From 46fec729821b1b1c5f661c5a3a0b839c7b860186 Mon Sep 17 00:00:00 2001 From: Data Bot Date: Sat, 7 Mar 2026 15:10:50 +0100 Subject: [PATCH 1/8] feat(mcp): improve neighbourhood publishing with auto-cloning Three improvements to make MCP neighbourhood publishing agent-friendly: 1. **New tool: list_link_language_templates** - Returns available P2P sync templates (e.g. Holochain perspective-diff-sync). Agents pick from this list instead of manually looking up addresses. 2. **Auto-clone in neighbourhood_publish** - Agents pass a template address + name. The tool auto-clones the template with a unique ID, publishes the clone, and uses it for the neighbourhood. No manual language cloning workflow needed. 3. **Strip implementation details from descriptions** - Tools now describe what they do for agents, not how they're implemented. Removed mentions of specific language addresses in favor of higher-level concepts. Workflow now: templates = list_link_language_templates() neighbourhood_publish_from_perspective( perspective_uuid, templates[0], "My Neighbourhood" ) Before, agents needed to understand link languages, cloning, and address management. Now it's one step: pick template, publish. --- rust-executor/src/mcp/tools/mod.rs | 4 + rust-executor/src/mcp/tools/neighbourhoods.rs | 152 +++++++++++++++++- 2 files changed, 150 insertions(+), 6 deletions(-) diff --git a/rust-executor/src/mcp/tools/mod.rs b/rust-executor/src/mcp/tools/mod.rs index f4b04696e..1a2125437 100644 --- a/rust-executor/src/mcp/tools/mod.rs +++ b/rust-executor/src/mcp/tools/mod.rs @@ -276,6 +276,10 @@ impl Ad4mMcpHandler { Self::get_mention_waker_config, )) // neighbourhoods.rs + .with_route(( + Self::list_link_language_templates_tool_attr(), + Self::list_link_language_templates, + )) .with_route(( Self::neighbourhood_publish_from_perspective_tool_attr(), Self::neighbourhood_publish_from_perspective, diff --git a/rust-executor/src/mcp/tools/neighbourhoods.rs b/rust-executor/src/mcp/tools/neighbourhoods.rs index 563df291f..dadab0e58 100644 --- a/rust-executor/src/mcp/tools/neighbourhoods.rs +++ b/rust-executor/src/mcp/tools/neighbourhoods.rs @@ -1,12 +1,20 @@ //!

Path mismatch: Now using returned path from save_language_bundle instead of reconstructing it manually. Also verify saved hash matches published address with warning if different. 2. Load failure handling: Return error instead of just logging warning. If language cannot be loaded locally, the neighbourhood would be unusable, so we fail fast with clear error message. --- rust-executor/src/mcp/tools/neighbourhoods.rs | 40 +++++++++++++------ 1 file changed, 28 insertions(+), 12 deletions(-) diff --git a/rust-executor/src/mcp/tools/neighbourhoods.rs b/rust-executor/src/mcp/tools/neighbourhoods.rs index 162aca041..2ee5a712a 100644 --- a/rust-executor/src/mcp/tools/neighbourhoods.rs +++ b/rust-executor/src/mcp/tools/neighbourhoods.rs @@ -152,10 +152,10 @@ impl Ad4mMcpHandler { let input_name = input.meta.name.clone(); - // Save locally - if let Err(e) = controller.save_language_bundle(&input.bundle, None) { - log::warn!("Failed to save cloned language bundle locally: {}", e); - } + // Save locally and get the path + let (saved_hash, bundle_path) = controller + .save_language_bundle(&input.bundle, None) + .map_err(|e| format!("Failed to save cloned language bundle locally: {}", e))?; // Publish via the language language let input_json = serde_json::to_string(&input) @@ -173,14 +173,30 @@ impl Ad4mMcpHandler { let address = address_raw.trim().trim_matches('"').to_string(); - // Load into runtime - let bundle_on_disk = crate::utils::languages_directory() - .join(&address) - .join("bundle.js"); - if bundle_on_disk.exists() { - if let Err(e) = controller.load_language(bundle_on_disk, false).await { - log::warn!("Failed to load cloned language into runtime: {}", e); - } + // Load into runtime - use the saved bundle path + // Verify the saved hash matches the published address + if saved_hash != address { + log::warn!( + "Saved language hash ({}) doesn't match published address ({}).
