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 5.1 | $0.01517 | $0.01517 |
| Opus 5 | $0.00758 | $0.00758 |
| Sonnet 5 | $0.00303 | $0.00303 |
| Haiku 4.5 | $0.00152 | $0.00152 |
Grade A, and why
mcp-sessionize 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 5d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Qué es
Servidor MCP (Model Context Protocol) que expone datos de eventos de Sessionize (speakers, sesiones, agenda) como herramientas y prompts para asistentes IA. Construido con Quarkus 3.33.2 + Java 25 + Quarkus MCP Server 1.13.0 (combo certificada por la doc oficial del MCP server). Se distribuye como ejecutable nativo (Mandrel) y vía npx mcp-sessionize.
Comandos
./mvnw quarkus:dev # Dev mode (HTTP habilitado, log DEBUG, live reload)
./mvnw verify # Build + tests (lo que corre CI)
./mvnw test # Solo unit tests
./mvnw package -Dnative # Ejecutable nativo (requiere Mandrel/GraalVM)
docker build -t mcp-sessionize . # Imagen nativa multi-stage
# Un solo test / método
./mvnw test -Dtest=SessionizeToolTest
./mvnw test -Dtest=SessionizeToolTest#findSpeaker_returnsMatch
Usar siempre el wrapper ./mvnw. CI (.github/workflows/ci.yml) ejecuta ./mvnw verify con Java 25 (temurin) y, en push a main, publica la imagen a ghcr.io.
⚠️
JAVA_HOMElocal:mvnwpriorizaJAVA_HOMEsobre eljavadel PATH. El proyecto requiere Java 25 (maven.compiler.release=25, module imports + el flag--sun-misc-unsafe-memory-accessde.mvn/jvm.config, que solo existe desde Java 23). SiJAVA_HOMEapunta a Java ≤21 el build falla conUnrecognized option. Forzar el JDK correcto, p.ej.:JAVA_HOME="$HOME/.sdkman/candidates/java/current" ./mvnw verify # con sdkman 25-graalce
Arquitectura
Tres capas, todas en el paquete canónico io.mcp.sessionize:
client/SessionizeClient— interfaz REST Client de MicroProfile (@RegisterRestClient(configKey = "sessionize")) contrahttps://sessionize.com/api/v2/{eventId}/view/{Speakers|Sessions|GridSmart}. Fuerza headers no-cache.model/SessionizeModel— clase sellada conrecords inmutables anidados (Speaker,Session,SessionGroup,GridDay, etc.) que mapean el JSON de la API.tool/SessionizeTool— herramientas MCP (@Tool). Los métodos Java songetSpeakers,findSpeaker,getSessionsBySpeaker,getSessions,findSession,getSchedule, pero el nombre MCP registrado lleva prefijo de servicio vía@Tool(name = "sessionize_…")(evita colisiones con otros servers). Todas llevan@Tool.Annotations(readOnlyHint=true, idempotentHint=true, openWorldHint=true)— son de solo-lectura contra una API externa; mantener prefijo + hints al añadir tools. Las tools de listado (get_speakers,find_speaker,get_sessions,find_session) aceptanlimit/offsety devuelven metadata de paginación vía el helperpaginate.prompt/SessionizePrompt— plantillas MCP (@Prompt):event_overview,find_speaker_info,sessions_by_topic,conference_schedule,speaker_sessions,recommend_sessions.
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-sessionize CLAUDE.md is an instructions file published in the GitHub repository labjp-mcp/mcp-sessionize (3 stars, last pushed 6d ago), licensed Apache-2.0. It adds 1,517 tokens to every session, about $0.0076 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.
