Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability84
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1215 tokens (~121/item across 10 items; 8 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.github.theluckystrike/dunning MCP server?
io.github.theluckystrike/dunning is a hosted endpoint at https://mcp.zovo.one/mcp/dunning, 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.

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 →
dunning_text Write a dunning letter ~214

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
statement_aging Age the open invoices ~144
Age open invoices into 0-30, 31-60, 61-90 and over 90 days past DUE date at a date, per client and currency, with the invoices themselves. Free. statements_report rolls up the whole book instead.

What is the io.github.theluckystrike/dunning MCP server?
io.github.theluckystrike/dunning is an MCP server listed in the public MCP registry as io.github.theluckystrike/dunning. Write payment chasers at three levels from the invoices that are actually overdue. This page covers its hosted endpoint (https://mcp.zovo.one/mcp/dunning).
Is the io.github.theluckystrike/dunning MCP server safe to use?
io.github.theluckystrike/dunning scores 84 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the io.github.theluckystrike/dunning MCP server expose?
io.github.theluckystrike/dunning exposes 8 tools: statement_build, statement_aging, statement_text, statement_pdf, dunning_text, and 3 more. Their descriptions and schemas cost roughly 1,138 tokens of context every time the server is loaded.
Does the io.github.theluckystrike/dunning MCP server require authentication?
Yes. io.github.theluckystrike/dunning asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the io.github.theluckystrike/dunning MCP server still maintained?
io.github.theluckystrike/dunning is still listed as active in the MCP registry. We last reached this channel on 30 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
