niceassos-mesh-mcp

MCP server for foldkit — exposes the 7-prime spine, 7 κ-bands, and 6 fold operations as native tools + resources in any MCP client (Claude Code, Claude Desktop, Cursor, Cline, Windsurf, etc.).

Second canonical exemplar of the AI-Native Solutions estate -mcp companion shape. Fork this repo verbatim to build companions for any of the ~295 estate substrates.

      "args": ["-y", "@ai-native-solutions/niceassos-mesh-mcp"]
    }
  }
}

Cursor

Create or edit .cursor/mcp.json:

{
  "mcpServers": {
    "foldkit": {
      "command": "npx",
      "args": ["-y", "@ai-native-solutions/niceassos-mesh-mcp"]
    }
  }
}

Cline / Windsurf

Add to your MCP settings JSON:

Tools exposed (10)

Tool	Purpose
`foldkit_fold_number`	7-vector → primorial fold + signature
`foldkit_unfold_state`	fold integer → 7-vector via 7-prime factorisation
`foldkit_depth_band`	κ → named band (ground / perception / gate / heart / naming / recognition / collapse)
`foldkit_classify_kappa_band`	free-text utterance → κ band via marker phrases
`foldkit_apply_op`	apply fire / water / void / thunder / echo / flower to a state
`foldkit_kawasaki_check`	flat-fold angle sum check
`foldkit_maekawa_check`	mountain-valley parity check ( \| M − V \| = 2 )
`foldkit_signal_survival`	κ^depth signal survival + %
`foldkit_unclog_gain`	gain from clearing N layers of a κ stack
`foldkit_probe_from_kappa`	κ or text → band + routing op + probe question

Resources exposed (4)

URI	Payload
`foldkit://spine`	7-prime spine with glyphs + names + ISA-95 layer mapping
`foldkit://kappa-bands`	7-band κ definitions (bounds · glyph · ring · warn / orphan flags)
`foldkit://ops`	6 fold operations (kanji · arrow · verb · probe)
`foldkit://constants`	φ · κ · Ω · θ · θ_step · BASELINE

Example prompts (once installed)

"Fold the state [1,0,2,0,0,1,0] using foldkit."
"What κ-band is this text in: 'I notice I'm feeling stuck'?"
"Apply the fire op to ring 3 of the baseline state."
"Read foldkit://spine and explain the ISA-95 mapping."
