For AI agents
Connect your AI
Every listing on SPACEXPLORATION is searchable from Claude, ChatGPT, Cursor, or any client that speaks the Model Context Protocol. Searching needs no account and no API key — paste one URL and ask.
The server
https://spacexploration.com/mcp Streamable-HTTP MCP endpoint. Read tools work anonymously; account features use OAuth that your client handles for you.
Set it up
Claude (claude.ai & Desktop)
Find SPACEXPLORATION in the Claude directory and connect it. If your organization restricts the directory, use Settings → Connectors → Add custom connector and paste the server URL instead.
https://spacexploration.com/mcp ChatGPT
Find SPACEXPLORATION in ChatGPT's plugin directory and add it. If your workspace restricts plugins, use Settings → Connectors → Advanced → Developer mode and add the server URL as a custom connector instead.
https://spacexploration.com/mcp Claude Code
One command in your terminal:
claude mcp add --transport http spacexploration https://spacexploration.com/mcp Cursor
Add the server to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):
{
"mcpServers": {
"spacexploration": {
"url": "https://spacexploration.com/mcp"
}
}
} Every tool, live
This catalog is generated from the running server — 23 tools, each with the exact argument schema your agent receives. Sign-in is standard OAuth where marked; your client walks you through it. Listing changes always require a verified email and your ownership of the listing.

› get_registry read-only
Returns the full attribute registry — every searchable and filterable field, its type, allowed values, and display label. Read this first to understand the schema before calling search_listings with attribute filters.
{
"type": "object",
"properties": {}
} › search_listings read-only
Search commercial real estate listings. Returns paginated hits with facet counts; every hit carries the public `url` to cite and its `listed_at` / `updated_at` stamps. For AI-driven search, call interpret_search first to convert a natural-language query into structured filters, then pass those filters — and its bounds, when present — here.

} › get_listing read-only
Retrieve the full details of a single listing by its hashid. Returns the complete ListingResource projection including parcel data, all attribute details, and attachments: photos, plus the public documents the broker attached (brochures, offering memoranda, site plans) with their filename and a direct download URL. Broker contact is included only when the requesting user is authorised to manage the listing; such a user also gets every lease suite with its id and status, the rows update_listing takes back.

} › interpret_search read-only
Translate a natural-language property-search sentence into a structured filter payload compatible with search_listings. Use this as a transparent intermediate step: pass the user's raw query here, then forward the returned filters — and the returned bounds, when present (they carry the "near <place>" intent) — to search_listings.
{

} › get_parcel read-only
Read a building SPACEXPLORATION already has, by the hashid that look_up_parcel returns or that a building page URL (/parcel/{hashid}/...) contains. Returns the same data as look_up_parcel: the address and building page URL, the FEMA flood zone and natural hazard risk, EPA records nearby, Census demographics, access and nearby amenities, the county public record with numbered sources where research has found it, and any live listings in it. It looks nothing up and starts nothing, so use it to check on a building whose status.gathering or status.researching_county_record was true.

} › get_faq read-only
Answers to the questions people ask about SPACEXPLORATION itself: what it costs, listing a property, where leads go, finding property, AI assistants (including the built-in one), where the building data comes from, and accounts. Call this before answering any question about how SPACEXPLORATION works or what it costs, answer from what it returns, and link the entry's `url` (or its `see` page when it has no url). Pass `topic` to read one group; leave it out for all of them.

› look_up_parcel
Look up any US building by its street address and get the public data SPACEXPLORATION keeps on it, whether or not it is for sale or lease: the FEMA flood zone and natural hazard risk, EPA records nearby (including leaking underground storage tanks), Census demographics around it, access and nearby amenities, and, for a building that has been listed on SPACEXPLORATION, the county public record (owner, assessed and market values, taxes, tax lots, recorded sales) with a numbered source for each figure. Also returns the building page URL to share and any live listings in it (pass a listing hashid to get_listing). The first lookup of a building gathers its data in the background, which takes a minute or two: while status.gathering or status.researching_county_record is true, check on it with get_parcel and the returned hashid instead of repeating the lookup. Requires a signed-in account.
{
"properties": {
"address": {
"description": "A full US street address with its street number, e.g. \"910 Elysian Fields Ave, New Orleans, LA 70117\". A road, a town or a partial address is refused: the lookup has to name one building.",

} › geocode_address read-only
Geocode a free-form US address into coordinates and structured components (street_address, city, county, state, postal_code) plus a formatted address and place_id — exactly the identity fields create_listing requires. Use this first, then pass the result straight into create_listing instead of supplying your own coordinates.

} › create_listing
Create a new draft listing. Returns the full created listing exactly as stored, including its hashid and status. Pass an idempotency_key (any client-generated string, e.g. a UUID) to make the call safe to retry — re-sending the same key returns the original listing instead of creating a duplicate.

} › attach_listing_photo
Attach a photo to a listing you own directly from its public URL — one call, no separate sign/upload/confirm. The server fetches the image and ingests it with auto-generated thumbnail/hero/full variants. Only https image URLs whose host is publicly routable are accepted. The photo is content-moderated (must be real-estate related and safe) before it can appear publicly — the returned snapshot includes the moderation_status (approved / rejected / escalated) and moderation_reason. A rejected or escalated photo will not be publicly visible and will block publishing until removed or replaced.

} › sign_attachment_upload
Begin an out-of-band file upload. Returns a presigned R2 PUT URL and the headers to use; the file bytes are uploaded directly to storage, never through this channel. After PUTting the file, call confirm_attachment_upload with the returned attachment_id. Supports listings (photos, documents), users (avatar), and pages (cover, photos). Avatars pass an automated content check before they appear publicly.

Finalize an out-of-band upload after the file bytes have been PUT to the presigned URL. Verifies the stored object matches what was signed (size and content-type) and marks the attachment ready.

]
} › delete_attachment destructive
Delete an attachment you own by its ULID. Soft-deletes the row so it no longer appears on the listing. Use this to clean up an abandoned upload (one you signed but never finished) or a photo you no longer want. Idempotent: deleting an already-deleted attachment succeeds.
{

Kick off the publish pipeline for a draft listing. Enriches with AI, gathers market data, then transitions the listing to Active. Returns the pipeline ID to track progress.

Get the status of your listing publishes. Pass a listing hashid for the detailed status of that listing's latest publish run — overall state (pending/running/completed/failed), current phase, per-step progress, and any failure reason. Omit the hashid to list your recent publish runs across all your listings. Use this to track a publish_listing call to completion.

The common journeys, end to end — from a pasted URL to a published listing.
› Connect Claude to SPACEXPLORATION
Wire Claude (or any MCP client) to the live listings server. Searching works the moment you connect — no account, no API key.
Claude on the web or Desktop
SPACEXPLORATION is listed in the Claude directory. Open its directory page and connect it — the tools appear in Claude's tool picker immediately.
If your organization restricts directory connectors, add it by URL instead:
- Open Settings → Connectors → Add custom connector.
- Paste the server URL shown under "The server" on this page (it ends in
/mcp). - Save.
Claude Code
One command in your terminal:
claude mcp add --transport http spacexploration https://spacexploration.com/mcp
Verify it works
Ask your client:
Find industrial listings over 50,000 sq ft in Texas.
A connected agent will call get_registry to learn the filter vocabulary, then search_listings — anonymously. If the tools never appear, re-check the URL: the endpoint speaks streamable-HTTP MCP, not SSE.
When sign-in happens
Saved searches, geocoding, and listing authoring need an account. You don't provision anything: the server advertises its OAuth metadata, your client registers itself (Dynamic Client Registration) and walks you through a standard browser sign-in the first time an account-bound tool runs. Headless agents that can't open a browser can follow the claim ceremony in auth.md instead.
› Build a saved-search agent from scratch
Turn a plain-English brief into a persistent, alerting search in three tool calls.
1. Interpret the brief
Hand the user's words to interpret_search:
{ "prompt": "owner-user buildings near Denver under $4M with a dock door" }
It returns a structured filters map (keyed by registry field names), plus bounds when the query names a place. Forward both to the next call — dropping bounds loses the "near Denver" intent.
2. Run it
Call search_listings with the interpreted filters and bounds and show the user what came back. Adjust filters by hand if the user refines — get_registry lists every legal field, its type, and its allowed values.
3. Persist it
Once the user is happy, call save_search (this is the first account-bound call, so OAuth kicks in here):
{
"name": "Denver owner-user under $4M",
"query": "dock door",
"filters": { "listing_type": ["sale"], "price": { "max": 4000000 } }
}
A saved search keeps query and filters but not bounds, so carry a "near Denver" intent over as city or county filters.
The platform emails the user a digest when new matching listings publish — no polling loop to build.
Manage the portfolio of searches
list_my_saved_searches returns everything saved; delete_saved_search retires one by id. A good agent reconciles: before saving, list what exists and update rather than duplicate.
› Pull all my listings into a spreadsheet
Export your whole inventory — drafts and published — into CSV with two tools.
1. Enumerate
list_my_listings (account-bound — your client handles the OAuth sign-in) returns every listing you broker or own, each with its hashid, title, status, and price. The hashid is the only key you need; numeric ids never appear on the agent surface.
2. Hydrate
For each hashid, get_listing returns the full projection: address, pricing, status, and every populated registry attribute with its label and unit.
{ "hashid": "a1b2c3d4" }
3. Shape the rows
Ask your agent to flatten what it fetched:
Make a CSV with one row per listing: title, status, city, state, price, building sq ft, lot acres, year built. Use empty cells where a listing has no value.
Attribute coverage varies by asset type — a land listing has no building square footage. Emitting blanks (not zeros) keeps the spreadsheet honest.
Keeping it fresh
Re-running the two calls is idempotent and cheap. For a recurring report, schedule the same conversation — the hashids are stable across the listing's life.
› Author a listing from a flyer
Two paths from a PDF flyer or offering memorandum to a published listing. Both require a verified email on your account.
The short path: upload it in the editor
Signed in on the web, choose Import listing from document when creating a new listing and upload the flyer. The extraction service reads it synchronously and prefills a draft — headline, pricing, property facts — which you review and publish from the editor. This is the right path when a human is at the keyboard.
The agent path: full MCP authoring
When an agent holds the flyer (or its text), it can author end-to-end:
geocode_address— turn the flyer's address line into the coordinates and county thatcreate_listingneeds.create_listing— returns the new draft, including itshashid; every later call keys on it.update_listing— pricing, marketing copy, parcel facts. A lease is priced per suite: send them inspaces, each with its size and rate. A building leased as one is a single suite, whichlease_rateandavailable_sqftin the pricing group set directly.set_listing_attributes— the rich registry fields, as a map of field name to value. Only fieldsget_registrymarkswritable: trueare accepted; the rest are computed at publish.attach_listing_photo— one call per image URL; the server fetches and ingests it. (For local files, use thesign_attachment_upload→ upload →confirm_attachment_uploadpair instead.)publish_listing— kicks off the asynchronous publish pipeline. Pollget_publish_statuswith the listing hashid until its state iscompleted.
Honesty guardrails
Extract only what the document states. Leave unknown fields empty rather than guessing — publish-time enrichment fills the computed facts (flood zone, demographics, market data) from authoritative sources, and a wrong guess in a broker-asserted field is worse than a blank.
› Add an attribute and watch every AI surface inherit it
How the registry-as-contract works, from the inside. The attribute registry — one database table — is the single schema every surface derives from. Nothing on this page is hand-maintained.
One row, every surface
When an administrator adds a row to the registry (say industrial.dock_doors, a number range applying to industrial assets), each surface picks it up from the same snapshot, with no deploy:
get_registryand theregistry://attributesresource expose it to agents on the next call, typed, with its range hint.search_listingsacceptsattr_industrial_dock_doorsas a filter key immediately.interpret_searchfolds it into the natural-language vocabulary, so "at least 4 dock doors" starts resolving to a structured filter.- The search UI grows a sidebar facet where the row's sidebar position says.
set_listing_attributesaccepts it from authoring agents once the row is marked agent-writable.- Document extraction adds it to what the flyer reader looks for.
- This page — the attribute table above re-renders from the live registry on every request.
The contract
The field name (attr_industrial_dock_doors) is the one identity shared by every query surface. What an agent needs to construct a query — type, control, allowed values, range bounds, writability — is exactly what the registry projection carries; storage internals deliberately never leave the server.
Why this matters to you
If you build against get_registry instead of a hardcoded field list, your agent inherits every future attribute the day it ships. The recipe is no recipe: read the registry, build the query, stay current forever.
The attribute registry
Every filterable field, straight from the live registry —
the same schema get_registry returns. Filter search_listings by the field name; fields marked writable accept values via set_listing_attributes.

Are AI agents welcome on SPACEXPLORATION?
Yes, every one. SPACEXPLORATION is built for AI agents as well as people. Any agent may read our public pages and connect to search every listing, with no account and no API key. Sign in through yours, and it works for you: it saves your searches and manages the listings you own.
Which AI assistants can I connect to SPACEXPLORATION?
Any assistant that supports connectors. Claude and ChatGPT list SPACEXPLORATION in their directories: add it from Claude’s or ChatGPT’s. Grok Bot, Meta Muse, OpenClaw, and every other assistant add it by its address, https://spacexploration.com/mcp, as Connect your AI shows. Searching needs no account; sign in through the assistant and it can create, update, and publish the listings you own.
Can I use SPACEXPLORATION in Claude?
Yes. SPACEXPLORATION is in Claude’s connector directory. Add it there, then ask Claude for property in plain English, such as warehouses near Denver with dock doors. Searching needs no account. Sign in through Claude, and it can save your searches and create, update, and publish the listings you own.
Can I use SPACEXPLORATION in ChatGPT?
Yes. SPACEXPLORATION is in ChatGPT’s plugin directory. Add it there, then ask ChatGPT for property in plain English, such as office buildings for sale in Colorado. Searching needs no account. Sign in through ChatGPT, and it can save your searches and create, update, and publish the listings you own.
Who makes the SPACEXPLORATION plugins for Claude and ChatGPT?
We do. SPACEXPLORATION builds and runs both, along with the server they connect to, so your assistant searches the same live listings you see on the site.
Does my AI assistant cost anything?
Not from us. Connecting your AI assistant to SPACEXPLORATION and using it here is free. If the assistant itself has a paid plan, that is between you and the company that makes it.
