Officelens

officelens

officelens is a small local bridge to the Family Office Registry's hosted MCP server, a sourced and dated registry of family offices and related firms centred on Switzerland and Liechtenstein, with coverage extending to Austria, Germany, Dubai and registered advisers in the US.

The bridge keeps no registry data and runs no lookups of its own. It serves the upstream server's tool list locally, exactly as captured from the live endpoint, and forwards each tool call upstream, returning the result untouched. The whole captured surface is read-only: this rebuild adds no write capability.

Tools

• search_registry — search verified family offices and related firms. Everything is optional: q (free text over the open fields — name, city, register id, legal form, focus tags; with a key it also reaches the people and the purpose clauses), country (CH, LI, AT, DE, AE or US), canton (a Swiss canton code such as ZH, ZG or GE), type (SFO, MFO or intermediary), alloc (how firms invest — a subscription-only filter the search refuses without a key), page (from 1, default 1), size (1-25 results per page, default 10, capped at 25 without a subscription key) and purpose (one line on what the user is trying to do, logged without the caller and never changing the answer). One page of open records comes back — the same fields the public site publishes. Named people, contact channels, source lists and verification notes need a subscription.
• get_record — one firm by its registry id (the id search_registry returns), plus the same optional purpose line. Without a subscription key this returns the open fields and says how many named roles the full record holds; with one it returns the named roles, the contact channels, the full source list and the verification note.

Configuration

• FAMILYOFFICEREGISTRY_MCP_URL (optional) — override the upstream endpoint. Defaults to https://familyofficeregistry.com/api/mcp. The alias FOR_MCP_URL is also honoured. (The override hook is this rebuild's own labelled reconstruction.)
• FAMILYOFFICEREGISTRY_API_KEY (optional) — when set, every upstream request carries an Authorization: Bearer header; the alias FOR_API_KEY is also honoured. When neither is set, no auth header is sent. (This forwarding is also a labelled reconstruction; the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session with the upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name officelens), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with officelens error: (this rendering is this rebuild's own labelled reconstruction).

CLI

Each tool is also a subcommand taking one JSON argument string (omit it for tools that take none):

npx @reneturcios/officelens search_registry '{"country":"CH","canton":"ZH","type":"MFO"}'

npx @reneturcios/officelens get_record '{"id":"CHE-116.281.419"}' npx @reneturcios/officelens --version

Exit codes: 0 on success, 1 on an isError result, 2 on a usage error.

MCP server

npx -y @reneturcios/officelens mcp

MCP client config:

{

"mcpServers": { "officelens": { "command": "npx", "args": ["-y", "@reneturcios/officelens", "mcp"] } } }

Docker

docker run -i ghcr.io/cloudcorprecords/officelens

docker run --rm ghcr.io/cloudcorprecords/officelens --version

The container's default command is mcp, so the first form is a stdio MCP server; any other arguments reach the CLI normally.

Development

npm install

npm run build npm test npm run dev

The test suite runs entirely against a stubbed JSON-RPC upstream — no live network calls.
