fix(mcp): resolve connected-tool lookups by workspace, not the process default - #5694
Conversation
Add `all_connected_tools_for_config` to resolve tools through a specific `Config` rather than the process-wide default host. This prevents test binaries from silently reporting no tools when multiple tests each open their own temporary workspace, since the ambient lookup returns `None` once a second host exists. A host that cannot be opened yields an empty list so that MCP unavailability does not fail tool listing. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a stub implementation of `all_connected_tools_for_config` in the MCP registry's stub module, and import the `Config` type in the connections module. This provides a no-op fallback when the MCP feature is disabled, matching the existing pattern for `all_connected_tools`. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `diagnostics_for_config` function was calling `registry_entries()` which reads connected-client tools from the process default workspace, but it should use `registry_entries_for_config(config)` to respect the provided configuration. This change adds a new function that accepts a config parameter and refactors the existing one to delegate to a shared implementation, ensuring diagnostics correctly reflect the tools available in the specified workspace rather than the ambient process default. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test `tool_registry_entries_include_connected_mcp_client_tools` was calling the ambient `registry_entries()` function, which resolves through the process default host. When other test cases in the same binary open a second host first, the ambient lookup returns `None` for the connected client tools. The fix switches to `registry_entries_for_config(&config)`, which correctly resolves through the config-scoped host that was used to establish the connection. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Reformatted the `all_connected_tools_for_config` function signature to split parameters and return type across multiple lines, improving code readability without changing any behavior. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `registry_entries_for_config` function was added to the `ops` module but not re-exported from the registry, making it inaccessible to external callers. This change adds the missing re-export so the function can be used as intended. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Add a new public function that allows dropping a connection when the caller already holds a Config reference, mirroring the existing pattern used by all_connected_tools_for_config. This avoids the by-server-id form's reliance on the process default host, which stops working once a second workspace is open, ensuring that callers who connected through connect can close over the same workspace. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test was calling the by-id disconnect function, which resolves through the process default connection rather than the config-scoped connection used elsewhere in the test. Changed to use the config-scoped disconnect to match the connection's actual scope and avoid test flakiness. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The connections module in the MCP registry stub now imports the Config type from the crate's config module, ensuring the stub build has access to the same configuration type used by the enabled build for consistent type handling across builds.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change scopes connected-tool and registry lookups to the requested workspace, and the targeted checks pass. However, the regression test does not directly construct a second workspace, so the multi-workspace failure mode is not fully exercised; merge is reasonable with explicit owner awareness or follow-up to strengthen that test.

…ool registry test Add a second workspace and server to the tool registry approval raw coverage e2e test to verify that config-scoped lookups do not leak tools from other workspaces. The new assertions ensure that each workspace's registry entries contain only its own server's tools and that the process default fallback does not incorrectly merge entries across workspaces.

Fixed a typo in a test comment where "测 test" was corrected to "actually test" to accurately describe the scoping behavior being verified by the assertions below. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test `tool_registry_entries_include_connected_mcp_client_tools` was passing the wrong config variable to `registry_entries_for_config`, causing it to check the default config instead of the one with the MCP client connection. This change corrects the argument to use `other_config`, ensuring the test verifies the intended behavior of including connected MCP client tools in the registry entries. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test was using `other_config` instead of `config` when calling `registry_entries_for_config`, which meant it was checking the wrong configuration for connected MCP client tools. This change fixes the reference to use the correct config variable so the test verifies the intended configuration. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

@coderabbitai Good catch on the outside-diff finding — addressed in You were right that the test could pass vacuously. With a single workspace open, The case now connects a second workspace and asserts isolation in both directions: each workspace sees its own server and, crucially, does not see the other's. Both are disconnected through their respective I verified the assertions have teeth rather than just passing: swapping the lookup to the wrong |

What
Adds a config-scoped counterpart to three MCP lookups that resolve through the process-wide default workspace, and points
diagnostics_for_configand one test at them.connections::all_connected_tools_for_config(&Config)all_connected_tools()connections::disconnect_for_config(&Config, &str)disconnect(&str)tools::registry::registry_entries_for_config(&Config)registry_entries()No new concept — this is the
diagnostics()/diagnostics_for_config()pair already intools/registry/ops.rs, extended to the calls underneath it.registry_entries()andregistry_entries_for_config()share one body.Why
registry_entries()reaches connected MCP tools throughconnections::all_connected_tools()thenhost::try_service(), which has noConfigand resolves viaresolve(DEFAULT_WORKSPACE, &hosts)insrc/openhuman/mcp/host.rs. That returns a host when the process default matches or when exactly one is open, andNoneotherwise.That is correct for the shipped app, which opens one workspace and sets the default in
mcp::init. It does not surviveraw_coverage_all, which globs everytests/raw_coverage/*.rsinto a single process: once two cases have each opened their owntempdir()workspace throughhost::for_config, the ambient lookup resolves toNoneand reports nothing connected.tool_registry_entries_include_connected_mcp_client_toolsconnects withconnections::connect(&config, &server)— which already names a workspace viafor_config— and then read back ambiently. It passed alone and failed beside its neighbours:Production semantics are unchanged.
list_tools()andget_tool()genuinely hold noConfigand keep resolving ambiently, and in a one-workspace process the two forms agree.Also fixed
diagnostics_for_config(config)was calling the ambientregistry_entries()— a config-scoped function reading a process-global registry. It now uses the config-scoped form, which is what its name already promised.How this surfaced
Rust Core Coverageis a changed-modules-only lane: it derives its target list from the diff, so a raw-coverage target nothing selects is never compiled or run. #5688 touchedsrc/openhuman/tools/andsrc/openhuman/memory/, which selected two targets that had rotted unnoticed — this one, and araw_coverage_allthat would not compile at all (fixed in that PR).That gap is worth a separate look: a broken raw-coverage target can sit green on
mainindefinitely until some PR happens to touch the right module.Verification
