An MCP server that acts as a secure, multi-tenant proxy to the InvoiceShelf API, enabling AI assistants to manage invoices, estimates, customers, payments, expenses, and more with 109 tools and TOON compression for efficient token usage.
Limited view. Automated analysis covers part of this stack. Findings reflect what we verified. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.
Limited view: static analysis for Python is partially covered.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
ALLOW_ALL_AGGREGATENo When true, aggregate listing tools honor the include_all_fields parameter. When false (default), the parameter is silently forced to False for aggregate list operations.IS_STATEFULNo When true, uses stateful Streamable HTTP with session tracking. When false (default), uses stateless mode.INVOICESHELF_BASE_URLYes Docker-internal URL of the InvoiceShelf APIMCP_SERVER_PORTYes Port number the MCP server listens onINVOICESHELF_PUBLIC_URLNo Public-facing URL to replace internal Docker URLs in responses. Defaults to INVOICESHELF_BASE_URL if not set.Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
109/109 tools missing one or more hints — check_server_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_dashboard (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_bootstrap (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +106 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
105/109 tool handlers declare input schemas (96%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/109 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
