Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account CSOAI-ORG for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Local MCP server that lets an assistant check maritime compliance: MARPOL Annex VI sulfur limits, EU ETS, CII/EEXI ratings, IMDG, bunker fuel, ballast water…

What you can do: Check MARPOL Annex VI sulfur caps (0.5% global, 0.1% in ECAs) and EU ETS maritime obligations
Assess carbon intensity (CII A-E) and EEXI efficiency ratings
Review IMDG dangerous goods handling, including Class 9 lithium batteries
Compare bunker fuel test results against the BDN for sulfur, NOx and PM
Check ballast water management against the D-2 standard
Assemble a Port State Control inspection pack for Paris MoU / Tokyo MoU
When to use it: Useful for shipping operators, fleet managers and compliance staff who want an assistant to walk through MARPOL, EU ETS, CII/EEXI, IMDG, bunker and ballast water questions, or to prepare for a Port State Control inspection.
Requirements: Runs locally over stdio as a Python package (pip install, or uvx). No authentication, environment variables or headers are declared. Desktop MCP client only; not web-executable.

Before you install

Outputs are compliance guidance, not a substitute for official verification; the README cites specific regulatory thresholds and penalties that should be confirmed against current rules. The README also lists paid tiers, so some features may be gated. No credentials are requested.

Installation

In SourceWeft

Open Meok Imo Marpol Marine Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

meok-imo-marpol-marine-mcp

IMO MARPOL + marine fuel + container ship compliance MCP. MARPOL Annex VI, EU ETS maritime, CII, EEXI, IMDG, bunker fuel, ballast water, Port State Control inspection prep. By MEOK AI Labs.

Why this exists

MEOK started with road haulage. Maritime is the next vertical — short-sea operators (RoRo car carriers, Channel freight), container shipping, and the marine fuel cliff for net-zero. 2026 is the year the bills come due: EU ETS maritime is biting, CII/EEXI ratings are public, and the 2030 GHG step-change is closer than most fleet managers think.

Real cliffs this MCP exists to help operators clear:

MARPOL Annex VI 0.5% sulfur cap (global, Jan 2020) + 0.1% in ECAs (North Sea, Baltic, North America). Fines up to USD 250k + vessel detention by Port State Control.
EU ETS maritime (Jan 2024) — 50% of intra-EU + 100% of intra-EU voyages carbon-priced. 2026 ramp: 70% of allowances surrendered (vs 40% in 2024).
CII annual rating (since Jan 2023) — A/B/C/D/E. Three consecutive D or one E = corrective action plan required.
IMDG Code — Class 9 lithium batteries on container ships (Felicity Ace 2022, Fremantle Highway 2023 — 4,000+ vehicles lost combined).
IMO Ballast Water Management Convention (2017) — D-2 standard rollout completing 2024-2025.
Port State Control detention rates: Paris MoU 3.4% (2024), Tokyo MoU 3.1%. Each detention = 24-72h vessel delay = USD 30-100k.

Configuration

Add to your claude_desktop_config.json (Claude Desktop) or your MCP client config:

json

{  "mcpServers": {    "meok-imo-marpol-marine-mcp": {      "command": "uvx",      "args": ["meok-imo-marpol-marine-mcp"]    }  }}

{  "mcpServers": {    "meok-imo-marpol-marine-mcp": {      "command": "uvx",      "args": ["meok-imo-marpol-marine-mcp"]    }  }}

Or: pip install meok-imo-marpol-marine-mcp then run the meok-imo-marpol-marine-mcp command (stdio transport).

Examples

Once configured, ask your assistant, for example:

"Use check_marpol_annex_compliance to …"
"Use check_eu_ets_maritime to …"
"Use check_imo_ccc_carbon_intensity to …"
