## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - 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.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 40/100
  - Verified sse transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 272 tokens (~54/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 73/100
  - Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `relay_status` (~20 tokens)

Check whether the OrcaVault relay is online and healthy.

### `check_access` (~26 tokens)

Check if the OrcaVault house wallet is allowed to upload, and the current fee.

### `store_memory` (~122 tokens)

Store a file permanently on-chain via OrcaVault.

Provide the file as base64 in content_base64. Returns the on-chain memory id
plus a public retrieval URL. One-time cost is paid at house-wallet setup; the
relay covers all gas.

mem_type must be one of: photo, video, audio, document.

Input parameters:

- `caption` (string)
- `content_base64` (string, required)
- `mem_type` (string)
- `mime_type` (string)
- `template` (string)
- `title` (string, required)

### `get_memory_status` (~38 tokens)

Check whether a stored memory has finished writing and is ready to retrieve.

Input parameters:

- `memory_id` (integer, required)
- `version` (string)

### `get_memory` (~66 tokens)

Retrieve a stored memory. Always returns a public URL. If the file is small
(<= inline_max_mb), the bytes are also returned inline as base64.

Input parameters:

- `inline_max_mb` (number)
- `memory_id` (integer, required)
- `version` (string)

## Common questions

### What is the OrcaVault MCP server?

OrcaVault is an MCP server listed in the public MCP registry as io.github.Keiko-Dev-LCAI/orcavault-mcp. Permanent on-chain memory for AI agents on Lightchain via a one-time unlock. This page covers its hosted endpoint (https://orcavault-mcp-production.up.railway.app/sse).

### Is the OrcaVault MCP server safe to use?

OrcaVault scores 65 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 OrcaVault MCP server expose?

OrcaVault exposes 5 tools: relay_status, check_access, store_memory, get_memory_status, get_memory. Their descriptions and schemas cost roughly 272 tokens of context every time the server is loaded.

### Does the OrcaVault MCP server require authentication?

No. We connected to OrcaVault without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the OrcaVault MCP server still maintained?

OrcaVault 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.
