Schema Quality & AI Usability75
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1705 tokens (~142/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the dev.cz-agents/dd MCP server?

dev.cz-agents/dd is a hosted endpoint at https://dd.cz-agents.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 12 exposed · ~1,392 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

EU Due-Diligence report for an international company. Input: 20-char LEI code, or company name + optional country.

Note: GLEIF covers mid/large firms with LEI — SMEs may not be found. Pro Compliance tier or higher.

NameTypeReqDescription

get_owners ~118

Look up direct and upstream Czech VR owners for a company by real active shareholding roles (spolecnik/akcionar) and company-to-company member_ico edges. Free anonymous tool.

get_risk_timeline ~114

Build a chronologically sorted lifecycle timeline for a Czech company — basic events include company formation, statutory appointments, active insolvency, sanctions matches, VAT reliability flips. Returns events[] with riskScore 0-100. Pro Compliance tier or higher.

No examples provided.

get_statutory_chain ~161

Surname-based heuristic walk through statutory bodies of related Czech companies. Best for shell-company unwinding in small s.r.o. with RARE surnames. NOT a true UBO source — for actual beneficial ownership use the ESM (evidence skutečných majitelů, separate registry, future @czagents/esm). For boards of large public companies with common Czech surnames (Novák, Zima, Kolář…) results are noisy by design; the tool auto-skips persons whose surname matches >50 companies with a SURNAME_TOO_COMMON note.

NameTypeReqDescription
icostringyesCzech IČO — 7 or 8 digits.
max_depthintegerMax recursion depth (default 3, hard cap 5).

No output schema declared.

No examples provided.

person_companies ~105

Look up Czech VR companies connected to a person by exact registry person_id -> roles -> companies joins. Free anonymous tool. Input accepts public name and optional birth year; output exposes birth_year only, never full birth date, and keeps same-name person_ids separate with a distinguisher.

No output schema declared.

Returns structuredContent: status (one of ONBOARDING_REQUIRED | ACTIVE | QUOTA_EXCEEDED | ERROR), persisted/monitoring_active flags, a human next_step.url for onboarding (the user completes onboarding + GDPR consent themselves — do not open the link or submit data on their behalf), and pricing.

What tools does the dev.cz-agents/dd MCP server expose?

dev.cz-agents/dd exposes 12 tools: person_companies, get_owners, get_dd_report, watch_entity, get_risk_score, and 7 more. Their descriptions and schemas cost roughly 1,392 tokens of context every time the server is loaded.

Does the dev.cz-agents/dd MCP server require authentication?

No. We connected to dev.cz-agents/dd without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the dev.cz-agents/dd MCP server still maintained?

dev.cz-agents/dd is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
