v1.10.1ISC

Operate Microsoft Fabric, Power BI, and Power Automate through a native portable MCP server.

Changelog

1.10.1 - 2026-11-08

  • Include third-party dependency license and notice files with the bundled Windows executable. The executable remains the official v1.10.0 artifact.

1.10.0 - 2026-10-12

  • Add pipeline and Copy Job creation, metadata retrieval/update, and reviewed deletion.
  • Add full Copy Job definition retrieval and guarded mapping/property patches.
  • Add bounded connection discovery with metadata projection and no credential values.
  • Retain the pipeline activity patch contract. Shared item locks cover definition edits, metadata updates and deletion.
  • Bind confirmed applies to reviewed hashes, submit each mutation once, and verify readback. Uncertain creates never retry automatically.
  • Deletion exports recovery material and blocks on runs, schedules, known references or incomplete scoped checks. No permanent deletion, implicit execution or scheduling.
  • Expose 74 canonical / 56 read-only tools. Live lifecycle verification remains separate.

1.9.0 - 2026-10-06

  • Add fabric_apply_notebook_patch for ordered code/Markdown cell insertion, source/type updates, removal and reordering. Existing source-only edits stay compatible.
  • Preview cell counts, order, types and discarded field names. Type conversions require explicit opt-in before discarding populated incompatible outputs or attachments.
  • Preserve metadata, bindings, parameter tags, existing IDs and unrelated definition parts. New cell IDs are deterministic; Fabric notebooks with missing IDs remain supported.
  • Reuse the notebook update lock, two drift checks, single update submission and readback reconciliation. Never execute notebooks/pipelines or change schedules.
  • Keep definitively failed/cancelled operations as failures; distinguish an accepted update's polling permission failure from rejection of the initial update request.
  • Expose 61 canonical / 50 read-only tools. Structural editing is hidden in read-only mode.

1.8.1 - 2026-10-01

  • Accept the legacy initialize/ping handshake over stdio (negotiating 2025-11-25 or 2025-06-18) so hosts such as Claude Code can connect. Discovery and Streamable HTTP remain 2026-07-28 only.

1.8.0 - 2026-09-17

  • Add fabric_list_onelake_files for bounded, paginated OneLake path listing under Files/ or Tables/.
  • Add fabric_read_onelake_file for exact-path byte-slice reads with auto/utf8/base64 encoding and truncation metadata.
  • Enforce fixed HTTPS DFS origin, byte caps (2 MiB listing, 1 MiB read, 64 KiB error) via streaming transport, and ETag If-Match on resumed reads.
  • Read-only tool surface: 60 canonical / 50 read-only tools. No SQL, Spark, Parquet decoding, or Delta snapshot reconstruction.

1.7.0 - 2026-09-15

  • Add full DataPipeline definition retrieval and guarded JSON Pointer patches below /properties.
  • Preserve unrelated properties, definition parts and display metadata; never run pipelines or change schedules.
  • Default to dry run, validate nested activity graphs, check drift twice and reconcile a single write by readback.
  • Distinguish rejected updates from permission failures while polling accepted operations.
  • Keep the existing pipeline summary contract stable; expose editing availability in capabilities.
  • Upstream atomic concurrency protection is unavailable; validation is structural, not execution proof.

1.6.0 - 2026-09-14

  • Add notebook definition/source retrieval and guarded cell-source replacements.
  • Preserve unrelated cells, metadata, attachments and definition parts; never execute notebooks.
  • Reject observed source drift, send one update, and verify or reconcile by readback.
  • Report notebook support, enablement and permission boundaries in capabilities.
  • Atomic concurrency protection is unavailable in the documented upstream API.

1.5.1 - 2026-09-14

  • Validate Foreach actions using their foreach field instead of incorrectly requiring expression; preserve nested-action and other control validation.
  • Add regression tests for valid loops, invalid sources, and nested failures.
  • Validate the staged release package, allowing arbitrary worktree folder names.

1.5.0 - 2026-08-25

  • Stop duplicating complete structured envelopes in tool text, preserving a concise summary and actionable error guidance while cutting the measured create-flow dry-run wire response by about 59%.
  • Add a flat typed registry for all 54 canonical tools and every opt-in tool, with compile-time handler/safety ownership, read-only filtering, domain scoping, and centralized list policies.
  • Standardize positive list bounds, defaults, paging facts, and timing diagnostics; make invalid configuration fail with actionable allowed values.
  • Replace the repeated Inspector process loop with a two-process persistent native smoke, make all 11 agent scenarios executable, and retain one real Inspector compatibility call.
  • Add a credentials-free Windows CI gate, targeted official MCP 2026-07-28 conformance scenarios, portable/OpenAI/skill validation, and a version-locked one-command release-candidate builder.
  • Explicitly disable ambient Dataverse configuration in packaged/example test profiles while preserving intentional validated opt-in and the existing unsupported Power Automate compatibility adapter.

1.4.1 - 2026-08-24

  • Enforce connector and operation-result limits locally when Microsoft's environment API ignores request bounds, and return total/returned/truncated paging metadata.
  • Add case-insensitive connector-name search and keep connector list rows to the promised name, display name, and tier fields.
  • Recheck connector, action/trigger, and deprecation filters locally, normalize trigger kinds, and use Microsoft's exact operationType for workflow JSON.

1.4.0 - 2026-08-24

  • Add three native read-only tools to list Power Automate connectors, search non-deprecated actions and triggers, and inspect exact operation parameters.
  • Use the environment-scoped Power Platform API with the existing Flow token; require no Dataverse product, connection mutation, or generic connector invocation surface.
  • Add strict environment-host derivation, exact-origin enforcement, bounded normalized results, non-retried operation search, native contract/client tests, and a live Inspector list/search/detail proof.

1.3.0 - 2026-08-20

  • Add trace-power-automate-submission, a reusable read-only workflow for tracing one exact correlation key across Power Automate runs, authoritative business records, and delivery artifacts.
  • Keep system-specific asset maps and completion rules in each system's runbook, and never treat missing or ambiguous evidence as permission to retry.

1.2.0 - 2026-08-11

  • Add power_automate_apply_guarded_patch for one to 64 ordered RFC 6902 add, remove, or replace operations under /actions.
  • Derive the complete target definition from a fresh live snapshot and preserve its complete connection-reference map without requiring either payload from the caller.
  • Return changed paths, validation details, and before/target hashes on dry run, then reuse the existing non-retried update, readback, and state-restoration lifecycle for approved live changes.

1.1.1 - 2026-08-11

  • Reconcile guarded-update activation with a fresh bounded flow readback when the activation request times out or errors, without retrying the definition update or activation request.
  • Treat a verified Started readback as successful restoration even when the activation response was ambiguous.
  • Preserve verified-definition, restoration-attempt, actual final-state, failed-phase, and safe-recovery details when activation does not complete.

1.1.0 - 2026-08-11

  • Add five read-only Microsoft Graph-backed Power Automate resource tools for SharePoint connector sources, document libraries, drive items, exact path/ID resolution, and verified Excel Run script action resource parameters.
  • Return current workbook, folder, file, and Office Script drive-item IDs plus drive-relative paths without requiring temporary picker actions or flows.
  • Verify source/drive ownership, current workbook/script existence, and file types before producing RunScriptProd or RunScriptProdV2 resource fields.
  • Add Microsoft Graph scope diagnostics, Graph pagination/origin protections, native tests, Inspector coverage, and live read-only resource proof.

1.0.1 - 2026-08-11

  • Reject deterministically malformed Workflow Definition Language expressions before guarded updates acquire a mutation lock or send any HTTP request.
  • Return the exact definition JSON pointer and character offset for local expression syntax failures, while preserving the local-only dry-run contract.
  • Share the same conservative expression validation with stopped flow creation.

1.0.0 - 2026-08-10

  • Replace the reference FastMCP implementation with one native Rust executable built on the official rmcp SDK.
  • Preserve the 44 original default tools and add native stopped-only power_automate_create_flow, for 45 default tools total. Preserve 16 optional aliases, four raw-TMDL tools, three Power Platform inventory tools, two Dataverse tools, public schemas, response envelopes, Azure CLI auth, and guarded Power Automate operations.
  • Target MCP 2026-07-28 exclusively with server/discover, complete-result metadata, private caching, standard resource contents, and stateless modern Streamable HTTP.
  • Package the Windows x64 executable directly in the Agent Plugin with no startup restoration or external runtime dependency.
  • Add Rust contract, schema, client, HTTP, mutation, package, and preserved agent-scenario tests plus Inspector 2.0 and real Codex acceptance.
  • Create Power Automate flows directly through the explicit unsupported api.flow.microsoft.com compatibility backend with complete local validation, dry-run by default, one non-retried POST, no Dataverse fallback, and exact disabled-flow readback.

0.3.0-beta.4 - 2026-08-10

  • Upgrade the portable runtime to FastMCP 4.0.0b2, including lighter startup imports and improved client interoperability.
  • Keep root mcp.json as the single portable MCP declaration used by the Codex Agent Plugins loader and other compatible clients.
  • Use uv's normal host-managed runtime cache instead of nesting it below plugin data, preventing cold-start installation failures on long Windows paths.
  • Install fastmcp-slim[server] for the portable runtime while keeping the full FastMCP distribution in development, so production declares the exact supported server surface without the client meta-package.

0.3.0-beta.3 - 2026-08-10

  • Launch a bundled Python wheel with fully pinned runtime requirements so first launch leaves ${PLUGIN_ROOT} unchanged and writes only beneath ${PLUGIN_DATA}.
  • Require a uv-managed Python 3.13 runtime, avoiding host-interpreter drift and project builds inside the installed plugin.
  • Launch the Inspector smoke through npm's JavaScript entry point so Windows execution policy does not block the harness.

0.3.0-beta.2 - 2026-08-10

  • Package the repository as an Agent Plugins 1.0.0 portable plugin.
  • Add a Codex compatibility manifest and a guarded Microsoft Fabric operator skill.
  • Launch the bundled MCP from the locked source with writable runtime state in ${PLUGIN_DATA}.
  • Keep MCP 2026-07-28, canonical domain-prefixed tools, and the complete read/write server surface.

0.3.0-beta.1 - 2026-08-05

  • Upgrade the server to FastMCP 4.0.0b1 and MCP SDK/types 2.0.0.
  • Adopt MCP 2026-07-28 across repo-owned runtime clients.
  • Verify the offline, protocol, Inspector, live-read, singleton, and rollback gates before activation.
