marklogic-mcp: Instructions file for Claude Code

CLAUDE.md

marklogic-mcp CLAUDE.md is an instructions file for Claude Code from tternquist/marklogic-mcp. It costs 4,056 tokens per session, scanned A, original, MIT.

A set of instructions for building MarkLogic MCP tools around user problems and MarkLogic's built-in data capabilities. MarkLogic is a database that supports documents, search, graphs, and structured queries.

In plain words
What is it for?
Use it when designing tools for bulk imports, value counts, joins, full-text search, graph traversal, or content classification in MarkLogic.
Why use it?
It helps developers choose the right MarkLogic API before exposing a new tool, avoiding technical solutions that do not fit the actual data task.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is tternquist/marklogic-mcp's own configuration. It tells Claude Code how to work on marklogic-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything marklogic-mcp configures →

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.

Security

Grade A, and why

marklogic-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 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.

MarkLogic MCP — Agent Working Instructions

This file is read automatically by Claude Code when working in this repository. Follow all principles below for every feature addition, bug fix, and refactor.


Core Principle: Problem-First Thinking

Before writing any new tool, prompt, resource, or client method, answer:

  1. What is the user problem? State it as a concrete goal, not a technical task.

    • Bad: "expose the /v1/values REST endpoint"
    • Good: "allow agents to count distinct values of a field without scanning every document"
  2. What is the MarkLogic-native capability? Every user problem has a best-fit MarkLogic API. Identify it before writing any code.

    • Bulk import → Flux pipeline (flux_import)
    • Counting/bucketing → Values/range index API (ml_values_query)
    • Joins/aggregates → Optic API over TDE views (ml_optic_query)
    • Full-text → Universal index search (ml_search)
    • Graph traversal → Triple store / SPARQL (ml_sparql_query)
    • Content classification / auto-tagging → Semaphore CLS + KMM (semaphore_classify, semaphore_publish, flux_import with classify_with_semaphore: true)
  3. What must an agent discover first? If the tool requires a pre-existing index, collection, or TDE template, document that prerequisite in the tool's description string so the agent knows to check before calling.

  4. Is this already covered? Check the 18 existing tool groups before adding a new tool. Extend an existing tool (via a new parameter) rather than adding a new one unless the problem type is genuinely distinct.


Where Guidance Lives — Skills First

Tool descriptions are interface contracts. Skills are the manual. Do not put tutorials, recipe collections, or troubleshooting playbooks into a server.tool() description string — that text is loaded into every request whether or not it is relevant.

Agent Skills (.claude/skills/<name>/SKILL.md)

Skills follow the Agent Skills spec and are discovered automatically by Claude Code, GitHub Copilot CLI, and other spec-adopting agents from .claude/skills/. A skill is YAML frontmatter plus Markdown:

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.
