MCP + CLI
One installation. 25+ federal data sources. Any AI client.
Heimdall Core is the data layer. You keep your own Claude (or Cursor, or Cline) and plug Heimdall in. Same tools delivered two ways — the MCP server for in-conversation queries, the CLI for scripts and pipelines.
What's inside
MCP server
Remote SSE gateway at api.heimdallgov.com/mcp/sse. Add it to your Claude Desktop config once, and every Claude session gets 23 Heimdall tools (findings search, RAG document search, sentinel alerts, risk heatmap, and more).
Python CLI
pip install heimdallgov. Typer-based, rich-formatted tables. Scriptable — plug Heimdall queries into cron jobs, CI pipelines, or one-off shell scripts.
25+ federal data sources
SAM.gov, USASpending, FPDS, Grants.gov, FAC, GAO, Oversight.gov, 70+ OIG sites, Federal Register, Regulations.gov, Congress.gov, OMB budget — all normalized and cross-referenced.
RAG search across 5,470+ reports
Every GAO and OIG report from 2023-2026 is chunked, embedded with Voyage 3 Lite, and searchable with page-level citations. Ask a question, get passages back with source PDFs and page numbers.
Entity-resolved data
872,793 entities with 1M+ aliases. "Booz Allen Hamilton" in USASpending and "Booz Allen" in an IG report resolve to the same UEI — queries land clean hits.
10,000 tool calls / month
Generous enough that most users never hit the limit. Overage is $0.001/call. Transparent — see exact usage at /v1/usage/summary any time.
Your Claude does the thinking
Heimdall never pays for AI inference. Your Claude subscription handles synthesis; Heimdall returns clean, structured data and cited chunks. Your $20/month Claude + our $9/month data = full intelligence stack for $29.
Evidence-traceable outputs
Every result links back to source PDFs with SHA-256 hashes and page numbers. Claude's answers stay grounded (99% grounding rate measured) instead of hallucinating.
What you can do with it
Ask any federal question in natural language
"What IG findings hit DOT over the last year related to cybersecurity?" "What contracts is Booz Allen winning in the FY2025 DHS budget?" Claude queries the Heimdall tools, you get cited answers.
Replace manual research workflows
Stop clicking through SAM.gov, USASpending, Oversight.gov, and FAC in separate tabs. One Claude conversation does the cross-referencing for you.
Script routine market scans
heimdall findings search cybersecurity --limit 25 --format json | jq ... Pipe Heimdall data into your own analytics. Automate a weekly digest to your inbox.
Extend Claude's context cheaply
Instead of stuffing 100-page PDFs into a Claude context window (expensive), let Heimdall retrieve the 3 paragraphs that matter and pass those to Claude. Faster answers, lower token cost.
