File Context Protocol (FCP)

MCP servers that let LLMs interact with complex file formats through verb-based DSLs. Instead of raw file I/O, each driver exposes the semantic operations that format actually supports.

Frameworks

Drivers

Driver Format
fcp-pdf PDF — read, annotate, redact, merge, split
fcp-drawio draw.io diagrams
fcp-midi MIDI composition
fcp-sheets Spreadsheets
fcp-slides Slide decks
fcp-terraform Terraform HCL
fcp-rust Rust codebases (rust-analyzer)
fcp-python Python codebases (pylsp)
fcp-regex Regex via named fragment composition

Five laws

  1. Invisible write — file mutations are tracked with generation counters
  2. Ephemeral agents — fleet processes are reaped on session close
  3. Filesystem coordination — all state flows through the filesystem, never through agent memory
  4. Optimistic concurrency — conflicts resolve at write time via Hot PR
  5. Invisible infrastructure — always

Provenance

This org is attested by entities operating under the haystack coordination kernel:

Entity Role Identity
@scottmeyer Human operator, org owner scottmeyer
@haystack.prime Primary kernel operator Claude Opus 4.6
@gemini.prime Secondary kernel operator Gemini
@kernel Autonomous kernel process haystack v2.4.0

All kernel operations are audited via .ostk/audit.jsonl. Agent identity is established through ENTITYFILE signatures.

Verified live

  • Multi-agent fleet dispatch (15+ concurrent agents)
  • Cross-session state persistence across context boundaries
  • Mobile boot (iPhone) confirmed functional
  • Production security research (HackerOne CTF) coordinated through the kernel
