Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

build-connector scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Build Connector Workflow

You are building an Elliot connector — a JSON definition that wraps a data source in agent-ready MCP tools.

The tool sequence

Build always follows this order — each tool depends on the one before it:

elliot_set_context      → name the connector + product
elliot_discover_source  → register the API / DB, materialize its tables
elliot_query_sql        → inspect the real columns before designing tools
elliot_create_tool      → define one tool (verb-first description + SQL)
elliot_preview_tool     → run that tool against sandbox data, verify rows
elliot_build_connector  → assemble all registered tools into a connector
elliot_lint_connector   → check the built connector; fix, rebuild, re-lint
elliot_export_connector → write the connector file to disk

elliot_lint_connector, elliot_run_eval, and elliot_export_connector all operate on the connector produced by elliot_build_connector — if you skip the build step they have nothing to work on.

Workspace state

Existing connectors: !ls connectors/*.connector.json 2>/dev/null | xargs -I{} basename {} .connector.json | tr '\n' ', ' || echo "(none yet)" Elliot plugin: !curl -s http://localhost:3000/health 2>/dev/null | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('status','unknown'))" 2>/dev/null || echo "not running — start Elliot first: honcho start"

Steps

1. Name the connector

Call elliot_set_context with:

  • name: slug-style name (e.g. "acme-crm")
  • description: one sentence describing the product

2. Describe the source

Call elliot_discover_source. Collect from the user:

  • Base URL (for REST) or connection string format (for DB — never log the value)
  • Auth type: bearer, api_key, basic, or none
  • Env var name holding the credential (e.g. ACME_API_KEY)
  • Pagination style if REST: cursor, offset, page, link_header, or none

3. Explore the data shape

First, see what's loaded — call elliot_list_sources for a roster of every discovered source (table name, row count, columns).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

build-connector is a skill published in the GitHub repository EliBarak12/Elliot (11 stars, last pushed 9d ago), licensed MIT. It adds 47 tokens to every session and 3,182 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
