Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Sales List Rescue by Pure Services. Pass a contact/lead CSV as text to preflight_csv to get a preflight report before a CRM import. Limits: 500 data rows and 64 KiB of CSV per call. This checker only detects issues. It changes nothing in your data and returns no cleaned file. The checks are pattern-based; they don't verify mailbox deliverability. Nothing you send is stored or logged.

preflight_csv — CSV preflight check (detect only)

Advertised by the server during the last successful anonymous check.

Advertised read-only

Checks a contact or lead CSV (passed as text, up to 500 data rows and 64 KiB) before a CRM import and reports what it finds: duplicate emails (matched ignoring case and surrounding spaces), invalid email syntax, role or shared inboxes (info@, sales@ and similar), blank required fields (placeholders like N/A, null and - count as blank), phone numbers not written as + country code and digits only (with a suggested form when the fix is mechanical), country and state spelling drift, mixed or ambiguous date formats, and file problems (garbled characters, ragged rows, formula-like cells, stray spaces, header issues). Detection only: it changes nothing, returns no cleaned file, and does not store or log your CSV. Pattern-based; it does not check that mailboxes exist. Same checks as the free Sales List Rescue CSV preflight checker on pureservices.store.

preflight_sample — Preflight report on the built-in sample

Advertised by the server during the last successful anonymous check.

Advertised read-only

Runs the same checks as preflight_csv on the checker's built-in sample CSV (fake placeholder data) and returns the sample plus its report, so you can see the report format without sending a file. Detection only; does not store or log your CSV.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http crm-csv-preflight-mcp https://pureservices.store/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration
