Verified pricing, hidden costs, negotiation data, and total cost of ownership for thousands of software products.
Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
Scanned 9 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The costbench MCP server exposes 8 tools across a range of capabilities. Its published description reads: "Verified pricing, hidden costs, negotiation data, and total cost of ownership for thousands of software products". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates costbench C+ — the findings are worth reviewing before you connect an agent to it. Its most notable finding was "No authorization on a public remote server". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check costbench's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add costbench to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

Full sourced pricing record for a software product: tiers, hidden costs, contract terms, market data, sentiment, negotiation tips, TCO scenarios, price history — every claim with its sources + a confi
The documented hidden/implementation/add-on costs of a product (uplifts, onboarding fees, overages), each with a sourced quote + date. The "what they don't tell you" answer.
Sourced negotiation tactics for a product with success-likelihood (how to get a discount).
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
The server accepts tool enumeration (and likely invocation) with no authentication.
