What is icelandic-morphology-mcp CLAUDE.md?

Project instructions for an MCP server that looks up Icelandic word forms. MCP is a standard way for an AI assistant to call tools provided by another program.

Use them when working on the Icelandic morphology server, including looking up a word, finding its base form, or converting it to a grammatical form such as a case or number.

They explain how the server is organised, how to run its tests, and what each exposed tool does, reducing guesswork when developing or configuring it.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00375	$0.00375
Opus 5.5	$0.00150	$0.00150
Sonnet 5.5	$0.00075	$0.00075
Haiku 4.5	$0.00038	$0.00038

Security

Grade A, and why

icelandic-morphology-mcp CLAUDE.md scanned grade A with 0 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

MCP server that wraps BinPackage (islenska) to provide Icelandic word inflection lookups via the Model Context Protocol.

Key Files

src/icelandic_mcp/server.py - Main MCP server with 3 tools
tests/test_server.py - Test suite (run with pytest)
pyproject.toml - Package configuration

Tools Exposed

Tool	Purpose
`lookup_word`	Look up a word form, return all matching entries
`get_variant`	Convert word to specific grammatical form (case, number, etc.)
`get_lemma`	Find lemma(s) and word class(es) for a word form

Development

# Create venv and install
uv venv
uv pip install -e .

# Run tests
pytest tests/ -v

# Test manually
python -c "from icelandic_mcp.server import lookup_word; print(lookup_word('hestur'))"

Changes

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.
