osiris@0.1.2
VERIFIED· not startedPublisher claims: "A standard, local-first MCP server that lets AI agents carry a sealed, hash-verified task manifest across turns so state drift, loops, and duplicate actions are caught before they cost tokens. It also externalizes bulky payloads into content-addressed references that can be filtered server-side and rehydrated losslessly, keeping cached prompt prefixes intact and cutting context cost." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Not started: dependency install failed; the server itself was not observed.- Tested
- the dependency install step · every file read, file written and host contacted by what ran
- Not tested
- server startup · the tool list · tool behavior
What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names python.org, astral.sh as well as its own vendor. The guard injects OSIRIS_BYSTANDER_BELOW_TOKENS, OSIRIS_COMPACT_BELOW_TOKENS, OSIRIS_DASHBOARD_TOKEN, OSIRIS_EXTERNALIZE_MIN_TOKENS, OSIRIS_FULL_PAYLOAD_TOKENS, OSIRIS_MANIFEST_MIN_TOKENS, OSIRIS_PRUNE_THRESHOLD_TOKENS, OSIRIS_SCHEMA_ACCESS_TOKENS only into requests to the host you bind (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-11 and scored it 85/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
