Available components
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 native-build step with no shell scripting around it. View diagnostics → Pass
- 1 of 23 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
- Repository check failed: no source repository is declared. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (Apache-2.0).Pass
- Actively maintained (last published 4 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
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 Management47
- Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the delboy-mcp server?
delboy-mcp runs locally as a PyPI package, launched with uvx delboy-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

- 19 Sept 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 40 to 43. That category is still filling its 30-day observation window: 12 days of observed history at the previous scan, 13 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
attest_completed_action 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.

Structured output declared, but exposes no named fields.
No examples provided.
attest_pending_action 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).

Structured output declared, but exposes no named fields.
No examples provided.
attest_terminal Attest Terminal ~83
Kill-switch / guardrail-halt record (phase=terminal). Written when a guardrail fails and the action is blocked. Records why and seals it.

|---|---|---|---|
| agent | object | yes | – |

Structured output declared, but exposes no named fields.

verify_chain Verify Chain ~24
Verify the full attestation chain (link integrity + every Ed25519 signature).

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 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 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 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.
