02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package pathmark - unscoped; check the name against the project README before installing

registry namespace io.github.hacksurvivor is GitHub-verified and matches the repo owner

03 · What Pathmark can do

What it does

Carry intent across agents without turning stale code facts into hidden memory.

From the project's README.

What you can build

With this server connected, an agent can save raw searchable evidence. Raw evidence is not treated as durable approved intent, search memories and conclusions, read a bounded chronological audit trail for one session: prompts, exact injected memory IDs, redacted tool inputs/results, and answers, and read compact context for a task or question.

Capability map

Tools grouped from the project's README - what Pathmark lets an agent do.

read & search

6 tools - e.g. Search memories and conclusions.; Return compact context for a task or question.; List approved saved conclusions.

search_memory · get_context · list_conclusions · list_pending_conclusions · get_memory_snapshot · get_config

Remember

1 tool - e.g. Save raw searchable evidence. Raw evidence is not treated as durable approved intent.

remember

create & write

1 tool - e.g. Propose a higher-signal durable conclusion or preference. Approval is required by default before recall.

create_conclusion

Recall

1 tool - e.g. Transparent recall: returns context plus the exact memory IDs, timestamps, sources, matches, tags, and previews used. Accepts optional tags, exact ids, and comp

recall_memory

Session

1 tool - e.g. Return a bounded chronological audit trail for one session: prompts, exact injected memory IDs, redacted tool inputs/results, and answers.

session_trace

Rate

1 tool - e.g. Label exact IDs from a chat / ask_memory recall as relevant or irrelevant so audit precision is measured.

rate_recall

Approve

1 tool - e.g. Atomically approve a proposal, optionally correcting text/tags and recording the reviewer.

approve_conclusion

Reject

1 tool - e.g. Retain a rejected proposal in the audit trail while permanently excluding it from recall.

What can Pathmark do?

With this server connected, an agent can save raw searchable evidence. Raw evidence is not treated as durable approved intent, search memories and conclusions, read a bounded chronological audit trail for one session: prompts, exact injected memory IDs, redacted tool inputs/results, and answers, and read compact context for a task or question.

How do I install Pathmark?

Run `npx -y pathmark`. The README documents 8 environment variables (PATHMARK_STORE_DIR, PATHMARK_SYNTHESIS_PROVIDER, PATHMARK_CHAT_COMMAND…) to set first. Set PATHMARK_STORE_DIR, PATHMARK_SYNTHESIS_PROVIDER, PATHMARK_CHAT_COMMAND, PATHMARK_OPENAI_BASE_URL, PATHMARK_OPENAI_API_KEY, PATHMARK_OPENAI_MODEL, PATHMARK_EXPORT_KEY before connecting. PATHMARK_CODEX_MODEL is optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Pathmark run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
