Category Design and Media
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 Security63
- 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- 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 Usability63
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1383 tokens (~172/item across 8 items; 8 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 Coverage86
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 58% 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
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.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
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail

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 →
browse_collections Browse collections ~64
List the 15 collections plus Singles, each with the number of works it holds. Ask for one by name to get its works in full. Each collection includes its curatorial capsule alongside the works it contains.
| Name | Type | Req | Description |
|---|---|---|---|
| collection | string | – | Omit to list them all |
No output schema declared.
No examples provided.
catalog_overview Catalogue overview ~40
A high-level view of the whole catalogue: totals, collections, resolutions, price range, what is available, and how much of it has been measured.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
confirm_inquiry Confirm inquiry ~97
Send an enquiry prepared with request_inquiry, once the person named has seen exactly what will be sent and agreed to be contacted. Takes the confirmation code and the same email; what is sent is exactly what was shown, and only once. It never reports success unless the message actually left.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmation_code | string | yes | The code request_inquiry returned |
| contact_email | string | yes | The same email the enquiry was prepared with |
No output schema declared.
No examples provided.
get_artwork Get artwork ~86
Retrieve one artwork in full: technical specification, availability, price, the physics measured from its master, and, when available, the curatorial capsule. Accepts the identifier or the title — and when a title belongs to more than one work, it returns them all rather than guessing.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Artwork identifier, or its name. An ambiguous name returns every candidate. |
No output schema declared.
No examples provided.
rank_artworks Rank artworks ~158
Order the catalogue by one measured axis — rhythm of change, luminance, peak brightness, colour travel, empty space, and the rest — from lowest to highest or the reverse, and read where each work sits on the catalogue's own scale. Use it for questions like "the stillest work you have" or "the brightest, in this collection". Every number comes from the master, frame by frame; nothing here is described.
| Name | Type | Req | Description |
|---|---|---|---|
| availability | string | – | – |
| collection | string | – | Restrict to one collection |
| count | integer | – | – |
| metric | string | yes | The measured axis to order by |
| order | string | – | asc = lowest first (the stillest, the darkest); desc = highest first |
No output schema declared.
No examples provided.
recommend_for_space Recommend for space ~280
Describe a space and receive the works that fit it, each with the measurement behind the suggestion and its curatorial capsule. Room light, viewing distance, screen size, attention and movement are measured; collection, resolution, orientation, colour and budget are hard limits, and a work that may be rotated counts for the other orientation. If nothing fits, it says which requirement leaves nothing instead of offering the nearest thing.
| Name | Type | Req | Description |
|---|---|---|---|
| attention | string | – | Should it accompany, or hold the eye? |
| budget_max | number | – | – |
| collection | string | – | Recommend only from this collection |
| colour | string | – | – |
| count | integer | – | – |
| distance_m | number | – | Metres from viewer to screen |
| movement | string | – | Very still, or full of life? Measured rhythm, on the catalogue scale |
| orientation | string | – | ultrawide = at least twice as wide as tall (21:9 and wider); landscape includes it |
| resolution | string | – | Only works native to this resolution label (HD, 4K, 8K, 16K…; square works carry their own, such as 2K) |
| room_light | string | – | – |
| screen_m | number | – | Screen diagonal in metres |
| space_description | string | yes | The room in your own words |
No output schema declared.
No examples provided.
request_inquiry Request inquiry ~172
Prepare an enquiry to the studio — acquisition, exhibition or press — and see exactly what would be sent. Nothing is sent at this step: the draft is held for two days, seen by nobody, and deleted unless it is confirmed. Show the details to the person named, and only if they agree to be contacted, send it with confirm_inquiry and the code this returns. Requires a way to reply and a description of the space or project.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_name | string | – | The agent sending this on behalf of a client |
| artworks_of_interest | array | – | – |
| budget_range | string | – | – |
| contact_email | string | yes | – |
| contact_name | string | yes | – |
| inquiry_type | string | – | – |
| message | string | – | – |
| space_description | string | yes | – |
No output schema declared.
No examples provided.
search_artworks Search artworks ~361
Search the catalogue of 297 moving-image works by César Yagüe by free text, collection, resolution, orientation (including ultrawide), colour measured from every frame (a basic colour counts its whole family), price, year, loop length, rotation and availability. A short page brings each work's curatorial capsule. Asking about flashes or epilepsy returns the works with measured abrupt light events.
| Name | Type | Req | Description |
|---|---|---|---|
| availability | string | – | – |
| collection | string | – | Collection name |
| colour | string | – | Dominant colour by name (gold, teal, crimson…) or hex. Measured from every frame. |
| limit | integer | – | – |
| max_price | number | – | – |
| max_seconds | number | – | Longest loop length, in seconds |
| min_price | number | – | – |
| min_seconds | number | – | Shortest loop length, in seconds |
| offset | integer | – | Skip this many results, to read the next page |
| order | string | – | – |
| orientation | string | – | ultrawide = at least twice as wide as tall (21:9 and wider); landscape includes it |
| query | string | – | Free text across titles, descriptions and curatorial notes |
| resolution | string | – | The resolution label each work shows, matched exactly: HD, 4K, 5K, 8K, 10K, 12K, 16K; square works carry their own, such as 2K or 3K. An unknown label returns the list in use. |
| rotation | string | – | Whether the work must keep its orientation or may be rotated 90 degrees |
| sort_by | string | – | – |
| year | integer | – | Year the work was created |

What is the PaKi Curator MCP server?
PaKi Curator is an MCP server listed in the public MCP registry as es.cesaryague/paki-curator. Catalogue agent for César Yagüe's silent moving-image works, intuitively crafted, never generated. This page covers its hosted endpoint (https://paki-api.elfresonero.workers.dev/mcp).
Is the PaKi Curator MCP server safe to use?
PaKi Curator scores 75 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 PaKi Curator MCP server expose?
PaKi Curator exposes 8 tools: search_artworks, get_artwork, recommend_for_space, browse_collections, catalog_overview, and 3 more. Their descriptions and schemas cost roughly 1,258 tokens of context every time the server is loaded.
Does the PaKi Curator MCP server require authentication?
No. We connected to PaKi Curator without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the PaKi Curator MCP server still maintained?
PaKi Curator is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
