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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability59
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1128 tokens (~282/item across 4 items; 4 tools + 0 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 Management60
- Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage97
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 92% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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

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 →
build_insurance_requirements Build contract insurance requirements ~596
Recommends the insurance a general contractor should require of a subcontractor, or a property manager or HOA of a vendor: general liability, auto, umbrella and workers' comp limits, additional insured, waiver of subrogation and primary/non-contributory wording, scaled to the trade's risk and the contract size. Returns the reasoning for each limit, contract-ready exhibit text, and a requirements object that check_certificate accepts.
| Name | Type | Req | Description |
|---|---|---|---|
| cancellationNoticeDays | integer | – | Days of written notice before cancellation. 0 = as the policy provides. |
| context | string | yes | "gc" = a contractor hiring a subcontractor; "property" = a property manager or HOA hiring a service vendor. |
| contractSize | string | yes | Contract value band. For "gc": under-50k, 50k-250k, 250k-1m, over-1m. For "property": under-10k, 10k-50k, 50k-250k, over-250k. A band from the other context is mapped to the smallest valid one. |
| hasEmployees | boolean | – | false for a sole proprietor with no employees: workers' comp is replaced by a signed exemption declaration. |
| overrides | object | – | Optional dollar limits that replace the recommended ones, for lines that are already required. |
| trade | string | yes | The vendor's trade, and the contexts it is offered in: "general" = General / multi-trade (gc); "carpentry" = Carpentry / framing (gc); "concrete" = Concrete / masonry (gc); "drywall" = Drywall / plas… |
| usesVehicles | boolean | – | Drives to or around the site. false drops commercial auto. |

check_certificate Check a certificate of insurance ~290
Checks a certificate of insurance (ACORD 25) against insurance requirements with CertifiKit's deterministic rules engine: coverage present, limits at or above the minimums, policies not expired or expiring too soon, and the required endorsements. Read the certificate yourself and pass what it shows; the verdict (pass, fail or needs_review) and a plain-English reason per requirement come from fixed rules, not a model. Anything unreported, unreadable or below 0.7 confidence is routed to needs_review, never silently passed. Use preset or the requirements object from build_insurance_requirements.
| Name | Type | Req | Description |
|---|---|---|---|
| asOf | string | – | Date to check expiry against, yyyy-mm-dd. Defaults to today. |
| certificate | object | yes | What the certificate shows. Report only what is printed; do not infer. Leave out rows the certificate does not have. |
| preset | string | – | "standard-subcontractor" = Typical GC requirements for a trade sub: GL $1M/$2M, auto $1M, workers' comp $1M, additional insured + waiver of subrogation. "property-vendor" = Common requirements for se… |
| requirements | object | – | Custom requirements, e.g. the requirements object returned by build_insurance_requirements. Takes precedence over preset. |
No output schema declared.
No examples provided.
find_coi_guides Find certificate of insurance guides ~93
Searches CertifiKit's plain-English guides on certificates of insurance: reading an ACORD 25, additional insured endorsements (CG 20 10), waiver of subrogation, subcontractor and HOA vendor insurance requirements, COI tracking. Returns titles, summaries and links to cite. Leave query empty to list the newest.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| query | string | – | Topic or question. |
No output schema declared.
No examples provided.
list_requirement_presets List requirement presets ~42
The ready-made insurance requirement sets check_certificate accepts as preset: a standard construction subcontractor and a property / HOA vendor, with every limit and endorsement spelled out.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
How do I install the CertifiKit COI tools MCP server?
CertifiKit COI tools is a hosted endpoint at https://certifikit.ai/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.
