Available tools 13

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

census
census_get_destination
Get a single destination connection by id. Census: GET /destinations/{id}.
census_get_model
Get a single model by id, including its SQL/query. Census: GET /models/{id}.
census_get_source
Get a single source connection by id. Census: GET /sources/{id}.
census_get_sync
Get a single sync's full configuration by id. Census: GET /syncs/{id}.
census_get_sync_run
Get a single sync run by id — status, counts, errors. Census: GET /sync_runs/{id}.
census_list_destinations
List configured destination connections (SaaS apps data is synced INTO, e.g. Salesforce, HubSpot, Marketo). Census: GET /destinations.
census_list_models
List SQL models / datasets defined in the workspace (the queries that produce rows to sync). Census: GET /models.
census_list_segments
List audience segments defined in the workspace. Census: GET /segments.
census_list_sources
List configured data warehouse sources (Snowflake, BigQuery, Redshift, Databricks, etc.). Census: GET /sources.
census_list_sync_runs
List sync run history (each run's status, records processed, timing). Filter by sync_id. Census: GET /sync_runs.
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_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.

Census — questions

Answers built from our own checks of this server.

What can Census do?
It exposes 13 tools, read directly from the server on our last check. Among them: census_get_destination, census_get_model, census_get_source, census_get_sync, census_get_sync_run, census_list_destinations and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Census working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 33 of 91 checks got a reply (36.3%), average response time 173 ms. The bar chart above shows every period we have measured.
The registry lists Census as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Census?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Census need an API key?
No. Census completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Census?
It answers our handshake in 173 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Census open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
