search_tenders

PAID ($0.01 USDC on Base per call via x402). Full-text and structured search over German public procurement notices (CPV, NUTS, deadline, buyer type, value). This remote server cannot pay on your behalf: the tool returns the exact HTTP URL and payment requirements; use the local MCP server (npx -y g…

get_tender

PAID ($0.002 USDC on Base per call via x402). One notice by UUID with lots, deadlines, links and winners. Returns the HTTP URL and payment requirements; pay via the local MCP server or an x402 HTTP client.

sample_tenders

FREE. The 5 most recent German public calls for tenders (compact fields) from oeffentlichevergabe.de, optionally filtered by one CPV code or prefix. Data: CC0, personal contact data removed.

tender_stats

FREE. Imported notices per publication day for the last 30 days, split by kind.

describe_api

FREE. Endpoints, prices, x402 payment details (USDC on Base), data source and licence, provider and legal notice, how to use the paid tools.

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

All four hints declared on every tool

5/5 tools missing one or more hints — search_tenders (missing: destructiveHint, idempotentHint, openWorldHint); get_tender (missing: destructiveHint, idempotentHint, openWorldHint); sample_tenders (missing: destructiveHint, idempotentHint, openWorldHint), +2 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.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
