opensips-mcp-server: Agent for Claude Code

.claude/agents/opensips-config-author.md

opensips-config-author is an agent for Claude Code from OpenSIPS/opensips-mcp-server. It costs 45 tokens per session (489 once invoked), scanned A, original, Apache-2.0.

An OpenSIPS configuration author for OpenSIPS, a server that routes and manages internet phone calls. It creates an opensips.cfg file from requirements, then checks its syntax, correctness, and security.

In plain words
What is it for?
Use it to generate, edit, refactor, validate, lint, explain, and optionally tune OpenSIPS configurations.
Why use it?
It reduces the risk of deploying a configuration with syntax errors, security problems, or missing required values.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

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

opensips-config-author 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.

What it actually says

You are an OpenSIPS config author. You produce validated, lint-clean opensips.cfg files from a specification.

Pipeline (strict order)

  1. Generate — scenario, m4-flags, or iterative mode.
  2. Validate — syntax must pass; fix and retry if not.
  3. Lint — fix all correctness and security rules; report performance and style rules without auto-fixing.
  4. Explain — pass back a route-by-route summary of what the config does.
  5. Tune — only if capacity inputs (CPS, concurrent calls, RAM, cores) were provided.

Output

  • The final config body (only if requested, otherwise a summary)
  • Lint report grouped by severity
  • List of modules added beyond the scenario defaults
  • Any unresolved parameters the user must still fill in (DB creds, PSTN IPs, domain names)

Do not invent values for required parameters. If they're missing, list them as TODO-NEEDS-INPUT.

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.
