ERP Upgrade & Fit-Gap Advisor (Claude plugin)

Choose, plan, cost and upgrade an ERP with sourced facts, not guesses. For French SMEs and mid-size companies evaluating or running Odoo, Microsoft Dynamics 365 Business Central, Sage 100 / X3, SAP Business One, Divalto, Cegid, Sylob or EBP — with a deep Odoo 20 upgrade module built on Odoo 20 release day (24 Sept 2026).

Every vendor fact carries its URL, check date and certainty level (official / third-party / not found). Nothing is invented: unknowns become questions for the vendor.

MCP server erp-facts

The plugin connects to a read-only MCP server, https://erp-mcp.jaikin.eu/mcp (no account needed), that serves the same sourced vendor facts so they can be updated without reinstalling: list_vendors, vendor_facts, support_deadlines, einvoicing_status, odoo_20_changes, sources_and_method. Registry name: eu.jaikin/erp-facts.

Price data

Cost and quote skills use the read-only prix-logiciel MCP server (French public procurement contracts and verified private-market figures), shared with the Software Buyer France plugin.
