# govinfo_legislation_version_lineage Return every published GovInfo text-version link for one hosted bill, including version type/code, date, immutable package identifier, package page, and official XML URL. Use this for 'show the introduced, reported, engrossed, enrolled, and law versions of H.R. 2670', 'what version codes exist for S. 1?', or to assemble a reproducible legislative-text lineage. This is version metadata, not a text diff. Coverage is 118th-Congress HR/S only. Agent View of the PolicyLayer registry record for `govinfo_legislation_version_lineage`.

Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents call govinfo_legislation_version_lineage to retrieve information from Livedatalink without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Livedatalink: ```json { "version": "1", "default": "deny", "tools": { "govinfo_legislation_version_lineage": {} } } ``` ## Other tools on Livedatalink (380) - `beneficial_owner_screen` — Destructive — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/beneficial-owner-screen.md - `bea_state_economic_profile` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bea-state-economic-profile.md - `bts_transport_border_activity_pack` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bts-transport-border-activity-pack.md - `cftc_cot_evidence_pack` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/cftc-cot-evidence-pack.md - `clinical_site_selector` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/clinical-site-selector.md - `edgar_recent_filings` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/edgar-recent-filings.md - `entity_dossier` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/entity-dossier.md - `fed_board_h15_evidence_pack` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/fed-board-h15-evidence-pack.md - `fed_board_h15_yield_curve` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/fed-board-h15-yield-curve.md - `govinfo_legislation_committee_path` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/govinfo-legislation-committee-path.md - `govinfo_legislation_evidence_pack` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/govinfo-legislation-evidence-pack.md - `patent_recent` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/patent-recent.md - `treasury_tic_official_share` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/treasury-tic-official-share.md - `trials_details` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/trials-details.md - `usda_nass_crop_evidence_pack` — Execute — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/usda-nass-crop-evidence-pack.md - `affordable_housing_refinance_evidence_pack` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/affordable-housing-refinance-evidence-pack.md - `air_quality` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/air-quality.md - `bank_health_report` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bank-health-report.md - `bea_compare_states` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bea-compare-states.md - `bea_search_state_indicators` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bea-search-state-indicators.md - `bea_state_economic_trend` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bea-state-economic-trend.md - `bls_indicator` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bls-indicator.md - `bls_series` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bls-series.md - `book_details` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/book-details.md - `book_fulltext_search` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/book-fulltext-search.md - `book_get_text` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/book-get-text.md - `book_search` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/book-search.md - `book_status` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/book-status.md - `bounce_scanner` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bounce-scanner.md - `bts_transport_border_trend` — Read — https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink/bts-transport-border-trend.md - …and 350 more: https://policylayer.com/tools/io-github-blackboxfoundry-livedatalink.md ## For agents This record is a snapshot.
