## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: mnemos_store (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); notarize (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); agora_catalog (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,153 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 15, about 2,153 tokens to load them all
- tool set hash: 1c5b3d2d7d308bec5ae4b09d5939d1fe
- badge: [![protogrid quality](https://protogrid.dev/badge/com.virohanalife/mnemos.svg)](https://protogrid.dev/servers/com.virohanalife/mnemos)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (15)

- `agora_catalog`: FREE. Discover the full Agora x402 service catalog: every buyable tool, its
price in USDC on Base, and the x402 settlement parameters (network, asset, payTo).
Call this first to see what you can buy and how to pay.
- `code_review`: PAID (0.05 USDC). Review a code snippet for correctness, security, and clarity;
returns a severity-ranked findings report after payment. Returns an x402 quote.
- `embed_batch`: PAID (0.005 USDC). Text embeddings via local Jetson Ollama (nomic-embed-text,
6000-char truncation, up to 32 texts per batch). Returns an x402 quote + payment
instructions; {model, dims, vectors} is delivered after payment settles.
- `fact_verify`: PAID (0.25 USDC). Verify a factual claim and return a supported/refuted verdict
with reasoning and citations. Returns an x402 quote + payment instructions.
- `mnemos_as_of`: PAID (0.005 USDC). THE BI-TEMPORAL READ -- the thing no other memory service
on this mesh sells. Answers: "what did the store BELIEVE at `tx_time` about what
was TRUE at `valid_time`?" Use it to replay an agent's decision with only the
knowledge it had at the time (no hindsight leakage), to audit corrections, and
to distinguish "we were wrong" from "the world changed". Returns an x402 quote.
- `mnemos_get_context`: PAID (0.005 USDC). The endpoint to call right before a completion: searches
your memories, dedupes to the most-recent belief per key, budget-packs them
into `max_chars`, and returns a ready-to-paste context block plus structured
provenance. Content flagged as prompt-injection is excluded from the block.
Optionally assembled AS OF a past time. Returns an x402 quote.
- `mnemos_provision`: PAID (0.50 USDC, monthly floor). Mint your own fully isolated bi-temporal
memory namespace. Payment IS the identity -- no signup, no email: settling the
x402 quote issues a tenant key, shown exactly once. Returns an x402 quote.
- `mnemos_saas_info`: FREE. Learn how Mnemos-as-a-Service works before buying: the BI-TEMPORAL
contract (two independent time axes per memory), the tenant-isolation model,
limits, pricing, and a worked example showing four different correct answers
for one key. No payment, no tenant data. Call this first.
- `mnemos_search`: PAID (0.005 USDC). Semantic search over your CURRENT beliefs, ranked by
cosine similarity (nomic-embed-text, computed locally). Raw embedding vectors
are never returned. Returns an x402 quote; send X-TENANT-KEY once settled.
- `mnemos_store`: PAID (0.01 USDC). Store a memory in your isolated bi-temporal namespace.
Append-only: `supersedes` marks a prior belief as no longer held WITHOUT
destroying it, so it stays queryable via mnemos_as_of. `valid_from`/`valid_to`
describe when the fact is true IN THE WORLD and may be backdated; the system's
own knowledge timestamps are server-stamped and cannot be forged.
Returns an x402 quote; requires header X-TENANT-KEY once settled.
- `notarize`: PAID (0.10 USDC). Produce a tamper-evident notarization record (sha256 digest +
signed timestamp) for a piece of content. The quote preview already includes the
sha256 digest so you can verify integrity; the signed record follows payment.
- `research_brief`: PAID (0.10 USDC). Structured synthesis brief on a topic, from local model
knowledge only. This tool does NO live web research and returns NO citations --
claims are not sourced. The delivered brief carries in-band caveats stating its
knowledge cutoff and limits. If you need cited, web-researched output, that is a
different product (research-brief-pro on the HTTP rail), not this one.
Returns an x402 quote + payment instructions; the brief is delivered after settlement.
- `summarize`: PAID (0.03 USDC). Full-quality document summarization. Returns an x402 quote +
payment instructions; the summary is delivered after payment settles.
- `summarize_demo`: FREE. A working demo of the paid `summarize` tool: returns a tiny deterministic
extractive summary (first + most-salient sentences, capped ~280 chars) so agents can
verify the connector end-to-end before buying. No payment, no auth required.
- `trust_check`: PAID (0.05 USDC). Combined Trust Oracle probe: aggregate bazaar-index stats
(reachable/valid-402 counts, median latency) + a watchtower attestation for one
URL (reachable, returns_402, latency, score). Returns an x402 quote + payment
instructions; the combined result is delivered after payment settles.
