What is 1c-litecode-mcp CLAUDE.md?

Project instructions for a tool that lets an agent search 1C business-application metadata and BSL code through an MCP server. MCP is a standard way for an AI agent to call external tools.

Understanding the project architecture, locating parsers and search tools, and developing or checking the Memgraph-backed service.

They give the agent a map of the parser, database, and search components so it can work in the repository with the right structure in mind.

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	$0.00403	$0.00403
Opus 5.5	$0.00161	$0.00161
Sonnet 5.5	$0.00081	$0.00081
Haiku 4.5	$0.00040	$0.00040

Security

Grade A, and why

1c-litecode-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.

Architecture

Memgraph (C++) -- graph DB, shared by all MCP services
MCP services -- Python 3.12 + FastMCP, SSE transport
All projects share one Memgraph, isolated by project_name
No LLM, no embeddings -- pure template Cypher queries

Key technical notes

Memgraph uses Neo4j Bolt driver (neo4j Python package) with auth=None
Memgraph toLower() doesn't work with Cyrillic -- search uses Python-side variants
CONTAINS predicate instead of fulltext index (Memgraph has no native fulltext)
Data loads in background thread so MCP server starts immediately

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.
