  • census_get_source

    Get a single source connection by id. Census: GET /sources/{id}.

  • census_list_destinations

    List configured destination connections (SaaS apps data is synced INTO, e.g. Salesforce, HubSpot, Marketo). Census: GET /destinations.

  • census_get_destination

    Get a single destination connection by id. Census: GET /destinations/{id}.

  • census_list_models

    List SQL models / datasets defined in the workspace (the queries that produce rows to sync). Census: GET /models.

  • census_get_model

    Get a single model by id, including its SQL/query. Census: GET /models/{id}.

  • census_list_syncs

    List syncs (a sync maps a source model to a destination object and keeps them in sync). Returns id, label, status, source_attributes, destination_attributes. Census: GET /syncs.

  • census_get_sync

    Get a single sync's full configuration by id. Census: GET /syncs/{id}.

  • census_list_sync_runs

    List sync run history (each run's status, records processed, timing). Filter by sync_id. Census: GET /sync_runs.

  • census_get_sync_run

    Get a single sync run by id — status, counts, errors. Census: GET /sync_runs/{id}.

  • census_list_segments

    List audience segments defined in the workspace. Census: GET /segments.

  • census_list_workspaces

    List workspaces in the organization (note: usually requires an organization-level token). Census: GET /workspaces.

  • census_trigger_sync

    TRIGGERS a sync run for the given sync id — this KICKS OFF a live data sync that writes records into the connected destination SaaS tool. Set force_full_sync=true to re-sync all rows instead of just changes. Census: POST /syncs/{id}/trigger.

Common questions

Is Census MCP by usefulapi safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.37.3) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Census MCP by usefulapi

Manage Census reverse-ETL from Claude, Cursor, or any MCP client — read sources, destinations, models, syncs and run history, and trigger syncs that push warehouse data into your SaaS tools. Hosted, no local install: connect with your Census API key.

Live endpoint: https://census.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://census.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http census https://census.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "census": { "url": "https://census.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Census credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/census/

On first connect you'll paste your Census API key (Census → Workspace settings → API Access). It's validated, stored per-user, and scoped to you — no keys in config files.
