Sf Documentation Knowledge

Collect, process, and serve Salesforce documentation for LLM agents — using Context Engineering + MCP, not RAG.

---

Overview

This system programmatically collects all Salesforce documentation from developer.salesforce.com (129 domains, 35,000+ pages), processes it into structured, curated knowledge files, and serves them to LLM agents via:

1. Context Engineering — Pre-compiled Markdown files with _index.md routing tables
2. MCP Server — 12 tools + 4 prompts + 5 resources via Model Context Protocol
3. Knowledge Graph — 53,000+ nodes and 450,000+ edges connecting SF concepts, namespaces, services, and cross-references

No embeddings. No vector stores. No blind chunking.

Quick Start

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "sf-docs": {
      "command": "npx",
      "args": ["-y", "-p", "@sfdxy/sf-documentation-knowledge", "sf-docs-mcp"],
      "env": {
        "SF_ACTIVE_DOMAINS": "apex-guide,apex-reference,lwc"
      }
    }
  }
}

Remove the env block to search all 129 domains. See Domain Restriction for details.

Restart Claude Desktop.

VS Code (GitHub Copilot)

Add to .vscode/mcp.json in your workspace (or globally in VS Code settings):

{
  "servers": {
    "sf-docs": {
      "command": "npx",
      "args": ["-y", "-p", "@sfdxy/sf-documentation-knowledge", "sf-docs-mcp"],
      "env": {
        "SF_ACTIVE_DOMAINS": "apex-guide,apex-reference,lwc"
      }
    }
  }
}

Then use @sf-docs in Copilot Chat to query Salesforce documentation.

Gemini Code Assist / Gemini CLI

Add to your MCP config (~/.gemini/settings.json or project .gemini/settings.json):

{
  "mcpServers": {
    "sf-docs": {
      "command": "npx",
      "args": ["-y", "-p", "@sfdxy/sf-documentation-knowledge", "sf-docs-mcp"],
      "env": {
        "SF_ACTIVE_DOMAINS": "apex-guide,apex-reference,lwc"
      }
    }
  }
}

Cursor

Add in Settings -> MCP Servers -> Add Server:

• Name: sf-docs
• Command: npx -y -p @sfdxy/sf-documentation-knowledge sf-docs-mcp
• Transport: stdio
• Environment: SF_ACTIVE_DOMAINS=apex-guide,apex-reference,lwc

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "sf-docs": {
      "command": "npx",
      "args": ["-y", "-p", "@sfdxy/sf-documentation-knowledge", "sf-docs-mcp"],
      "env": {
        "SF_ACTIVE_DOMAINS": "apex-guide,apex-reference,lwc"
      }
    }
  }
}

OpenCode

Add to your OpenCode config (~/.config/opencode/config.json or project .opencode/config.json):

{
  "mcpServers": {
    "sf-docs": {
      "command": "npx",
      "args": ["-y", "-p", "@sfdxy/sf-documentation-knowledge", "sf-docs-mcp"],
      "env": {
        "SF_ACTIVE_DOMAINS": "apex-guide,apex-reference,lwc"
      }
    }
  }
}

Any MCP Client (Generic)

Point your MCP client to:

npx -y -p @sfdxy/sf-documentation-knowledge sf-docs-mcp

The server uses stdio transport and is compatible with any MCP client.

Why -p + sf-docs-mcp?
The package ships two binaries: sf-knowledge (the data pipeline CLI) and sf-docs-mcp (the MCP server). Using -p installs the package and then explicitly calls the sf-docs-mcp binary, ensuring you get the MCP server and not the CLI.

Use from Source

git clone https://github.com/Avinava/sf-documentation-knowledge.git
cd sf-documentation-knowledge
npm install
npm run build
npm run mcp:start

---

MCP Server

The MCP server loads the full 53k-node knowledge graph and 18,000+ code snippets into memory on startup (~5s) and serves all queries instantly.

Run directly from source:

npm run mcp:start

Or via npx (no clone required):

npx -y -p @sfdxy/sf-documentation-knowledge sf-docs-mcp

sf_semantic_search	AI-powered semantic search with NLP query understanding	"how to process records in bulk"
sf_read_topic	Read a specific documentation topic's content	Read the SOQL reference page
sf_graph_query	Navigate the knowledge graph — related docs, namespaces, services	"Show all docs in the System namespace"
sf_list_domains	List all available domains, filter by service category	"List analytics domains"
sf_apex_lookup	Look up an Apex class with full documentation	"Look up the String class"

sf_set_active_domains	Restrict all tools to specific documentation domains	Focus on revenue-cloud only
sf_suggest_domains	Suggest relevant domains for a task description	"contract lifecycle management"

Prompt Templates (4)

Prompt	What It Does	Arguments
explore_api	Walk through a Salesforce API — endpoints, auth, best practices	api: API name (e.g., "REST API")
debug_apex	Debug an Apex issue — class lookup, error patterns, examples	topic: class/error (e.g., "System.QueryException")
compare_services	Compare Salesforce products by documentation coverage	services: categories (e.g., "analytics vs commerce")
write_apex	Write production-ready Apex — gathers limits, patterns, examples first	task: what to build (e.g., "batch job to update Accounts")

Resources (5)

Agents can read these without making a tool call:

Resource URI	Content
sf://overview	System stats, available tools, quick start guide
sf://domains	All documentation domains with descriptions
sf://namespaces	All Apex namespaces with doc counts
sf://services	All service categories with domain counts
sf://config	Current domain restriction state and runtime controls

---

Domain Restriction

When working on a specific Salesforce product area (e.g., Revenue Cloud, Apex development), you can restrict all tools to only search within relevant domains. This reduces noise and improves result quality.

How It Works

• At startup: Set SF_ACTIVE_DOMAINS as a comma-separated list of domain IDs in your MCP client config
• At runtime: Use sf_set_active_domains to change the active domains without restarting
• Not set: All 129 domains are searched (default, no breaking change)
• Per-call domain filter outside active set: Returns empty results with a warning (not an error)
• sf_read_topic outside active set: Shows a gentle note but still allows reading

Discovering Domains

# Let the AI suggest domains for your task
sf_suggest_domains("building LWC components with Apex backend")
→ Suggests: lwc, apex-guide, apex-reference, lightning

# Set the suggested domains
sf_set_active_domains(domains: ["lwc", "apex-guide", "apex-reference", "lightning"])

# Check current state
sf_set_active_domains()

# Clear restrictions
sf_set_active_domains(clear: true)

Behavior by Tool

Tool	Domain Restriction Behavior
sf_search	Filters via Orama where clause + keyword fallback filtering
sf_semantic_search	Filters via Orama where clause on expanded + original queries
sf_code_examples	Filters via CodeIndex domains[] parameter
sf_graph_query	Post-filters related, namespace, context, search results
sf_explain_error	Domain-aware search + post-filtered keyword results
sf_apex_lookup	Warns if apex-reference/apex-guide not in active set
sf_object_reference	Warns if sfFieldRef/object-reference not in active set
sf_list_domains	Shows all domains, marks active ones with checkmark
sf_read_topic	Gentle warning (still allows reads outside active set)
sf_limits	No filtering (hardcoded data, no graph search)

All 129 Domain IDs

See docs/domains.md for the full list organized by service category, or use sf_list_domains at runtime.

Knowledge Base

The repository comes pre-loaded with 35,000+ curated markdown files and a Knowledge Graph (53,000+ nodes, 450,000+ edges) covering 129 domains of Salesforce documentation.

Option A: Context Engineering (File-based)

Point your AI agent to the _index.md file in any domain folder. The index acts as a routing table telling the AI which files contain which topics:

knowledge/current/<domain-name>/_index.md

Each domain folder also has a SKILL.md in skills/<domain-name>/SKILL.md that teaches AI agents how to navigate the knowledge.

Option B: Knowledge Graph

The graph at knowledge/current/graph.json connects all documentation with semantic relationships:

Edge Type	What It Connects
references	Document → Document (52,988 cross-references)
belongs_to_namespace	Document → Apex Namespace (143 namespaces)
belongs_to_service	Domain → Service Category (16 categories)
is_type	Document → DocType (api-reference, developer-guide, concept, etc.)
tagged_with	Document → Keyword (22,610 unique keywords)
contains	Domain → Document

Inspect it with:

npm run graph:stats

See Graph Schema Documentation for the full schema with node/edge types, ID conventions, and a visual diagram.

Data Pipeline

To update the knowledge base with the latest Salesforce releases, run the pipeline in order:

Step 1: Discover Available Deliverables

npm run discover

Lists all documentation deliverables available from the Salesforce Index API (~127 deliverables).

Step 2: Collect Raw Data

# Collect a specific domain
npm run collect -- --domain cli-commands

# Collect all configured (P0) domains
npm run collect

# Collect ALL deliverables from the SF index API (121 domains, ~31k pages)
npm run collect -- --discover

Step 3: Process HTML to Markdown

# Process a specific domain
npm run process -- --domain cli-commands

# Process ALL collected domains
npm run process -- --discover

Automatically cleans HTML, strips noise, parses tables, formats code blocks, creates clean Markdown, and redacts any Salesforce tokens or secrets.

Step 4: Generate Knowledge Files & Graph

# Generate ALL collected domains and rebuild the full Knowledge Graph
npm run generate -- --discover

Builds the knowledge graph (cross-references, namespaces, service categories, doctype clustering), generates context files, and updates inventory docs.

Step 5: Inspect the Graph

npm run graph:stats

Full Pipeline (One-liner)

npm run collect -- --discover && npm run process -- --discover && npm run generate -- --discover

---
