01 / Choose your client

02 / Before you connect

Authentication is not specified. Check the project instructions before connecting.

Install the runtime required by the project and make it available to your client.

Project instructionsEnvironment variable names (optional)

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: generated from public install instructions

claude mcp add --transport stdio 'observer' -- 'npx' '-y' '@superbased/observer'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.

21 of 21 tools

Documented tools (21)

From project documentation. A server handshake does not verify each tool’s description or behavior.

cache_status

Live prompt-cache health: which caches are warm, expiring, or cold, with value-at-risk.

check_command_freshness

Did this exact command already run? With what result?

check_file_freshness

Has this file changed since I last read it?

continue_session

A distilled, scrubbed handover of a session from another AI tool, so you can continue its work here.

get_action_details

The raw row, scrubbed of secrets.

get_cost_summary

Per-window spend rollup.

get_failure_context

Error correlation + retry detection.

get_file_history

Derived behaviours: hot files, co-changes, edit→test pairs.

get_redundancy_report

What would Discovery flag for this project?

get_routing_status

Model-routing layer state: phase, available policy templates, tier-table size, decision-log counters.

get_session_message

One full, un-excerpted message from a session's transcript — pulls the complete body a handover excerpt truncated.

get_session_recovery_context

For resuming an interrupted session.

get_session_summary

What did session X actually do? AI-generated 2–4 sentence summaries.
