How to connect
How to connect crosstabs to Claude
The server address to paste into Claude settings:
https://mcp.crosstabs.com/mcp
- Open Claude (claude.ai or the desktop app).
- Go to Settings → Connectors.
- Click Add custom connector.
- Paste the server address copied below into Remote MCP server URL and click Add.
- 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 crosstabs to ChatGPT
The server address to paste into ChatGPT settings:
https://mcp.crosstabs.com/mcp
- Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
- Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
- Open Settings → Connectors and click Create.
- Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
- Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
- 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 crosstabs to Cursor
The server address to paste into Cursor settings:
https://mcp.crosstabs.com/mcp
Fastest: click Open in Cursor below and confirm the prompt.
Manually:
- In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
- Paste the JSON copied below into
~/.cursor/mcp.json(per project:.cursor/mcp.jsonin the repo root). - 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 (52)
Raw names from tools/list. Only developers need these.
| search | Discover fixed Crosstabs methodology, limitations, and evidence pages. |
| fetch | Fetch one fixed Crosstabs evidence record by identifier. |
| analyze_crosstab | Compute deterministic statistics from a bounded aggregate contingency matrix. |
| render_crosstab | Render a deterministic evidence-linked aggregate crosstab widget. |
| get_started | Get client-specific connection guidance, a health check, and the first prompt to try. No account, workspace, or upload is required. |
| run_demo_analysis | Run an instant, upload-free tour using a fixed synthetic survey table. Returns an AI-ready answer, numbers, interpretation, warnings and next action. |
| get_headless_capabilities | Describe the full accountless hosted MCP, privacy, retention and execution limits. |
| get_runtime_status | Inspect this hosted runtime and its fixed resource limits. |
| create_workspace | Create a private temporary workspace without signing in. Explain that uploads leave the device, then obtain consent. The secret token is the sole access credential and cannot be recovered. |
| get_workspace | List this temporary workspace's files, recent jobs and expiry. Includes a private upload link. |
| delete_workspace | Permanently delete the temporary workspace and all active project, file and job data. This revokes its token. |
| get_job | Read a queued analysis job. Wait at least two seconds between polls. Only succeeded jobs contain completed results; failed jobs contain an error. Use get_download_link for artifact IDs, or get_rendered_table for completed render_project_table jobs. |
| get_download_link | Create a private browser download link for an uploaded file or generated artifact in this workspace. The link contains a secret in its fragment; never share it publicly. |
| get_rendered_table | Render the canonical aggregate result of a succeeded render_project_table job. Respondent rows are never included in the widget. |
| analyze_survey | Run a governed crosstab for an existing hosted project. This task shortcut uses the same deterministic run_table engine and returns a job to poll with get_job. |
| build_tab_book | Build a reusable tab book for an existing hosted project. This task shortcut uses the same deterministic run_tab_book engine and returns a job to poll with get_job. |
| compare_survey_waves | Compare compatible saved survey waves. This task shortcut uses the same deterministic compare_waves engine and preserves all comparability warnings. |
| create_editable_report | Generate an editable PPTX or DOCX report pack from an existing hosted project. Use get_download_link on the returned artifact ID after the job succeeds. |
| create_analysis_plan | Create a portable revision-bound document for explicitly selected saved tables without mutating the project. Queues a hosted job; use get_job to retrieve its result. |

| run_analysis_plan | Validate and execute a portable plan against one loaded project revision, returning aggregate evidence and review findings. Queues a hosted job; use get_job to retrieve its result. |
| preview_raking_weights | Preview explicit population margins against the saved active wave. Returns aggregate balance, trimming and effective-base diagnostics with a revision-bound review fingerprint; respondent weights remain in the temporary hosted workspace. Queues a hosted job; use get_job to retrieve its result. |
| apply_raking_weights | Recompute a reviewed weighting fingerprint and atomically save a new sampling-weight column and definition with human approval, warning acknowledgement, revision checks and replay.
