What is rdl-mcp CLAUDE.md?

Project instructions for RDL MCP Server, a tool that lets AI assistants read and change SSRS report files. SSRS is Microsoft's system for creating and publishing reports, and RDL is its report-file format.

Use them when changing report operations, running the server, or testing all, individual, or specific groups of report tests.

They explain how the server handles requests and how to test report changes without manually editing complex XML.

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	$0.00699	$0.00699
Opus 5.5	$0.00280	$0.00280

Security

Grade A, and why

rdl-mcp 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.

Project Overview

RDL MCP Server is a Model Context Protocol (MCP) server that enables AI assistants to read and modify SSRS (SQL Server Reporting Services) RDL files. It provides simple JSON-based tools instead of requiring direct XML manipulation of complex RDL structures.

Build and Test Commands

# Run all tests
python3 -m pytest tests/ -v

# Run a single test file
python3 -m pytest tests/test_rdl_mcp_server.py -v

# Run a specific test class
python3 -m pytest tests/test_rdl_mcp_server.py::TestColumnOperations -v

# Run a specific test
python3 -m pytest tests/test_rdl_mcp_server.py::TestColumnOperations::test_update_column_header -v

# Run the server directly (for testing)
python3 rdl_mcp_server.py

# Install with uv (preferred)
uvx rdl-mcp

Architecture

The codebase follows a modular design with the main MCP server delegating to specialized modules:

rdl_mcp_server.py - Entry point with logging setup, imports MCPServer from package
rdl_mcp/server.py - Core MCPServer class handling JSON-RPC protocol, tool registration, and request routing
rdl_mcp/reader.py - Read-only operations: describe_rdl_report, get_rdl_datasets, get_rdl_parameters, get_rdl_columns
rdl_mcp/columns.py - Column modifications: add/remove/update header/width/format
rdl_mcp/datasets.py - Dataset operations: add/remove fields, update stored procedures
rdl_mcp/parameters.py - Parameter operations: add/update report parameters
rdl_mcp/validation.py - RDL validation and field reference extraction
rdl_mcp/xml_utils.py - Shared XML parsing utilities and namespace handling

Key Constraints

Python standard library only - No external dependencies beyond pytest for testing
Python 3.8+ compatibility required
Tablix controls only - Currently supports table-based reports, not Matrix or Chart controls
RDL 2016 namespace - Uses http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition

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.
