Search 1M+ open-access documents — papers, standards, textbooks, and case law — right from your terminal or your AI agent.
conceptio-search is a CLI and Model Context Protocol (MCP) server for the Conceptio Open Knowledge Archive — 1M+ open-access documents from 500+ living sources, indexed daily. Every source is open access or public domain. The CLI authenticates with an API key: sign in once, save the key, search from anywhere.
~/.conceptio/config.json.pip install conceptio-search
Requires Python 3.8+. (Checked, not just claimed: the suite parses every source file at the declared floor's grammar, so the promise cannot rot silently.)
The console script is conceptio; python -m conceptio_cli is the same entry point for a virtualenv that was never activated.
The CLI needs an API key before it can search:
conceptio auth ckey_live_...
Get the key by signing in at conceptio.app and creating one on your profile (Free, Dev, Pro, or Enterprise). The key is stored in ~/.conceptio/config.json and sent as X-Api-Key with every request. conceptio quota reports your tier at any time. Every command below assumes this step is done — without a key the CLI refuses to run and tells you exactly this.

Tip: conceptio download 2844 saves the PDF, conceptio cite 2844 exports a citation.
Query words are highlighted in gold in the title column. The PDF column shows [x] when a direct PDF link is available; [ ] rows still surface the source URL via conceptio info .
The CLI understands the same directives as the Conceptio web app — they are stripped from the query and applied as real filters:
| Directive | Example | Effect |
|---|---|---|
source: / src: | source:nist | Restrict to one or more sources (source:nist source:owasp) |
lang: / language: | lang:it | Restrict to a language (ISO code) |
category: / cat: | cat:"Law & Regulation" | Restrict to a category tab |
--license commercial-ok | --license commercial-ok | Keep only sources whose catalog metadata explicitly permits commercial use; this is a conservative filter, not a redistribution grant. |
Directives can be combined freely: conceptio search "cat:\"Computer Science & Tech\" source:nist lattice cryptography".
conceptio resolve recognises several identifier shapes and returns a typed response (kind: rfc | doi | arxiv | pmid | pmcid | nist | w3c | case plus fallback null for plain text). Unrecognised identifiers degrade to a regular search so the command never fails silently.
The kind describes the identifier, not the archive: a well-formed DOI this archive does not hold answers with kind: "doi", total: 0 and an empty results list, which is a correct empty answer rather than a failure. Every example above resolves to at least one document today — the suite that drives the shipped CLI against the live API asserts exactly that, so an example can only rot if that check is skipped.
The conceptio mcp command starts a stdio JSON-RPC MCP server. It is dependency-free (no MCP SDK required) and works with any MCP client.
The server is dual-era: it answers the current 2026-07-28 revision — per-request _meta, server/discover, resultType, cache hints — and still serves the older initialize handshake (2024-11-05 … 2025-11-25) for clients that predate it. A client that speaks both eras probes with server/discover first and finds us; a handshake client is served exactly as before.
A key is required for tool calls. The server starts without one, so a host can discover it and read its tool list — and then answers every tools/call with an in-band error carrying the setup steps. Hand it the key either way: run conceptio auth once, or give it to the host through the host's own environment, which is how the official registry listing declares it:
{ "mcpServers": { "conceptio": { "command": "conceptio", "args": ["mcp"],
"env": { "CONCEPTIO_API_KEY": "ckey_live_…" } } } }
| Tool | Description |
|---|---|
conceptio_search | Search the archive (query, optional limit 1–20, optional category). Returns structured results with titles, authors, years, source, snippet, and direct_pdf_url when available. |
conceptio_search_batch | Run multiple searches in one call — queue 1–50 as a background job and return an opaque handle (sync omitted/false), or set sync: true to run 1–10 immediately and return all results in one response. |
conceptio_resolve | Resolve a known identifier — RFC (RFC 2119), DOI (doi:10.1109/access.2020.2986772), arXiv (2604.08499), PubMed ID (PMID 41961061), PubMed Central ID (PMC10601397), NIST/FIPS designation (NIST FIPS 199), W3C spec shortname (w3c_digital-credentials), or US legal citation / docket (347 U.S. 483, 20-5364) — straight to its document(s). Unrecognised identifiers fall back to a text search. |
conceptio_download_pdf | Download the original open-access PDF for a Conceptio document ID or a direct PDF URL to a local path. |
conceptio_get_citation | Get a citation for a document ID in any of 11 formats (BibTeX, APA, MLA, Chicago, IEEE, Harvard, RIS, Bluebook, OSCOLA, ISO 690, ANSI Z39). |
conceptio_get_document | Full metadata (title, author, source, category, license, year, language, URL, direct PDF URL, description) for a document ID. |
conceptio_graph_walk | Walk the reference graph from a seed source_id — what it cites (direction: 'out'), what cites it ('in'), or 'both' — one or two hops, optionally filtered to the cites / updates relation kinds. Returns nodes with their distance from the seed and canonical edges carrying their kinds. Metadata-only: it spends no credits. |
conceptio_connectors_send | Save one document to Zotero, or open a metadata-only Obsidian handoff. Server-side ownership, connector trial and failure semantics apply. |
conceptio_connectors_send_all | Bulk-save up to 500 document ids to Zotero. Requires Pro, institutional or licensed access — there is no free-trial path. |
Add to claude_desktop_config.json:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json{
"mcpServers": { "conceptio": { "command": "conceptio", "args": ["mcp"] } } }
Settings → Cursor Settings → MCP → Add new MCP server:
{
"mcpServers": { "conceptio": { "command": "conceptio", "args": ["mcp"] } } }
The same JSON shape works in any MCP-aware client — point it at conceptio mcp and the nine tools above are exposed automatically. An MCP host may supply the credential by environment (CONCEPTIO_API_KEY, or CONCEPTIO_BEARER_TOKEN for a signed-in session) instead of writing ~/.conceptio/config.json.
After adding, restart the client and you can ask, for example:
*"Find the NIST post-quantum encryption standard and download the PDF into my workspace."*
echo '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | conceptio mcp
Windows PowerShell quirk: pwsh pipes text to native commands as UTF-16,
which the server (UTF-8 JSON-RPC) answers with a
Parse error. Real MCP
hosts speak UTF-8 and are unaffected — this only bites hand-rolled
