What is teradata-mcp-server CLAUDE.md?

A development guide for a server that lets AI assistants work with Teradata databases through the Model Context Protocol, a standard way for models to call external tools. It lists installation, profiles, connection settings, optional modules, checks, tests, and Docker usage.

Use it when installing, configuring, testing, linting, type-checking, containerizing, or extending the Teradata database server.

It explains how to start the server and connect it to Teradata, while showing which commands are needed to check code and run integration tests.

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	$0.01780	$0.01780
Opus 5.5	$0.00712	$0.00712
Sonnet 5.5	$0.00356	$0.00356

Security

Grade A, and why

teradata-mcp-server 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 1mo 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

Request Flow

server.py — CLI argument parsing, calls create_mcp_app()
app.py — FastMCP app factory. Creates the MCP instance, registers tools/prompts/resources based on profile, configures middleware. A teradata_lifespan async context manager (passed to FastMCP(lifespan=...)) owns the TDConn pool lifecycle: creates the pool at server startup and calls engine.dispose() in its finally block on shutdown.
middleware.py — RequestContextMiddleware extracts per-request headers, auth, and session info. Sets Teradata QueryBand for tracing
Tool handlers — Plain sync functions (handle_*) in tools/ subdirectories. Wrapped to async via asyncio.to_thread

Profile-Based Module Loading

Tools are organized into domain modules under src/teradata_mcp_server/tools/:

base/ — Core queries (readQuery, tableList, columnDescription, etc.)
dba/ — Administration & monitoring
sec/ — Security & permissions
rag/ — Retrieval-augmented generation workflows
fs/ — Feature Store (optional, requires teradataml)
tdvs/ — Vector Store operations
bar/ — Backup & restore (optional)
chat/ — Chat completion
qlty/ — Data quality / EDA
plot/ — Visualization (charts)
sql_opt/ — SQL optimization
tmpl/ — Template tools

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.
