DeepWiki MCP Skill

AI-powered documentation and Q&A for any public GitHub repository

Version: 1.0.0 Trit: 0 (Ergodic - coordinates knowledge retrieval) Bundle: research Provider: Cognition (Devin AI) - Official, Free, No Auth Required

Overview

DeepWiki MCP provides programmatic access to AI-generated documentation for any public GitHub repository indexed on DeepWiki.com. It enables:

1. Wiki Structure: Get table of contents for any repo's documentation
2. Wiki Contents: Read AI-generated documentation for specific topics
3. Ask Questions: Get AI-powered answers grounded in repository context

Server Configuration

Base URL

Wire Protocols

Tools

1. read_wiki_structure

Get the documentation topic tree for a GitHub repository.

{
  "tool": "read_wiki_structure",
  "params": {
    "repo_owner": "AlgebraicJulia",
    "repo_name": "ACSets.jl"
  }
}

Returns: List of documentation topics/sections

2. read_wiki_contents

Read documentation for a specific topic.

{
  "tool": "read_wiki_contents",
  "params": {
    "repo_owner": "AlgebraicJulia",
    "repo_name": "ACSets.jl",
    "topic": "Overview"
  }
}

Returns: AI-generated documentation content

3. ask_question

Ask any question about a repository with AI-powered, context-grounded response.

{
  "tool": "ask_question",
  "params": {
    "repo_owner": "AlgebraicJulia",
    "repo_name": "Catlab.jl",
    "question": "How do wiring diagrams compose?"
  }
}

Returns: AI-powered answer with repository context

Use Cases

1. Understand New Libraries

"Read the documentation structure for react/react and explain the hooks system"

2. Answer Technical Questions

"How does Catlab.jl implement natural transformations?"

3. Compare Implementations

"Compare how ACSets.jl and Catlab.jl handle graph homomorphisms"

4. Explore Category Theory Libraries

"What topics are covered in AlgebraicJulia/AlgebraicDynamics.jl documentation?"

Indexing Your Repository

To make your public GitHub repo available via DeepWiki MCP:

1. Visit DeepWiki.com
2. Enter your repository URL
3. Wait for indexing to complete
4. Add the DeepWiki badge to your README:

ACSet Skill Integration

Both deepwiki-mcp and acsets-algebraic-databases are ERGODIC (trit 0) — they substitute for each other in triads and coordinate knowledge transport.

Qualified Workflow

Verified DeepWiki ↔ ACSets Correspondence

Cross-Skill Examples

Example 1: ACSets + Catlab.jl

# 1. Query DeepWiki for oapply semantics
mcp__deepwiki__ask_question("AlgebraicJulia/Catlab.jl", 
  "How does oapply compose undirected wiring diagrams?")

# 2. Apply via ACSets skill patterns
@present SchUWD(FreeSchema) begin
  Box::Ob; Port::Ob; Junction::Ob; OuterPort::Ob
  box::Hom(Port, Box)
  junction::Hom(Port, Junction)
  outer_junction::Hom(OuterPort, Junction)
end

# 3. oapply = colimit of component diagram (verified by DeepWiki)
composite = oapply(wiring_diagram, components)

Example 2: DisCoPy for Quantum/Categorical Diagrams

# Query DisCoPy documentation
mcp__deepwiki__ask_question("discopy/discopy",
  "How do monoidal categories compose with tensor products?")

# DisCoPy has 23 pages covering:
# - Monoidal, Rigid, Symmetric, Frobenius categories
# - Quantum circuits and gates
# - QNLP (Quantum Natural Language Processing)
# - Tensor network backends

Example 3: Agent-o-rama for Rama Integration

;; Query agent-o-rama patterns
mcp__deepwiki__ask_question("redplanetlabs/agent-o-rama",
  "How do PStates store agent invocation state?")

;; 28 pages covering:
;; - Agent Modules and Topology
;; - PStates and Depots storage
;; - Tool Calling Integration
;; - Human-in-the-Loop Workflows
