Cline

This guide explains how to configure Cline to work with the PwC AI-CoE Coding Agents Gateway.

Overview

Cline is a VS Code extension that supports multiple LLM providers. This guide covers configuration using the OpenAI-compatible API endpoint.

Base URL Configuration

In Cline's API Configuration panel, set the Base URL to:

https://idi-coding-agents.pwc.it

Cline automatically appends /chat/completions to this URL when making requests.

Network Requirements

The endpoint https://idi-coding-agents.pwc.it is only accessible via PwC VPN set to Italy or Italy On-Premise.

An alternative endpoint (https://doc-interact-backend.pwc.it) is available on the public internet and can also be used as the Base URL, but is not recommended as it's protected by the Imperva firewall, which may block frequent requests from coding agents, interpreting them as DDoS attempts.

API Key Configuration

In the OpenAI Compatible API Key field, enter your credentials in the following format:

apikey=<your-api-key>&tenantid=<your-tenant-id>

Replace <your-api-key> and <your-tenant-id> with the values obtained as described in Get Access.

The gateway parses this string from the Authorization: Bearer header that Cline sends automatically.

Why this format?

Some Cline versions have a known issue where Custom Headers are intermittently dropped from requests, causing authentication failures. Using the API Key field with the apikey=...&tenantid=... format is more reliable because it goes through the standard Authorization header, which is always sent.

Custom Headers

In the Custom Headers section, add the following entry:

Header	Value
model-name	Model identifier — accepts any of the three formats: vendor naming convention (e.g., claude-sonnet-4-6), Coding Agents Gateway naming convention (e.g., GENAI_SHARED_VERTEXAI_ANTHROPIC_CLAUDE_46_SONNET), or PwC GenAI Shared Service naming convention (e.g., vertex_ai.anthropic.claude-sonnet-4-6). See Available Models for all values.

note

You no longer need api-key, tenant-id, or auth-type custom headers if you configured the API Key field as described above.

Model Configuration

Important: Set Max Output Tokens

Cline does not auto-detect model limits. You must manually set Max Output Tokens (and Context Window Size) in the MODEL CONFIGURATION section, otherwise Cline will use incorrect defaults and may truncate responses or fail.

In the MODEL CONFIGURATION section, set the following parameters to match your chosen model:

Parameter	Value
Context Window Size	Value from the Available Models table
Max Output Tokens	Value from the Available Models table

Optional: Cost Tracking

To monitor conversation costs, you can also configure:

Parameter	Value
Input Price / 1M Tokens	Value from the Available Models table
Output Price / 1M Tokens	Value from the Available Models table

tip

Leave the Temperature parameter at its default value for optimal results.
