bc_run_report

Execute Business Central reports by numeric ID to run server-side actions, inspect request-page parameters, or capture rendered PDF, Excel, or Word output.

Instructions

Execute a Business Central report by its numeric report ID. If the report has a request page (parameter/filter dialog), the response's requestPage carries its fields plus a requestPage.pageContextId and requestPage.formId. Fill parameters with bc_write_data against that pageContextId, then run the report with bc_respond_dialog { dialogFormId: requestPage.formId, response: "ok" }. The report runs server-side on the BC service tier.

Pass format: "pdf", "excel", or "word" to capture the rendered output as base64-encoded bytes (this path auto-drives the request page, so no bc_write_data/bc_respond_dialog is needed). The tool drives the BC "Send to..." flow (SystemAction 410) internally: opens the format-selection dialog, selects the requested format by SaveValue-ing the matching text label into the SelectionControl, confirms with OK (300), then fetches the file from DynamicFileHandler.axd. When format is set, rendered file bytes are returned in downloads[] (base64 in bytes, or savedPath when BC_DOWNLOAD_DIR is set); an oversized file reports a per-entry error instead of bytes.

Format availability depends on the report's installed layouts -- not all reports offer all three formats. If the report does not offer the requested format, an error is returned listing the available option texts. "pdf" is always BC's default and requires no SaveValue; "excel" prefers the "data only" variant; "word" targets any option containing "Word".

Use this tool for reports that perform server-side actions (batch posting via Report 295, inventory adjustments, data processing) or to inspect and fill request page parameters. Common reports: 1306 (Customer Statement), 120 (Aged Accounts Receivable), 6 (Trial Balance), 295 (Batch Post Sales Orders).

Do NOT use this for viewing data -- use bc_open_page and bc_read_data for data retrieval. Do NOT confuse reports with pages -- reports are processing/printing objects, pages are UI views.

Example (open request page): { "reportId": 6 } Example (capture PDF): { "reportId": 6, "format": "pdf" } Example (capture Excel): { "reportId": 6, "format": "excel" } Example (capture Word): { "reportId": 6, "format": "word" }

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
formatNoRendered output format to capture via the BC "Send to..." flow. "pdf" captures a PDF (BC default); "excel" captures Excel (prefers "data only" layout); "word" captures a Word document. Format availability depends on the report's installed layouts -- reports without the requested layout return an error listing available formats. Omit to open the request page only without executing.
reportIdYesNumeric BC report ID to execute (e.g., 1306 for Customer Statement, 6 for Trial Balance).

A5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden, and it delivers: it discloses server-side execution, internal driving of the BC 'Send to...' flow (SystemAction 410), request-page auto-driving when format is set, oversized-file error behavior, and layout-dependent format availability. This is a high-transparency description for a complex mutation-like tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but every section earns its place: summary, request-page workflow, format mechanics, layout caveats, usage boundaries, and concrete examples. The structure front-loads the core behavior and then layers detail logically, making it easy for an agent to extract the critical decision points quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given there is no output schema, the description adequately explains return behavior (downloads[] with base64 bytes or savedPath, oversized-file errors, requestPage details). It also covers edge cases like unavailable formats and defaults, making it complete enough for an agent to invoke the tool correctly in most scenarios.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Although input schema coverage is 100%, the description adds substantial meaning beyond the schema: examples of valid invocations, what omitting format does, how format maps to BC's 'Send to...' flow, and how errors surface when a format is unavailable. This goes well beyond the baseline set by the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action—execute a Business Central report by numeric report ID—and clearly distinguishes reports from pages and from data-viewing tools. It also names sibling tools (bc_open_page, bc_read_data) as the alternatives for data retrieval, so the tool's role is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says when to use this tool (server-side report actions, inspecting/filling request page parameters) and when not to use it (viewing data—use bc_open_page/bc_read_data instead). It also provides common report IDs and explains the format-selection behavior, leaving little ambiguity about correct invocation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
