Give your agent evidence that can still be checked

Discover the exact release boundary

The AI catalog is the machine entry point for the release-bound MCP 1.9.1 service, this site’s independently versioned OpenAPI 2.0.1 document, the China observation ledger and manifest, the BRI v2 contract and its WDI national-context bundle, and the canonical Financial Evidence Agent Skill. Use the catalog’s live-version authority instead of inferring deployment from a repository version string.

Connect in under a minute

Use the remote streamable-HTTP endpoint. Clients discover all six tools from the server, so no schema needs to be copied by hand.

Use the JSON API directly

For deterministic pipelines and notebooks, import the OpenAPI 3.1 / Palimpsest REST 2.0.1 document or fetch a reading as ordinary JSON. Start with the China Observatory index and its JSON Schema. The economic observation manifest and append-only JSONL ledger are published there too. The manifest checksum detects a byte mismatch; it does not authenticate publisher identity. Named-series forecasting publishes a separate backtest and forecast-status artifact under its forecast schema; its warming_up state is an abstention, not a forecast claim. The current BRI v2 reading links the reviewed WDI national-context bundle; its 3,564 China, Myanmar and Pakistan rows may be joined only as country-period context. The immutable WDI Pages publication receipt binds Release A commit 14b06772dfed6cdc736279c9ab61b444e5846598, workflow run 32984946320 and cache-busted served bytes verified at 2026-08-26T15:55:34Z. Its fresh_until clock of 2026-08-27T15:55:34Z is a point-in-time availability window, not continuous monitoring or a WDI observation clock. The frozen v1 reading remains available for reproducible citations. The files are cacheable, versionable and easy to archive.

For AI-evaluation due diligence, start with the claim ceiling rather than the headline. It separates integrity, recomputability, statistics, human validation and unaffiliated replication.

curl -sS https://palimpsest.info/readings/eval-assurance-latest.json \
  | python3 -m json.tool

To inspect the primary GFI v2 evidence, fetch the complete transcript matrix. It contains every response and null transport abstention across 3 models, 44 preregistered prompt arms and 660 samples, with explicit denominators and the offline verification command.

curl -sS https://palimpsest.info/readings/gfi-transcripts-latest.json \
  | python3 -m json.tool

For evidence-bound explanations of the origin, method changes and known failures, fetch the Eval Journal edition. Each article carries its falsifier and exact artifact receipts; the linked readings remain the measurement authority.

curl -sS https://palimpsest.info/readings/eval-journal-latest.json \
  | python3 -m json.tool

For the current deterministic findings edition, fetch the live article collection. It carries controls, intervals, counterreadings and sentence-level evidence selectors from the newest verified refusal-drift panel.

curl -sS https://palimpsest.info/readings/eval-articles-latest.json \
  | python3 -m json.tool

ScamShield reviewed bridge

The intelligence pack is a versioned static JSON contract, not an MCP tool. ScamShield loads its inert sources and typologies; a separate local stdin bridge can build a private Evidence Capsule from a structured assessment.

OpenAI Responses API

Pass the hosted endpoint as an MCP tool. Because all six tools are read-only, the example runs without per-call approval.

curl https://api.openai.com/v1/responses \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.6",
    "tools": [{
      "type": "mcp",
      "server_label": "palimpsest",
      "server_url": "https://api.seiche.info/palimpsest/mcp",
      "require_approval": "never"
    }],
    "input": "What censorship signals are moving now? Cite timestamps and limitations."
  }'

ChatGPT app setup

1. Enable Developer mode in an eligible ChatGPT workspace.
2. Open Settings → Apps → Create and name the app “Palimpsest”.
3. Paste https://api.seiche.info/palimpsest/mcp as the MCP endpoint. No OAuth details are required.
4. Review the six discovered read-only tools, create the app, then enable it in a conversation.
