Portable trust receipts for agent workflows. Signed, chained, verifiable.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
treeship_session_statusShow the active Treeship session: id, name, started_at, event count, and the current actor. Returns JSON.
treeship_session_eventAppend a structured event to the active Treeship session. Use type=agent.note for free-form notes the agent wants on the receipt timeline; put the note in meta.text.
treeship_attest_actionSign a Treeship action artifact recording that the agent is about to do something. Returns the artifact id as JSON.
treeship_verifyVerify a Treeship artifact id and its parent chain. Returns the verification result.
treeship_session_reportPublish the latest closed session as a shareable report. When summary is provided, close the active session with that summary first.
treeship_mint_challengeMint a 128-bit challenge nonce to hand to another agent. YOU are the receiver: run this before accepting any work from another agent, then require that agent to answer THIS nonce with treeship_present. Never accept a nonce the other party generated — a nonce they chose can be pre-signed, which prove…
treeship_presentPackage this agent’s card, certificate chain, known revocations, and a Merkle staple into a presentation file, answering a challenge nonce the counterparty minted. Use when another agent or a human asks you to prove who you are. Presenting without a challenge is not proof of identity and this tool r…
treeship_verify_presentationVerify a counterparty presentation against YOUR pinned trust roots, fully offline. Run this BEFORE doing work another agent asked for, and do not proceed if it fails. Read the structured fields rather than the verdict line: an unpinned issuer and a replayed nonce both print CHALLENGE FAILED, but key…
treeship_attest_handoffSign a record that custody of some artifacts passed from one agent to another. Pass the presentation file you verified with treeship_verify_presentation and the nonce you minted, and the CLI re-checks it and signs custody: live bound to that file and nonce — or refuses to write anything if it no lon…
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
9/9 tools missing one or more hints — treeship_session_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); treeship_session_event (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); treeship_attest_action (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — treeship_session_status (line 33: exec(TREESHIP_BIN, args, { timeout: TIMEOUT_MS }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool test coverage
Only 0/9 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
4 calls in production code run through a shell (src/server.ts:33, src/attest.ts:64, src/attest.ts:95)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Domain consistency
npm scope @treeship doesn't match GitHub owner zerkerlabs
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
Tool description accuracy
treeship_session_status: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
