This server acts as the translation layer between Claude's JSON-RPC tool calls and the [AccuLynx REST API](https://truto.one/integrations/detail/acculynx). You can either build and maintain this infrastructure yourself, or use a managed integration platform like Truto to dynamically generate a secure, authenticated MCP server URL. If your team uses ChatGPT, check out our guide on [/connect-acculynx-to-chatgpt-manage-jobs-leads-and-appointments/](https://truto.one/connect-acculynx-to-chatgpt-manage-jobs-leads-and-appointments/) or explore our broader architectural overview on [/connect-acculynx-to-ai-agents-automate-project-milestones-and-leads/](https://truto.one/connect-acculynx-to-ai-agents-automate-project-milestones-and-leads/). Giving a Large Language Model (LLM) read and write access to a specialized roofing and contractor CRM like AccuLynx is a significant engineering challenge. You must handle complex relational hierarchies (Contacts -> Jobs -> Estimates -> Sections -> Items), manage dynamic payload structures, and deal with AccuLynx's specific pagination constraints. Every time an endpoint shifts or a custom field requirement changes, you have to update your server code, redeploy, and test the integration. This guide breaks down exactly how to use Truto to generate a secure, managed MCP server for the AccuLynx API, connect it natively to [Claude Desktop](https://truto.one/connect-any-api-to-claude-desktop-using-mcp/), and execute complex construction management workflows using natural language. > Want to give your AI agents secure, authenticated access to AccuLynx and 100+ other SaaS APIs? Let's talk about managed MCP architecture. > > [Talk to us](https://truto.one/book-a-demo/) ## The Engineering Reality of the AccuLynx API A custom MCP server is a self-hosted integration layer. While the open MCP standard provides a predictable way for models to discover tools, the reality of implementing it against specialized B2B APIs is painful. AccuLynx is built for contracting workflows, and its API design reflects that domain complexity. If you decide to build a custom AccuLynx MCP server, here are the specific integration challenges you will face: **Nested Resource Hierarchies and Hydration** AccuLynx data is highly relational. A `Job` does not automatically return its full context. To get related data, you must explicitly request hydration using the `includes` query parameter (e.g., `includes=contact,initialAppointment`). If an LLM needs to analyze an estimate, it cannot just call one endpoint; it must fetch the Job, then the Estimate, then the Estimate Sections, and finally the Estimate Items. A custom MCP server must abstract these complex multi-step fetches, whereas a managed platform provides schema-validated tools that explicitly guide the LLM on which required IDs (like `estimate_id` and `estimate_section_id`) to pass. **Draft Endpoints and Shifting Schemas** Many powerful AccuLynx endpoints - such as appointment deletions or specific contact log retrievals - are marked as "draft" by the vendor. This means their request schemas or behavior can change. Hardcoding these endpoints into a static MCP server introduces fragility. If a required field is added to a draft endpoint, your AI agent's tool calls will suddenly fail with HTTP 400 errors until you push a code fix. **Rate Limits and 429 Handling** AccuLynx enforces strict [API quotas](https://truto.one/how-to-handle-api-rate-limits-in-llm-apps/). When building integrations, developers often mistakenly assume their MCP server should silently absorb and retry rate limits. **Truto does not retry, throttle, or apply backoff on rate limit errors.** When the AccuLynx API returns an HTTP 429 (Too Many Requests), Truto explicitly passes that error to the caller. Truto normalizes the upstream rate limit information into standardized IETF headers (`ratelimit-limit`, `ratelimit-remaining`, `ratelimit-reset`). The caller (your agent framework or client) is fully responsible for reading these headers and executing its own backoff strategy. ## Generating the AccuLynx MCP Server Instead of writing and hosting custom Express or FastAPI servers to map AccuLynx endpoints to JSON-RPC 2.0, you can generate a managed MCP server via Truto. This server is dynamically derived from AccuLynx's API documentation and your environment's specific configuration. Truto provides two distinct ways to provision an MCP server: via the dashboard UI or programmatically via the API. ### Method 1: Via the Truto UI If you are setting up an internal tool for your own team, the UI is the fastest path. 1. Navigate to the **Integrated Accounts** page in your Truto dashboard. 2. Select your connected AccuLynx account. 3. Click the **MCP Servers** tab. 4. Click **Create MCP Server**. 5. Select your desired configuration (e.g., restrict to `read` operations or specific tool tags like `financials`). 6. Copy the generated MCP server URL. (e.g., `https://api.truto.one/mcp/a1b2c3d4...`) ### Method 2: Via the API For B2B SaaS platforms provisioning MCP servers on behalf of their customers, use the REST API. This endpoint generates a secure, hashed token in the backend and returns the ready-to-use URL. **Request:** ```bash curl -X POST https://api.truto.one/integrated-account/{integrated_account_id}/mcp \ -H "Authorization: Bearer " \ -H "Content-Type: application/json" \ -d '{ "name": "AccuLynx Financials Agent", "config": { "methods": ["read", "write"] } }' ``` **Response:** ```json { "id": "mcp_srv_99x88y77z", "name": "AccuLynx Financials Agent", "config": { "methods": ["read", "write"] }, "expires_at": null, "url": "https://api.truto.one/mcp/a1b2c3d4e5f6g7h8i9j0" } ``` This URL is fully self-contained. It encodes the tenant connection and the specific tool filters. You do not need to manage AccuLynx OAuth tokens - Truto handles the underlying [API authentication](https://truto.one/how-to-manage-api-authentication-for-ai-agents/) automatically. ## Connecting the MCP Server to Claude Once you have your Truto MCP URL, connecting it to Claude is a straightforward process. You can configure it directly in the Claude UI or via a manual configuration file. ### Method A: Via the Claude UI If you are using the Claude Desktop app or a supported web interface: 1. Open Claude and go to **Settings**. 2. Navigate to **Integrations** or **Connectors**. 3. Click **Add MCP Server** (or Add Custom Connector). 4. Paste your Truto MCP URL into the URL field and provide a name (e.g., "AccuLynx Integration"). 5. Click **Add**. Claude will instantly execute the `initialize` handshake and populate its context window with the available AccuLynx tools. ### Method B: Via Manual Config File If you are running Claude Desktop locally and prefer file-based configuration, you can add the server to your `claude_desktop_config.json` file. Because Truto provides a Server-Sent Events (SSE) endpoint, you must use the standard MCP SSE client wrapper. Open your configuration file (typically located at `~/Library/Application Support/Claude/claude_desktop_config.json` on macOS) and add: ```json { "mcpServers": { "acculynx_prod": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-sse", "--url", "https://api.truto.one/mcp/a1b2c3d4e5f6g7h8i9j0" ] } } } ``` Restart Claude Desktop. The application will boot the SSE client, connect to Truto, and pull the AccuLynx API definitions dynamically. ## AccuLynx Hero Tools for Claude Truto automatically translates AccuLynx API endpoints into descriptive, callable tools with strict JSON schemas. Query parameters and body payloads are flattened into a single intuitive arguments object for the LLM. Here are six high-leverage tools available for AccuLynx automation. ### get_single_accu_lynx_job_by_id Retrieves full context for a specific contracting job. This is the foundational tool for almost all AccuLynx workflows, as you need the `job_id` to lookup financials, estimates, and contacts. You can instruct the agent to use `includes` to fetch nested appointment or contact data simultaneously. > "Fetch the complete job record for job ID 'e591bf22-9828-4144-bca8-42cbb8c6e2c0' and make sure to include the associated contact details in your query." ### list_all_accu_lynx_estimates Fetches paginated estimates across the location or for a specific job. The LLM can use this to review active quotes and pass specific `estimate_id` values to downstream tools that query individual sections or items. > "List all recent estimates for this location. We need to find the specific estimate ID associated with the roof replacement quote from last week." ### list_all_accu_lynx_job_financials Retrieves the core financial data for a specified job. This includes the primary worksheet and any amendments. It is crucial for agents tasked with auditing profitability, checking invoice statuses, or preparing billing summaries. > "Pull the full financial record for job ID 'a1b2c3'. I need you to calculate the total sum of all approved amendments attached to the worksheet." ### create_a_accu_lynx_job_payment_expense Allows the agent to write additional expense line items directly to a job's ledger. The tool schema enforces required fields like amount and date, ensuring the LLM structures the financial payload correctly before executing the POST request. > "Log a new additional job expense of $350.00 for 'Emergency tarping materials' to job ID 'xyz-789'." ### list_all_accu_lynx_latest_scheduled_report_runs Retrieves the most recent instance of an automated scheduled report. This is extremely powerful for analytical agents that need to consume pre-calculated AccuLynx data like weekly sales summaries or production bottlenecks without running raw data queries themselves. > "Check the latest scheduled report run for our 'Weekly Sales by Rep' report (report ID 'rep-123') and summarize the top three performers." ### create_a_accu_lynx_job_document Uploads files (like PDFs, photos, or diagrams) directly to a job's document folder using `multipart/form-data`. Truto handles the complexity of translating the LLM's file request into the correct multipart boundary format required by the AccuLynx API. > "Upload the signed permit PDF to the document folder for job ID 'j-555'. Name the file 'Approved_City_Permit_2026.pdf'."

Instead of manually navigating the AccuLynx UI to piece together data, users can issue natural language commands. Here is how Claude handles real-world scenarios. ### Scenario 1: Auditing Job Financials and Adding Expenses Project managers often need to reconcile material costs against the original job worksheet. > "Review the financials for job ID '77a8b9'. List all current amendments, summarize the worksheet totals, and then add a new $150 expense for 'Rush Delivery Fee'." 1. **`get_single_accu_lynx_job_by_id`**: Claude verifies the job exists and checks its current status. 2. **`list_all_accu_lynx_job_financials`**: Claude retrieves the financial worksheet and the array of existing amendments, summarizing the current profit margin for the user. 3. **`create_a_accu_lynx_job_payment_expense`**: Claude executes the write operation, injecting the $150 expense into the job's payment records. The user receives a clear breakdown of the job's financial health followed by a confirmation that the new expense was successfully logged. ```mermaid sequenceDiagram participant UserUI as User participant Claude as Claude Desktop participant TrutoMCP as Truto MCP Server participant AccuLynx as AccuLynx API UserUI->>Claude: "Review financials for job '77a8b9'..."

Once you have those, grab the latest run of our 'Monthly Sales Volume' scheduled report and compare this job's estimate total to our regional average." 1. **`list_all_accu_lynx_job_estimates`**: Claude fetches the list of estimates tied to the specific job. 2. **`get_single_accu_lynx_estimate_by_id`**: Claude iterates through the returned estimates to fetch the full line-item details and total amounts for the pending quotes. 3. **`list_all_accu_lynx_latest_scheduled_report_runs`**: Claude retrieves the pre-calculated sales data from the scheduled report instance. The user gets a synthesized briefing comparing the specific job's potential revenue against the broader organizational metrics stored in the scheduled report. ## Security and Access Control Exposing an ERP or CRM to an autonomous AI agent requires strict guardrails. Truto's MCP architecture provides multiple layers of access control built directly into the server configuration: * **Method Filtering**: You can configure the server to only allow specific HTTP methods. Passing `"methods": ["read"]` ensures the LLM can only query data (via GET/LIST tools) and physically cannot execute creates, updates, or deletes, preventing accidental record modification. * **Tag Filtering**: AccuLynx tools are grouped logically. You can restrict the MCP server to only expose tools tagged with `financials` or `crm`, keeping the LLM strictly focused on its intended domain. * **API Token Authentication**: By enabling `require_api_token_auth: true`, possession of the MCP URL is no longer enough. The client must also pass a valid Truto API token in the Authorization header, adding a required secondary layer of identity verification. * **Time-Bound Access**: Setting an `expires_at` ISO datetime automatically shreds the MCP server credentials at the specified time. This is perfect for granting temporary agent access to a contractor or auditor. Building an AI agent integration with AccuLynx doesn't require reverse-engineering their API, dealing with their draft schemas, or building custom rate limit logic. By generating a managed Truto MCP server, you can give Claude instant, secure, and structurally sound access to your contracting data.
