feat(connectors): add Alpha Vantage MCP connector preset by Asymtode712 · Pull Request #3039 · arc53/DocsGPT

Asymtode712 · 2026-10-09T19:45:28Z

What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

Feature: Alpha Vantage MCP connector preset.
Why was this change needed? (You can also link to an open issue here)

Closes 🚀 Feature: Alpha Vantage MCP connector preset #2941
Agents can answer market questions after one OAuth sign-in: quotes, fundamentals, earnings, forex, crypto, commodities, economic indicators and news sentiment.

Changes:
- mcp:alphavantage in docsgpt/connectors/presets/mcp.yaml: mcp_oauth, capabilities: [read] (the only scope is alphavantage:read), category business.
- Icon at frontend/src/assets/connectors/alphavantage.svg. Alpha Vantage publishes no SVG logo, so this is their favicon mark redrawn in currentColor, like the other preset icons.
- settings.connectors.descriptions.mcp_alphavantage in all seven locales.
- Alpha Vantage added to the preset lists in Sources/Connectors/index.mdx and Tools/mcp-tools.mdx, including the self-hosted workaround below.
- New optional preset field default_actions. Tools on the list start on and the rest start Off. It's read in catalog.py and applied by apply_default_permissions in the three places a preset's tool gets its actions: the sign-in save, ensure_connection_tools and refresh. Presets without the field are unchanged.
- Tests for the preset, the YAML field, the permission defaults, and creating a preset's tool through ensure_connection_tools.

📝 Walkthrough

The change adds an Alpha Vantage MCP preset with configurable default actions. MCP setup applies those action defaults. Connector documentation and translations describe Alpha Vantage.

Changes: Alpha Vantage MCP connector

Layer / File(s)	Summary
Preset definition and default-action contract `docsgpt/connectors/catalog.py`, `docsgpt/connectors/presets/mcp.yaml`, `tests/connectors/test_catalog.py`	The catalog supports preset-specific default actions. The Alpha Vantage preset defines its OAuth, read-only connector details and selected default actions. Tests check the preset properties and action list.
Apply preset defaults to MCP actions `docsgpt/connectors/permissions.py`, `docsgpt/api/user/tools/mcp.py`, `docsgpt/connectors/mcp.py`, `docsgpt/connectors/service.py`, `tests/connectors/test_permissions.py`, `tests/connectors/test_tool_routes.py`	Permission initialization can mark actions outside a nonempty enabled list inactive. MCP save, rediscovery, and tool creation pass preset defaults. Tests cover default and non-default action permissions.
Connector listing and setup guidance `docs/content/Sources/Connectors/index.mdx`, `docs/content/Tools/mcp-tools.mdx`, `frontend/src/locale/*.json`	The connector pages describe Alpha Vantage, its sign-in restrictions, and setup alternatives. The locale files add Alpha Vantage connector descriptions.

Merge Risk: 🟡 Moderate · up to 91afd

Saving an existing MCP connector can reset tools a user turned on or off and can restore approval on write actions. The documented self-hosted Alpha Vantage setup places the API key in stored and displayed connector metadata. Both should be addressed before merge.

Full details: Linked Issues check

Explanation

Issue #2941 requires the Alpha Vantage preset, OAuth/read configuration, documentation, seven locale descriptions, default-action handling, and connector tests. The summary supports these changes and reports the required lint and connector test commands as passing. The summary also reports 21 YAML default actions while the current PR description says 22, and it reports that TOOL_CALL can still execute a tool switched Off. The issue's real-data checks with OpenAI and another provider are reported as TODO. The required icon is in frontend/src/assets/connectors/alphavantage.svg, which is excluded from review, so the icon requirement cannot be verified.

Resolution

Provide reviewable evidence for frontend/src/assets/connectors/alphavantage.svg, resolve the 21-versus-22 default-action discrepancy, and provide evidence that the OAuth connection works as an agent tool with real data through the required provider coverage.

Full details: Out of Scope Changes check

Explanation

The whole-PR summary reports that docs/content/Sources/Connectors/index.mdx adds CoinGecko to the curated MCP server list. Issue #2941 covers the Alpha Vantage preset and its supporting catalog, permission, localization, documentation, and test changes. The CoinGecko listing has no stated connection to that objective.

Hi @ManishMadan2882 , the PR is ready for review

Asymtode712 · 2026-10-10T09:59:54Z

Hey @dartpain @ManishMadan2882 ,

While testing this preset I found a problem in the MCP sign-in itself. It's not specific to Alpha Vantage, so I've kept it out of this PR and opened #3051 for it.

What happens: if you close the sign-in popup without finishing, the next sign-in attempt shows a blank popup that never reaches the provider's sign-in page. After a few cancelled attempts, a local macOS setup can hang for several minutes.

Why:

Each sign-in runs as mcp_oauth_task. The task waits up to 5 minutes in DocsGPTOAuth.callback_handler (max_wait_time = 300, docsgpt/agents/tools/mcp_tool.py) for a callback that never comes once the popup is closed.
Closing the popup only resets the frontend's state (cancel: finish in useMcpOAuth.ts). Nothing tells the server the attempt was abandoned.
On macOS and Windows, docsgpt worker uses Celery's solo pool, which runs one task at a time. Each abandoned attempt blocks the next sign-in for up to 5 minutes. The popup sits on about:blank until the worker gets to it.
Celery's time limits are only enforced in the prefork pool, so the task's soft_time_limit=600 doesn't help under the solo pool.

Workaround for local testing: stop the worker, run celery -A docsgpt.app.celery purge -f, and start it again.

None of the code in this PR is affected; I hit this only while recording the demo.

Preserve user-set action permissions when saving an existing MCP tool.

transform_actions sets active to True, and apply_default_permissions applies preset and approval defaults. On updates, carry_pins_between matches actions by name, but carry_pins copies only parameter values and filled_by_llm; it does not copy active or require_approval.

A save can therefore re-enable a user-disabled default action, disable a user-enabled non-default action, or restore approval for a write action. On updates, carry active and require_approval from the existing action by name after applying defaults. Apply preset defaults only to newly discovered actions.

+# Alpha Vantage only accepts redirect URIs on its allowlist (DocsGPT cloud) and

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Do not expose the workaround API key through the saved server URL.

If a self-hosted user follows this instruction, MCPServerSave.post retains server_url in storage_config and puts that URL in the tool description (docsgpt/api/user/tools/mcp.py, Lines 480 and 525-532). The API key can therefore appear in stored tool metadata and returned descriptions. The vendor also calls URL-based API-key authentication deprecated. Provide a supported credential path or redact the key from stored and displayed metadata, and warn users about the remaining request-log exposure. Based on learnings, a query-string token reaches server and proxy request logs before client-side redaction can run. (github.com)
