically. Tools return JSON-serialisable data; on a validation error they return an {"error": ...} payload rather than raising.
This package is part of the acmt001 suite — a set of independently installable packages that share the acmt001.services layer:

python -m pip install acmt001-mcpNote: while the core acmt001 library is not yet on PyPI, install it from source first:>
``sh python -m pip install "git+https://github.com/sebastienrousseau/acmt001.git" python -m pip install acmt001-mcp ``<details> <summary>Using an isolated virtual environment (recommended)</summary>
python -m venv venv
source venv/bin/activate # macOS/Linux
venv\Scripts\activate # Windows
python -m pip install -U acmt001-mcp</details>
Launch the server over stdio (the default transport):
acmt001-mcpRegister it with any MCP client (e.g. Claude Desktop) by adding it to the client's configuration:
{
"mcpServers": {
"acmt001": { "command": "acmt001-mcp" }
}
}The agent can then call the tools below to validate account data and generate ISO 20022 messages on demand.
One command line, three transports:
| Command | Transport | Endpoint | Protocol revisions |
|---|---|---|---|
acmt001-mcp | stdio | the client spawns the process | 2026-07-28, 2025-11-25 |
acmt001-mcp --transport streamable-http | Streamable HTTP | http://127.0.0.1:8000/mcp | 2026-07-28 (stateless, server/discover) and 2025-11-25 (initialize, Mcp-Session-Id) on the same endpoint; responses stream as server-sent events, GET opens the server-to-client stream |
acmt001-mcp --transport sse | HTTP+SSE (2024-11-05) | http://127.0.0.1:8000/sse and /messages/ | for clients that still expect the older transport |
--host and --port change the bind address (defaults 127.0.0.1 and 8000). The HTTP transports carry no authentication of their own: bind loopback, or put the server behind a gateway you trust before binding a routable address. Every release is verified over streamable HTTP with scout in both protocol eras and over SSE with the MCP SDK client; see ADR 0001.
{
"mcpServers": {
"acmt001": { "url": "http://127.0.0.1:8000/mcp" }
}
}All tools delegate to the shared acmt001.services layer, so they behave identically to the CLI and REST API.
list_message_types — List the 34 supported acmt message typesget_required_fields — Required input fields for a message typeget_input_schema — Full input JSON Schema for a message typevalidate_records — Validate flat records against a message typevalidate_identifier — Validate an IBAN, BIC, or LEIgenerate_message — Generate a validated acmt XML messageverify_lei_online — Look an LEI up in the live GLEIF register (needs the online extra)You can invoke the tools in-process — without a transport — straight through the server instance. This mirrors what an agent receives over stdio. The runnable version of this snippet lives in examples/mcp_tools.py.

asyncio.run(main())Run it directly:
python examples/mcp_tools.pypython benches/bench_tool_dispatch.py # full run
python benches/bench_tool_dispatch.py --quick # what CI runsThe benchmark measures what an agent waits for: the dispatch floor (list_message_types, around a microsecond), the metadata lookups used to build a request, and the two batch tools side by side.
The result worth knowing is the asymmetry between those two. validate_records checks every record, so it is linear in batch size. generate_message, for a single-account message type like the default acmt.007.001.05, renders only the first record — twenty-seven of the thirty-four templates work this way. So validating a hundred records and generating from them costs roughly 260 ms of validation against 6 ms of generation, and returns one message rather than a hundred.
That is correct ISO 20022 behaviour and a real trap when batching, which is why the benchmark prints output size beside the timings: flat bytes across growing input is what tells you the rest of the batch was not rendered. See docs/benchmarks.md.
