How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
  • 1 of 23 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
Schema Quality & AI Usability68
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 500 tokens (~100/item across 5 items; 5 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 5 exposed · ~414 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 →

Tool Tokens
attest_completed_action ~135

Witness the OUTCOME of a consequential action AFTER it executes (phase=completed). `result` carries upstream_response_hash / outcome / fingerprint. Provide underlying_record_ref so the full compliant record (ISO 20022 / FINRA 4511 telemetry) is retrievable — DELBOY witnesses over it, it does not replace it.

No examples provided.

attest_pending_action ~144

Witness a consequential action BEFORE it executes (phase=pending). Returns a signed pre-attestation receipt. `instruction` is hashed, never stored raw. `principal` must carry a principal_id_hash (PII-minimized), not raw identity. For meaningful-oversight regimes (UK DUAA / EU Art.14 / MAS), populate policy.approval_evidence (approval_method, what_shown_hash, dwell_ms, human_edited).

Common questions

What is the delboy-mcp server?

delboy-mcp is listed in the public MCP registry as io.github.CSOAI-ORG/delboy-mcp. DELBOY companion-MCP, neutral provenance/attestation layer for agentic finance. Witness only: signs. This page covers its PyPI package (delboy-mcp).

Is the delboy-mcp server safe to use?

delboy-mcp scores 76 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. 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 delboy-mcp server expose?

delboy-mcp exposes 5 tools: attest_pending_action, attest_completed_action, attest_terminal, verify_chain, delboy_info. Their descriptions and schemas cost roughly 414 tokens of context every time the server is loaded.

Is the delboy-mcp server still maintained?

delboy-mcp is marked deprecated in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the delboy-mcp server under?

delboy-mcp declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
