What is procore-mcp-server CLAUDE.md?

Instructions for a TypeScript server that connects Claude Code to Procore, a construction-management platform, through its REST API, a standard way for software to exchange data.

Use them to discover Procore API categories and endpoints, inspect parameters, make API calls, and configure company and project settings.

They explain how to install, build, authenticate, and use the server instead of requiring developers to infer its setup and API structure.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02345	$0.02345
Opus 5.5	$0.00938	$0.00938
Sonnet 5.5	$0.00469	$0.00469
Haiku 4.5	$0.00234	$0.00234

Security

Grade A, and why

procore-mcp-server CLAUDE.md scanned grade A with 0 findings 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Procore MCP Server

MCP server exposing the full Procore REST API for Claude Desktop and Claude Code. Single-user OAuth. TypeScript + @modelcontextprotocol/sdk.

Quick Start

npm install
npm run build          # Generate catalog from OAS + compile TypeScript
npm run auth           # One-time: OAuth flow to get Procore tokens
npm start              # Start MCP server (stdio transport)

Architecture

7 MCP tools provide full coverage of Procore API endpoints:

Tool	Purpose
`procore_discover_categories`	List API categories with endpoint counts
`procore_discover_endpoints`	List endpoints in a category/module
`procore_get_endpoint_details`	Get full parameter schema for an endpoint
`procore_api_call`	Execute any Procore API call
`procore_search_endpoints`	Full-text search across endpoints
`procore_get_config`	Show current config (company_id, auth status)
`procore_set_config`	Set runtime config (company_id, project_id)

Build Pipeline

specs/combined_OAS.json (~54MB) -> scripts/generate-catalog.ts -> data/catalog.json + data/endpoint-details/ -> scripts/generate-tools-manifest.ts -> data/tools-manifest.json

Current spec (2026-08-04): 3,155 operations -> 2,929 generated tools + 7 meta tools. The manifest drops older-version duplicates of the same path and the non-callable /oauth/* endpoints; both stay reachable via procore_api_call.

Tool Description Quality

Generated tool descriptions are assembled from one sentence per scoring dimension, and no sentence may restate another:

Module	Responsibility
`src/tools/resource-label.ts`	Names the actual resource from the OAS summary (never the category)
`src/tools/purpose-builder.ts`	Verb-aware purpose synthesis (a reorder is never described as a create)
`src/tools/description-builder.ts`	Deprecation notice, usage guidance, prerequisites, assembly
`src/tools/behavior-builder.ts`	Return shape, side effects, failure modes
`src/tools/param-descriptions.ts`	Per-parameter prose and source hints
`src/tools/annotation-builder.ts`	Titles and MCP annotations
`src/tools/version-sibling-note.ts`	Names cross-version sibling tools in the description

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.
