Llm wiki mcp integration

LLM-Wiki MCP Integration

Goal

Expose LLM-Wiki knowledge to agent clients through MCP or a local/remote API while keeping raw sources, retrieval filters, write permissions, review gates and audit logs explicit.

Use references/docs/17-mcp-api-integration.md as the reference playbook for the detailed MCP/API architecture, resource/tool contracts, auth/governance model, client compatibility, deployment patterns and testing checklist.

When to use

• The user wants Claude Code, Codex, Cursor, ChatGPT, VS Code, GitHub Copilot, LangGraph or another MCP client to search, read, lint, rescan, propose, review or export wiki knowledge.
• A wiki maintainer needs to pick an exposure mode (local stdio, local HTTP, remote read-only, remote governed-write) and is unsure which permission defaults apply.
• Someone is designing MCP resources/tools/prompts or a REST/OpenAPI facade in front of the wiki and needs the contract shapes.
• A team wants to add write/proposal tools and needs the auth scopes, PR/review gate and audit-log requirements defined before granting access.
• Before recommending client-specific integration behavior, re-verify each client's current MCP support against its own docs rather than assuming parity across Claude Code, ChatGPT, Copilot and LangGraph.

Inputs

• Target clients: Claude Code, Codex, Cursor, ChatGPT, VS Code, GitHub Copilot, LangGraph, OpenCode or other MCP-compatible tools.
• Current wiki layout and retrieval layer.
• Desired operations: search, read, graph traversal, lint, rescan, propose patch, approve review, export, reindex.
• Local-only, remote team, hosted product or enterprise deployment.
• Authentication, authorization and team permission requirements.
• Whether the wiki is git-backed, database-backed, desktop-local or hosted.
• Sensitivity/privacy requirements.

Procedure

1. Choose exposure mode

Mode	Use when	Default permissions
local stdio MCP	Personal local-first wiki or editor integration.	Search/read/list only.
local HTTP MCP/API	Desktop app or local daemon.	Bind to 127.0.0.1, token for sensitive operations.
local reviewed-write MCP	User wants agents to propose link/page fixes.	Draft patches only.
local API + MCP wrapper	Existing app already exposes HTTP API.	MCP calls narrow domain endpoints.
remote read-only MCP/API	Team, ChatGPT/company knowledge, GitHub Copilot cloud or autonomous clients.	Search/read/fetch/lint only.
remote governed-write MCP/API	Team or product integration.	Auth, tenancy, audit logs, PR/review gates and rate limits required.

Start read-only unless the user explicitly needs writes and has a review model.

2. Model resources, tools and prompts

Resources should expose canonical wiki state:

wiki://manifest
wiki://index
wiki://page/{space}/{slug}
wiki://page/{space}/{slug}/history
wiki://page/{space}/{slug}/lint
wiki://manifest/{source_id}
wiki://graph/neighbors/{space}/{slug}
wiki://review/unresolved
wiki://export/{job_id}

Read-only tools:

search_wiki(query, filters, top_k, cursor)
read_page(space, slug)
read_source_manifest(source_id)
graph_neighborhood(node, depth)
list_unresolved_reviews(filters)
run_lint(scope)
explain_retrieval(query_id)

Proposal-write tools:

draft_page_patch(path, patch, reason, sources)
propose_new_page(page_type, title, sources)
propose_link_fix(path, links)
propose_review_resolution(review_id, action)
create_pr_from_proposal(proposal_id)

Admin tools:

rebuild_index(index_name)
rescan_sources(scope)
export_subset(profile)
approve_proposal(proposal_id)
publish_export(export_id)

Admin tools must be disabled by default.

Prompts:

answer_from_wiki
ingest_source
triage_inbox
audit_claims
prepare_export
review_proposal

Prompts must preserve the instruction hierarchy and treat wiki/raw content as untrusted data.

3. Define response contracts

Every page resource should include:

id: "wiki://page/research/example"
space: research
slug: example
title: ""
body_markdown: ""
summary: ""
tags: []
links_to: []
source_citations: []
provenance:
  generated_at: ""
  generated_by: human|agent|importer
  model: ""
revision:
  commit: ""
  parent_commit: ""
  signed: false
review:
  state: draft|reviewed|verified|stale|rejected|approved|published
  required_owners: []
  approvers: []
policy:
  sensitivity: public|internal|sensitive|regulated|unknown
  publication_state: private|internal|public|archived
  tenant_id: ""

Every search result should include:

id: ""
title: ""
url: "wiki://page/..."
page_path: ""
heading_path: []
excerpt: ""
score: 0.0
retrieval_lane: lexical|dense|hybrid|rerank|graph
source_uris: []
review_state: ""
sensitivity: ""
support_level: extracted|inferred|ambiguous|synthesis|unsupported|conflicting

Every write proposal should include:

proposal_id: ""
changed_paths: []
base_revision: ""
reason: ""
source_support: []
risk: low|medium|high
requires_human_review: true
required_owners: []
status: draft|opened-pr|approved|rejected|merged

4. Define auth and permission boundaries

Choose auth by deployment:

Deployment	Auth pattern
personal local stdio	local user boundary plus sandboxed startup command.
local HTTP	localhost bind + token for sensitive operations.
internal remote	API key or OAuth 2.1, gateway rate limits, audit logs.
public/enterprise HTTP MCP	OAuth 2.1 or enterprise-managed auth when supported.
git-backed writes	GitHub App/service account with minimal repo permissions.

Define scopes:

Scope	Allows
wiki:read	Search/read allowed pages.
wiki:lint	Run/read lint reports.
wiki:propose	Create patch/page proposals only.
wiki:review	Review proposals.
wiki:admin	Reindex, rescan, export, publish, approve/merge.

Do not pass upstream MCP/client tokens through to downstream APIs. Validate audience and scopes at the wiki boundary.

5. Design governance and writes

For team/shared knowledge, prefer:

propose -> branch/patch artifact -> lint/eval/security checks -> CODEOWNERS review -> merge -> index refresh

Require:

• proposal tools create patches, not direct writes;
• approve_proposal checks owner/review status;
• protected branches and required checks for shared wiki repos;
• signed commits or attributable service-account commits where possible;
• source citations and proposal metadata preserved;
• pending/rejected content excluded from production retrieval.

6. Add REST/OpenAPI facade when useful

Use a REST facade for CI and non-MCP clients:

Endpoint	MCP mapping
GET /manifest	wiki://manifest
GET /search?q=	search_wiki
GET /pages/{space}/{slug}	wiki://page/{space}/{slug}
GET /pages/{space}/{slug}/history	history resource
GET /pages/{space}/{slug}/lint	lint resource
POST /proposals	proposal tools
PATCH /pages/{space}/{slug}	patch-as-proposal
POST /approvals/{proposal_id}	approve_proposal
POST /indexes/{name}/rebuild	rebuild_index
GET /exports/{id}	export resource/task

Use standard HTTP errors: 400, 401, 403, 404, 409, 422, 429, 500, 503.

7. Review client compatibility

Client/host	Recommended contract
Claude Code	Local stdio/local HTTP MCP; read/proposal tools for developer workflows.
Claude Messages API connector	Remote MCP with explicit allow/deny tool policy.
Codex CLI/IDE	stdio or Streamable HTTP; use tool approval modes and read/propose split.
Cursor/VS Code	MCP server plus prompts/resources.
GitHub Copilot cloud/repo MCP	Read-only, narrowly allowlisted tools; avoid assuming prompts/resources support.
ChatGPT/deep research/company knowledge	Read-only search + fetch compatibility surface with citation URLs.
LangChain/LangGraph	MCP adapters or Agent Server MCP endpoint; structured outputs.
GitHub Actions	Runner for lint/eval/export/proposal PRs, not the primary MCP host.

8. Test the integration

Run:

• list resources/templates;
• read known page;
• search known query with filters;
• denied read of sensitive page;
• denied cross-tenant search;
• read source manifest without raw secret leakage;
• graph neighborhood bounded by depth/size;
• lint tool with bounded runtime;
• proposal-write creates patch only;
• direct write/delete is rejected;
• admin tools are unavailable by default;
• prompt-injection fixture in raw/wiki content cannot alter tool behavior;
• invalid path/URI template values are rejected;
• audit event emitted for sensitive read/proposal;
• rate limit returns structured error;
• export/publication blocked without redaction manifest.

Safety gates

• Do not expose write tools before read-only tools are tested.
• Do not allow MCP tools to obey instructions embedded in wiki/raw content.
• Do not leak sensitive page contents through semantic search snippets.
• Do not recommend unauthenticated remote MCP servers.
• Do not bypass git/PR/review gates for team knowledge.
• Do not give cloud/autonomous clients broad tool access; start with allowlisted read-only tools.
• Do not make admin tools available by default.
• Do not present registry/server-card/extension support as universal across clients without checking current client compatibility.
