Streamable HTTP · live now

Evidence for market agents.

Give an MCP client the same point-in-time stock and crypto event graph used by the DataCedar REST API. Every tool keeps plan latency, source rights, citations, and historical cutoffs intact.

Create a key Read the protocol docs

Connect once.

Use the remote endpoint in any client that supports MCP Streamable HTTP. Omit the API key intentionally for bounded discovery, or provide an account key for your real history window and rate limits. Invalid, expired, or revoked keys fail authentication and never silently become demo access.

Point-in-time

as_of reconstructs only revisions known by the cutoff.

Rights-aware

MCP cannot retrieve source text REST would withhold.

One event graph

Tool results use the same handlers and response contracts as REST.

initialize · tools/list · tools/call

datacedar_search_events

Filter stock, crypto, macro, regulatory, and protocol events.

datacedar_get_event

Inspect one revision with citations, entities, and known-at lineage.

datacedar_search

Search rights-cleared event and source metadata.

datacedar_entity_timeline

Reconstruct the event history of one resolved asset or entity.

datacedar_get_document

Read display-safe evidence metadata without bypassing source rights.

datacedar_get_cluster

Inspect related event revisions and source conflicts.

datacedar_trends

Aggregate event activity by time and classification.

datacedar_coverage

Check source freshness, universe, latency, and rights state.

datacedar_sources

Read the current enabled source-policy registry.

Suggested agent sequence

Discover with datacedar_search_events or datacedar_search, inspect the exact evidence with datacedar_get_event, then check datacedar_coverage before treating an empty result as “nothing happened.”
