Catalog: MCP servers and AI infrastructure in the EIC ecosystem

Last updated on 2026-11-10 | Edit this page

Overview

Questions

  • Which other MCP servers does EIC provide?
  • Where are shared skills kept?
  • How can you use the tools without any setup?

Objectives

  • Find a shared skill in eic/skills before writing your own.
  • Ask the DISpatcher bot a question about data, software, or production.

More EIC servers

The three servers you used are part of a larger set, built mostly in BNL’s NPPS group (this episode is based on Torre Wenaus’s June 2026 talk to the ePIC user-learning WG). The eic GitHub organization has the current list.

Analysis and data

Callout

uproot-mcp: read ROOT/EDM4eic files · available · used in this lesson

uproot logo

eic/uproot-mcp-server reads ROOT files. Used in Episodes 3 and 5.

Callout

xrootd-mcp: find files on the data store · available · used in this lesson

XRootD logo

eic/xrootd-mcp-server browses the ePIC data stores.

Callout

rucio-mcp: query the data-management system · available · used in this lesson

Rucio logo

eic/rucio-eic-mcp-server searches the Rucio data catalog (read-only).

Records

Callout

zenodo-mcp: search the open-data repository · available

Zenodo logo

eic/zenodo-mcp-server searches Zenodo, including ePIC documents.

Code knowledge

Callout

eic-docs-mcp: search the documentation · available

eic/eic-docs-mcp gives full-text search over the eic.github.io pages and the software tutorials, including this one.

Callout

LXR-mcp: source cross-reference · available (BNL-hosted)

Searches the ePIC source code through the LXR browser, which is updated nightly. It runs only on the BNL-hosted services.

Shared skills: eic/skills

The AGENTS.md and SKILL.md you used in Episode 4 live in one analysis directory. eic/skills (site) is the collaboration’s shared repository of such definitions: skills, agents, and four packs that bundle them (onboarding, simulation, reconstruction, analysis), with setup guides for Copilot CLI, Claude, Cursor, Codex, and VS Code. Look there before writing a skill, and contribute the ones that work: a skill that encodes how to find a dataset or check a campaign saves every user the tool calls you counted in Episode 3.

No setup: the DISpatcher bot

DISpatcher is a Mattermost bot (chat.epic-eic.org → dispatcher) that anyone in ePIC can use, in the channel or by DM. It has the data tools from this lesson plus tools for production jobs, physics samples, software, and documents.

Post this in the dispatcher channel or DM the bot:

Which production campaigns contain the BeAGLE eCu ep 10x115 DIS sample, and is it in the newest campaign? For campaign 26.04.1, which generator version and settings produced it, and how many events were produced? Say which tool each part of the answer came from.

Compare its event count with yours from Episode 3

The EIC software portal also has an AI search box (“Ask anything about EIC…”).

corun-ai

BNLNPPS/corun-ai runs longer jobs with larger models and keeps the results. Its first use, codoc-ai, writes software documentation and reviews ePIC pull requests. Ask Torre for an account.

Key Points
  • EIC provides more MCP servers than the three used here.
  • Shared skills and agent definitions are in eic/skills.
  • The DISpatcher bot in Mattermost gives you these tools without any setup.
