* fix(mcp): handle Claude Code GET probe and make stateless_http configurable (#751)
Claude Code v2.1.84+ sends a GET to /mcp/ before POST initialize,
which fails with 405 (stateless) or 400 (stateful). Intercept
sessionless GET requests in MCPMiddleware and return 200 OK so the
client proceeds to POST initialize.
Also make stateless_http configurable via HINDSIGHT_API_MCP_STATELESS
(default: false/stateful) instead of hardcoding true.
Closes#751
* docs: add HINDSIGHT_API_MCP_STATELESS to configuration reference
Add optional filter_mcp_tools() method to OperationValidatorExtension.
Called during tools/list after bank-level mcp_enabled_tools filtering.
Extensions can override to hide MCP tools per-user-per-bank based on
access policies. Default returns all tools unchanged.
- Add filter_mcp_tools to OperationValidatorExtension with default pass-through
- Wire into _get_enabled_tools in _apply_bank_tool_filtering
- Move _ALL_TOOLS to mcp_tools.py to avoid circular import (re-exported from mcp.py)
- Fail-open: if filter raises, log warning and return unfiltered tools
- Enforce ceiling: validator can narrow but never expand beyond bank config
- Add 8 tests: default, filtering, empty set, integration, composition,
can't-add-tools, exception fail-open, no-validator passthrough
* fix: MCP tool calls fail when MCP_AUTH_TOKEN and TENANT_API_KEY differ
When both HINDSIGHT_API_MCP_AUTH_TOKEN and ApiKeyTenantExtension are
configured with different values, MCP transport auth passes but tool
execution fails because the MCP token gets re-validated against the
tenant API key in the engine layer.
Add mcp_authenticated flag to RequestContext so the engine skips tenant
re-validation when MCP transport auth already succeeded.
Fixes#627

* test: strengthen assertion to verify no auth error in tool response
The original test only checked that "banks" key existed in the response,
which was true even for error responses like {"error": "...", "banks": []}.
Now asserts "error" not in parsed to properly catch auth failures.

Some MCP clients (e.g., Claude Code) don't send an Accept header,
causing the MCP SDK to reject requests with 406 Not Acceptable. The
middleware now ensures Accept includes application/json and
text/event-stream when missing.

* feat: introduce hindsight-api-slim and hindsight-all-slim packages
Closes#552
- Move all source code from hindsight-api/ to new hindsight-api-slim/
- hindsight-api-slim has heavy ML deps (torch, sentence-transformers,
transformers, einops, flashrank, mlx, mlx-lm, safetensors) and
pg0-embedded as optional extras: [local-ml], [embedded-db], [all]
- hindsight-api becomes a zero-code meta-package depending on
hindsight-api-slim[all] for full backward compatibility
- Add hindsight-all-slim meta-package: hindsight-api-slim + client + embed
- hindsight-all updated to depend on hindsight-api-slim[all]
- pg0.py: lazy-import pg0 with clear ImportError pointing to [embedded-db]
- Dockerfile: replace sed hack with proper uv sync --extra flags
- Update release.yml, test.yml, lint.sh, release.sh, CLAUDE.md and
all path references throughout the repo
* refactor: rename hindsight/ directory to hindsight-all/
* docs: document hindsight-api-slim and hindsight-all-slim package variants
Add package variants table and extras explanation to installation.md
* docs: remove emojis from installation.md, use professional tone
* docs: link Docker slim variant to pip package variants section
* docs: consolidate Docker image variants into single table
* ci: fix working-directory paths after package restructure
- Replace all hindsight-api → hindsight-api-slim in test.yml
- Replace hindsight → hindsight-all in test.yml
- Add --extra embedded-db to test-embed API install step
* ci: add local-ml and embedded-db extras to API sync steps
These extras were previously implicit in the old hindsight-api package
(which bundled everything). Now that hindsight-api-slim uses optional
extras, we must explicitly request local-ml and embedded-db in CI.
* ci: add API install step with embedded-db to test-embed smoke test
The smoke test starts hindsight-api as a daemon, which requires pg0-embedded.
Add a dedicated install step for hindsight-api-slim with embedded-db extra
so the daemon can start successfully.
* ci: remove --no-install-project when using optional extras
When --no-install-project is combined with --extra, the optional deps
are not installed because extras require the project to be active.
Remove --no-install-project from steps that need local-ml or embedded-db.
* ci: fix ordering of uv sync steps to preserve optional extras
When uv sync runs for a different workspace member, it removes optional
extras installed for other members. Fix by always running extra-requiring
API sync last, after other workspace member syncs.
Also remove --no-install-project from embedded-db sync in test-embed,
as --no-install-project prevents optional extras from being active.
* ci: add local-ml extra to test-embed API install for smoke test
The smoke test starts the full API server which needs sentence-transformers
for local embeddings (default provider). Add local-ml extra to the install.
* ci: simplify extras with --all-extras and add slim pip smoke test
- Replace explicit --extra local-ml --extra embedded-db with --all-extras
for cleaner, more maintainable sync steps
- Add test-pip-slim job: tests hindsight-api-slim[embedded-db] without
local ML models, using Cohere for embeddings/reranking (mirrors Docker
slim smoke test approach)
* ci: simplify slim smoke test to health check only (mirrors Docker test)
