Index Server
Index, search, validate, and promote MCP instructions and rules across repos so agents follow one curated knowledge base.
Overview
Index Server is an MCP server for the Build phase that indexes, searches, validates, and promotes MCP instructions and cross-repo agent knowledge.
What is this MCP server?
- Search and CRUD over MCP instruction documents with validation hooks
- Cross-repo knowledge promotion so shared rules graduate from experiments to canon
- Published as @jagilber-org/index-server npm stdio package version 1.28.9
- Supports maintaining agent instruction libraries at scale across multiple repositories
- Developer Tools focus: structure for SKILLS, rules, and MCP metadata—not runtime hosting
- Package version 1.28.9 (@jagilber-org/index-server)
- Transport: stdio; registryType npm
- Capability areas stated: search, CRUD, validation, cross-repo promotion
What problem does it solve?
Scattered SKILL files and repo-specific rules make it impossible for agents to find authoritative instructions quickly.
Who is it for?
Solo builders or small teams curating large MCP instruction sets across multiple GitHub repositories.
Skip if: Projects that only need a single static RULES.md with no search, validation, or promotion workflow.
What do I get? / Deliverables
Your agent queries and maintains a validated instruction index via MCP, with a path to promote shared knowledge across repos.
- Searchable MCP instruction index with CRUD operations
- Validation step before entries become canonical
- Cross-repo knowledge promotion workflow driven by agent tools
Recommended MCP Servers
Journey fit
Instruction indexing is Build work: you formalize how agents consume rules while the codebase and MCP stack take shape. Agent-tooling fits a dedicated MCP server that CRUDs and searches instruction corpora instead of editing random markdown by hand.
How it compares
Instruction index and CRUD MCP server—not a generic vector database or application error monitor.
Common Questions / FAQ
Who is Index Server for?
Developers who run MCP-heavy workflows and need searchable, validated instruction catalogs instead of duplicated markdown.
When should I use Index Server?
Use it during Build/agent-tooling when you are standardizing rules across repos and want agents to search and update the index via MCP.
How do I add Index Server to my agent?
Install @jagilber-org/index-server, register the stdio MCP entry in your client config, and point your workflow at the indexed instruction store your team maintains.
