    How to connect

    How to connect 2b2t Atlas to Claude

    The server address to paste into Claude settings:

    https://api.blackportal.cloud/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect 2b2t Atlas to ChatGPT

    The server address to paste into ChatGPT settings:

    https://api.blackportal.cloud/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    How to connect 2b2t Atlas to Cursor

    The server address to paste into Cursor settings:

    https://api.blackportal.cloud/mcp

    Fastest: click Open in Cursor below and confirm the prompt.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    If the service needs sign-in, an authorize button appears next to the server in the MCP list.

    Server tool list (21)

    Raw names from tools/list. Only developers need these.

    get_locationGet one canonical Atlas location with coordinates, history, groups, Archive warps, renders, attachments, WDL links, and provenance URLs.
    get_warpsList every Archive warp linked to a location, including landing coordinates, capture date, checksum, and WDL links when available.
    get_render_metadataList public map-render metadata for a location, including tile templates, exact bounds, coordinate scheme, dates, provenance, and source-WDL links.
    get_highwayGet one public, approved highway or canal with native-dimension geometry, construction metadata, credited groups, evidence notes, and map/API links.
    get_world_downloadsList publicly downloadable world snapshots for a location. Returns metadata and HTTPS ZIP URLs, never binary file bytes. WDLs are bounded historical captures, not complete copies of 2b2t.
    research_areaResearch nearby locations, credited groups, preservation availability and nearest native-dimension highways in one call. No spatial NoCom inference. Example: {"location_name":"Block Game Jerusalem","radius":25000,"preserved_only":true}.
    find_recently_added_or_modifiedFind location records added/modified in Atlas during inclusive UTC dates, newest matching timestamp first. Not historical capture dates or a complete change log; render-only changes may not update a location. Example: {"from":"2026-09-01","to":"2026-09-14","kind":"added"}.
    find_locations_by_time_rangeFind locations with a dated Archive warp or public render captured within an inclusive time range.
    get_nocom_datasetGet Nocom World Pulse historical dataset provenance, per-dimension counts, coverage, tile links and caveats. Observations are not players, visits or ownership; aggregate coverage begins March 2020, not 2018.
    get_nocom_periodsGet up to 39 Nocom observation aggregates and tile templates by dimension and overlapping fixed 30-day UTC buckets. Date filters select whole buckets; results are not exact-day counts or player counts.
    search_locationsSearch documented 2b2t locations by name, description, tag, Archive warp, dimension, group, preservation status, or render availability. Returns at most 100 compact records with canonical links.
    find_highways_near_locationFind nearest points on approved highway polylines. Historical geometry, not routing or live passability. Example: {"location_name":"Block Game Jerusalem","highway_dimension":1,"limit":3}.
    search_groupsSearch documented 2b2t groups by name, history, or activity classification.
    search_highwaysSearch public, approved 2b2t highways and canals by name, history, dimension, or attributed group.
    get_nocom_highway_activityGet released historical Nocom highway observation counts by compass direction and fixed 30-day bucket. At most 136 rows per dimension or 17 per direction. Counts reflect scanner bias, not unique players/trips. End has no released highway series.
    find_locations_nearFind locations by exact planar distance. Accepts coordinates or an exact location name/ID; filters before limiting. Example: {"location_name":"Mu Megabase","radius":30000000,"limit":10,"exclude_origin":true}.
    find_preserved_buildsFind preserved 2b2t builds that have both a public map render and a downloadable bounded world snapshot, optionally filtered by group, dimension, or capture dates.
    get_groupGet one group with its history, aliases, links, attributed builds, attributed highways, roles, and canonical URLs.
    get_group_buildsList locations explicitly attributed to a group, including roles, coordinates, render counts, and canonical links.
    get_dataset_statsReturn current counts and machine-readable discovery links for the public 2b2t Atlas dataset.
    research_locationResolve a location name and return the best full Atlas record, alternate search candidates, nearby places, relationships, and an evidence-use reminder. Useful as one-call research context.
