Install

As a Python library

python -m pip install pain001-mcp

Latest release: v0.0.80: a security release on the pain001 0.0.80 floor. commit_payment_batch writes only new .xml files inside its output directory (GHSA-hqw7-q8v2-pq3m).

Published packages and development branches are distinct. Test unreleased changes on this companion's feat/v<next-version> branch against the matching core branch.

Requirements

Python 3.11 or newer. CI tests 3.11–3.14 on Linux. See toolchain policy; no distro-system-Python claim is made.

Quick Start

pain001-mcp --help
pain001-mcp

The second command starts the stdio MCP server and waits for a client. Configure your client to launch pain001-mcp. Use generated help for optional HTTP/SSE transports; secure network access before exposing any listener.

The pain001-mcp ecosystem

This independently installed companion delegates payment behavior to core. Coordinated versioning does not imply branch changes have been released.

Capabilities at a glance

Ecosystem comparison

This matrix describes the repository's scope, not an independently benchmarked comparison with competitors.

See docs/COMPARISON.md for the evidence and complete matrix.

Benchmarks

CI smoke-runs benchmarks. No hardware-independent throughput or latency promise is made; use the generated run report for measurements.

See docs/BENCHMARKS.md for methodology and full results.

Features

The authoritative tool catalogue is generated from the server. It covers validation, identifiers, generation, migration, bank-report parsing, corpus access, review-only record fixes (suggest_record_fix) and the faces (list_faces, project_face). Suggestions require review; financial fields are refused, never guessed. Test unreleased tools with the matching core feature branch. In-tree core MCP is a separate smaller surface.

Configuration

Run pain001-mcp --help for transport, host and port options. Stdio is default. See the tool catalogue for request shapes rather than a copied tool count.

Examples

Run the self-checking scripts under examples/. Tests cover valid and malformed inputs and integration with the core contract.

When not to use pain001-mcp

Not a bank, settlement engine or autonomous payment approver. Review outputs before use. Transport support is not bank certification.

Development

poetry install
poetry run make check
poetry run make security
poetry run python scripts/tool_catalogue.py --check
poetry run python scripts/render_readme.py --check

Coverage is gated at 100% line and branch. See CONTRIBUTING.md and DEVELOPMENT.md. README is generated from the canonical layout and docs/readme-values.json; CI rejects drift.

Security

Treat requests as untrusted. Protect HTTP listeners and avoid real secrets in logs. Tools may read authorized input paths. Corrections never patch IBANs, BICs, amounts or currencies.

Report vulnerabilities according to SECURITY.md.

Stability guarantees

Versions advance in coordinated 0.0.1 steps with core. The maintainer opens releases; this branch does not bump versions. Contract and output changes need compatibility review. No stronger platform or stability guarantee is implied.
