Connect your agent.

33 tools: connect the complete collection, a category or a single tool.

Connection

All-tools endpoint: https://tools.tarsolution.com/mcp
Transport: Streamable HTTP · Protocol: 2025-11-25
No API key is required for public access.

Enter an endpoint below as your client's MCP server URL. Discover tools with tools/list and execute them with tools/call. Each endpoint lists and accepts only its own tools. Avoid connecting overlapping scopes, which can duplicate definitions in your client.

Category endpoints

Individual tools and benefits

These are qualitative expectations, not measured savings. Token usage includes definitions, arguments, results, reasoning and retries. Focused endpoints help when the client loads fewer definitions; clients with dynamic discovery may already do this. Large documents can increase consumption.

Green indicates high potential; lime, amber and orange mark workflow, input and output dependencies; red means limited token-saving potential, not low tool quality. Conditional labels describe different dependencies, not measured savings ranks.

Output and token use

Connection and call examples

For clients accepting an mcpServers configuration, use the following URL entry. Client-specific configuration may differ. Replace the URL with a category or single-tool endpoint from the tables above.

{
  "mcpServers": {
    "tarsolution": {
      "url": "https://tools.tarsolution.com/mcp/category/engineering"
    }
  }
}

Protocol example: POST these JSON bodies to the same endpoint with Content-Type: application/json and Accept: application/json, text/event-stream. After initialization, include MCP-Protocol-Version: 2025-11-25.

1. Initialize:

{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"example-agent","version":"1.0"}}}

2. Notify initialization, then discover tools in a separate POST:

{"jsonrpc":"2.0","method":"notifications/initialized"}

{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}

3. Decode a Modbus RTU request through the engineering endpoint or https://tools.tarsolution.com/mcp/tool/modbus-parser:

{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"modbus-parser","arguments":{"mode":"frames","frame_payload":"01 03 00 00 00 0A C5 CD","transport":"rtu","message_type":"request","validate_crc":true}}}

The response's result.content[0].text contains this compact JSON report. Its inner result is the tool data; insights preserves CRC diagnostics:

{"result":{"unit":1,"function":3,"data_hex":"00 00 00 0a","start_address":0,"quantity":10},"insights":["CRC: passed"]}

Example agent requests: “Decode this RTU frame and check its CRC”; “Calculate AGA8 properties for 90% methane, 6% ethane and 4% nitrogen”; or, using the networking scope, “Look up example.com through RDAP and report the source.” Scope endpoints only allow the tools listed within them.

MCP returns text content blocks. JSON reports use compact serialization and retain relevant insights, verification status and diagnostics. Visual HTML and embedded preview images are omitted. Each tool declares an outputSchema and returns matching structuredContent alongside the existing text result. The 64 KiB result limit includes both representations. Select concise output formats where available. No token reduction percentage has been measured: compare successful tasks using the same model, input and accuracy requirements. Byte size is not a token count.

Capabilities and authorization

REST Send can change remote data and requires accept_terms: true; SSO client-credentials calls also require explicit authorization. Keep client permission controls enabled. Existing destination restrictions and quotas apply. Certificate MCP supports public certificate/CSR inspection only; key generation remains browser-local. Preview tools return source, not rendered images. Webhook MCP returns relative callback/event paths: resolve them against the site origin and subscribe to the separate event stream before sending. MCP does not collect webhook events.

Public usage limits

• 10 requests per minute per IP address.
• 60 requests per minute globally, shared with public diagnostics.
• 4 concurrent operations in the shared pool.
• 12-second execution deadline and 64 KiB maximum MCP result.

All scopes share these quotas; switching endpoints does not bypass them. Discovery counts toward limits. REST also retains its destination quotas. MCP requests are limited to 256 KiB. Oversized results are rejected, not silently truncated. Rate limiting returns HTTP 429; unavailable quota service returns 503.

JSON-RPC POST supports initialize, ping, tools/list and tools/call. Standalone MCP SSE and sessions are unsupported: SSE GET returns 405. Browser visits redirect here; unknown scopes return 404.

Privacy policy

Tool data and service logs

Tool inputs and results are processed to perform the operation you request and are not persisted by this service. The production service retains anonymized HTTP access logs for 7 days for service operation and troubleshooting. No other service logs are retained. We do not keep personal user activity logs. Webhook events are not saved or replayed; anyone with a webhook channel URL can send or observe events.

Sharing and external services

Results are returned to the client that requested them. When you use a network tool, the requested destination receives the data needed for that operation, such as a domain, URL, API request or explicitly supplied credential. Destination providers apply their own privacy policies. Your agent provider, including ChatGPT, may retain prompts, tool arguments and results under its own settings and policies. Avoid sending unnecessary personal information or secrets.

Website analytics

The website uses Google Analytics 4 to understand visits and tool-page usage through anonymous usage statistics. Its browser integration uses analytics cookies and sends page-usage information to Google; cookie identifiers can distinguish browser visits. It does not read tool inputs or results, omits query strings and fragments from page locations, and disables Google Signals and advertising personalization. Direct MCP requests do not execute this browser analytics integration. Analytics statistics are stored in Google Analytics according to that property's retention settings; the 7-day HTTP log retention period does not apply to Google Analytics.

Your choices and requests

You can stop using the service, disconnect it from your agent, and block analytics scripts or cookies with your browser controls. Clearing cookies removes those stored in your browser, but does not by itself delete information already held by Google Analytics. The website's cookie notice is informational: dismissing it does not disable analytics. See cookies and analytics for details.

Send privacy, access or deletion requests to contact@fmarslan.com. Please identify the relevant service and approximate time without resending secrets. We will explain what information can be located and the available action; anonymized records may not be attributable to an individual. For data retained by your agent provider or a requested destination, use that provider's privacy controls as well.
