Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00054 | $0.02539 |
| Opus 5 | $0.00027 | $0.01269 |
| Sonnet 5 | $0.00011 | $0.00508 |
| Haiku 4.5 | $0.00005 | $0.00254 |
Grade A, and why
mcp-server 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 — 297 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mcp Server
Use When
- Building MCP servers in Java/Spring Boot for AI agent tool access
- User mentions MCP, Model Context Protocol, or Java agent tool registration
Workflow
- Confirm the change matches this skill's domain triggers before coding.
- Follow the domain guide conventions and gotchas below — not generic Spring Boot defaults.
- Apply project-specific response envelopes, DTO boundaries, and dependency injection rules.
- Validate with targeted tests (slice, integration, or contract as appropriate).
- Capture evidence before merge: tests, migration notes, or observability proof.
Required Checks
- Constructor injection used; no @Autowired field injection on new code
- Controllers return DTOs/envelopes — never raw JPA entities
- Business logic stays in @Service layer, not controllers or repositories
- Error handling uses project-standard envelope or RFC 9457 ProblemDetail
Domain Guide
Official Java SDK: https://github.com/modelcontextprotocol/java-sdk
Maintained by Anthropic in collaboration with Spring AI.
Dependency
The standalone SDK reached 1.0.0 GA (io.modelcontextprotocol.sdk:mcp). Most Spring Boot
apps should use the Spring AI MCP starter instead — it auto-configures the server, transport,
and tool scanning. The starter coordinates were renamed at Spring AI 1.0 GA to spring-ai-starter-mcp-server-*.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mcp-server is a skill published in the GitHub repository vaquarkhan/Fullstack-development-agent-skills (2 stars, last pushed 20d ago), licensed MIT. It adds 54 tokens to every session and 2,539 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
