mcp-tripartite

mcp-tripartite is a skill for Codex from plurigrid/asi. It costs 0 tokens per session (2,519 once invoked), scanned B, original, MIT.

A set of rules for connecting MCP servers—services that let an agent call external tools—with paired validation and generation skills. It describes a three-part structure using GF(3), a mathematical three-state balancing scheme.

In plain words
What is it for?
Use it when configuring the listed MCP integrations, checking their assigned complementary skills, or exploring the shown color-generation and validation calls.
Why use it?
It provides a prescribed way to organize and validate MCP integrations, though the excerpt does not explain a general user task it solves.

Skill for Codex

Written for Codex: reads ~/.codex or $CODEX_HOME. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

mcp-tripartite scanned grade B with 1 finding 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 8d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

SKILL: MCP Tripartite Integration

Version: 1.0.0 Trit: 0 (ERGODIC) Domain: mcp, integration, orchestration


Overview

Each MCP server is integrated with a 3-partite structure that ensures GF(3) conservation:

MCP_server ⊗ Skill_MINUS ⊗ Skill_PLUS = 0 (mod 3)

This creates balanced triads where each MCP has a validator (-1) and generator (+1) complement.


MCP Tripartite Assignments

1. GAY.jl MCP (Trit: 0)

three-match (-1) ⊗ gay (0) ⊗ cider-clojure (+1) = 0 ✓
Role Component Action
MINUS three-match Validate GF(3) conservation
ERGODIC gay-mcp Generate deterministic colors
PLUS cider-clojure Interactive REPL exploration

Integration Pattern:

# Generate color via gay-mcp
color = mcp_call(:gay, :generate_color, seed: 0x42D)

# Validate with three-match
valid = mcp_call(:gay, :verify_gf3, colors: [c1, c2, c3])

# Explore in cider-clojure
(mcp/gay :generate-palette {:seed 1069 :count 12})

2. Firecrawl MCP (Trit: +1)

tree-sitter (-1) ⊗ babashka (0) ⊗ firecrawl (+1) = 0 ✓
Role Component Action
MINUS tree-sitter Parse/validate scraped content structure
ERGODIC babashka Transform scraped data
PLUS firecrawl Scrape web content

Integration Pattern:

;; Scrape with firecrawl
(def content (mcp/firecrawl :scrape {:url "https://example.com"}))

;; Parse with tree-sitter
(def ast (mcp/tree-sitter :get_ast {:content content :language "html"}))

;; Transform with babashka
(bb/transform ast {:extract [:title :links :code-blocks]})

3. Exa MCP (Trit: +1)

radare2 (-1) ⊗ huggingface (0) ⊗ exa (+1) = 0 ✓
Role Component Action
MINUS radare2 Deep binary/code analysis
ERGODIC huggingface Model/paper discovery
PLUS exa AI-powered search

Integration Pattern:

# Search with exa
results = mcp_call("exa", "web_search_exa", query="LLVM optimization passes")

# Find related papers on huggingface
papers = mcp_call("huggingface", "paper_search", query="compiler optimization")

# Analyze binaries with radare2 (for found libraries)
analysis = mcp_call("radare2", "analyze", level=2)

Changes

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-tripartite is a skill published in the GitHub repository plurigrid/asi (62 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,519 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
