Generate at importer.synder.com → Account → API Keys./plugin marketplace add SynderAccounting/gl-importer-plugin
/plugin install gl-importer
Then set your token in the shell that launches Claude Code:
export IMPORTER_API_TOKEN="your_token_here"
Download the latest .mcpb bundle from Releases and double-click it. Claude Desktop will prompt you for the API token.
git clone https://github.com/SynderAccounting/gl-importer-plugin
cd gl-importer-plugin
npm install
npm run build

| Env var | Required | Default | Purpose |

IMPORTER_BASE_URL | no | https://importer.synder.com/api/v1 | Override for staging/test |
Once installed, talk to Claude Code naturally:
~/Downloads/march-bills.csv as Bills into my QuickBooks company."The skill will walk Claude Code through a safe two-step flow: a dry-run that shows the proposed field mapping, then a confirmed call that actually creates the import and polls until it terminates.
The MCP server exposes 19 tools. The ones an LLM will hit most often:
| Tool | Purpose |
|---|---|
import_csv | Happy path. Auto-resolves company, uploads file, runs dry-run, then (on confirm) executes + waits. |
import_wait | Polls a running import to a terminal state with exponential backoff (2s → 1.5× → 30s cap). |
companies_list / entities_list / fields_get | Discover what you can import where. |
mappings_list / mapping_create / mapping_update / mapping_delete | Saved-mapping CRUD. |
import_auto / import_execute | Lower-level: create an import with auto-mapping or an explicit mapping. |
import_status / import_results / import_cancel / import_revert | Lifecycle. |
settings_get / settings_update | Per-company import settings. |
account_get | Whoami / token check. |
Full schemas are emitted at MCP startup — the agent skill (skills/gl-importer/SKILL.md)
also documents the conventions.
