signoz-mcp-server: Instructions file for Claude Code

CLAUDE.md

signoz-mcp-server CLAUDE.md is an instructions file for Claude Code from SigNoz/signoz-mcp-server. It costs 1,499 tokens per session, scanned A, original, Apache-2.0.

A set of development rules for the SigNoz MCP server, including feature planning, documentation, Git and pull-request practices, and coding style. An MCP server is a program that lets an AI tool use defined external capabilities.

In plain words
What is it for?
It helps developers plan non-trivial features, record open questions and decisions, follow repository rules, and prepare changes for review.
Why use it?
It keeps feature decisions traceable by requiring context and plan files, discussion logs, and documented changes.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents.

This is SigNoz/signoz-mcp-server's own configuration. It tells Claude Code how to work on signoz-mcp-server 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 signoz-mcp-server 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

signoz-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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — Development Conventions

Consult docs/ (architecture, MCP best practices) and plans/ (per-feature context and plans) when you need background on a subsystem or an in-flight feature.

Feature Planning Convention

For every non-trivial feature, maintain a file pair in plans/ and commit it alongside the feature PR:

plans/
├── <feature>.context.md   ← prompt, links, open questions, discussion log
└── <feature>.plan.md      ← implementation plan

Rules

  1. Before implementing, check plans/ for an existing context file for the feature.
  2. After each brainstorm exchange, append a dated entry to the discussion log in .context.md.
  3. When the plan changes, rewrite the relevant section in .plan.md and note the change with a dated entry in .context.md.
  4. Mark open questions as resolved (with the answer inline) when they are settled in discussion.
  5. The discussion log in .context.md is append-only: never rewrite or delete prior log entries; it is the audit trail of why decisions were made. Only the Open Questions checklist may be updated in place (rule 4).
  6. .plan.md is rewritten freely: it always reflects current thinking, not history.
  7. Add a ## Status line at the top of every .plan.md:
    • Planning: actively being designed
    • In Progress: implementation underway
    • Done: shipped

File templates for both files live in plans/TEMPLATES.md.

Git & PR

  • Conventional commits: feat:, fix:, chore:, refactor:, test:, docs:.
  • PR titles must follow the same conventional-commit format, e.g. chore(rate-limits): centralize override defaults.
  • Create GitHub issues in SigNoz/nerve-pod by default. Only use another repo when the user explicitly asks for that specific repo.
  • Keep PR body in sync with actual changes.

Code Style

  • Avoid long inline code comments unless needed; keep comments concise and non-redundant.

Client-Visible Writing Style

When editing tool or parameter descriptions, signoz:// resources, prompts, server instructions, or manifest.json descriptions, follow docs/client-visible-writing-style.md. Skip it for code, tests, and internal docs.

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.
