Dictlookup

dictlookup

Words rarely sit in one language only. dictlookup is a small local bridge to the hosted kasahorow MCP service: you give it a word or short phrase together with your language and the word's language, and it returns the dictionary entry — definitions annotated with parts of speech — from the kasahorow dictionary (WOAKA).

Nothing is stored or computed on your own machine. This package answers tools/list locally from the captured tool definition and forwards every tools/call to the hosted service over a streamable-HTTP JSON-RPC session, returning whatever the service sends back unchanged.

This is a labelled subset rebuild: the upstream capture enumerates two tools, and only lookup_word is built here. The other captured tool, validate_translation, is omitted — it is a paid reading whose reply returns a payment link — and it is not registered, not served in tools/list, and not available on the CLI.

The tools

• `lookup_word` — Looks up a word or short phrase in the kasahorow dictionary. word is the word or phrase, fl is your language (an ISO code such as en), and tl is the language of the word (an ISO code such as ak or sw). All three are required. Returns definitions with parts of speech.

Install and run

As an MCP server via npm:

npx -y @reneturcios/dictlookup mcp

MCP client configuration:

{

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

As a container:

docker run -i ghcr.io/cloudcorprecords/dictlookup

docker run --rm ghcr.io/cloudcorprecords/dictlookup lookup_word '{"word":"akwaaba","fl":"en","tl":"ak"}'

CLI

One binary serves both the command line and the MCP server. Each tool is a subcommand taking a single JSON string with that tool's arguments:

dictlookup lookup_word '{"word":"akwaaba","fl":"en","tl":"ak"}'

dictlookup --version

Exit codes: 0 when the forwarded call succeeds, 1 when the upstream result is an error, and 2 for usage problems such as an unknown subcommand or a malformed JSON argument.

Configuration

• KASAHOROW_MCP_URL — Overrides the upstream endpoint. The default is the pinned hosted endpoint, https://nabanya.kasahorow.com/mcp. (The override variable is a reconstruction added by this rebuild.)
• KASAHOROW_ACCESS_KEY — When set, its value is sent to the upstream on every request as an X-Kasahorow-Access: header. When it is not set, no such header is sent.
• KASAHOROW_EMAIL — When set, its value is sent to the upstream on every request as an X-Kasahorow-Email: header. When it is not set, no such header is sent. (The header names are pinned by the registry record; the env forwarding is a reconstruction added by this rebuild, and the tool surface was captured keyless.)

Upstream failures — a JSON-RPC error from the service, a non-2xx response, an unreadable body, or a request that fails outright — are reported to the caller as an error result whose text starts with dictlookup error:.

How forwarding works

The first forwarded call opens a session: an initialize request (protocol version 2025-03-26), followed by a notifications/initialized notification, then the tools/call itself. If the service answers the initialize request with an Mcp-Session-Id header, that value is carried on every later request, and the open session is reused for the rest of the process. Replies are accepted either as plain JSON or as server-sent events. Successful results pass through verbatim, including any isError flag and any extra fields the service includes.

Development

npm install

npm run build # tsc -> dist/ (dist/cli.js is the bin) npm test # tsx --test test/*.test.ts — stubbed upstream, no network npm run dev # run the CLI from source

The test suite checks the served tool list against the captured surface, asserts the omitted validate_translation tool is absent at the registry, MCP and CLI levels, exercises the session handshake and its reuse, covers both forwarding-header branches for the access key and the email, and verifies that arguments go upstream untouched and results come back untouched.
