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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability73
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 797 tokens (~159/item across 5 items; 5 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 Management100
- 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 5 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
How do I install the Sponsor Finder MCP server?
Sponsor Finder is a hosted endpoint at https://mcp.sponsorfinder.io/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.

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.

check_salary_threshold Skilled Worker Salary Check ~299
Check a UK job offer against the Skilled Worker visa salary thresholds and occupation going rates. Takes a job title (or SOC 2020 code), the annual salary, and the contracted weekly hours — hours matter, because going rates pro-rate. Returns a three-state verdict: eligible, not_eligible, or uncertain with the reason. Covers the standard Skilled Worker route only (not Health & Care or Global Business Mobility).
| Name | Type | Req | Description |
|---|---|---|---|
| job_title | string | yes | The job title, e.g. "software developer" or "civil engineer". A 4-digit SOC 2020 code also works. |
| new_entrant | boolean | – | Applicant is a new entrant at the start of their career. |
| on_immigration_salary_list | boolean | – | The job is on the Immigration Salary List (asserted by the user — the list itself is not modelled). |
| phd_relevant | boolean | – | Applicant holds a PhD in a subject relevant to the job. |
| phd_stem | boolean | – | Applicant holds a PhD in a STEM subject relevant to the job. |
| salary_gbp_per_year | number | yes | Gross annual salary of the offer, in pounds. Decimals allowed. |
| weekly_hours | number | yes | Contracted weekly hours. Required: going rates are published for a 37.5-hour week and pro-rate with actual hours, so the same salary can pass at 37.5 hours and fail at 45. |

check_sponsor_license Check Sponsorship Licence ~212
Check whether a company holds a UK or Netherlands work-visa sponsorship licence. The register lists official registered legal entity names, not brand, product, or trading names. If the user provides a brand name, product name, or website, first determine the company's registered legal name (via web search, the company's own website, or the relevant companies register) and pass that. Tolerates minor typos but not brand-vs-legal-name mismatches. Returns licence routes, ratings, locations and register dates. If results are ambiguous or none are found, refine the legal name and try again. For exploring or filtering many companies, use search_sponsors instead.
| Name | Type | Req | Description |
|---|---|---|---|
| company_name | string | yes | The company's registered legal entity name — not a brand, product, or trading name, and not a URL. If the user gave a brand name or website, resolve the official registered legal name first, then pas… |
| country | string | – | Which register to check: uk, nl, or both |
No output schema declared.
No examples provided.
get_register_info About the Sponsor Registers ~42
Register statistics, data freshness, and terminology for the UK and Netherlands sponsor registers. Use this to explain what a licence, route, rating, or sponsor type means.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_sponsor_details Get Sponsor Details ~101
Full record for one organization by id: routes, ratings, locations and register dates (UK), or sponsor type and KvK number (NL). Optionally include register change history.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | Which register the id belongs to |
| include_history | boolean | – | Also include register change history (ADDED / REMOVED / REACTIVATED events) |
| org_id | integer | yes | Organization id (from a search or check result) |
No output schema declared.
No examples provided.
search_sponsors Search Sponsor Register ~143
Exploratory list search of the sponsor register with optional filters (city/route for UK, sponsor type for NL). Returns a compact list with a total count. For checking one specific company, prefer check_sponsor_license.
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | – | Filter by city (UK only) |
| country | string | – | Which register to search |
| limit | integer | – | Max results (1–20) |
| query | string | – | Substring to match in the company name |
| route | string | – | Filter by visa route, e.g. "Skilled Worker" (UK only) |
| sponsor_type | string | – | Filter by sponsor type (NL only) |
No output schema declared.
