An MCP server that provides deterministic, high-precision business, finance, and operational calculations such as SaaS metrics, currency conversion, business days, and financial formulas, returning structured JSON results.
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.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
esbuild enables any website to send any requests to the development server and read the response

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
11/11 tools missing one or more hints — calculate_metric (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_metrics (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); currency_convert (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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
9/11 tool handlers declare input schemas (82%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/11 tool handlers wrap calls in try/catch (9%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
7/11 tools referenced in tests (64%)
Write tests that reference each tool by name so every tool has at least one test.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
