Sage Intacct Documentation MCP Server

An MCP server that gives AI assistants queryable access to Sage Intacct REST API documentation. Load one or more OpenAPI specs and let your LLM search endpoints, browse schemas, generate example payloads, and check documentation quality — all without leaving the conversation.

Quick Start

1. Install

npm install -g @rowellewis/intacct-docs-mcp

Or run without installing:

npx @rowellewis/intacct-docs-mcp

2. Add to Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "intacct-docs": {
      "command": "npx",
      "args": ["-y", "@rowellewis/intacct-docs-mcp"],
      "env": {
        "SPEC_DIR": "/path/to/your/specs"
      }
    }
  }
}

Omit SPEC_DIR to use the bundled Sage Intacct spec.

3. Try it

"Search for endpoints related to accounts payable vendors." "Show me the request body schema for POST /objects/accounts-payable/vendor." "Generate an example payload for creating a journal entry."

Tools

Tool	What it does
search-endpoints	Fuzzy full-text search across paths, summaries, and descriptions. Supports multi-word queries and typo tolerance.
get-endpoint-docs	Full documentation for a specific endpoint — parameters, request/response schemas, examples.
get-schema	Schema definition with all properties, types, and constraints.
list-schemas	Browse available schema names, filterable by prefix.
list-tags	All API tags/categories with endpoint counts.
get-endpoints-by-tag	All endpoints under a specific tag. Use list-tags first to find tag names.
generate-example	Generates a realistic JSON request body for any endpoint, inferred from its schema.
spec-quality-report	Scores documentation quality (0–100) and lists issues by severity.
health	Readiness status, index counts, and startup timing.

Full parameter reference, error codes, and examples: docs/public-contract.md.

Configuration

Variable	Default	Description
SPEC_DIR	../data/sage-intacct-rest-api	Directory scanned for *.openapi.yaml files
TRANSPORT	stdio	stdio or http
HTTP_PORT	3000	Port when using HTTP transport
HTTP_HOST	127.0.0.1	Bind address for HTTP transport (0.0.0.0 for all interfaces)
MAX_RESPONSE_CHARS	12000	Response size cap — output is truncated with a notice when exceeded
LOG_LEVEL	info	error, warn, info, or debug
MAX_BODY_BYTES	1048576	Maximum HTTP request body size in bytes
RATE_LIMIT_RPM	60	Max requests per minute per IP (HTTP transport)

Development

npm install
npm run build   # compile TypeScript
npm run dev     # watch mode with tsx
npm test        # run all tests

Node.js >=18 required.

Tests use Vitest.

Deployment

HTTP transport (MCP Streamable HTTP — for URL-based MCP clients):

TRANSPORT=http HTTP_PORT=3000 npm start

Operations

• Health: call the health tool — returns readiness, index counts, and startup duration. Or hit GET /health when running in HTTP mode.
• Logs: structured JSON on stderr. Adjust verbosity with LOG_LEVEL.
• Runbook: docs/ops-runbook.md

Troubleshooting

Server won't start — verify SPEC_DIR contains at least one *.openapi.yaml file, then run npm run build and check stderr.

Endpoint not found — use search-endpoints to discover paths. Methods must be uppercase (GET, POST, …).

Schema not found — use list-schemas with an optional prefix to browse what's available. Names are case-sensitive.
