Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02254 | $0.02254 |
| Opus 5 | $0.01127 | $0.01127 |
| Sonnet 5 | $0.00451 | $0.00451 |
| Haiku 4.5 | $0.00225 | $0.00225 |
Grade A, and why
article-mcp CLAUDE.md scanned grade A with 1 finding 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 6d 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.
Reads agent configuration directorieslowAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Configuration paths searched:** `~/.config/claude-desktop/config.json`, `~/.config/claude/config.json`, `~/.claude/config.json` Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Project Overview
Article MCP is a high-performance literature search server based on FastMCP framework that integrates multiple academic databases including Europe PMC, arXiv, PubMed, CrossRef, and OpenAlex. It provides comprehensive literature search, reference management, and quality evaluation tools for academic research.
Architecture
The project follows a standard Python src layout with layered architecture:
- CLI Layer (
cli.py): Main CLI entry point and MCP server creation viacreate_mcp_server() - Tool Layer (
tools/core/): 6 core MCP tool registrations - Service Layer (
services/): API integrations using dependency injection pattern - Middleware Layer (
middleware/): Error handling, logging, and performance monitoring - Resource Layer (
resources/): MCP resources for config and journal data - Compatibility Layer (
main.py): Backward-compatible CLI entry point
The 5 Core Tools
All tools are registered in cli.py:create_mcp_server() with their respective service dependencies:
- search_literature (
tools/core/search_tools.py): Multi-source literature search - get_article_details (
tools/core/article_tools.py): Article details by identifier - get_references (
tools/core/reference_tools.py): Reference list retrieval - get_literature_relations (
tools/core/relation_tools.py): Citation relationship analysis - get_journal_quality (
tools/core/quality_tools.py): Journal quality assessment
Note: The test file test_six_tools.py is a legacy name - it tests these 5 core tools.
Service Injection Pattern
Services are created in create_mcp_server() and passed to tool registrars:
pubmed_service = create_pubmed_service(logger)
europe_pmc_service = create_europe_pmc_service(logger, pubmed_service)
# ... other services
register_search_tools(mcp, {"europe_pmc": europe_pmc_service, ...}, logger)
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.

article-mcp CLAUDE.md is an instructions file published in the GitHub repository gqy20/article-mcp (16 stars, last pushed 8mo ago), licensed MIT. It adds 2,254 tokens to every session, about $0.0113 per session on Opus 5. A static security scan graded it A with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
