Overview

AI-generated overview

Remote MCP server for finding, sampling and querying official US public datasets, with provenance, freshness and paid query/aggregation tools.

What you can do
  • Search and browse official data catalogs: find datasets, list covered official sources, search discovered datasets, and check coverage and import status
  • Inspect query-ready datasets: list published snapshots with row counts, freshness and provenance
  • Evaluate data for free: sample a dataset or pull a free US Federal Register briefing with aggregates
  • Request materialization of a discovered dataset and poll the job until sample and query URLs are ready
  • Run paid read-only queries and grouped aggregations over published snapshots, or query Federal Register records by date or document type
  • Record demand for missing datasets or capabilities, and request paid access via Stripe Checkout
When to use it
Useful when an assistant needs official US federal, state, city, police or education data and must first discover which dataset fits, check freshness and provenance, and preview rows before committing to a paid query. The free sampling and Federal Register tools also let you evaluate the service before paying.
Requirements
Remote streamable HTTP endpoint; no authentication, environment variables or headers declared. Paid tools require a Stripe Checkout purchase ($5 pass or $5/month subscription) and a claim URL. Network access to the provider is required.
Before you install
Several tools cost money: query_imported_dataset, aggregate_imported_dataset and query_us_federal_register are paid, and request_paid_access creates a Stripe Checkout, so confirm human approval before spending. request_capability and request_paid_access change state on the provider side. Queries and requests are sent to a third-party service, and coverage is limited to the sources it has imported.

Installation

In SourceWeft

  1. Open Free Official Data Samples, Provenance, Aggregations & Insights in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.cazimedia.agentnative%2Fofficial-provenance-aggregations-insights-free-samples-open-data/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

14

search_public_datasets

Search public datasets

Use this free tool first when an agent needs official US federal data but does not yet know the dataset ID. Searches normalized catalog metadata and returns matching datasets with provenance; it does not query dataset rows.

Parametersqueryrequired

request_dataset_materialization

Make a discovered dataset query-ready

Queue a discovered official dataset for prioritized detached ingestion. This free idempotent operation returns a durable job ID; poll get_materialization_status until it supplies sample and query URLs.

Parametersdiscovered_dataset_idrequired

get_materialization_status

Check dataset materialization

Poll a durable materialization job. A complete result includes the query-ready dataset ID plus free sample and paid query URLs.

Parametersmaterialization_idrequired

list_official_sources

List official government sources

Use this free tool to inspect which federal, state, city, police, education, and other official source scopes AgentNative currently covers. Returns each source's importer, discovery state, and materialized coverage; it does not return dataset rows.

Takes no parameters.

search_discovered_datasets

Search discovered government datasets

Use this free tool to find datasets across all discovered official sources, including candidates not yet queryable. Returns catalog matches and materialization state; use list_imported_datasets when only query-ready data is acceptable.

Parameterslimitquerysource_id

get_coverage_status

Get public-data coverage status

Use this free operational tool to decide whether available public-data coverage is sufficient or whether to request a missing capability. Returns discovery, materialization, queryable-row, queue, failure, and freshness counts.

Takes no parameters.

list_imported_datasets

List queryable official datasets

Use this free tool when an agent needs only datasets that can be sampled or queried now. Returns fully published warehouse snapshots with dataset IDs, row counts, freshness, and provenance.

Takes no parameters.

sample_imported_dataset

Sample an official dataset for free

Use this free tool to evaluate a query-ready official dataset before paying. Returns three normalized rows, deterministic summaries, freshness, and provenance; use query_imported_dataset only after the sample proves useful.

Parametersdataset_idrequired

sample_us_federal_register

Get a free Federal Register briefing

Use this free no-auth tool for current US regulatory activity or to evaluate AgentNative before paying. Returns three Federal Register records plus deterministic aggregates over the latest 25 documents, direct record URLs, provenance, and rate-limit status.

Takes no parameters.

query_imported_dataset

Query an imported official dataset

Use this paid read-only tool after sample_imported_dataset confirms the data is suitable. Returns up to 100 normalized rows from a published snapshot with bounded pagination, one exact-match filter, freshness, and provenance.

Parameterstopskipdataset_idrequiredfilter_fieldfilter_value

aggregate_imported_dataset

Aggregate an official dataset

Use this paid read-only tool for deterministic grouped statistics instead of downloading rows and calculating locally. Returns bounded count, sum, average, minimum, or maximum groups with dataset provenance.

Parameterstopfieldmetricgroup_byrequireddataset_idrequired

request_capability

Request a missing data capability

Use this state-changing tool only when existing discovery and coverage tools cannot satisfy the task. Records demand for a missing dataset, aggregation, insight, filter, freshness level, or export; repeated requests increase autonomous build priority.

Parametersdatasetrequiredcapabilityrequiredsource_urlexample_query

request_paid_access

Create a Stripe access checkout

Use this state-changing tool only after free samples demonstrate value and the human owner approves payment. Creates a Stripe Checkout plus one-time claim URL; choose the $5 pass for research or $5/month subscription for recurring workflows.

Parametersplan

query_us_federal_register

Query the US Federal Register

Use this paid read-only tool when the free Federal Register briefing is insufficient. Returns up to 100 normalized official records filtered by date or document type, with deterministic provenance and direct source URLs.
