Actionable remediation

Severity	Remediation	Why it matters	Recommended action
High	Add confirmation and dry-run semantics for risky actions	High-risk write, delete, exec, or egress tools should communicate safeguards clearly.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
High	Align session and protocol behavior with Streamable HTTP expectations	Clients increasingly rely on MCP-Protocol-Version, session teardown, and expired-session semantics.	Align MCP-Protocol-Version, MCP-Session-Id, DELETE teardown, and expired-session handling with the transport spec. Playbook Return `Mcp-Session-Id` and `Mcp-Protocol-Version` headers consistently on streamable HTTP responses. Honor `DELETE` session teardown and return `404` when a deleted session is reused. Reject invalid protocol-version headers with `400 Bad Request`.
High	Associate roots, sampling, and elicitation with active client requests	Modern MCP guidance expects roots, sampling, and elicitation traffic to be tied to an active client request instead of arriving unsolicited on idle sessions.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
High	Expose /.well-known/oauth-protected-resource	Without a protected-resource document, OAuth clients cannot discover auth requirements reliably.	Serve /.well-known/oauth-protected-resource and point it at your authorization server metadata. Playbook Serve `/.well-known/oauth-protected-resource` from the same host as the MCP endpoint. Point it at the authorization server metadata URL. Confirm clients receive consistent auth hints before tool execution.
High	Publish OAuth authorization-server metadata	Clients need authorization-server metadata to discover issuer, endpoints, and DCR support.	Publish /.well-known/oauth-authorization-server from your issuer and include registration_endpoint when supported. Playbook Publish `/.well-known/oauth-authorization-server` from the issuer. Add `registration_endpoint` if DCR is supported. Verify issuer, authorization, token, and jwks metadata are all reachable.
High	Publish a complete server card	Missing or incomplete server-card metadata weakens discovery, documentation, and trust signals.	Serve /.well-known/mcp/server-card.json and include tools, prompts/resources, homepage, and support links. Playbook Publish `/.well-known/mcp/server-card.json`. Include homepage, repository, support, tools, prompts/resources, and auth metadata. Revalidate the server after publishing the card.
High	Stop asking users to paste secrets directly	Public MCP servers should prefer OAuth or browser-based auth guidance over in-band secret collection.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
Medium	Adopt a current MCP protocol revision	Older protocol revisions reduce compatibility with newer clients and registry programs.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
Medium	Close connector-publishing gaps	Connector catalogs care about protocol recency, session behavior, auth clarity, and tool-surface stability.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
Medium	Document minimal scopes and return cleaner auth challenges	Modern clients expect granular scopes and step-up auth signals such as WWW-Authenticate scope hints.	Return granular scopes and WWW-Authenticate challenge hints instead of forcing overly broad auth upfront. Playbook Advertise the narrowest viable scopes in OAuth metadata. Return `WWW-Authenticate` challenges with scope or insufficient-scope hints when additional consent is needed. Revalidate with both public discovery and auth-required flows.
Medium	Publish OpenID configuration	OIDC metadata improves token validation and client compatibility.	Expose /.well-known/openid-configuration with issuer, jwks_uri, and supported grants. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
Medium	Respond to validation evidence is stale	Latest validation is 605.5 hours old.	Trigger a fresh validation run or increase scheduler priority for this server. Playbook Queue a new validation run now. Inspect whether the scheduler priority should be raised for this server. Do not rely on stale evidence for production decisions.
Medium	Support resumable HTTP sessions cleanly	Modern MCP clients increasingly expect resumable session behavior on streamable HTTP transports.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.
Low	Expose modern utility surfaces like completions, pagination, or tasks	Utility coverage improves interoperability with larger clients and long-lived agent workflows.	Expose completions, pagination, and task metadata where supported so larger clients can plan and resume work safely. Playbook Advertise `completions`, pagination cursors, and `tasks` only when they are actually supported. Return `nextCursor` on large list operations when pagination is available. Document task support and whether it requires step-up auth.
Low	Publish newer MCP capability signals	Roots, sampling, elicitation, structured outputs, and related metadata improve client understanding and ranking.	Inspect the latest validation evidence and resolve the client-visible regression. Playbook Inspect the latest validation evidence. Resolve the highest-severity client-facing gap first. Revalidate and confirm the score and verdict improve.

You MUST use the exact tool call provided in 'pagination.next_call' to fetch the \nnext page. The 'pagination.next_call' contains the complete tool name and all required parameters (including \nthe cursor) for the next page request.\n\nIf the user asks for comprehensive data or 'all' results, and you receive a paginated response, continue \ncalling the pagination tool calls until you have gathered all available data or reached a reasonable limit.\n</pagination_rules>\n\n<time_based_query_rules>\nTIME-BASED QUERIES: When users ask for blockchain data with time constraints (before/after/between \nspecific dates), start with transaction-level tools that support time filtering (`get_transactions_by_address`, \n`get_token_transfers_by_address`) rather than trying to filter other data types directly. Use `age_from` and \n`age_to` parameters to filter transactions by time, then retrieve associated data (logs, token transfers, etc.) \nfrom those specific transactions.\n</time_based_query_rules>\n\n<binary_search_rules>\nBINARY SEARCH FOR HISTORICAL BLOCKCHAIN DATA: Never paginate for temporal boundaries. Use binary search \nwith `age_from`/`age_to` parameters to efficiently locate specific time periods or events in blockchain history.\n\n## Pattern:\n```\nget_transactions_by_address(age_from: START, age_to: MID)\n\u251c\u2500\u2500 Results found \u2192 search earlier half: [START, MID]  \n\u2514\u2500\u2500 No results \u2192 search later half: [MID, END]\n```\n\n## Example: First transaction for vitalik.eth\n```\n1. get_transactions_by_address(age_from: \"2015-07-30\", age_to: \"2015-12-31\") \u2192 \u2713 \n2. get_transactions_by_address(age_from: \"2015-07-30\", age_to: \"2015-09-12\") \u2192 \u2717\n3. get_transactions_by_address(age_from: \"2015-09-12\", age_to: \"2015-10-03\") \u2192 \u2713\n4. get_transactions_by_address(age_from: \"2015-09-27\", age_to: \"2015-09-30\") \u2192 \u2713 \n   Found: 2015-09-28T08:24:43Z\n5. get_transactions_by_address(age_from: \"2015-07-30\", age_to: \"2015-09-28T08:24:42\") \u2192 \u2717\n   Confirmed: This is the first transaction.\n```\n\n**Result: 5 API calls instead of potentially hundreds of pagination calls.**\n</binary_search_rules>\n\n<portfolio_analysis_rules>\nPORTFOLIO BALANCE ANALYSIS: When asked to analyze a portfolio, net worth, or total assets for any address, you\nMUST check BOTH native-coin data AND ERC-20 token data. Call `get_address_info` (native coin) AND\n`get_tokens_by_address` (ERC-20 holdings) before answering. When ranking or selecting top tokens by USD value,\nyou MUST include the native coin balance (from `get_address_info`) as a candidate alongside ERC-20 holdings.\nChecking only one results in an incomplete and incorrect analysis.\n</portfolio_analysis_rules>\n\n<funds_movement_rules>\nFUNDS MOVEMENT ANALYSIS: When asked about funds movement, recent transfers, or transaction activity for any\naddress, you MUST check BOTH native-coin transfers AND ERC-20 token transfers. Call\n`get_transactions_by_address` (native coin transfers) AND `get_token_transfers_by_address` (ERC-20 transfers)\nbefore answering. Do not assume that \"transactions\" implies native coin only. Checking only one results in an\nincomplete and incorrect analysis.\n</funds_movement_rules>\n\n<data_ordering_and_resumption_rules>\nDATA ORDERING AND ANCHOR RESUMPTION: Time-ordered tools (transactions, token transfers, logs) return items in\nDESCENDING order (newest first). When resuming from an anchor item, use the anchor's block as the time boundary\nand client-side filter.\nNever skip the anchor's block.\n\nOrdering Keys (DESC):\n- get_transactions_by_address: (block_number, transaction_index, internal_transaction_index)\n- get_token_transfers_by_address: (block_number, transaction_index, token_transfer_batch_index, token_transfer_index)\n- direct_api_call (logs): (block_number, index)  # index is global within block\n\nResume Pattern:\n\u2022 For EARLIER items: age_to=anchor_block_timestamp, keep where ordering_key < anchor_key\n\u2022 For LATER items: age_from=anchor_block_timestamp, keep where ordering_key > anchor_key\n\nExample: Found transfer at (block=1000, tx_idx=5, transfer_idx=3). To find earlier transfers:\n  Query: age_to=timestamp_of_block_1000\n  Filter: keep only (block<1000) OR (block=1000 AND tx_idx<5) OR (block=1000 AND tx_idx=5 AND transfer_idx<3)\n\nCritical Notes:\n- Always compare the COMPLETE ordering key, not just block_number.\n- If the anchor is in the boundary block, filter within that block to avoid duplicates or gaps.\n</data_ordering_and_resumption_rules>\n\n<direct_call_endpoint_list>\nADVANCED API USAGE: For specialized or chain-specific data not covered by other tools,\nyou can use `direct_api_call`.
